A House Oversight and Accountability subcommittee hearing Tuesday examined threats to the security and reliability of the U.S. electricity grid, which can lead to more blackouts. While reliability assessments regularly find that increased reliance on wind and solar, increased demand from electrification, an underbuilt electrical delivery network, and rapid retirements of on-demand generators are creating an increased risk of blackouts, Rep. Cori Bush, D-Mo., ranking member of the subcommittee, instead blamed other sources of the problem, namely, white supremacy. She also threw in "climate change" for good measure.
