So, we have to make some changes in the way we live.
We can decarbonize our electric grid severely in a decade or so by just building nuclear out on a large scale. Which is what France did in the 70's and China's doing now. France has one of the lowest carbon intensities of any electric grid in Europe, with some of the lowest electric rates. Only hydro heavy countries do better (and not by much on either scale.). The technology is there, it's proven, it works.
We need to develop more public transit alternatives, including more commuter and long distance rail.
Long distance is dead. It's not 1950s anymore. Short corridors might work, if they're fast enough. The NE's average speed is basically the bottom of what's workable.
It's probably finally time for a carbon tax, which may make public transportation more attractive as it raises the price of gas.
Ahhh yes, the great answer to everything - force people into modes of transport they don't want to be in because they suck. How about fixing rail transport so folks actually
want to take it?
But then we have to provide some public transportation alternatives. We have to get those Kansans thinking beyond the cabs of their trucks, and that won't happen unless viable alternatives are on the ground.
The trouble is, the answer for 'viable' isn't what most railbuffs want to see - i.e. lightweight DMUs, railbuses, mainline electrification, and knocking sense into the FRA and Class Is, and probably in the long term - nationalization of the network to achieve those goals. i.e., what everyone else figured out years ago. It's insane to think that if we bring back the network of the 50's, it'll work this time. It didn't work back in the days of DC6s and cars that could barely get out of their own way.
So, expensive as it may be, we need to start building out some public transportation alternatives before the demand is there. People have had 2 generations of jumping in their trucks and forgetting about other alternatives. We have to provide some useful alternatives so the "jump in my truck" mindset can start to change.
Decarbonize the grid and get as many as possible into electric vehicles. But that means dumping coal (which would wipe out at least one big Class I), gas for peaking (and those evil pipelines to get it everywhere - it's insane we flare off gas in one part of the US and have shortages in another), nuclear (Oooo scary!!!!), that ugly catenary that always ruins the perfect shot, and realizing that electric cars will be the answer for a lot of people. Maybe hydrogen as an aviation fuel, though that may/may not work. Storage and energy density IIRC were the big issues (gas turbines pretty much burn anything).
