Solar energy is energy derived from sunlight. Whether you realize it or not, the sun already powers our planet, providing the necessary energy to keep our environment and population growing. … Solar energy can be used to provide heat, light, and other electricity-dependent needs in homes and buildings.
Why is it important to know about solar energy?
Solar is a safe alternative which can replace current fossil fuels like coal and gas for generation of electricity that produce air, water, and land pollution. … Use of solar energy will eliminate these unsafe, unclean consequences from using conventional fossil fuels.
Why is solar energy important to humanity?
All life on earth is supported by the sun. This amazing resource radiates energy and provides us both heat and light by fusing hydrogen into helium at its core. Still, we receive enough power from the sun to meet the power demands of all mankind — millions of times over. …
What do I need to know about solar power?
Solar power is energy from the sun that is converted into thermal or electrical energy. … Solar technologies can harness this energy for a variety of uses, including generating electricity, providing light or a comfortable interior environment, and heating water for domestic, commercial, or industrial use.
Why solar energy is bad?
Solar energy systems/power plants do not produce air pollution or greenhouse gases. … Some solar thermal systems use potentially hazardous fluids to transfer heat. Leaks of these materials could be harmful to the environment. U.S. environmental laws regulate the use and disposal of these types of materials.
