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. |
