What point are you arguing? I asked about energy amounts and you bring up rare earth metals.

Yes. I agreed that finite resource materials are required.

I suppose what your definition of "green" is required. I'm thinking of carbon emissions resulting in climate change.

My point is it takes 7x as much energy/resources to produce renewable tech that has a shelf life of 10 years. How is that going to achieve cooling the planet if everything we use now takes 7x the resources and every middle class person wants it?

7x what we emit now is not better.
