The energy in biomass, wind, solar energy and fossil fuels originally come from the Sun. Solar energy is the source of most energy on Earth.
Solar energy is a truly renewable energy source. Solar energy can also be integrated into the materials used for buildings.
- Reduced dependence on foreign oil and fossil fuels
- Renewable clean power that is available every day of the year, even cloudy days, produce some power
- Return on investment, unlike paying for utility bills
- Virtually no maintenance as solar panels last over 30 years
