The US Can Get To 100% Clean Power Without New Nuclear
There is a widespread view that nuclear energy is necessary for decarbonizing the electricity sector in the United States. It is expressed not only by the nuclear industry, but also by scholars and policy-makers like former Energy Secretary Steven Chu, a Nobel Prize-winning physicist who recently said that the choices we have “…when the wind doesn’t blow and the sun doesn’t shine” are “fossil fuel or nuclear.” I disagree.
Wind and solar are much cheaper than new nuclear plants even when storage is added. The National Renewable Energy Laboratory estimated the cost of unsubsidized utility-scale solar plus battery storage in 2021 was $77 per megawatt-hour — about half the cost of new nuclear as estimated by the Wall Street firm Lazard. (An average New York State household uses a megawatt-hour in about seven weeks.)
