The Power of Change: Innovation for Development and Deployment ... nationalacademies.org 5 facts
claimThe National Research Council (NRC) stated in 2012 that leveling the playing field for global corporations considering investment opportunities for renewables in the United States and other global market centers requires removing barriers to U.S. competitiveness while encouraging private-sector investment.
claimTechnologies for drastically reducing emissions, such as Carbon Capture and Storage (CCS), will remain critical even under a dominant regime of switching from coal to natural gas, given the relatively high carbon content of natural gas compared with alternative fuels like renewables and nuclear power.
claimRenewables in most areas of the United States are not yet cost-competitive and continue to require subsidies to establish a path toward eventual competitiveness.

Congressional testimony of Bob Perciasepe on advanced nuclear ... c2es.org Jun 4, 2019 4 facts
claimExtending the life of existing nuclear plants provides time to deploy more renewables, advanced nuclear technology, and carbon capture and storage before mid-century.
perspectiveThe Center for Climate and Energy Solutions (C2ES) advocates for energy policies that preserve existing nuclear power, expand renewables, promote advanced zero-emission technologies, and implement aggressive energy savings targets to reach 100 percent clean energy by mid-century.
claimMaintaining existing nuclear reactors and extending their operational life up to 80 years prevents short- and medium-term increases in emissions while allowing time to deploy renewables, energy efficiency, energy storage, advanced nuclear, and fossil fuel-fired electricity with carbon capture and storage.
perspectiveBob Perciasepe argues that the U.S. needs both nuclear and renewable energy sources, rather than renewables attempting to replace nuclear power for decades, to achieve deep decarbonization of the power sector.
