Energy abundance is a dangerous delusion Mik. We are in Energy Descent.

Fossil fuels are behind every other energy source. The energy cost of energy has been increasing every year since the 1970s which was when we found the world's largest oil reserves. Now the US is at war over the remaining expensive to produce and protect reserves.

These are the energy reserves we need to build out the green energy future you speak of. The same goes for the depletion of the world's affordable copper. You can't have Fusion energy if you don't have the copper for all the necessary transformers, motors, inverters etc. No other material has the electro-mechanical properties of copper.
