The technology giant signed a deal with MidAmerican Energy, who will supply Google’s Iowa operations with the wind-generated power and allow the company to expand its renewable energy usage as required.

“At Google, we pursue a variety of approaches to power our operations with renewable energy,” said Google’s director of global infrastructure Gary Demasi.

“One great way to do this is by working with our utility partners like MidAmerican Energy, and we hope this agreement will inspire all of our utilities to work with us in finding ways to increase the supply of clean power,” he added.

This latest announcement is Google’s seventh and largest renewable energy commitment to date, bringing the total amount of renewable energy contracted to more than one gigawatt (1,000 megawatts).

In January, Google committed $75m (£45m) in a 182 megawatt (MW) wind farm in Carson County, Texas while in November 2013 it announced an $80m investment in six utility-scale solar facilities in California and Arizona.

Google’s announcement follows an update from Apple who reported its progress on environmental targets, claiming 94% of its corporate facilities are now powered by renewable energy.
