Sources of renewable energy accounted for 18.49% of net domestic electrical generation during the first eight months of 2019. Small-scale solar panel installations provided nearly a third of the total electricity generation. The growth rate if distributed solar power was greater than that of any of the other sources of renewable energy.
Sources of renewable energy (biomass, geothermal, hydropower, solar panels, wind) accounted for 18.49% of net domestic electrical generation during the first eight months of 2019, according to a SUN DAY Campaign analysis of just-released data from the U.S. Energy Information Administration (EIA). A year earlier, sources of renewable energy share was 17.95%.
The latest issue of EIA’s “Electric Power Monthly” (with data through August 31, 2019) reveals that solar power and wind both showed continued growth. Solar panels, including small-scale solar-powered systems, grew 13.7% compared to the first eight months of 2018 and accounted for a bit more than 2.7% of total electrical output. Small-scale solar panel installations — which increased by 19.1% — provided nearly a third (32.6%) of total solar electricity generation. The growth rate of distributed solar power was greater than that of any other of the sources of renewable energy.
In addition, U.S. wind-generated electricity increased by 4.4%, accounting for 6.94% of all electricity generated.
Combined, wind and solar power accounted for almost a tenth (9.64%) of U.S. electrical generation through the end of August. In addition, biomass provided 1.4% (increasing by 2.5%) and geothermal contributed almost 0.4% (reflecting 3.2% growth). In total, non-hydro sources of renewable energy accounted for 11.44% of total U.S. electrical production during the first two-thirds of 2019 and grew by 6.15% compared to the same eight-month period in 2018.
Notwithstanding a 5.2% decrease in hydropower’s output, electrical generation by all renewables (including hydropower) was 1.49% higher than a year earlier. By comparison, nuclear-generated electricity declined by 0.6% while that from coal plummeted by 13.9%. However, much of the latter was replaced by natural gas which grew by 6.5%.
