Not that I am pro-suicide booths, but at least they are voluntary for individuals (well at least if they had a few safeguards against accidental usage sadly lacking from the Futurama version were it not for the comedic element). They are not as cruel as forcing millions a people to live in squalor with poor sanitation, non-potable water supplies, limited food resources, etc. because someone else decided CO2 is bad and you can't be allowed to have any fossil fuels.
Please, if you are going to insist on no fossil fuels, delay that enforcement until we actually have some viable alternatives. Any alternative that is not nuclear or future tech is not really a viable alternative. Renewables without cheap energy storage are clearly not a viable replacement technology by themselves. The time to develop LFTR on a Manhattan Project basis is negligible in terms of additional CO2 burden if you could start converting fossil fuels power plants en masse starting in 2025. Lockheed Martin hss promised fusion by 2025. LFTR is the safe bet in terms of viability; no-one that really understands the technology says any fundamental breakthroughs are needed. So do both and let ITER and other projects continue.
Give us cheap room temperature superconductors and we could cover deserts around the world with solar panels and windmills without having to store energy. Or just nano-tech solar cells that grow themselves all over our roads. I am not fussy about how it is done, but if you double the cost of electricity you are killing people in large numbers. German electricity is already 0.36 per kWh and 0.12 in the US and 0.08 in China and India. Where do you think manufacturing will grow, where are people burning lots of wood because it it deemed renewable? You and Al Gore are probably safe though, so why should you really care -- pretending to care is enough isn't it.
Not really harping on you in particular since I suspect you would going for the comedic line. But we are ruled by lots of stupid and venal politicians that are pissing on the future as well as today.
