This past weekend, the blog switched web hosting services to FatCow. Hopefully this will first and foremost mean much quicker load times within the site, but another thing that drew me to FatCow in particular was that all of their hosting services are powered by wind energy. I’m always a little skeptical of claims like this, however, so I did a little bit of research. FatCow does not actually generate their own wind energy. This isn’t surprising- in the US most wind energy is produced on wind farms with large turbines- an installation to power just this web hosting provider would have been less efficient and far less practical than a wind farm. What FatCow does do is purchase Renewable Energy Certificates (RECs) to offset all of the energy used not only by all of their hosting services but also all of the energy used by their office staff. In fact, after offsetting their energy use for two years, FatCow has now been awarded membership to the U.S. Environmental Protection Agency’s 2011 Green Power Leadership Club.
