The fastest growing energy sources during this period were wind and solar, according to analysis by renewables advocacy group the Sun Day Campaign.
Wind generated 11.1% more electricity (144.8GWh) than it did in the same period one year earlier , and accounted for 9.4% of the United States' total generation between January and May — up 1.4 percentage points from the first five months of 2019.
According to “uåX˜äŠÊ˜·³Ç Intelligence, the research and data division of “uåX˜äŠÊ˜·³Ç, the US’ wind power fleet reached nearly 109.3GW by the end of May 2020 — an increase of 11.7% year on year.
Meanwhile, solar generated 23.1% more electricity in the first five months of 2020 (50.6GWh) than it did in the same period one year earlier, and accounted for 3.3% of the US’ total electricity generation in this time — up half a percentage point from January-May 2019.
Combined, renewable energy sources — also including hydropower, biomass and geothermal — generated 331.2GWh in the first five months of the year. This is more than both coal (258.9GWh, down 33.9% year on year) and nuclear (327.6GWh, down 1%).
However, natural gas still produced the most electricity in the first five months of the year — 606.9GWh, up 7.9% year on year.
The Sun Day Campaign’s executive director Kenneth Bossong said: “With each passing month, it is becoming ever more probable that renewables will outpace both this year and then begin closing the gap with natural gas."
