How do you charge your batteries?
How do you know the electricity you're using isn't generated by burning coal (a fossil fuel) or uranium (another non-renewable resource)?
Do you have a windmill in your back yard and can only drive after a windy day?
Do you ask your electricity provider to only route to your house electricity generated by ruining rivers (dams) or killing birds (windmills)?
Do you pretend like you're drawing from the 5% of energy from hydro plants on the grid, and everyone else is using the dirty stuff?
