    Renewable energy comes from the sun directly or indirectly. Sunlight, or solar energy, can be captured and used directly for generating electricity, other buildings and lighting and heating homes, and for, solar cooling, hot water heating and a variety of industrial and commercial uses. Wind turbines are used to capture the wind and convert it to energy which is driven by the sun’s heat. Then, the heat from the winds and sun causes water to evaporate. Energy can be captured using hydroelectric power

    Energy is the prime component of all things running in the universe. Earth uses one very small fraction of the suns energy to sustain its life through the process of photosynthesis. Photosynthesis further leads to production of oxygen and glucose which are the source of survival for humans and all living beings on earth. The energy used in the form of mechanical, kinetic or electrical energy also sources itself from the solar energy or from the product of photosynthesis directly or indirectly (Fossil

    source for energy generation for centuries, due to its reliability and relatively low cost. However, with coal reserves slowly diminishing due to the ever-increasing demand for energy, renewable energy sources are becoming more popular. Renewable energy is energy harvested through natural processes like sunlight and wind. These sources are replenished faster than they are consumed, and the methods used to convert them to energy do not create any pollution. Simple applications involving renewable energies
