The tables show electricity production by energy sources and the number of power plants in 2005 and 2015.
Overall, coal was the biggest source in 2005, but natural gas became more important in 2015. The number of coal plants went down.
In 2005, coal produced about 2,012,873 thousand megawatt hours, which was the highest. In 2015, this number fell to 1,352,398. Natural gas increased from 760,960 in 2005 to 1,333,482 in 2015. Nuclear energy went up a little. Petroleum and hydroelectric power went down slightly.
For power plants, coal plants decreased from 619 to 427. Petroleum plants also went down a little. Natural gas plants increased from 1,664 to 1,779. Nuclear plants fell slightly. Hydroelectric plants went up a little.
In conclusion, coal use went down, natural gas went up, and other sources changed only a little.
