Energy density. You need large amounts of energy throughout the mining and refining process. Digging, grinding, washing, refining, transporting - all done with petrol and gas. The energy density of solar & wind is just not there.

1. Most mining operations today are open mines. 2. Petrol is burned in ICE digging and grinding machines. 3. If you want to mine in the desert you also need large amounts of water in order to wash the ores. Just look at what's happening in Chile [1].
