I agree we cant get off it overnight, but humans have no choice but to try.
I find this logic absurd knowing that most of our species history our species survived without combustion engines.
You can argue "will we", that is a better argument. But there are lots of things in the past humans thought impossible that we take for granted every day now.
We are not talking about quitting smoking - where you can just cut back a bit - and eventually you can do without.....
To maintain the population level at the current consumption levels - you need a certain level of input energy to do it. Without fossilized hydrocarbons or a serious investment in nuclear (and that's a pollution nightmare for hundreds of generations) we are fucked.
You are a moron if you think rooftop solar and a few windmills is going to do the job.
You simply do not understand the scale of the problem - so you just assume somebody will find "the answer".
You are mistaken. It's true that roof-top solar won't do it but solar farms along with wind turbines and some nuclear and hydro will. It will take time - hence the generally accepted timetable of 2050 as a realistic goal.
I would have agreed with you just 10 years ago but we have reached the point where photo-voltaic panels are now the most economical way to produce power. It wasn't long ago when they were the least economical way to do it.
Then there is fusion. We can't afford to count on that holy grail but if it comes, energy production ceases to become an issue. We will be in a post-scarcity society.
I don't want to be blindly optimistic but I think it goes without saying that the prospect of extinction tends to light a fire under one's ass. We'll get it done.
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
