Generating electricity using your own small renewable energy system fits the circumstances and values of some home and small business owners. Although it takes time and money to research, buy, and maintain a system, many people enjoy the independence they gain, and the knowledge that their actions are helping the environment.

A renewable energy system can be used to supply some or all of your electricity needs. Some people, especially those in remote areas, use the electricity from their systems in place of electricity supplied to them through the grid by power providers (i.e. electric utilities).

Others connect their systems to the grid and use them to reduce the amount of conventional power supplied to them through the grid. Connecting your system to the grid allows you to sell any excess power you produce back to your power provider.

The renewable energy technologies available for use today include photovoltaics, small wind turbines, and very small hydropower ("microhydro") projects. These technologies can be used by themselves, they can be combined, or they can be used in conjunction with a fossil fuel generator to meet your particular needs.

Choose from the main topics in this section to learn about the technologies, policies, and issues you might encounter in setting up a system to generate your own electricity. The information here is only a guideline; rules and policies vary dramatically between communities. If you buy or install your system using a local renewable energy company, they will be familiar with your local policies, and can help you through the planning and permitting process. In addition, your state energy office may be able to provide guidance on local procedures.
