what is solar energy?why do we need solar energy? How is it useful?
Answers
Answer:
Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.
The main advantage is that it is a renewable, clean source of electricity. Solar power is also scalable. ... When it's used on a small scale, extra electricity can be stored in a battery or fed back into the electricity grid. Overall, the sun gives off far more energy than we'll ever need.
Our sun is the source of all life on Earth, and solar energy is useful to us in many different ways. The sun creates two main types of energy – light and heat – that we can harness for many activities ranging from photosynthesis in plants to creating electricity with photovoltaic (PV) cells to heating water and food.
