How do you combat global warming when the rare metals needed for Green technologies are all running out?
Like gallium for solar panels, and platinum for electric car fuel cells, which may run out in less than 20 years, etc.

Within 20 years, large amounts of oil will be hard to come by and very expensive. Most people are saying that EV and hydrogen fuel cell technology will replace our gasoline engines in are cars, but, what about Semi-Trucks? They are much more important to our current society than personal transportation.
Too me, it seems you would need MASSIVE batteries to pull trailers, not counting refrigeration. I don’t know if fuel cells could produce the power needed, but you would also need very large amounts of compressed hydrogen.
What do you guys think?

Nuclear power would be very effective, but there’s always evil people who would harvest the materials for bombs. I heard fuel cells were very efficient and effective. What’s your opinion?
