Electricity era from hoary fuels declined in 2017 as renewable era rose

According to EIA’s Electric Power Monthly, sum U.S. net electricity era fell somewhat (down 1.5%) in 2017, reflecting reduce electricity demand. Natural gas and spark era fell by 7.7% and 2.5% from 2016, respectively, as era from several renewable fuels, quite hydro, wind, and solar, augmenting from 2016 levels.

Although healthy gas continued to be most-used fuel for electricity era for a third uninterrupted year, healthy gas-fired electricity era fell by 105 billion kilowatthours in 2017, a largest annual decrease on record. Coal-fired electricity era also fell, though to a obtuse extent, imprinting a initial year given 2008 that both healthy gas- and coal-fired electricity era fell in a same year.

Coal-fired era accounted for some-more than half of a electric ability late in 2017, with 6.3 gigawatts (GW) of a 11.2 GW total. For a initial year in at slightest a decade, no new coal-fired generators were added.

About 4.0 GW of healthy gas-fired ability was late in 2017—most was steam turbine units. However, some-more healthy gas ability was combined than retired, widening healthy gas’s lead as the largest source of generating capacity in a United States. About 9.3 GW of new healthy gas-fired generating ability came online during 2017, 8.2 GW of that were combined-cycle units.

Electricity from renewable sources, generally breeze and solar, continued to boost in 2017. Wind done adult 6.3% of sum net generation, and utility-scale solar done adult 1.3%—record shares for both fuels. In partial as a outcome of record flood in California, hydroelectricity augmenting in 2017, accounting for 7.5% of sum net generation. EIA’s latest Short-Term Energy Outlook expects hydro to continue to surpass breeze in 2018, but wind is projected to turn a accepted renewable electricity era source in 2019.

Nearly 6.3 GW of breeze turbines and 4.7 GW of utility-scale solar photovoltaic systems were added in 2017. For any technology, about a third of a year’s ability additions came online in a final month of a year; these Dec additions had small outcome on 2017 annual era values. Another 3.5 GW of small-scale solar ability came online in 2017, augmenting sum small-scale solar ability to 16.2 GW and leading biomass capacity, that finished 2017 during 14.2 GW.
