Renewable Energy

Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable. Which means that the energy dissipated is naturally replenished.

Renewable energy replaces conventional fuels in four distinct areas: power generation, hot water/ space heating, transport fuels, and rural (off-grid) energy services. Renewable energy is one of the safest form of energy generation.

You have many options for using renewable energy at home—from solar-powered outdoor lights to buying renewable energy from your utility to even producing solar electricity at home with photovoltaic (PV) cells.

Renewable Energy Tips

• A new home provides the best opportunity for designing and orienting the home to take advantage of the sun’s rays. A well-oriented home admits low-angle winter sun to reduce heating bills and rejects overhead summer sun to reduce cooling bills. See the Heating and Cooling section for more about using passive solar energy in your home.

• Many U.S. consumers buy electricity made from renewable energy sources like the sun, wind, water, plants, and

Earth’s internal heat. This power is sometimes called “green power.” Buying green power from the utility is one of the easiest ways to use renewable energy without having toinvest in equipment or take on extra maintenance.

• Another use of solar power is for heating water. If you have a swimming pool or hot tub, you can use solar power to cut pool heating costs. Most solar pool heating systems are cost competitive with conventional systems. And solar pool systems have very low operating costs. It’s actually the most cost-effective use of solar energy.

          Long-Term Savings Tip

• If you’ve made your home as energy efficient as possible, and you have very high electricity bills and a good solar resource, you might want to consider generating your own electricity using PV cells. New products are available that integrate PV cells with the roof, making them much less visible than older systems.

If the following conditions apply, you might want to do more research to see if investing in PV is right for you:

• Your site has adequate solar resources.

• A grid connection is not available in your area or can be made only through an expensive power line extension.

• You are willing to pay more up front to reduce the environmental impact of your electricity use.

• Your power provider will connect your system to the electricity grid and buy any excess power you produce.

• Your state, city, or utility offers rebates, tax credits, or other incentives.
