There are other sources of energy. Ones that will provide more energy for the same investment.

And where does this investment come from? Who's going to just donate trillions upon trillions of dollars to Cambodia and Laos and Myanmar and Afghanistan and the thirty-three undeveloped African nations?

Right now we've got highly developed countries like France bragging that they're 20% renewable. That's as far as we've gotten since the late '60s, when we noticed the problem. Fifty years later, no country with a population over 25 million has achieved more than 20%.

With massive political will, and a population receptive to austerity measures (or a flat-out Stalinist push, human rights be damned), perhaps a heavily populated nation could achieve 100% for itself.

But achieve it for the billions and billions of people living in societies that are still developing? It's just not going to happen. Not without a massive shift in how we govern ourselves, on the order of eliminating countries entirely and establishing a world government.

Same source of revenue as the coal plants would have.

Government funds or world bank loans.

Additionally, a little bit of UN donations Fund-of-Funds Investing in Clean Energy Infrastructure in Developing Countries

Right now we've got highly developed countries like France bragging that they're 20% renewable.

26%, if we're talking electricity prodcution. But they're 63% nuclear, which is 89% zero emissions from fuel: https://www.statista.com/statistics/1263322/electrical-production-by-sector-france/

Fifty years later, no country with a population over 25 million has achieved more than 20%.

Kenya is mostly renewable for electricity production. They've got 53 million people.

Brazil is also mostly renewable for electricity. They've got 214 million. Even overall Brazil is about 45% renewable.

Even 50 years after we discovered that global warming is going to be a problem, global oil consumption is still on an ever-upward trend, rising every year with no sign of even leveling off, let alone falling:

British Petroleum has estimated that all oil reserves will be drained in about 40 years, at which point it won't be economical to extract anymore.

So, basically, in order to avoid the endpoint of "we took all the ancient carbon out of the ground and put it in the air," we'd need to take this five-decade upward trend and not only flatten it out, not only cause it to start decreasing, but actually plunge it into the ground and make it hit zero.

And we'd need to do it all within less than forty years. Probably more like ten. And then the temperature would still continue to rise for decades before finally starting to level off.

It's just completely infeasible, any way you look at it. It's a pipe dream. There isn't time. Politicians don't want to admit that, because it's their job to pretend they can fix any problem. But this one is well beyond their capabilities.

Absent a complete game-changer like a global nuclear war or a pandemic on the level of the bubonic plague, we as a species are going to finish emptying the Earth of its carbon reserves long before we can even turn Spain into a green paradise, let alone South Asia and its two billion inhabitants.

I agree that oil consumption is still growing, and CO2 emissions are still growing, and there's 40 or 50 years of proven reserves left for oil.

So, basically, in order to avoid the endpoint of "we took all the ancient carbon out of the ground and put it in the air," we'd need to take this five-decade upward trend and not only flatten it out, not only cause it to start decreasing, but actually plunge it into the ground and make it hit zero.

Don't forget coal. That's easier and more important to leave in the ground.

And we'd need to do it all within less than forty years. Probably more like ten. And then the temperature would still continue to rise for decades before finally starting to level off.

yes.

It's just completely infeasible, any way you look at it. It's a pipe dream. There isn't time.

Everything we do helps a little bit. Burning all the proven oil reserves in 50 years will peak CO2 at a slightly lower level than doing it in 20, because of processes that sequester CO2. OF course 500,000 years would be much better, and the difference would be significant.
