“Rolling electric power blackouts afflicted roughly 2 million California residents in August as a heat wave gripped the Golden State. At the center of the problem is a state policy requiring that 33 percent of California’s electricity come from renewable sources such as solar and wind power, rising to a goal of 60 percent by 2030. Yet data showed that power demand peaks just before the sun begins to go down, when overheated people turn up their air conditioning in the late afternoon. Meanwhile, the power output from California’s wind farms in August was erratic.
Until this summer, California utilities and grid operators were able to purchase extra electricity from other states. But the August heat wave stretched from Texas to Oregon, so there was little to no surplus energy available.”
“California has been bringing the hammer down on a huge source of safe, reliable, always-on, non-carbon-dioxide-emitting electricity: nuclear power. In 2013, state regulators forced the closing of the San Onofre nuclear power plant, which supplied electricity to 1.4 million households. By 2025, California regulators plan to close the Diablo Canyon nuclear power plant, which can supply electricity to 3 million households.
The problem of climate change, along with the blackouts resulting from the vagaries of wind and solar power, suggests that California should not only keep its nuclear power plants running but also build more innovative reactors designed to flexibly back up variable renewable electricity generation.”
