the EPA would have been strengthened and plenty of environmental executive orders would have been done. This may have helped perhaps push EVs faster than our current TL, probably push against coal and sped up the shift to natural gas at the least.
With the Ds in control of the Senate for much of the first few years, Byrd won't be of much help in reining in Coal, his conversion was years in the future
Lots of EOs means the Rs will be energized, regaining the Senate.
Greens don't like Natural Gas, it still Fossil Fuel. busting down on the recently relaxed Fracking Rules, means the NG Boom is throttled back
GM was losing money with each EV-1 Leased, which was the not inexpensive $4-500 a month, not far off from what Tesla charges today, but this was with Year 2000 Dollars, and you are leasing a GM Econo car for Mercedes money.
How is Gore going to force GM into keeping production up? at the time the EV-1 was a 100mile range car with NiMH batteries, that suck when the temps go up, and self discharge rates worse than old NiCads. Only thing they had going for them, was less hazardous materials and higher capacity
You really need to wait for Li-Ion Cells for Electric Cars. There are not enough Ed Begley Jrs around to change this in 2000 to get widespread adoption of electrics at this point.
And during all of this will have to deal with the popping of the .com economy, and Enron and the rest of Corporate shenanigans at work.
Then what Bin Ladin does, with one to all four Jets hitting their targets.
