Hold on there, they have been very explicitly doing the opposite of reducing energy costs. The administration has been aggressively trying to cancel all sorts of energy projects, even projects that have almost been completed. At the same time they've been encouraging as much data center build out as possible. Lowering supply and increasing demand is hardly going to reduce energy costs.
They have managed to significantly lower expectations for global economic growth which brings down energy costs, but that's hardly a sane way to accomplish that goal.
