Re: Gary Wolfram’s May 12 column “Can we replace fossil fuels by 2030?”: Wolfram’s piece does not highlight the important role that our existing nuclear energy plants play in producing carbon-free energy, and how critical nuclear is to our cleaner energy future.

Nuclear energy, which contributes 63 percent of our carbon-free energy, prevents a half-billion tons of carbon emissions per year, according to a recent Brattle Group Study. In fact without existing nuclear energy facilities, carbon emissions from the electric sector would be 25 percent higher.

Despite their environmental benefits, some existing nuclear plants across the country remain at risk for premature closure, partially because they are not properly valued for their carbon-free benefits. In the absence of these existing nuclear plants, it would be very difficult to meet proposed carbon reduction goals.
