A common argument against electric/hydro cars is that the battery has to be manufactured and charged, or the hydrogen produced, which itself uses electricity. However, the factory which manufactures the battery or produces the hydrogen can be powered by nuclear energy which is (apparrently) cleaner than fuel-burning power stations - assuming that the waste product is disposed of safely. Also, mains power to private properties can be produced using the same means, which means batteries can be charged more cleanly. Compare this with fuel-burning cars, which are impossible to fuel cleanly since they use a combustion engine.
