According to a review by the SUN DAY Campaign of data recently released by the U.S. Energy Information Administration (EIA), renewable energy sources (i.e., biomass, geothermal, hydropower, solar, wind) provided almost 23% of the nation's electrical generation during the first ten months of 2022.  

Output by solar alone increased by 26.23% and its share of total U.S. electrical generation year-to-date (YTD) surpassed 5.0%, providing 5.05% through the end of October. For perspective, solar's YTD share first reached 1.0% in March 2016. Since then, solar's monthly generation has increased almost six-fold. The trend seems likely to continue - in October alone, solar's output was 31.68% greater than a year earlier, a rate of growth that strongly eclipsed that of every other energy source.
