Last year I brought this to TPU's attention and I feel it's a worthy cause. Basically you can help support a world wide effort to help with global warming. If you take the time to read more about it, you really can help make a difference. Official website it www.earthhour.org and you can learn more about this project. All you have to do is power down your lights for one hour for one day and be apart of the cause. You can take the initiative to power down your TV, Radio, and even your computer if you like(maybe just run the laptop on battery power for that hour). It's only one hour to help with a world wide cause, think about it.
