Google has a power bill which would make most people wince with more data centres than you can poke a stick at. It said that its engineers have spent years perfecting Google’s data centres, making them 50 percent more energy efficient than the industry average.
“ But we still need a lot of energy to power the products and services that our users depend on. We began purchasing renewable energy to reduce our carbon footprint and address climate change — but it also makes business sense,” the outfit said.
However apparently thanks to spending a fortune on solar and wind powered systems, Google will reach 100 percent renewable energy for its global operations — including data centres and offices.
“We were one of the first corporations to create large-scale, long-term contracts to buy renewable energy directly; we signed our first agreement to purchase all the electricity from a 114-megawatt wind farm in Iowa, in 2010. Today, we are the world’s largest corporate buyer of renewable power, with commitments reaching 2.6 gigawatts (2,600 megawatts) of wind and solar energy. That’s bigger than many large utilities and more than twice as much as the 1.21 gigawatts it took to send Marty McFly back to the future,” Google announced.
Some of this was possible because over the last six years, the cost of wind and solar came down 60 percent and 80 percent, respectively, proving that renewables are increasingly becoming the lowest cost option.
It has cost Google more than $3.5 billion globally, and the projects generate tens of millions of dollars per year in revenue to local property owners, and tens of millions more to local and national governments in tax revenue.
