美国电力来源与可再生能源构成US electricity sources and renewable composition in 2021

The two pie charts give information about electricity production in the United States in 2021. The first shows the various energy sources that were used to produce electricity and the second gives more specific detail about the renewable sources. Overall, it can be seen that natural gas was by far the main source of electricity production and that, of the renewable sources, wind was the most important. Looking at the total electricity production, natural gas was the main source of energy used, contributing more than a third of the total, with coal, renewables, and nuclear each adding another fifth. Together, these made up 99% of all the electricity in the U.S., with the remaining one percent listed as having come from other sources. In terms of renewable energy, almost half of this was wind power. In fact, that contributed nearly twice as much as the next biggest contributor, hydropower, which provided a little more than a quarter of all renewable energy. Solar was next, while biomass and geothermal energy contributed relatively little.
