An Earth Day treat: lots of renewable energy for our Iowa data center

We’ve been talking to MidAmerican Energy, our energy supplier in Iowa, about renewable energy since we started building our Iowa data center in 2007. Just in time for Earth Day, we now have a freshly inked agreement with MidAmerican Energy to supply our Iowa data center facilities with up to 407 MW of 100% renewable wind energy, as tracked by renewable energy certificates. This agreement will not only cover our current facilities but will allow for future expansion supplied by renewable energy as well.

This is our seventh and largest renewable energy commitment to date, bringing the total amount of renewable energy we’ve contracted for to over one gigawatt (1,000 megawatts).

We’ve entered into a few different kinds of agreements over the years - sometimes signing power purchase agreements (PPAs) with wind farm developers and sometimes working with our local utility partners. This agreement is similar to our 2012 agreement with our Oklahoma utility, the Grand River Dam Authority. In this case, MidAmerican Energy will sell energy to our Iowa data center bundled with and tracked by renewable energy certificates generated by projects that are part of its Wind VIII program.

PPAs and agreements like this one are a big part of the commitment to carbon neutrality we made back in 2007, and we’re working to make this whole process easier for other companies by advocating for renewable energy tariffs. Depending on the circumstances, any of these approaches can make sense, and we’re always on the hunt for new and creative ways to power our operations with renewable energy. But it’s not just our own operations we want to green: Google has also invested over $1B in 15 renewable energy investments around the world in an effort to put more renewable energy on the grid and reduce global greenhouse gas emissions.

We’ll continue working with MidAmerican Energy and all of our utility partners to find diverse ways to deliver clean, renewable energy to our data centers. Happy Earth Day!
