Big technology companies have been major purchasers of wind and solar power, and Google has been the biggest of them all. Alphabet bought enough renewable energy last year to match the power needs of all its data centres and global operations, making it the biggest corporate buyer of renewable power in the US. The company has used about 7 terawatt-hours of electricity to run all of its global operations last year, and the combined energy purchase contracts of the company have resulted in more than $3bn of investment in wind and solar farms globally. Alphabet is followed closely by Microsoft who announced in March that it will buy 315 megawatts of solar power as part of the largest purchase of photovoltaic energy in the U.S. – Bloomberg & Financial Times & Bloomberg
