California climate goals easier to reach with Diablo Canyon, says study

Extending the operational life of California’s Diablo Canyon nuclear power plant beyond 2025—its scheduled year of retirement—would help the state meet its climate goals more quickly, more reliably, and more cheaply than allowing the facility to close, a new study has found.

According to Retaining Diablo Canyon: Economic, Carbon, and Reliability Implications, keeping the plant on line could not only substantially reduce California’s emissions, natural gas use, and electric power costs, but also help avoid blackouts.

“Being real means that the renewable revolution requires nuclear power”: Bulletin of the Atomic Scientists op-ed

In a recent opinion piece in the Bulletin of the Atomic Scientists, mathematician and economist Michael Edesess writes that “The goal of net zero greenhouse gas emissions by 2050 [appears] unrealistic.” Edesess, a research associate of the EDHEC-Risk Institute, adds, “We must, in the final analysis, be realistic. Being real means that the renewable revolution requires nuclear power.”

Then: Edesess traces the history of interest in renewable energy sources to the 1970s when, he notes, climate change was not even part of the calculations. Back then, the thought was, “We only needed to reduce the oil we imported from the Middle East. Solar and wind could do that if only we could drive the cost down.” However, “For nuclear, driving the cost down was not the objective. The objective was to make nuclear power ever safer and safer. This drove nuclear power’s cost up.”
