This chart, shared by World Economic Forum shows Google as an industry leader when it comes to using renewable energy sources to meet the needs of power in its operation. In 2016, Google is committed to buying 2.6 gigawatts of the wind and solar energy.

Google said that it would go 100 percent renewable energy by the end of 2017.

Commitment like this from giant corporations like google is one of the biggest of worries for traditional energy sources like coal and oil.
