Report: U.S. Renewables Overtake Nuclear Power

The latest issue of the U.S. Energy Information Administration’s (EIA) Electric Power Monthly (with data through April 30) reveals that renewable energy sources – including solar, wind, geothermal and hydropower – are now providing a greater share of the nation’s electrical generation than nuclear power, according to a new analysis from nonprofit SUN DAY Campaign.

For the first third of this year, renewables and nuclear power have been running neck-in-neck, with renewables providing 20.20% of U.S. net electrical generation during the four-month period (January-April) compared to 20.75% for nuclear power. But SUN DAY says that in March and April, renewables surpassed nuclear power for the first time and have taken a growing lead: 21.60% (renewables) vs. 20.34% (nuclear) in March, and 22.98% (renewables) vs. 19.19% (nuclear) in April.

Although renewables and nuclear are each likely to continue to provide roughly one-fifth of the nation’s electricity generation in the near-term, SUN DAY claims the trend line clearly favors a rapidly expanding market share by renewables: Electrical output by renewables during the first third of 2017 compared to the same period in 2016 has increased by 12.1%, whereas nuclear output has dropped by 2.9%.

In fact, the nonprofit says nuclear capacity has declined over the last four years – a trend which is projected to continue, regardless of planned new reactor startups. On the other hand, almost all renewable energy sources are experiencing strong growth rates. Comparing the first four months of 2017 to the same period in 2016, solar has grown by 37.9%, wind by 14.2%, hydropower by 9.5% and geothermal by 5.3%. Biomass has remained essentially unchanged – slipping by just 0.3%.

In recent years, the strong growth rates of both solar and wind have resulted in new records being set virtually every month. For the second month in a row, solar and wind combined provided more than 10% of the nation’s electrical generation. In March, those sources provided 10.04% of the nation’s electrical generation. That record was eclipsed in April, when solar and wind reached nearly 11% (10.92%) of total generation. And, for the first time, wind and solar combined have provided more electricity year-to-date (113,971 thousand megawatt-hours [TMWh]) than has hydropower (111,750 TMWh), according to SUN DAY.

In April, solar alone reached another milestone, providing more than 2% (2.33%) of the nation’s electrical supply. Consequently, solar has now moved into third place among renewable sources – behind hydropower and wind, but ahead of biomass and geothermal. In April, utility-scale plus small-scale solar provided 20,928 TMWh compared to 20,509 TMWh from biomass and 5,945 TMWh from geothermal, according to SUN DAY.
