It takes a lot of energy to power and maintain servers for a web host. Therefore one of the most important things you as a blogger or webmaster can do is to choose a green web host.

With green web hosts I mean hosting companies that power their servers with renewable energy such as wind and solar power. Some of these green web hosts generate their own energy via renewable energy sources. Other web hosts offers carbon offsetting, discounts to non profits, letting their employees telecommute, etc.

Please check out our Green Web Host page for a more up-to-date list on Green Web Hosting Alternatives.

So which host should you choose then? Which is the best? I am sorry but I can’t tell you which host is the best because I haven’t tested all of them. You should always do a background check on any host you are interested in. See if they got some testimonials from customers. But any of these web hosts are better than your current one that isn’t doing anything at all to prevent global warming.
