Google is minimizing their power consumption by designing and building some most energy-efficient servers and data centers that using half the electricity of a typical data center. How Google becoming more greener? \tMountain View campus has 1.6 MW of solar panels produce 3 million kWh of clean energy. \tFrom the solar panels roofs to bike-to-work program, these initiatives eliminate the equivalent of more than 10,000 metric tons of CO2 per year. \tGoogle invested more than $780 million in the renewable energy sector, including investments in promising renewable energy projects capable of generating 1.7 GW of power and electricity equivalent to that used by 350,000 homes, beside having in-house renewable energy supply. So, this are the facts and figure regarding Google's Green movement. We will update more information regarding green computing, cloud and Google in our upcoming articles.
