It's possible. But even if that part is true, the large investment might spur faster growth in electrification which might then be good enough to outweigh that initial downside.
Unintended consequences are hard.
I'm just getting a little fatigued with the fearful "don't do anything, it might make it worse" coupled with the "stop all the everything" approach to environmentalism that seems to becoming ever more dominant. I just don't think that's going to work. Doing nothing won't help, and convincing people to do without doesn't work, so ?
