First off there’s no such thing as 100% clean or renewable power. Solar panels are metals (mined with petroleum powered equipment and probably refined in China using coal) plus petroleum products (plastics etc). They’re shipped around on trucks and boats, and if they’re burnt to remove the petrolium products before extracting the metals when they’re ‘recyced’ then it’s literally burning fossil fuels.

Not only that but they’re buying RECs. The power they’re consuming could very well be 100% generated by coal, but they gave a few bucks to somebody who had solar or wind.
