Blackle is Google but with a black background. Yes, that’s it. One tiny change. But why? Well, black backgrounds use a (tiny amount) less energy than white backgrounds. Yes, it is tiny, but imagine the saving when multiplied across Google traffic – it’s currently saved nearly 100,000 Watt hours in a matter of weeks.
It’s an idea and ideas are a good thing. Ideas that contribute to energy efficiency are even better. So set Blackle as your homepage and do your bit.
