In 1980, 42% of total energy came from oil, followed by 26% from natural gas. Standing at 33%, the share of oil has decreased significantly in the 1980s . Following this trend, the share of natural gas has also decreased slightly to 25%.The trends in coal and nuclear power are quite different from those described above. While the share of hydroelectricity remained stable at 5%, the share of coal and nuclear power increased from 22% to 27% and from 5% to 10% respectively during the mentioned period.

Overall, in both years, the most significant sources of energy was oil, which accounts for almost half the sources of energy, while hydroelectric power and nuclear power was the least amount of energy sources in the USA. In all sources of energy there was only minimal change over the 10 year period

In 1980, oil which accounts for 42%, was the main source of energy in the USA, followed by 26% from natural gas. Over the 10 years, from 1980 to 1990,  the share of oil has decreased significantly from 42% to 33%. Following this trend, the share of natural gas has also fallen slightly to 25%.

Contrary to the trend of oil and natural gas, the trend of coal and nuclear power tends to increase. The share of coal and nuclear power increased from 22% to 27% and from 5% to 10% respectively during the mentioned period. Especially, the share of hydropower which remained stable at 5%, was the lowest in both two years.

Overall, it is clear that oil and natural gas were downward trends while the opposite was true for coal and nuclear power. On the other hand, oil was the biggest in both two years whereas hydroelectric power was always last throughout the period.

Overall, an upward trend was seen in coal and nuclear power, while the opposite was true for oil and natural gas over the period of 10 years starting from 1980. Additionally, oil ranked first among the energy sources throughout the period, whereas hydroelectric energy remained the lowest in both years.

The two pie charts below provide information about the main sources of energy  in the USA  in the 1980s and the 1990s.

# data[].attributes.body
In 1980, oil was the main energy source in the USA which was 42%, followed by 26% of natural gas. Then coal supplied more than 20 percent of power demand in the USA while hydroelectric power and Nuclear power both supplied 5% of the total energy.
After ten years, Nuclear power produced one-tenth of full power demand and that was almost double that it was in the previous decade. The hydroelectric power as an energy source remained unchanged as it provided 5% of total energy demand in this decade also. The two other main sources of energy in the USA remained almost unchanged in this decade and those two sources were Coal and Natural Gas. Finally, the use of oil as an energy source reduced to 33%, which is almost 10% less than the previous decade but remained the largest source albeit the reduction in this 90s decade.

Overall, it is clear that natural gas and oil followed a downward trend, while the opposite was true for coal over the period of ten years from 1980 to 1990. Additionally, natural gas ranked first among energy resources throughout the period, whereas hydroelectric power remained the lowest in both years

# data[].attributes.body
Overall, natural gas and oil followed a downward trend, while the opposite was true for coal over the period of ten years from 1980 to 1990. Additionally, natural gas ranked first among energy resources throughout the period, whereas hydroelectric power remained the lowest in both years.

# data[].attributes.body
The use of nuclear power as a source of energy increases and it produced 10% energy in the 1990 which was double than the percentage of energy production from this source in the 1980 ,whereas the production of energy from oil decreased from 42% to 33%. In 1990, the proportion of coal was 22% before increasing to 27% and the use of natural gas was 26% before decreasing to 25%.
However, Hydroelectric power as an energy source in the USA remained constant in both 1980 and 1990 at 5%

# data[].attributes.body
In 1980, 42% of total energy resources came from oil, followed by 26% of natural gas. There was a significant fall in the proportion of oil, stood at 33% over the period of ten years from 1980 to 1990. Following this trend, the percentage of natural gas saw a slight decline at 25%.
The trends for coal and nuclear power were remarkably different from those described above. The proportion of hydroelectric power stayed the same at 5%, while the percentage of coal and nuclear power rise from 22% to 27%, and from 5% to 10% respectively in the span of ten years.

According to the pie charts, oil was the major energy source in 1980s in the USA and it provided more than 40% of their total energy demand. Natural gases was the second most significant energy source as it provided more than one fourth of the total energy needs. Coal provided more than 20% of the energy demands for the USA in this decade while two other minor sources for energy were nuclear power and hydroelectric power and each of which provided 5% of the total energy requirement.

In the next decade, the use of nuclear power as a source of energy in the USA doubled while the use of oil decreased. Use of nuclear power for energy in the USA doubled while the use of oil decreased. Use of coal for energy increased slightly while natural gas provided almost same energy as it did in the previous decade. Hydroelectric power provided the same percentage of energy in this decade which was the only energy source which remained unchanged.

In 1980, 42% of total energy came from oil, followed by 26% from natural gas. Standing at 33%, there was a significant decline in the proportion of oil over the period of 10 years, from 1980 to 1990. Follow this trend, the percentage of natural gas also dropped slightly to 25%.
The trends for coal and nuclear power were noticeably different from those described above. While the proportion of hydroelectric power remained steady at 5%, the percentage of coal and nuclear power increase from 22% to 27% and from 5% to 10% respectively over the period in question

# data[].attributes.body
Overall, oil  accounted for the highest proportion of sources of energy whereas hydroelectric power remained the lowest in both 1980 and 1990 in USA

# data[].attributes.body
Overall, it is clear that when oil and natural gas remained as the major energy sources which the Americans depended in both years, an increased dependency is seen in  case of both coal and nuclear energy.
