17. Use solar energy for producing electricity (Photovoltaics)

Another way of using solar energy is to produce electricity. The system is called photovoltaic system and it uses solar cells or photovoltaic arrays to produce electricity from the sun light. Solar cells could be placed on the roof or near the house. The power of solar cells is measured by W/sqm (Watts per square meter). Photovoltaics or generally “electricity from the sun” is sometimes called as the power of future. If you use clean solar energy, you don’t need to burn fossil fuels any more and that means no more pollution.

Impact: reduce pollution, save money, reduce electricity consumption

16. Use solar energy for water heating

If your geographic position has a lot of sunny days then you should use solar collectors to extract the energy from the sun and to transform this energy into hot water stored in water heaters – boilers. You can place collectors on the roof or near the house, maybe on garage or somewhere else. There are many different types of collectors available and a lot of experience with installing the solar system also. If you use clean solar energy, you don’t need to burn fossil fuels any more and that means no more pollution.
