green is universal

I'm watching Sunday Night Football right now and they're doing this thing saying "Green is Universal" where they are promoting conservation. They even have the lights off in the studio! They're also saying that they'll start shutting down the studio each night. Shouldn't they be doing that anyway?

Anyway, if you really want to save energy, just the the obvious things like turn off the lights when you aren't using them, buy energy saving bulbs, and don't make gratuitous use of electricity of fuel. That means you, Alissa... and David! I know that you left the lights on in the apartment over the summer. There's no other reason why the electricity would go up when 2 of the 3 people move out.
