So you have decided to start doing your part to save energy and to help improve the environment. Yes, you can plant trees and take quicker showers but there is an even easier way. How many times do you go to Google in an average day? If it is more than twice then Blackle is for you. Blackle is a version of Google but with a black screen instead of a white one. So what is the difference? Well, it takes more energy to show a white screen then it does to show a black one. If you would like to start changing your energy usage they suggest changing your homepage from Google to Blackle. The only problem I have with it is it is a stripped down version. So if you want images and news and the rest you will have to go back to Google but if you do just basic web searches this may be for you. Read up on what it does here otherwise just give it a try.
