Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

You are so right. We could get energy literally out of thin air, but we're banning it because oil isn't making enough money.
That's rather simplistic. Nothing has the energy density of a gallon of gas. That fact powered the Industrial Revolution and that's how we're chatting now.
Even if we ignore the environment, we've got to slash fossil fuel use. Once it's gone, it's gone forever, and we're still gonna need it.
For example, solar isn't powering aviation anytime soon. Imagine a 747 or F35 running on batteries. LOL, no. Don't think anyone is making battery powered combines or harvesters either. Stuff like that.
I understand your argument, but I refute your assertions with the following pieces of evidence that I hope you will consider.
Purified Uranium has 100 000 times the energy density of gasoline. Unless you time travelled from Industrial revolution era, not sure where you got "nothing":

Not saying nuclear has no downsides, but what is economical vs. what is most energy dense are two separate discussions you are trying to simplify into one. Wind is not energy dense but has been economical which is where my original argument came from. It is a competitor to oil that is being forced out.
Electric vehicles are finding their niche in lighter duty farm, construction, landscaping jobs. The article below says the current technology is suitable for under 100hp. In 20 years it may be possible to improve it to a level that it can compare or exceed performance against traditional motor models.

Just last year, the first commercial training flight on an all-electric plane took off in Canada! It wouldn't be inconceivable to charge that using solar. And for the same reason you don't have to jump right to electrifying a 747, having more electric aircraft would be useful in quickly hopping between islands or remote settlements, while reducing emissions and need to transport fossil fuels as much. Newer or different battery tech may come in due time, but if we ignore it just because it can't fully switch immediately, we hinder the progress we are making today. Before an electric jumbo jet or fighter jet, we'll get a commuter jet. Before the commuter jet we'll get a 10 seater twin prop. Before the twin prop we have the two seater single prop.<-- We are here.
