Earth Hour Don't be so smug.
The flash was OK. The animation was relatively good, but I didn't find this particularly humorous. The music didn't really fit either. Now, on to political rant:
Earth hour is a joke. People turn their lights off for one hour and act smug about how much they've "helped the earth." Compared to modern electricity chugging devices like refrigerators, computers, and televisions, lights are becoming a smaller and smaller portion of US electricity usage every year. If you use florescent lights, which consume a large amount of electricity when turning on, then shutting those off for an hour had about nil effect on total power consumption. Hybrid cars don't help the earth either. The process involved in making that expensive rechargeable battery releases all kinds of toxic crap into the environment.
I did not participate in Earth Hour. However, I have had the lights off in my room for the past four hours even though it's pitch black outside, using my laptop which consumes a very small amount of electricity. So shoot me.
In conclusion, instead of participating in a minor event once per year, try to be more eco-friendly all year long. Walk if it's close enough. Turn off the lights before you leave the room. Drive in a way that uses less gasoline (Hint: Try hitting the brakes only when absolutely necessary. If there's a red light up ahead, don't drive as fast as possible to the area and then brake. Take your foot off the gas pedal and slowly approach the light. People will honk at you, but you can ignore them. By the time you reach the light, it will change to green.) Turn the thermostat to 60 in winter and 75 in summer.
tl;dr: Earth hour is for being smug. Save some electricity 24/7/365 instead.
