Unless you are a hardcore road warrior and do all of your business from the back of your car, you need to contract electricity. Of course, another option is to generate your own electricity through a small-scale wind farm or solar panels. This is generally not an economic choice, however, especially for companies that have just started. Each state has an energy department that offers advice and tips on how to minimize the cost of electricity and ensure your appliances are as efficient as possible. You can also find help and advice at the U.S. Department of Energy Information Administration's official website.
