There are a number of companies out there that sell 100% Renewably generated Electricity.
Wait... I'm confused... do you lay your own cable directly to the renewable plant?
Or does your supply contract come with a Maxwell's Demon electron bouncer to stop those ne'er do well non-renewable electrons entering your premises?
Pretty sure everyone gets grid power the same way; a mix of whatever power plants supply the grid at a given time.
