A friend, who leans Ron Paul libertarian, was recently trying to convince me that anthropogenic global warming is largely a myth.

I'd like to ask a relatively simple question – what would happen if we switched of traffic lights when we didn't really need them? I'd like to know from an environmental aspect what effect turning off the nations traffic lights would have towards saving electricity and reducing emissions.
