What do we use to make the electricity for the electric tractor? What raw materials do we need in order to make all of the solar panels that would provide electricity for the entire world?

By the way, I see the value in electric vehicles, but we need to recognize that the electricity has to come from somewhere and that all these new vehicles and batteries require raw materials that have to come from somewhere.

Yes, we do have plenty of raw materials to make electricity for the whole world. For instance, over the lifetime of a solar panel, the amount of silicon needed to generate 1kWh of electricity is approximately 1/1000th that of the amount of coal, plus the silicon isn't burned up (but can be recycled). https://www.freeingenergy.com/do-we-have-enough-materials-to...

So in fact, it requires a whole lot less raw materials (even when you include the other materials needed in a solar panel and all the processing required) to provide human civilization with solar electricity (even with storage) than with coal.
