If we are ever to save the planet, stop global warming, prevent soggy cornflakes, etc. etc., we must end our addiction to oil. Fine. Make it a law. Outlaw all oil-burning internal combustion engines, and require everyone to drive electric vehicles.
Where are we going to get the electricity to charge enough electric car and truck batteries for 300 million people? And power their homes and offices? And everything else that electricity is used for? Solar and wind power will never account for all this new required energy. The new power source must be clean, cheap, and "green."
Careful what you wish for.
UPDATE: If electric cars become mandated, I want Barry Obama to buy me one of these.
