Here is Day 5 tip for Earth Day:
Plug your electronics into a power strip and turn them off when you are not using them. When your TV and other electronics are in standby they are drawing about 10% of the power they normally use. Not only will this help the environment it will help your electric bill.
I am still working on this at my house because we do not like resetting all the clocks all the time but my work computer is always shut off and the power strip off when I am not using it. If the battery on my cell phone or computer need to be charged before I go out in the field I make sure that I charge them during off peak hours so that I am using cheaper electricity.
