You should write at least 150 words.
The given pie charts represent data on energy sources of the USA for the decades 1980s and 1990s. As is observed from the given information, oil was the main energy source for the USA in 1980s but later in 1990s the use of coal and nuclear power as sources of energy increased.
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 short, the USA decreased the usages of oil as source of their energy while they increased the use of nuclear power for generating energy supply they need.
