One common quip about switching to renewable energy and energy efficient appliances is the higher initial start-up costs. However, there are many, many opportunities to get money for implementing energy-saving changes to your business or home.
One website, the Database of State Incentives for Renewables and Efficiency, lists many of the possible incentives and grant opportunities that you can apply for from the state, federal government, and major utility companies.
Grants, incentives, and other financial aid exist for solar, wind, geothermal, and other types of renewable energy, as well as for general energy efficiency.
