One thing that's often overlooked in statistics like this is roof top solar because it's just not that easy to account for. In places like Australia, where double digit percentages of homes have solar and where building codes are actually being changed to require solar panels, this is a non trivial amount that is putting a lot of pressure on energy suppliers to adapt. Effectively whole states are running on solar when the sun comes out (which it does a lot over there). Whether they like it or not, demand for grid electricity drops a lot whenever these panels are producing. And of course a lot of people are installing batteries as well. That must be happening in the US as well and it must be having some impact.
