Hydroelectric power is great because water is great and so is electricity but not together and at the same time, that's dangerous.

Gas Presentation Plan

-How gas is produced (types of production)

Natural gas is the UKs largest generator of energy quite significantly. Fossil fuels formed from the remains of ancient plants and animals. The process is usually used to extract natural gas in which fractures in the Earth's surface are opened and widened by injecting water, chemicals, and sand at high pressure. Also called hydraulic fracturing.

-Percentage of gas used in U.K. for power (how important it is relied on)

80% of the UK’s 25 million homes are powered by gas – and around a quarter of the country’s electricity is generated by gas-fired power stations.

This means gas, along with other energy sources like wind, solar and nuclear, plays a key role in the UK energy mix.

In recent years, natural gas (NG) is the fastest growing primary energy source in the world. NG is widely available, and it is the cleanest burning petroleum based fuel.

-Pros

CO2 emissions of natural gas is the lowest of all petroleum based energy sources, which makes it favourable considering the ever growing threat of global warming

It is very reliable and works 24/7

About 30% of UK energy in 2015 was generated by gas

Gas plants are one of the most flexible ways to generate electricity, as they can rapidly provide power during periods of high demand

(Also, importing gas from other countries strengthens international relationships)

2.2x10^7 joules of energy produced for a pound of gasoline-more than coal
Very cheap to produce

Woodfuel and Energy Crops: burning wood from forests and woods is an extremely useful source of energy. It is:

Renewable - all the wood and crops can be replanted easily

Carbon Neutral - biomass energy uses a carbon cycle - all plants and wood are replanted, therefore the carbon dioxide levels are never increased

Huge supply - in the UK, there is plenty of forests and woods to burn wood from, and vast fields to grow and burn densely energised crops

Cheaper than Most Fossil Fuels - see the graph above

There are 2 main uses for solar energy: direct electricity conversion through photovoltaic cells and water heating through solar panels.
There are many pros to Solar Energy. First and most, it is renewable and free and abundant (so long as we have the sun in the sky).

theTidal energy is created by trapping water in dams and then releasing water into turbines and harnessing kinetic energy from the moving water.
-Renewable: the energy source is a result of the gravitational fields from both the sun and the moon, combined with the earths rotation around its axis- thus it will not run out.
-Tidal currrents are highly predictable and their cycles are well known. Thus we will be able to determine the rate at which the water should be let out for maximum efficiency.
- Effective at low speeds. Water is 1000 times denser than air which it possible to generate electricity at low speeds.
-Low lifespan: tidal energy plants have long lifespans, this ultimate lay reduces the cost these power plants can sell electricity for, making tidal energy more cost competitive.
As an example, the tidal barrage power plant la rance, was opened in 1966 and still generates large amounts of electricity.
- Green- tidal energy is very environmentally friendly. It doesn't emit any climate changing gases. It also doesn't take up a lot of space.
However there are few examples of tidal plants and thus their effects are not as known. Thus a good investment by UK forever meant would be to study the environmental effects of the tidal power plant.
There are three main disadvantages.
They are expensive.
They are close to land.
They have negative environmental effects.
The main current known negative effect is that a tidal plant relies on the manipulation of ocean levels. This may alter marine life's habitats.
However if the UK government invests in research technological solutions will resolve some of these issues, which are currently being developed.
Tidal power plants need to be constructed close to land, hopefully in a few years we can exploit weaker tidal currents at locations further out in the sea.
The methods of generating electricity from tidal energy is a relatively new technology. It ispredicted that if the U.K. government invests in researching tidal energy, tidal power plants will be commercially profitable within 2020 with better technology and larger scales.
Firstly, the U.K. government should invest in researching the negative effects of tidal power plants and how they can be reduced. If it found the tidal plants are green, then further funding should be given to begin development of tidal power plants along the UK coastline
