The table shows the trends how investment changes in some areas in UK.  The data shows investment to solar energy, wave energy, nuclear energy, and hydroelctric
power via river all experienced a decrease between 2006 to 2010, and it is likely that this is a result of financial crisis in 2008.Coal mining, which remains relatively stable around 0.1 billion pounds from 2004 to 2014. Higher than any other areas, deep sea oil drilling and hydroelectric power via received investment for 69 billion pounds in average between 2004 and 2014, while both coal mining and hydroelectric power via rivers are below 0.3 billion pounds. This phenomenon might relate
to the degree of difficulty to develop those energy.

Table 1  shows the changes of amount investment in energy sources by UK government from 2004 to 2014. During this period, there were significant variations in different area of investment. Investment for nuclear energy and deep sea oil drilling were the largest and most consistent investments which both average approximately 69 billion pounds per year. It was almost 600 times higher than the least investment of coal mining which annual investment never over 0.11 billion pounds for 11 years. Renewable energy’ investment increased generally for these years but with a sharp drop in 2010. Money for solar energy and wave energy both reached peak around 30 in 2014. However the amount of hydroelectric power via rivers only rosed to 0.36 billion pounds.
These variations in investment was likely to result from a series of reasons. One possible explanation of this situation could be the raised awareness of the environment in UK, and it also can could explain the minimal investment in coal mining for smaller CO2 emissions. Furthermore, because of the special weather British has its own advantages to use wind resource. In addition, the science and technology were able to support the choice as renewable sources are much reliable compared with others.

Methane is a kind of gas, which naturally presents in atmosphere, with rising momentum due to human activities. Similarly, CO2 is also a kind of gas and presents in atmosphere with growing momentum in light of human activities. Mathane differs from CO2 in term of main production and natural processes. The former is mainly produced by decomposing organic substances and can transform into CO2 by natural processes while the latter is mainly produced by human burning fossil fuels and can transform X into CON2 by natural processes.

Exercise 14

As is vividly illustrated in the picture, it describes the total amount of investment in various area from 2004 to 2014. In general, the amount of investment increased each year and reached their peak at 2014. The major investment are deep sea oil drilling and nuclear engergy which grew from 68 and 69 to 71 and 70 billions of pounds respectively between 2004 and 2014. Besides, wind energy, solar energy and wave energy are subordinate investment which reached 47, 30 and 27  billions of pounds separately in 2014. Finally, the amount of investment in coal mining and hydroelectric power via rivers are relatively small, which reached 0.1 and 0.36 billions of pounds in 2014. All in all, it is believed that the development of those area will continue thrive since the picture shows a good momentum.

Similarly, methane and CO2 are made from gas and naturally present in atmosphere. Both of their landing system are of low visibility due to human activity. Methane is mainly produced by decomposing organic substances, unlikely, CO2 is by human burning fossil fuels. Natural processes can transform into CO2 in making methane, by contrast, it’s not suitable for another.

Exercise 14

The table shows the total amount of money invested by the UK government in terms of different energy sources from 2004 to 2014. During the decade, the total investment saw an increase trend, although the money invested in every type energy was fluctuated. Obviously, the nuclear power and deep sea oil drilling are two largest investment. The investment applied to the solar energy was almost as much as the wave energy.

As for the coal mining and hydroelectric power, the investment of both only occupies a slight proportion of the whole funds, below 0.11 and 0.36 respectively. Additionally, the renewable energy sources investment need grew during the eleven-year period, despite a decline in 2010. Although the trend of the wind investment has risen dramatically during the decade, peaking at 47 billion, the funds invested to it was still far behind which spent on either nuclear energy or oil drilling.

The table demonstrates the variations of government investment among energy sources in UK from 2004 to 2014.

2. Methane is the same as carbon dioxide with respect to their increasing levels due to human activities.

3. Methane comes into being mainly owing to the decomposing of organic substances, whereas, carbon dioxide comes from a great deal of burning fossil.

Exercise 14
Table 1 illustrates the UK’s investments in seven types of energy sources from 2004 to 2014. Overall, energy investment mainly witnessed an increase during this period, whereas, the amount of investments did fluctuate from 2008 to 2012 in the field of deep sea oil drilling, wave energy, coal mining and so on. In addition, the amounts invested in coal mining and hydroelectric power via rivers were similar and far less than other types, with only 0.1 billion and 0.36 billion pounds respectively in 2014. Regarding the growth speed, the UK government paid more attention in exploring wind energy, since there is an apparent rise, nearly doubled, within ten years. In contrast, the investment in coal mining, hydroelectric power via rivers, nuclear energy and deep sea oil energy had a subtle ascent during this period. It is likely that these types of energy investments will continue increase in the following years. One possible reason for this trend may due to the global proposal that suggests more clean energy to be used in dealing with the warming earth.

The figure provided reveals the total amount invested in billions of pounds sterling in different areas of investment from 2004 to 2010. The investments in clean energy increased dramatically with most of them doubling except nuclear energy. On the contrary, investments in fossil fuels as well as nuclear energy remained roughly the same. This may be due to several factors such as rapid development of technology, rising awareness of environmental protection, though are need for fossil fuels has remained the same if not increased.

2. Methane is mainly produced by decomposing organic substances, whereas carbon dioxide is generated by human burning fossil fuels.

3. Methane can be transformed into carbon dioxide by natural processes, however, the opposite is not possible.

Exercise 14
The table demonstrates a variety of investment in energy sources by UK government from 2004 to 2014. During the period, there are significant variation in the amount of different investment.

The super investment is nuclear energy and deep sea oil drilling that both achieve the average amount of 69 billion pounds per year, which is approximately 600 time higher than that of coal mining and hydroelectric power via rivers, with the number of around 0.11 billion and 0.22 billion respectively. Generally, the number invested in the majority of energy sources had a obvious rise in the period, whereas, it experienced a dramatic decline at 2010. Wind energy, in particular, had reached a remarkable growth of 22 billion via these years. Similarly, investment in solar and wave energy had increased by 15 and 13 billion respectively.

Types of factors have caused the above changeable phenomenon. The possible reason for the noticeable upward trend for renewable energy is that British government is gradually conscious of sustainable development and protection of the environment, and this also result in the less using of natural resource coal mining. In addition, it’s likely that nuclear energy and oil drilling in deep sea are offered high provision essentially due to the updated technology and economic support. Moreover, surrounding by water, the British is possible to use wind and wave to generate energy. However, lacking of strong tides in the UK has caused the less attention on hydropower.

To sum up, there is some comparatively risings of investment in renewable energy sources in Britain, it would occur mainly the result of the increasing awareness for creating eco-friendly environment.

Exercise 14

The table shows the amount of money which UK government invested in energy sources between 2004 and 2014. Overall, the total amount of investment by UK government in all areas were increased, although the fluctuation of each area is different. The majorities of the investment were in deep sea oil drilling and nuclear energy, each of them was invested approximately 69 billion every year. The lowest investment is in coal mining, which was not over 0.1 billion during the period. The amount of investment in renewable energy sources such as solar energy, wind energy and wave energy areas increased rapidly from 2004 to 2014, although there was a decrease in 2010. In contrast, the amount of investment in non-renewable energy sources like the oil drilled from deep sea was stable during the period. Although the investment in renewable energy resources increased rapidly, the total amount of it was still less than that in non- renewable energy sources.

There were some likely reasons for these variations. The increase of the investment in renewable energy sources was probably caused by increasing environmental awareness of British government and British citizens, that was also the reason of the non-growth of the investment in non-renewable energy sources. Additionally, the increasing amount of investment of wave energy and wind energy may because the special geographic position of British which was an island country full of wave and wave energy. Furthermore, although the science and technology is developing rapidly, machines using non-renewable energy weren’t be replaced by machines using renewable energy quickly, cars and machines in factories still needed much non-renewable energy, as a result, the majorities of the investment were in deep sea oil drilling and nuclear energy.

Methane and CO2 are similar because they are both gas which naturally present in atmosphere. In addition, Methane's levels are up due to human activity, so as CO2's. Methane is mainly produced by decomposing organic substances and can be transformed into CO2, while CO2 is mainly produced by human burning fossil fuels and natural processes and cannot be transfromed.

Exercise 14
Table 1 illustrates the investment in energy sources from 2004 to 2014 by UK government. During this time, the quantities varied. The largest payment is in nuclear energy and deep sea oil drilling, with the amount of averaging about ￡69 billion per year. And this is around 600 times higher than the average of coal mining and 200 times higher than hydroelectric power via rivers , with the average amount of ￡ 0.11 billion and ￡0.36 per year respectively. The investment in wind energy, solar energy and wave energy were at the middle level but have significant increase. Wave energy and solar energy are quiet similar for approximately ￡18 billion per year. In contrast, wind energy acquired more funding of around ￡37 billion per year.

These variations may have a lot of reasons. The increase in renewable sources of energy may inspired the citizens to pay attention to the environmental issues, and it may have the same reason as the decrease of coal mining. In addition, the nuclear and deep sea oil drilling have the steadily cost may because the government is still search for the technology to replace them. When renewable sources become reliable, the found might be transferred.

Exercise 14
The table gives information about the UK  government's investment in various energy sources from 2004 to 2014. Apparently,the UK

government

invest different amount of money in a variety of sources. Most capital is invested to deep sea oil drilling and nuclear energy with average around 68 billion pounds per year  respectively,which was about 600 times more than the  least investment of coal mining,which never exceed 0.11 billion pounds.And the maximum of capital spent on hydroeletric power via rivers each year was only 0.36 billion pounds. Investment in solar energy saw a fluctuative growth in this years period and reached 30 billion pounds in 2014.The similar trend also happened in that of wave energy and wind energy.And the investment of wind energy ,whose peak was at 47 billion pounds in 2014,was about twice that of wave energy.

The variation of investment in different energy sources is caused by several  reasons.One possible reason is that an increasing number of citizens in Britain have had the awareness of environment protection so they are tend to choose some clear and renewable energy to reduce the emission of greenhouse gas like CO2. Besides,the rise of investment in wind energy may be due to the special weather-a lot of windy days in the UK.In addition,the advanced technology is probably another factor that support the research and usage of renewable source of energy.

Exercise11

Methan is similar to CO₂ in terms of the aspects that they are both naturally present in atmosphere but the levels of both have been increasing due to human activity. Methane can be transformed successfully by natural processes, however, the same way is not suitable for CO₂. In addition to that, Methane is mainly produced by decomposing organic substances, whereas CO₂ is produced by human burning fossil fuels.

Exercise 14

The table shows the total amount of money invested by the government in terms of different energy sources between 2004 and 2014. During the decade, the total investment saw an increase trend, although the money invested every type energy was fluctuated. The nuclear power and deep sea oil drilling are the largest investment, with each of these averaging approximately 69 billion per year. The investment applied to the solar energy was as much as the wave energy, but the amount invested to each of these two items was less than 25% money invested in solar energy.

As for the coal mining and hydroelectric power, the investment of these two items only occupies a slight proportion of the whole funds, below 0.11 and 0.36 respectively. Additionally, the renewable energy sources investment grew during the eleven-year period, despite a decline in 2010. Although the trend of the wind investment rise dramatically during the decade, peaking at 47 billion, the funds invested to it was still far behind the pounds spent on either nuclear energy or oil drilling.

Exercise 14

The table demonstrates the variations of government investment among energy sources in UK from 2004 to 2014.

During this period, the trend of a majority of money which were distributed to energy sources by British changed drastically. The largest investments were nuclear energy and deep see oil drilling, maintaining over 66 billion per year. Following by wind energy, it was experienced a fluctuating upward approximately from 25 to 47 billion. Although solar energy and wave energy had a similar trend with wind energy, they kept under 30 billion per year. In terms of investment in coal mining and hydroelectric power via rivers, they occupied the smallest figure, with about 0.1 billion every year.

There were several reasons that could explain the variations. The dramatic increase in solar, wave, wind and nuclear energy was due to the emphasis of environmental awareness in UK. In addition, coal mining might rise CO2 emissions which probably may cause global problems such as the increase of sea level and the glacier melting.

Methane is a kind of gas and presents in atmosphere. Similarly, carbon dioxide is also gas and exists in atmosphere. However, Methane is mainly produced by decomposing organic substances, but Carbon dioxide is the result of human being fossil fuels. In addition, though methane can be transformed in to Carbon dioxide in natural processes, the methane cannot be got by this way.

Ex 14
The table above represents the variation of amount invested by UK government in energy sources between 2004 and 2014.

The data provided shows that this decade witnessed an increase of financial support from the United Kingdom in all areas related to energy sources except coal mining. A possible reason was that the improvement of economy accelerates the increase of financial revenue, offering opportunities for the resource exploitation. As we can see from the table, the proportion of investment to Coal mining and hydroelectric power via rivers is the least, varied below 0.4 billion pounds whereas the investment in deep sea oil drilling and nuclear energy were enormous, with the number reaching over 70 during this period.One explanation for that might be the governmental focus on sea and nuclear resources which were limited than others in the decades, hence these two areas are put at the top list in funding projects. Besides, the growth of funds in solar energy was significant, with the number reaching at 30 in 2014 which is twice bigger than that in 2004. The similar trends are also seen in the wave energy and hydroelectric power via rivers. This might due to the fast development of these areas requiring more capital to be exploited. At the same time, the amount of investment in deep sea oil drilling and nuclear energy barely changed, revealing the steady investment of UK government.

Overall, for UK government, the sea oil sources as well as nuclear sources were both the emphasized areas in terms of giant potential whilst the investment in other resources were also added to improve economy to a high level during the decade started from 2004.

Exercise 14
Table shows the amount of money that the UK government invested in different energy sources from 2004 to 2014. Obviously, British government invested the capital in different sources of energy varied drastically. Nuclear power and drilling for oil at sea took up the largest and most consistent investments, with average approximately 69 billion pounds per year respectively. This was almost 600 times higher than the least investment of coal mining which annual investment never exceeded 0.11 billion pounds. Investment in renewable energy sources (solar energy, wave energy and wind energy ) generally rised between 2004 and 2014, while with a sharp drop in 2010. Investments in solar energy and wave energy both increased to the peak (around 30) in 2014. By contrast, although hydroelectric power via rivers increased to over twice much (0.36) during this period, it still was the second smallest investments of all.
These variations in investment was likely to result from a series of reasons. One possible reason of this situation could be that the UK government raised thier awareness of the environment, and this could explain its minimal investment in coal mining for smaller CO2 emissions. In addition, wind sources is a feature of Britain where owns frequently windy weather. Furthermore, the development of science and technoloogy might be infulence British on choosing the renewable sources since they had ability to research these resources.

3. Methane can be transformed into CO2 by natural processes, but the opposite is not possible.

Exercise 14

Table 1 gives the information of UK government investment in various energy sources in 2004-2014. It is obvious that investments in nuclear energy and deep sea oil drilling were the largest areas, consisting approximately 70 billion per year respectively, which is almost 600 times higher than the least investment in coal mining. Investments in solar energy, wave energy and wind energy maintained the middle position. In addition, three of them showed an increase trend during this period, and figures nearly doubled in 2014. Although the investment in hydroelectric power via rivers raised more than two times, it still was the second smallest area of all.

There were series of reasons could result in  these significant variations. One possible reason of this situation might be that UK government had increased awareness of environment pollution causing by traditional energy, such CO2. Furthermore, the development of science and technology could influence people on choosing the renewable source, since they have the ability to research more environmental and eco-friendly energy.

Exercise 14
The table shows that changes of British government investment in Energy Sources from 2004 to 2014. During this decade, there were a lot of variations in the area of investment.The amount money of that UK government invested in solar energy increased almost twofold over the period, with 15 million pounds in 2004 and 30 in 2014, as did wave(14 in 2004 and 27 in 2014) amd wind energy(25 in 2004 and 47 in 2014). Besides, it is clear that the largest investment were in drilling for oil at deep sea and nuclear energy, with each part of those is around 70 million pounds per year. On the contrary, coal mining got the smallest investment from UK government.Although there is some fluctuations, the figures remaind steable at 0.1 between 2004 and 2014.The second small part is the expenditure on hydroelectric power.It showed a remarkable increase and   peaked at 0.36 by 2014.

These different changes might be drove by various factors. The renewable sources of energy is used more and more currently. One possible reason for this could be increasing environmental awareness of British and this could also explain the minority of investment in coal mining.Furthermore, the special windy and rainy weather in UK might be another reason for investing in wave and wind energy. What’s more, depending on the advanced technology, it made it possible to use solar and nuclear energy effectively.

Overall, total investment in all areas of investment showed an upward trend, although the change was different. The fluctuation of amount invested of wave energy is very similar to that of hydroelectric power via rivers , the number of which rose to 20 billion pounds and 0.32 billion pounds in 2008. However, it fell sharply in 2010 to 14 billion and 0.12 billion pounds sterling, down by 30 percent and 62.5 percent,and gradually increased to 27 billion and 0.36 billion pounds over the next four years. By contrast,investment in coal mining and deep sea oil drilling fluctuated slightly. In addition, the number of investment in deep sea oil drilling and nuclear energy were highest,71 billion pounds and 70 billion pounds respectively in 2014. The total amount invested of coal mining and hydroelectric power via rivers differed from others, with merely 0.1 billion and 0.36 billion pounds. One possible reason might be that both sectors have the lowest economic returns for the country.

Exercise 14
The table shows the total amount of seven kinds of energy sources  which are invested by the government in UK between 2004 and 2014. The figures in nuclear energy and deep sea oil drilling were the highest among many areas of investment in 2004, reaching 69 billions and 68 billions respectively. They were both decreased to around 66 billions in 2010 and then increased to the top point. By contrast, the investments in coal mining and hydroelectric power via rivers are still the lowest from 2004 to 2014. Above these numbers, they fluctuated around the average during the past 10 years.
These variations in investment could be a result of many factors. The dramatic increase of renewed energy like solar energy, wave energy, wind energy and hydroelectric power via rivers  may be due to the environmental awareness in UK, although dirty energy still played the dominant role.

Exercise 14

The table shows the information about UK government investment in energy sources from 2004 to 2014.

Deep sea oil and nuclear were the most popular energies in UK. Ii is likely that these energies could figure out the energy shortage. Therefore, Britain saw similar increases both in the investment in deep sea oil drilling(68 billions of pounds in 2004 to 71 billions of pounds in 2014) and nuclear energy(69 billions of pounds in 2004 and 70 billions of pounds in 2014) despite fluctuation during this period. Total amount invested in wind energy grew from 25 billions of pounds to 47 billions of pounds. The same rising trend also embodied in solar energy and wave energy, although there was a decline during 2008 to 2012. One possible explanation may be that the UK government invest more money in other indispensable areas such as public services and arts.

In contrast, coal mining and hydroelectric power via rivers were not attached much importance by government due to the possible reasons that the output of coal was harmful to environment and hydroelectric power was not very effective. And the investment in these two areas were both below 1 billions of pounds in this decade.

In summary, all of these figures were rising. Solar energy and wind energy is predicted to increase significantly because these energies are clean and possess huge exploiture potenials.

During this period, investment in deep sea oil drilling and nuclear energy was the biggest parts, and the amount almost remained the same at 70 billion  with only a little fluctuation. It might be the reason that demand from such sources is huge and steady.

Wind energy gradually received more investment from 25 in 2004 to 45 in 2008, then it went through a decline in the next year. But it reached its peak in 2014. Similarly, solar energy increased from 15 in 2004 to 22 in 2008 and reached a peak after one year’s decrease, and wave energy experienced a similar tendency. The decline in year 2010 may due to bad economic environment.

The table gives information about UK government investment in energy sources between 2004 to 2014. During this period, the largest investment was put on both nuclear energy and deep sea oil drilling, while the lowest is coal mining and hydroelectric power via rivers. Although the funds on solar energy and wave energy have considerably increased, they are only less than half of the nuclear energy.
There are some possible reasons for those above. The fact that less increases on deep sea oil drilling and nuclear energy may be is a result that government is exploring the techniques which less costly. Furthermore, one possible explanation for the little investment on coal mining could be that the government has the awareness of environment protecting. Another reason for the consisting increasing investment on wave energy, solar energy and wind energy might be that sustainable development is emphasized by government in UK. Overall, the investment on different areas reflects the science and technology development level of a country.

Similarly, the figure of wave energy showed the same trend as it went up to 27 billion pounds in the year of 2014. In contrast, the figure of hydroelectric power via rivers has experienced the smallest rise. One possible reason is sources like wave energy and wind energy are sustainable and environmental. And the awareness of environment protection and sustainable renewable energy is more clear in today’s society. The number of Deep sea oil drilling and nuclear energy made up majority of the investment, both over 65 billions pounds from 2004 to 2014. These two sources occupied a lot of investment in that they are both represent country’s power and development.

This chart shows the differences of investment in seven energy sources in the UK from 2004 to 2014. Overall, the data shows that all traditional energy sources were less invested, such as coal and hydroelectric power with only 0.1 and 0.15 billion investment, although the latter one had an increase and even been invested more than triple, compared to the coal in 2014. However, sources supported by high-tech had always received the largest investment, patially because of their special needs to get rid of the danger. For example, deep sea oil drilling, which needs many drills and computers to ensure the security, have to spend large money investment. So as the nuclear energy, which has more than double financial support than wind energy and developed steadily in this 10-year period.

Natural energies had the second large investment, there were 36 and 20 billion pounds in average invested in wave and wind areas. Although an remarkable increase and decrease happened in 2006 and 2010. But solar energy had a greatest increment, which investment doubled in 2014.

Overall, traditional energies had the least investment, whereas the hightech and dangerous energy areas have been largely invested, although these sources had some rises or drops.

Methane and CO2 are both gas that can naturally present in atmosphere. As methane is mainly produced by decomposing organic, CO₂ is mainly produced by human burning fuels. Furthermore, they can all be transformed into CO2 through some natural processes and their levels have been rising due to human activities.

Exercise 14

The table shows the information about the total amount that the UK Government invested in energy sources from 2004 to 2014. It is easy to find that all of them were increased during those ten years. And the nuclear energy and deep sea oil drilling have the largest amount of energy investment. On the contrary, coal mining and hydroelectric power via rivers occupied a small proportion.

The table illustrated the information about the total investment in energy source in UK. The investment in deep sea oil drilling, wind energy, wave energy and nuclear energy account for the majority. By contrast, money invested in coal mining and hydroelectric power via rivers was not quite obvious. Moreover, that in deep sea oil drilling take the first place and the nuclear is the second only to sea oil.

In specific, that of deep sea oil drilling and nuclear energy keep stable around 70 million. There was rapid increase in wind energy investment to 45 million between 2004 and 2008 before decreasing sharply to 30 million in 2010 after which, it rose constantly to 47 million in 2014. In wave energy and solar energy, the trends are similar.

Exercise 14

Table 1 depicts the amount of money that the UK Government invested in energy sources from 2004 to 2014. During this period, there were significant variations in the amount of money invested by the British government in different areas. The largest investments were in deep sea oil drilling and nuclear power. Government invested each of them about 69 billion in average per year. Coal miming had the lowest investment in all energy sources, with never rising above 0.11 billion. Investment in renewable energy sources generally rised between 2004 and 2014, with the exception of a dramatic fall in 2010. The amount of money invested in solar energy, wave energy and wind energy almost doubled in 2014 compared to 2004, they are still less than that of oil and nuclear. And the hydroelectric power via rivers reached its highest point at only 0.36 billion.

A variety of factors resulted in these variations in investment. The UK’s frequent wind combined with its small rivers might explain the different investments in wind energy and hydroelectric power via rivers. What’s more, the UK’s increasing awareness of the environment implications of high CO2 emissions might result in the general increase in renewable sources of energy and the minimal investment in coal miming. Because oil and nuclear power are more conventional and reliable, more funds will be taken to these areas.

Methane and CO₂ are both gases which can be naturally present in atmosphere. Furthermore, they can all be transformed into CO₂ through some natural processes and their levels have been rising due to human activities. The methane is mainly produced by decomposing organic substances, which is unlike that CO₂ is mainly produced by human burning fossil fuels./ the methane differs from CO₂ with regard to their main way of production.

Exercise 14
The table 1 compares the total amounts of investment by UK government in all sources of energy from 2004 to 2014.

It is clear that the nuclear energy and deep sea oil drilling have the largest amount of energy investment; However, coal mining and hydroelectric power via rivers only account for a slightest share of government energy spending, both of which remains at a lower level since 2004.

The energy funding that goes to the field of the nuclear energy and deep sea oil drilling has been stabilized at an average of 68 billion of pounds sterling. This amount of spending is followed by that of wind energy, wave energy and solar energy. All these energy sources saw an increase of about a half in the investment up to 2014. One of the reasons for this rise may be due to the increasing awareness of government about the value of clean energy and sustainable development. In contrast, the investment on energy from the coal mining and hydroelectric power via rivers has been on a lower level from 2004 to 2014, which might be as a result of the technological advance in developing alternative energy or the concerns about the problem of pollutions after the mine exploring.

To sum up, energy investment made by the UK government is becoming more reasonable, with increasing amount of money spent on the new and clean energy and positively searching for the alternative and the diversification of energy.

Methane is a kind of gas and presents in atmosphere. Similarly, carbon dioxide is also gas and exists in atmosphere. However, Methane is mainly produced by decomposing organic substances, but Carbon dioxide is the result of human being fossil fuels. In addition, though methane can be transformed in to Carbon dioxide in natural processes, the methane cannot be got by this way.

Exercise 14

This table shows the total amount that the UK Government invested in energy sources from 2004 to 2014. Overall, the money invested into difference sources of energy varied dramatically. Among them, the government invested most in nuclear energy and deep sea oil drilling, with approximately 69 billion per year. In addition, investment in renewable resources all increased, including solar energy, wave energy, wind energy and hydroelectric power via rivers . However, in 2010, these resources experienced a sharp decline, and investment for all of them were still less than that of oil and nuclear. Solar and wind energy got up to about 30 million per year, whereas the most fund hydroelectric power via rivers was only 0.36 billion. Unlike the above, the investment in coal mining was the lowest, with only around 0.1 billion per year.

There are several probable explanations for this situation. The UK's increasing awareness of protecting environment may the main reason for the increased investment in renewable energy, and this can also explain its minimal investment in coal mining. In addition, one possible reason for the UK's continued high investment in nuclear and drilling energy might be they need more financial support to solve difficulties of technology.

Methane is identical to CO2 in that they are gases.

Methane is the same as CO2 with regard to natural appearance in atmosphere.

Methane is unlike CO2 in that it is produced by decomposing organic substances while CO2 mainly come out by human burning fossil fuels.

Methane can be transformed into CO2 in natural processes. CO2 is different in that it is unable to be transformed into itself.

The level of methane is rising , that is also true for CO2, owing to increase human activities.
Exercise 14
The table above represents the variation of amount invested by UK government in energy sources between 2004 and 2014.

The data provided shows that this decade witnessed an increase of financial support from the United Kingdom in all areas related to energy sources except coal mining. A possible reason was that the improvement of economy accelerates the increase of financial revenue, offering opportunities for the resource exploitation. As we can see from the table, the proportion of investment to Coal mining and hydroelectric power via rivers is the least, varied below 0.4 billion pounds whereas the investment in deep sea oil drilling and nuclear energy were enormous, with the number reaching over 70 during this period.One explanation for that might be the governmental focus on sea and nuclear resources which were limited than others in the decades, hence these two areas are put at the top list in funding projects. Besides, the growth of funds in solar energy was significant, with the number reaching at 30 in 2014 which is twice bigger than that in 2004. The similar trends are also seen in the wave energy and hydroelectric power via rivers. This might due to the fast development of these areas requiring more capital to be exploited. At the same time, the amount of investment in deep sea oil drilling and nuclear energy barely changed, revealing the steady investment of UK government.

Overall, for UK government, the sea oil sources as well as nuclear sources were both the emphasized areas in terms of giant potential whilst the investment in other resources were also added to improve economy to a high level during the decade started from 2004.

Exercise 14

Table 1 shows the money UK government invested in different energy sources between 2004 and 2014. There were various energy sources that UK government invested, and during the period huge changes occurred. Investment in renewable resources like solar energy, wave energy, wind energy and hydroelectric power via rivers all increased. For example, investment in solar energy was 15 billion of pounds sterling in 2004, while in 2014, the amount increased to 30 billion. Among these energies, the government invested most in wind energy. Besides, the government invested about 70 billion in both deep sea oil drilling and nuclear energy, which was highest among these investments. Unlike the above, the investment in coal mining was the lowest.

There were several possibly reasons to explain this situation. One explanation that investment increased in renewable energy might be the awareness of environmental friendly development. The government invested more in renewable resources to protect the environment, which was also the reason why the investment in coal mining was the lowest. The highest investment in wind energy among renewable resources may result from the weather in UK.

Methane and CO2 are similar because they are both gas which naturally present in atmosphere. In addition, Methane's levels are up due to human activity, so as CO2's. Methane is mainly produced by decomposing organic substances and can be transformed into CO2, while CO2 is mainly produced by human burning fossil fuels and natural processes and cannot be transfromed.

Exercise 14
Table 1 illustrates the investment in energy sources from 2004 to 2014 by UK government. During this time, the quantities varied. The largest payment is in nuclear energy and deep sea oil drilling, with the amount of averaging about ￡69 billion per year. And this is around 600 times higher than the average of coal mining and 200 times higher than hydroelectric power via rivers , with the average amount of ￡ 0.11 billion and ￡0.36 per year respectively. The investment in wind energy, solar energy and wave energy were at the middle level but have significant increase. Wave energy and solar energy are quiet similar for approximately ￡18 billion per year. In contrast, wind energy acquired more funding of around ￡37 billion per year.

These variations may have a lot of reasons. The increase in renewable sources of energy may inspired the citizens to pay attention to the environmental issues, and it may have the same reason as the decrease of coal mining. In addition, the nuclear and deep sea oil drilling have the steadily cost may because the government is still search for the technology to replace them. When renewable sources become reliable, the found might be transferred.

Compared to other energy resources, the major amount of the capital was invested in deep sea oil driling, increasing slightly to 71 billion pounds, and the investment remained the high level from 2004 to 2014. Similarly, a sum of capital injectd into nuclear power generation also accounted for a major part of the government investment.

Unlike nuclear energy, a sharp increase trend in total amount of capital in wind energy can be seen, jumping from 15 to 47 billion pounds. The figure for the investment in hydroelectric power via waves and rivers are similar to wind energy with ragard to the climbing trend, rose almost double. However, the porportion of expenditure in hyfroelectric power via rivers contributed a small slice of the total amount, rosing from 0.15 to 0.36 billion pounds.

Methane is a kind of gas that naturally presents in atmosphere. This is also true for CO2, since it is the one of the components of air. Besides, the level of both of them has risen due to human activities. But they are dissimilar in that the former usually produced by decomposing organic substances, while the latter is mainly generated through burning fossil fuels by human. Methane is unlike CO2 in that the former can transform into the latter during natural processes.

Exercise 14

Table 1 gives information about total investment in energy sources by UK government from 2004 to 2014. During this ten-year period, all areas of investment experienced fluctuation more or less and most of them showed similar trends in most of years. Both deep sea oil drilling and nuclear energy received largest proportion of total amount invested among areas of investment. These two areas are also quite similar in that money invested in them saw few changes with an average amount of ￡69 billion per year. By contrast, the government did not pay much attention to propping up coal mining obtaining no more than ￡0.11 billion per year and hydroelectric power via rivers with investment at most ￡0.36 billion per year. Amount of funding from investment in wind energy, solar energy and wave energy were at the middle level but slight difference existed among them. Wind energy was unlike the latter two in that it acquired more funding of around ￡37 billion per year compared to approximately ￡20 billion per year for solar energy and ￡18 billion per year for wave energy.

There are several possible reasons for the data and trends above. First of all, nuclear power and deep sea oil drilling are relatively new fields that require advanced technology and have beneficial prospects in many areas like environmental protection; thus, they are more expensive and UK government is willing to provide more funding for them. Secondly, technology of coal mining is mature and this type of energy is declining since it gives rise to many environmental problems like global warming, while hydroelectric power via rivers cannot be popularized due to UK’s terrain; therefore, amount of investment in these two was much less. Next, wind energy, solar energy and wave energy have not been widely used yet but they are going to play important roles in life and production so certain amount of funds with a growing trend has been put in them. Overall, as renewable and clean energy sources (nuclear energy, wind energy, solar energy and wave energy) show advantages of long-term interest for the environment and human beings, more funds have flown in these areas.

Exercise 6

1. There were approximately 22 million learners of English as a foreign language in 2001, whereas in 2004, the number had risen to over 28 million.

2. There was an increase of around six million in the number of learners of Chinese as a foreign language from 2001 to 2004.

3. The number of foreign language learners studying English in 2001 was around 10 million, but, by 2004, this number had increased to approximately 40 million.

Exercise 11

1. Methane is similar to CO2 with regard to one type of gas and they are both naturally present in atmosphere.

2. Methane is mainly produced by decomposing organic substances, whereas CO2 is by human burning fossil fuels.

3. The natural processes of methane can transform into CO2, but CO2 cannot.

Exercise 14

The table chart illustrates the amount of British government investment in seven kinds of energy areas from 2004 to 2014. The dramatic variation can be seen in different energy sources during that time. The highest-cost area were deep sea oil drilling and nuclear power, which were invested about 70 billion per year, whereas the lowest one was coal mining, from 0.05 to 0.1 billion. Another area invested less is hydroelectric power via river, which peaked at only 0.36 billion. The amount invested in solar energy and wave energy were quite similar as they both increased since 2004 and experienced a sudden drop in 2010. However, they finally achieved approximately two-fold higher after a decade (2014), at 30 and 27 billion respectively. Although wind energy increased the most during that time, a significant fluctuant was showed, standing at 35 billion in average.

Plenty of reasons can be considered resulting this situation. High demand and effective technology of investing renewable resources like oil and nuclear areas might arouse the attention of the UK government so that they put most of the money. In addition, the equipment of solar energy, wave energy and wind energy might be cheaper, also these kinds of areas had become essential part of energy original. Comparatively, coal mining and hydroelectric power may lead to a bad environment and affect people’s health, so they just occupied a small portion of total amount.

Exercise 6
1.There were approximately 22 million learners of Chinese as a foreign language in 2001, whereas in 2004, the number had risen to approximately 28 million.
2.There was an increase of around 6 million in the number of learners of Chinese as a foreign language from 2001 to 2004.
3.The number of foreign language learners of English in 2001 was around 11 million, but, by 2004, this number had increased to approximately 44 million.

Exercise 11
Methane and CO2 are both gases which are naturally present in atmosphere, and their increasing levels are due to human activity. However, their production is different. Methane is mainly produced by decomposing organic substances. In contrast, CO2 is a product caused by human burning fossil fuels. In addition, although Methane and CO2 both can be transformed into CO2 via natural processes, the opposite of Methane is not possible.

Exercise 14
Table 1 shows the amount of money that the UK Government invested in energy sources between 2001 and 2014. During this period, the government invested different kinds of energy sources, which varied dramatically. Deep sea oil drilling and nuclear energy were poured into the most of money, approximately 69 billion per year. Compared with coal mining and hydroelectric power via rivers, their investment only 0.04 billion and 0.12 billion per year respectively. Investment in renewable energy sources increased steadily during 2004 to 2014, except the investment in 2010. The amount of money invested in wind energy  increased dramatically, from 25 billion to 47 billion., but it was still less than deep sea oil drilling and nuclear energy. The variations in investment may resulted from different kinds of factors. An increasing number of investment in renewable energy mainly reflected the UK Government awareness of the importance of renewable energy, because carbon dioxide may pose a threat to public health, such as the production of coal mining combustion. In addition, the weather of the UK are mainly windy and rainy, so using these weather advantages to produce energy is effectively and it can avoid the situation of the lack of sunshine as well. The scientists and researchers dedicated to renewable energy studies sustainably, they may found that these energy is more environmental-friendly. During 2010, because of the global economic crisis, the amount of money invested in renewable energy dropped to some extent. Renewable energy is applied widely and people become more reliable to them.

The Methane and carbon dioxide are similarly classified into gas. Both substances exist in atmosphere. Methane is mainly produced by decomposing organic matter while the carbon dioxide is accompanied with human's burning fossil fuels. Carbon dioxide can be transformed from methane through natural process whereas methane can not be acquired by the same way. In addition, the human activity can lead to the increase in the level of both of them.

The table gives information about the total investment in energy source in UK.
The investment in deep sea oil drilling, wind energy, wave energy and nuclear energy account for the majority of the financial resources. By contrast,the coal mining and hydroelectric power via rivers make up the  quiet small percentage. what is more, the deep sea oil drilling take the first place and the nuclear is second only to sea oil.
The level of deep sea oil drilling and nuclear energy keep stable around 70 million. There are obvious changes can be seen in wind energy, increasing significantly from 25 million to 45 million between 2004 and 2008,then it decreasing sharply to 30 million in 2010. Afterwards, it rising constantly to 47 million in 2014. The similar changes take place in  wave energy and solar energy.

Methane is a kind of gas and naturally presents in atmosphere. Similarly, carbon dioxide is also gas and exists in atmosphere. However, they are quite different in terms of the way of production. Methane is mainly produced by decomposing organic, whereas Carbon dioxide is produced by human burning fossil fuels. Carbon dioxide can be transformed from methane through natural process while methane cannot be attained in the same way. Nevertheless, the increase of both is due to human activities.

This table shows the total amount invested in different areas from 2004 to 2014. Overall, the data shows total funds on all areas have saw a rise, except for coal mining whose investment was the same as that in 2004 though there were slight fluctuation during these 10 years. In terms of deep sea oil drilling and nuclear energy, there were a slight rise from 68  to 71, 69 to 70 respectively, but, the expense of them are always higher than that of others. In contrast, solar energy and wave energy and hydroelectric power via rivers had experienced a dramatic increase and finally almost doubled their original data. Although wind energy did not rise rapidly, it has saw a relatively moderate increase from 25 to 27.

There may be various explanations for these disparities. One explanation is that deep sea oil drilling and nuclear energy need more financial support due to their difficult technology and work environment. However, coal mining and hydroelectric power via rivers are much simpler than others and therefore they spent less money, but, government invested more funds on the later because it is more environmental-friendly. Similarly, solar energy, wave energy and wind are also sustainable method to produce energy without environment damage; so the government increased their budgets.

Exercise 14
The table 1 illustrates the investment made by the UK government on energy source during a decade (2004-2014).

While the figures for energy source investment fluctuated over the period shown, it is clear that compared with coal mining, the lowest number(0.1 billion) in 2004 that never increased over 0.11 billion in the table, the nuclear power and drill for oil at deep sea occupied the highest number, 68 and 69 billion respectively from the start. Except for the slight drop in 2010, both these two areas rose to around 70 in 2014.There was a great leap in the investment of environmental-friendly resources between 2004 and 2014 apart from a slight decease occurring from 2010 and 2012. The wind power enjoyed the third rank in the chart,peaking at 47 billion and solar energy ensued with 30 billion. Although the rise appeared in hydroelectric power, it still received small amount of investment from the government, only 0.36 billion.

The reasons of causing this situation may vary. It is undeniable that the great amount of electricity still is produced by nuclear power and oil although the UK government invested a great deal of money on green powers because of increasing awareness of environment. That is also the reason why the resource like coal mining emitting a lot of CO2 or other harmful chemicals received little finance. Furthermore, the UK experiences more frequent rainy and windy weather so the government holds numerous budget to develop advanced technology for optimizing the power from wind and wave as well as rivers. Finally, in spite of a slight fall between 2010 and 2012,which may be resulted from an economic recession, we still can see the UK government spares no effort to invest sustainable energy.
