“There is simply no way to realistically to ramp-up all that electricity unless nuclear power (which currently produces 20% of electricity), is built out as well,” William Murray, manager of the energy policy team at R Street Institute, tells InsideSources. “Nor is battery storage technology mature enough yet to work in tandem with wind and natural gas to balance the grid. In 10 years it will be, but not now.”

Murray sees carbon capture as “a good idea whose time has come.” Carbon capture technology would allow the U.S. to continue to use conventional generation sources while also decreasing overall emissions. Supporters of carbon capture see it as a bridge technology, helping to keep the lights on while less expensive renewable generation methods are developed.
