Solar and wind, as they are being deployed, aren't an answer. The other day I drove by a place in southern Maine I used to hunt. Its now a solar farm. Almost a full square mile of forest is now just panels. How's that good for the environment? The environment is gone. If we put the panels over existing buildings, thats one thing, but turning the last of our natural world into biological deserts? Not a good idea. I've heard the stat that it would only take 10,000 square miles (about the size of the entire state of Mass) to power the whole US but I'd bet money its BS. Maybe that's after there are panels already on every roof top and assuming no panels breaks down and operate at 100% efficiency all the time and the estimates are based on power consumption rates from 5 or ten years ago rather than good projections for 50 years or 100 years in the future. Wind isn't any better.
The only way out of the climate change/energy issue is to buck up and address the real issue, population increase. Its not that we consume too much or pollute too much, its that there's to many of us doing it. And the only way to stop that is to find a way to create an economic system that isn't dependent upon population expansion. Anyone who can't see that knows nothing of how the world works. Every animal population in nature since the dawn of time that booms, eventually has a corresponding crash from starvation and disease. We won't be any different. There are 7.9 billion people on earth and at current growth rates of .88% that means there will be double, 15.8 billion people on the planet in 80 years from now. And that's a VERY conservative estimate because in my life time, 1970 to 2023, the global population has more than doubled in just 53 years and global growth hasn't fallen bellow 1% until just four years ago. For most of modern history its been over two percent.
Solar and Wind are just putting Band-Aids on gangrene. If the idea is to find a way to supply power and food to everyone and not cause irreversible environmental damage in the process, the only realistic answer is reduce the number of people. In recent years China has reversed their one child policy to three children. That doesn't bode well for the future of the planet.
