To What Extent Are We Using Science for Sustainable Development?

[Woodwizard]

1. Tiresome blather about solar and wind?

It works and is growing, have had solar since 2014 it first system installed was 9KW it was put on my shop roof did 80 percent of our electric and paid for itself in 7 years. This year I added another 4.6KW which should make 100 percent and it runs our heat pumps for fossil free heating and cooling. Cost of components has dropped a lot in the last decade. Just stay away from solar giants like Sunrun.

If every house that has a viable space for solar power needs from central plants would be greatly reduced during peak demand.

So how does it not prove useful?

Are there other problems to be solved of course, solar and wind are a start. Especially in developing nations without much of an established grid.
