Renewable Energy Sources: Taking Over Coal and Nuclear Power


May 10, 2023

According to the data released by the U.S. Energy Information Administration (EIA), renewable energy sources played a significant role in providing electricity to the United States in 2022. Clean energy was a major contributor to the United States' electricity supply in 2022, making up almost 23% of the nation's electrical generation.The EIA's "Electric Power Monthly" report revealed that green energy sources increased their electrical output by 12.4% in 2022, while the overall electrical generation grew by only 3.5%.

Renewable Energy

Renewable energy sources continued to gain ground in the United States in 2022, providing 22.6% of the total electrical generation, up from 20.8% in the previous year, surpassing the earlier prediction of 22% made by the EIA. Solar power maintained its position as the fastest-growing clean energy source, with a remarkable 24% increase in output, accounting for 4.7% of the total U.S. electrical generation in 2022, up from nearly 4% in the previous year.Wind power also made significant gains in 2022, growing by almost 15% and accounting for over 10% of the total U.S. electrical generation, showing the growing importance of wind energy in the renewable energy mix. The electrical output from geothermal sources and wood and wood-derived fuels increased by 6.4% and 0.3%, respectively. However, the generation by "other biomass" decreased by approximately 5%. Hydropower also saw a 4.1% increase in generation, accounting for around 6% of the total electrical generation.

Traditional Sources

Green energy sources demonstrated a remarkable growth rate in 2022, surpassing coal and nuclear power generation by significant margins. According to data released by the U.S. Energy Information Administration (EIA), renewable energy sources outperformed coal power generation by 17.2% and nuclear power generation by 25.9%.However, despite the impressive growth of clean energy sources, natural gas remained the dominant source of electricity generation in the country. Accounting for over 39% of total generation, natural gas continued to hold the largest share of the energy market in the United States. While natural gas is a cleaner alternative to coal, it is still a fossil fuel and has a significant environmental impact. The continued reliance on natural gas highlights the need for continued investment in renewable energy sources to meet energy needs in a more sustainable manner.


The increasing role of renewable energy in the United States' electricity mix is a promising development toward a greener and more sustainable energy future. The impressive growth of solar and wind power, along with other green sources, is a clear indication that the transition away from traditional fossil fuels is well underway.However, there is still a long way to go, as natural gas remains the dominant source of electricity generation in the U.S. Overall, with renewables on track to reach one-quarter of electrical generation in 2023 and one-seventh of total domestic energy production, the renewable energy sector will continue to thrive in the years to come.
