In their words:

First and foremost, our servers, and thusly your websites, are 100% Clean Wind Powered. Clean Wind is 100 percent new wind power. This carbon-free power comes from wind farms here in the Northwest and is endorsed by such groups as the
Renewable Northwest Project, Northwest Energy Coalition and Natural Resources Defense Council.

They go much further than wind energy and promote minimal commuting by employees, offset their employee’s carbon footprints and plant a tree on customers’ behalf.
