EIA projects renewables to provide 10 percent of electricity generation in 2018 in the USA

The US Energy Information Administration (EIA) projects that total solar electricity generation will increase from an estimated average of 209,000 megawatt hours per day (MWh/d) in 2017 to 240,000 MWh/d in 2018 and to 287,000 MWh/d in 2019. Wind generated an estimated 691,000 MWh/d in 2017. EIA projects that generation from wind will rise to an average of 765,000 MWh/d in 2019. Nonhydropower renewables provided slightly less than 10 percent of electricity generation in 2017 and is expected to provide about 10 percent in both 2018 and 2019. The generation share of hydropower was almost 8 percent in 2017 and is forecast to be about 7 percent in both 2018 and 2019.
EIA expects the share of US total utility-scale electricity generation from natural gas-fired power plants to rise from 32 percent in 2017 to 34 percent in 2019. The forecast generation share from coal in 2018 averages 30 percent, about the same as in 2017, but then falls to 29 percent in 2019. The nuclear share of generation was 20 percent in 2017 and is forecast to average 20 percent in 2018 and 19 percent in 2019.
Separately, EIA released its »Annual Energy Outlook 2018« (AEO2018). According to this figures, almost all of new electricity generation capacity is fueled by natural gas and renewables after 2022 in the reference case. This is the result of remaining natural gas prices and the continued decline in the cost of renewables, especially solar photovoltaic.
Renewables are the world’s fastest-growing energy source, with consumption increasing by an average 2.3 percent per year between 2015 and 2040. Wind and solar generation leads the growth in renewables generation throughout the projection, accounting for 64 percent of the total electric generation growth in the reference case through 2050. Renewable generation is projected to increase 139 percent through the end of the projection period, reaching 1,650 billion kilowatt-hours (BkWh) by 2050. The increase in wind and solar generation leads the growth in renewable generation through the projection period, accounting for nearly 900 BkWh (94 percent) of the total growth in the reference case. Electricity generation from solar PV facilities in all sectors is projected to reach 14 percent of total electricity generation by 2050 in the reference case, with 53 percent of the total from utility-scale systems and 47 percent from small-scale systems.
