Actually the belief that green energy is more expensive than fossil fuels is just that, a belief. Electricity can now be produced more cheaply with green energy than with fossil fuels and is getting cheaper as the tech continues to improve.

And green energy has nothing to do with the UN or globalists (whoever they are). Right now the biggest pushers of green energy in the US are all private companies run by people like Elon Musk (look him up).
You are right about the money aspect, but that is connected not to green energy, but to oil and cola companies which are trying to protect their turf. That is now getting harder and harder to do a the cost of green tech continues to decline.
As for aircraft, no one has claimed that commercial aircraft would be outfitted with electric motors, but I would not bet against it. Ten years ago electrically powered drones did not exist. But the engine technology has improved so dramatically that now they are everywhere.
Currently fossil fuel has one big advantage, and that is that that it is the existing tech due to the fact that it has been built up over the last 150 years. It is a phenomenon known as technological inertia. Existing tech always hangs around until the new tech shows that it is clearly superior. A few examples that illustrate this are the gradual change from steam locomotives to diesel locomotives. The change took decades. Another was the replacement of gas and oil lighting with electrical lighting. And one of the best was the introduction of the internal combustion engine. All of these new technologies took decades to replace the existing tech. Green energy with be the same. Even with full support form government green energy systems can only be introduced at a certain speed. I will say that I am quite amazed by how fast green energy is progressing, however. I thought it would take much longer before it passed fossil fuels in efficiency, but it is already there.
