Sure we have lot's of nice ways to generate renewable power, but it is very expensive to store it once generated. Without adequate storage capacity, renewable sources are not practical.
What good is a solar panel at night? What good is a wind turbine when there's no wind? If you could store several days worth of power in your home for a reasonable price then you could easily go 100% renewable. Batteries, fuel cells, flywheels, water towers or compressed air tanks - none is a good solution yet...
I leave my water heater on. It's very well insulated. You don't need to heat the water in a thermos to keep it hot for half a day, do you?
