Earth Hour, if you haven't seen the commercials, is 8:00 PM - 9:00 PM on March 29th. During that period, you are encouraged to turn off your lights. And all the Canadian McDonald's restaurants will be doing so, as well.
My first question when I saw the ad on TV was: does that mean I need to turn off everything, or just the lights? Apparently McDonald's is going with the "just the lights" idea, and will be turning off their signs and lighted roof beams.
Estimated savings: 10,000 kWh in electricity, the same amount the average Canadian household uses in a year.
Hmmm. Let's turn out the lights of all the McDonald's around the world, every night, and we'll really see an impact. But just imagine: think of all the closed lit-up places you pass by every night, and think how much energy is wasted. It's sobering.
