CdTe has EROEI of of 43:1, and rising (and of course it's recyclable, CIGS has about the same energy density as enrichened uranium over lifetime, and of course it is also fully recyclabe), while in its heyday oil had 100:1 and is now down to 25:1 in best locations, and much lower (below 10:1) in others. I wonder solar is still called 'alternative' energy. It should be called alternativeless energy. There is really no other way to keep this civilisation running.
