From what sources does America generate electricity?

Question

Sources mean the following: Coal; nuclear; wind; hydro; etc. Also helpful would be recent US gov't docs pertaining to these sources and the amount which the US used during a particular year, such as: Coal, 50%; nuclear, 10%; etc.

Answer 1

In 2004, US electricity production was produced from the following sources:

Coal 49.8%
Nuclear 19.8
Hydro 6.5
Oil & Gas 21.4
Other 2.5 - that includes solar and wind

The US consumes about 4 trillion kilowatt hours of electricity every year. Most of the production is domestic, but the US also buys electricity from Canada.

Answer 2

the link below is to a department of energy table that gives electrical power production by energy source for the last 50 years or so up to 2004

http://www.eia.doe.gov/emeu/aer/txt/ptb0804a.html

the table gives the electrical energies in Trillion-BTU but you can easily calculate percentages by dividing by the total for each year

it appears that in 2004, coal was the winner, with about half the U.S. electrical production coming from coal

Answer 3

nuclear provides about 20% of our electricity. and that's from fewer than 103 operational plants, which is pretty extraordinary.

Answer 4

i watched a show a couple weeks back and they said nuclear energy only provides around 3% of the energy we use.

Answer 5

wind,hydro and lighting
