I don’t use the term whataboutism in my post anywhere. So I don’t know who you are quoting.
The not serious person here is you, saying we are all going to die anyway instead of encouraging people to do anything. I had to look this up as I don’t know anything about Carter, but it turns out the panels he was installing are for hot water. They don’t generate electricity. This makes perfect sense as it took much longer than that to develop photovoltaics and get them ready for mass production. Even now modern photovoltaic panels are fairly inefficient devices.
We already have walk-able cities in much of Europe. It’s not a compete solution by itself, we still have cars. You are weirdly fixated on USA history when this is a global problem. It’s not all about the USA. Stop pretending it’s the only country that exists. India and China are the biggest polluters these days if I remember correctly, you should be focusing on them.
Edit: Carter was also aiming for 20% of energy in the US to be made renewably by 2020. That wouldn’t have been anywhere near enough to stop climate change.
I can read fine. You can’t write. Your messages so far have been full of spelling errors, are hard to understand, and you can’t even quote properly. Come on now.
You act like I should know all about this Carter person, when they were in power long before I was born, in a country I don’t even live in. It’s daft. Most people on this site either wouldn’t have been born or would have been small when Carter was talking about this stuff. That happened in the 1970s. If it isn’t absolutely clear using renewables for everything in the 1970s wouldn’t have been practical. Nuclear would have been great, but it’s mainly environmentalists that put a stop to that, as they keep trying to do now. It seems most environmentalists and climate activists even now don’t want nuclear, even though it’s the obvious choice for certain applications like data centers and AI. The most staunch anti-nuclear people have always been environmentalists. Nuclear also wouldn’t have solved any of the problems caused by cars. It doesn’t even work without large grid storage or demand management, at least not using the reactor technology available back then. Those are things we are only just figuring out now for goodness sake. It could have at least replaced coal for baseload power, which is much better than nothing.
You can’t say in one breath that the planet is already doomed, and in the next say we should make major changes. It’s a contradiction. If people believe we are really doomed they aren’t even going to try. This should be relatively straight forward to understand. So if you want people to make a change then stop saying we are already dead.
