I was busy today so I didn't see it earlier (and feel free to move the climate discussion to that thread if you want), but the US has the power to compel other countries to reduce their emissions. Obviously that hasn't been done for the past 3 years, but don't surprised if next year, the US and other OECD countries start stricter requirements on who they trade with and tax imports from China and elsewhere based on their emissions.
As I've said before, but wind and solar will continue to grow. Hydro has its problems, as you're all discussing, as does nuclear, but as long as they're around, they might as well get used. Coal will gone before long (Virginia just passed its 100% RPS for 2050 and banned coal generation by 2024) by which point investment in gas generation will have peaked (the current oil & gas market collapse isn't an isolated problem and will have long-term consequences, too). Hydrogen will gradually displace it for all its purposes (heating, generation, etc.) as electrolysis becomes economical.... This will all continue to happen faster in Europe and Australia, to be sure, but this transition is inevitable so there's not much point to slowing it down.
