Getting people to use more efficient appliances and insulating their homes should help reach these targets. We don't need to generate today levels of energy if we can drop usage by some percentage and just generate all of that with renewables.

That being said, the bill is also pushing for heat pumps to replace natural gas burning furnaces, so I'm guessing the net impact will be we need today levels of electricity generation, or maybe even a little more once we look at electrifying things that currently don't interact with the grid and consume fossil fuels directly.

And actually as I even type this, I'm remembering that electrifying cars is a big part of this that will definitely drive up electricity need way more than efficiency gains suppress demands for some use. Hopefully we can get to some of the more transformative ideas suggested about improving city planning and density together with investments in public transit so we don't end up producing way too many batteries simply to preserve a car centric transportation system.

I do think even just incentivizing consumers to buy electric everything will have a strong movement to drive more electricity generation, and renewables are the cheapest or very cost competitive options for new power generation installations. I think there are some funds in the new bill for encouraging sunsetting fossil fuel based plants early, but we likely need more of that down the line.
