Unlike her predecessor Rick Perry, the Texas Republican who famously thought the job of Energy Secretary was to be a global ambassador for American oil and gas, Jennifer Granholm came into Joe Biden’s cabinet with a clear understanding of the role. The Energy Department has jurisdiction over the nation’s energy resources—particularly its nuclear energy capabilities—but also its energy goals. And Biden has made abundantly clear, with the recently-passed infrastructure bill and his proposed Build Back Better agenda, that a greener and more energy efficient economy is a cornerstone of it’s vision. It’s up to Granholm to bring many of those goals to life.
