SOLAR ELECTRICITY
Consider applying for a "green" or home equity loan to install solar panels (also called photovoltaic). Over time, the system can pay for itself through energy savings, profits from selling extra electricity to the utility (called net metering), tax credits, and real estate appreciation.
