The main source of electricity in the USA comes from
natural gas, which generates about
40% of the country's electricity. Other significant sources include
coal (around
20%),
nuclear power (about
20%), and
renewable sources like wind, solar, and hydropower, which together contribute around
20% as well.
Over the past few years, the share of
renewables like wind and solar has been growing rapidly, while the share of
coal has been declining due to environmental concerns and the availability of cheaper, cleaner energy sources like natural gas.
The exact breakdown can vary slightly depending on factors like weather, economic conditions, and technological advancements, but natural gas is currently the largest single source of electricity in the U.S.
