In a year that has witnessed strong growth of renewable generation and declines in fossil-fuel production, the new edition of the U.S. Energy Information Administration’s (EIA) Electric Power Monthly report confirms that solar and wind are the fastest growing sources of U.S. electricity.
In the month of July, solar, including distributed generation, accounted for nearly 3.5% of the nation’s total energy generation, up nearly 20% from 2.8% in July 2019. In the January-July 2020 period, solar accounted for nearly 3.4% of the country’s generation, up 22.2% from the 2019 year-to-date mark of 2.6%.
It should be noted that these figures only factor in solar PV generation. Solar thermal generation provided modest additions.
When all renewable energy sources are taken into account, clean energy made up 9.5% of all electricity generation in July, excluding hydroelectric, and 16% with hydroelectric included. On the year, non-hydro renewables provided 13% of all generation, up from 11% in 2019. Renewables with hydroelectric provided 21.2% of total electrical output, up from 19.2% a year ago.
This breakout year for renewables was underscored by the month of May, where renewable resources reached an all-time high share of the country’s electricity generation at 25.3%. These gains have been driven by the growth of wind and solar.
Hydropower is down 2% on the year, geothermal is down 2.9%, biomass is down 5.6%, and biofuels is down 14.5%. Yet as hard as some of those renewable generation sources have fallen, no fuel type has had a harder fall than coal.
Renewables have produced almost one-fifth more electricity than coal through July, sitting at 19.6%. On its own, electrical generation by coal is 27.5% lower than it was through this point last year and has accounted for just 17.8% of the nation’s total. And while not as stark as coal, renewables have generated 6.7% more electricity than nuclear power, which fell 1.7% over the first seven months of 2020.

Nice to see progress, but the energy transition is moving to slow in US. Solar PV could with out much effort cover 20 % of the total production and demand of electricity in the US. They could reach around 280GW solar installations in 2030 if they install around 20GW each year from 2020 to 2030. Hydro, wind and solar should cover more than 40% of electricity production in 2030. The last 40-60% are the hardest part. That will need much more storage capacity, and probably also are substantiel effort in preparing the grid for large amount for electricity that will be moved around from production sites from country side to big cities.
