Turn Off Your Computer at Night
Many of us spend so much time on our computers, and check e-mail and other services so frequently, that we never turn the things off.
It may occasionally take you a few more seconds to get to work, but you'll save energy and money if you turn your computer off at the end of each day. It will also reduce wear and tear on your hardware, extending its life. According to the Department of Energy you'll save an average of $90 of electricity a year.
The agency recommends shutting off your monitor if you aren't going to use it for more than 20 minutes, and the whole system if you're not going to use it for more than two hours. (It is true that very frequent cycling of the power switch can result in added wear.)
