Alternatives to Solar and Wind

i have a new argument that i'm really excited about t try it out onust. But this is the one argument ihave come up with since fossil future at is not fully in fossil future. So when i revise it, this will be added. It's basically that all these studies that claim to be able to rapidly replace fossil fuels with solar wind have three things in common - they are claiming our low cost, but that we know are of indeterminate high cost. And so, you know, sight unseen, these plans are all total crackpot. I like just the specificity of what's going wrong in all of these claims.
