1. The benefit of electric powered stuff (bikes, ranges, etc.) is that as generation of electricity becomes less carbon intense, all electric devices become less carbon intense. (Eg replacing the black-spewing plant in the picture with nuclear.) Hydrocarbon-powered devices have the same initial efficiency for their lifespans. (I’m not advocating - I recently installed a gas range - but I understand the potential upside to electric.)
2. As mikephillips mentioned, utility companies that sell “green” electricity are using this to make profits. Our town proudly says we use 100% renewable. The reality is, electricity generation in our state is about 25% renewable. Electrons are electrons, and the ones coming out of my outlet are not necessarily the same ones made by a solar panel in the night. So as long as less than 25% off consumers agree to pay the premium for renewables, the utility companies don’t change a thing - but pocket the up-charge.
