The economic fight is over power in the world.
Eu and china want to move over Green energy.
The russia and USA power Will be dominant if old oil is king Same goes for AE arab countries.
Eu and china are much more advanched in green energy then russia or USA.
Green energy is mostly solar power.
Solar panels are made from processed silicon. Which is essentially sand heated into glass. The barrier to entry for solar power may not be high. The issue behind most major nations of the world not becoming more involved in solar power likely has to do with lack of funding, skilled labor and expertise. Much of the existing technology behind patented solar based intellectual property has its origins in the united states. With production being moved to china in an effort to leverage lower labor costs.
In terms of efficiency, I think the advantage is with green energy given its potential for growth and scaling. Electric motors can reach 80%+ efficiency. While internal combustion engines are usually rated around 15% efficiency. The difference comes from fossil fuels having on average greater energy density as a fuel source.
It could be guaranteed that oil and fossil fuels would not last forever. At some point, we could be forced to abandon them or find alternatives when supply runs out. Perhaps its better to begin the transition now, rather than wait until its too late.
Nuclear energy is one of the most efficient forms of energy there is with modern nuclear technology but the climate change radicals sometimes don't consider that to be a viable option for whatever reason.
EV's aren't part of the solution for clean energy consumption because of the raw materials needed to manufacture batteries and the fact that EV's are charged through fossil fuels. EV's just give people a temporary solution to a problem they've created. These people have not even considered whether electrical grids could handle the strain that EV's would introduce either.
If they were serious, they'd adopt nuclear energy.
