Google is the second Brain to many of us.
We use it frequently.
It uses white screen which consumes high power.
If Google had a black screen,
taking in Account the huge number of page views,
according to calculations, 750 mega watts/hour
per year would be saved..!!!!! !
In response, Google created a black version
of its search engine, called Blackle,
with the exact same functions as the white version,
but obviously with lower energy consumption
