The two pie charts illustrate the production of electricity in the US by source in
1970 and 1984. In general, it can be said that coal was the most important
source of electrical power in both years, although nuclear power grew in
importance.
In 1970, coal-powered stations were the main source of electricity in the US,
producing 46% of electricity, and this figure increased to 55% in 1984. The
second most important source of power in 1970 was the natural gas, with
almost 25%. However, by 1984, this had declined to just 12.3%. Hydroelectric
power also declined over the same period, from 16% to less than 14%. In
contrast, nuclear energy gained in importance. It rose from just 1.4% of
production in 1970 to almost 14% in 1984, showing a ten-fold increase.
In summary, more electricity was produced from coal and nuclear energy,
while natural gas, hydroelectric power, and oil declined in importance.
