Other ISPs rely on electricity obtained from local utility companies to power their computer equipment. What you may not realize is that most electricity comes from coal, oil, natural gas, nuclear fuels, and large hydropower facilities. These conventional forms of energy contribute to global warming, acid rain, ecosystem destruction, and degradation of water quality. In fact, electric companies produce more air pollution than any other source - even automobiles.

There are also hidden economic costs associated with electricity generated from fossil and nuclear fuels. Acid rain causes more than $5 billion in damages each year to crops, forests, lakes, and buildings, while air pollution costs the American public an estimated $20 billion in health care annually.

Due to the recent growth of e-commerce and professional/recreational use of online services, the Internet economy now uses more energy than America's paper and steel industries combined. Choosing an ISP that uses renewable energy sources is a simple and effective way for people to make an immediate environmental difference and help build a sustainable future.
