Environmental and Public Health Benefits of Solar Power


Solar power could deliver $400 billion in environmental and public health benefits throughout the United States by 2050, according to a study from the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and National Renewable Energy Laboratory (NREL).

“We find that a U.S. electric system in which solar plays a major role—supplying 14% of demand in 2030, and 27% in 2050—would result in enduring environmental and health benefits. Moreover, we find that the existing fleet of solar plants is already offering a down-payment towards those benefits, and that there are sizable regional differences in the benefits,” said Ryan Wiser of Berkeley Lab’s Energy Technologies Area.

The total monetary value of the greenhouse-gas and air pollution benefits of the high-penetration solar scenario exceeds $400 billion in present-value terms under central assumptions. Focusing on the existing end-of-2014 fleet of solar power projects, recent annual benefits equal more than $1.5 billion under central assumptions.

The report, The Environmental and Public Health Benefits of Achieving High Penetrations of Solar Energy in the United States, is part of a series of papers published as part of the U.S. Department of Energy’s On the Path to SunShot study. The DOE launched the SunShot Initiative in 2011, with the goal of driving down the cost of solar energy so that it was cost-competitive with other forms of electricity by the end of the decade. The new reports take stock of the progress already made, and highlight various barriers and opportunities that remain to achieving SunShot-level cost reductions.
