The solar panels and wind turbines require materials that are not available on a scale that would allow those sources of energy to ever meet our current needs, let alone future needs.
This is simply not true. I have no idea where you are getting it from.
A wind turbine is simply a bunch of fibre glass, a gear, and a generator. Fibre glass is abundant, gears just require rather commonly available metals, and the generator is often a standard electromagnetic generator. You can win a few percent extra power and possibly save on the gear by going to permanent magnets, but 5% at the margin isn't going to determine whether we can meet the energy needs of the world -- and the "rare earths" needed for permanent magnets are not actually very rare.
Solar cells are made from a myriad of materials. Some of those will scale almost unlimited, some likely won't.
However, your views luckily do not matter. Wind power is now cost competitive in South America without subsidies, even if fossil fuels do not have to pay for any of the damage they cause. In just a few years that will be true in much larger parts of the world. Simple economics will kill off coal-fired power plants.
