As my colleagues James O’Donnell and Casey Crownhart reported, by 2028 the share of US electricity going to power data centers may triple. Both manufacturing and data centers are obviously priorities for the US writ large and the Trump administration in particular. In households, they would hit credits for rooftop solar panels and residential energy efficiency programs. Yet whether you’re talking about the ability to act or the act of providing electricity, power comes from energy. And we need efficiency.
