Renew Economy
@bascule This reminds me of a NREL report years ago saying we (US) could reach 93% renewables for power delivery for like 3T$ involving quite a few grid upgrades. That was a while ago and prices on renewables keep going down. It added the dimension of shifting wind power around at night but battery tech is really turning the corner. We just need politcal will 🙁
