> Also solar panels do not work when the power grid goes down. People who own them were not told that little secret. Sure they do if your inverters support it. It's just that most people's systems aren't set up that way. > I agree that electric motors are more efficient than petrol motors. But considering how the electricity is generated needs to considered. If your power is hydroelectric, then great! That's as good as it gets. It's even better cost-wise when you have solar. You're literally charging for free since that power is a sunk cost.
