Is 100% renewable energy the best goal to cut power sector emissions?

March 26, 2017 by Ronjoy Bezbarua

(Source: Utility Drive) A research review, commissioned by the Energy Innovation Reform Project (EIRP), examines the best route to “deep decarbonization” of the power sector — nearly zero greenhouse gas emissions by mid-century. It argues 100% renewables is not the best way to get there. The review assumes that an 80% to 100% cut in carbon emissions from the electric utility sector is necessary to limit global climate change to 2°C this century. It argues the literature shows eliminating the last 10% to 30% of emissions needed for deep decarbonization is more cost-effective with a diverse energy mix. That mix includes “a lot more wind and solar, more energy storage and demand response, but also what we call ‘dispatchable base resources,’” Jenkins said, including nuclear power, fossil fuel generation with carbon capture and storage (CCS), biomass, hydropower, and geothermal energy.
