Here's the problem: we've been able to do this for 30 years now and conservatives have fought this progress tooth and nail.
Here's the real problem; We have been able to do without fossil fuels for
70 years now, and both sides of politics have fought this progress tooth and nail.
The worst offenders were the (not conservative at all) hippies and lefties of the 1960s and '70s, who were determined to prevent the use of
big technology of any kind to solve any problem.
They didn't (and still don't) care that size isn't a relevant factor. They just refuse to support anything that they don't fully understand, and refuse to learn anything discovered during or after the Industrial Revolution, which they see as an unalloyed
bad thing.
We are faced with a partisan choice between a bunch of greedy fucks who don't give a crap about the planet as long as they get rich selling coal, oil, and gas; And a bunch of hopeless dreamers who want to return to the pre-Industrial age, and don't care nor want to hear about the impossibility of supporting eight billion humans without big industrial behemoths.
Those few lefties who do begin to get an inkling of the problem immediately turn to genocide ("We can't support eight billion, and need to drastically cut population") because the idea of killing seven billion people is more palatable to them than the idea of building a few dozen, gigawatt-scale, clean power plants.
We are stuck choosing between people who refuse to see the problem, and people who refuse to implement the solution. And both groups have massive power, and an almost religious zeal in pursuit of their insane agendas.
We could have it all; But we are too fucking dumb to reach out and take it.
