While there are currently no EPEAT or Energy Star ratings for hosting services and data centers, many green or at least "greenish" services exist. Hosting companies and data centers are taking on initiatives to improve the efficiency of cooling systems and manage the power consumption of servers, tapping directly into renewable power systems, buying green energy credits from utilities or purchasing "carbon offset credits" to mitigate their environmental impact.

If your server requirements are such that a green data center or hosting company isn't an option, purchasing green energy or carbon offset credits for your organization/office is another option. While going with a company that purchases these credits or buying your own through your utility or a third-party isn't the same as actually using green energy to power your computer systems, it is the next best thing.
