Blackle:

Instead of Google we can use www.blackle.com. It’s powered by Google.
Blackle is a search engine like Google.
Blackle saves energy because the screen is predominantly black.
There is value in the concept because even if the energy savings are small, they all add up. Every time we load our web browser reminds us that we need to keep taking small steps to save energy.

I would like to encourage you to set Blackle as your home page. This way, every time you load your Internet browser you will save a little bit of energy. It’s an energy saving initiative.
