U.S. renewables generation mix to double by 2050
The U.S. Energy Information Administration (EIA) announced on Feb. 8 that it expects the share of renewables in the U.S. electricity generation mix to increase from 21% in 2020 to 42% in 2050. Wind and solar generation are responsible for most of that growth.
According to its Annual Energy Outlook 2021 report, EIA expects the renewable share to increase as nuclear and coal-fired generation decrease and the natural gas-fired generation share remains relatively constant. By 2030, renewables will collectively surpass natural gas to be the predominant source of generation in the United States. Solar electric generation (which includes PV and thermal technologies and both small-scale and utility-scale installations) will surpass wind energy by 2040 as the largest U.S. source of renewable generation.
The report states that the natural gas share of the U.S. electricity generation mix is expected to remain at about one-third of total generation from 2020 to 2050. The natural gas share of generation will remain stable even though natural gas prices will remain low (at or lower than $3.50 per million British thermal units, in real dollars) for most of the projection period. This stability occurs despite significant coal and nuclear generating unit retirements resulting from market competition as regulatory and market factors induce more renewable electricity generation.
The share of natural gas-fired generation in the United States will remain relatively constant through 2050 and the contribution from the coal and nuclear fleets will drop by half. Through 2050, the share of electricity generation from renewables will double. Wind will be responsible for most of the growth in renewable generation from 2020 through 2024, accounting for two-thirds of the increase in that period.
After the PTC for wind phases out at the end of 2024, solar generation will account for almost 80% of the increase in renewable generation through 2050. EIA assumes that utility-scale (and commercial) solar PV facilities will receive a 30% ITC through 2023, which will then be reduced to 10% beginning in 2024 and lasts through 2050. Residential solar PV will also receive a 30% ITC through 2023, which will expire in 2024.
