On December 20, 1951, researchers used energy produced by Experimental Breeder Reactor-I near Arco, Idaho, to illuminate four 200-watt lightbulbs. Since then, utilities have built commercial nuclear power plants in the United States almost exclusively to generate electricity. This has worked well alongside other power generation and transmission infrastructure—large oil- and coal-fired, natural gas turbine or hydroelectric plants, and a relatively simple electrical grid designed to deliver reliable power.

Humanity is now embarking on an epic and complex energy transformation across the grid, industry, and transportation. Renewables like wind and solar are contributing an increasing share of carbon-free electricity to the grid, but that contribution is variable and hard to predict—sometimes those sources produce more electricity than the grid needs, and sometimes less.

Biden

President Biden introduced a $2 trillion American Jobs Plan on Wednesday to overhaul and upgrade the nation’s infrastructure as part of his “Build Back Better” campaign pledge. His plan is ambitious: “It is not a plan that tinkers around the edges,” Biden said. “It is a once-in-a-generation investment in America.”

According to Axios, the policy would be “the most far-reaching federal investment to date in programs that would help curb greenhouse gas emissions. But it faces serious challenges in the closely divided Congress.”

Manchin

Speaking at a U.S. Senate committee meeting this week, Sen. Joe Manchin (D., W.V.) said that continuing support for nuclear energy would be essential in meeting the country’s goals of reducing the emissions that fuel climate change, according to the Politico Pro newsletter.

Details: Manchin, who heads the U.S. Senate Energy and Natural Resources Committee, was highly critical of anyone suggesting that climate change can be addressed without nuclear energy being in the mix.

An article published by The New Yorker profiles how Heather Hoff and Kristin Zaitz went from environmentalists who were skeptical, and even distrusting, of nuclear power to advocates for the much-maligned power source.
