Answer 2

Solar Energy


Energy is the ability to do work, and 'solar' is a Latin word for the sun. So, we can define solar energy as energy obtained from the sun. We can put this energy to work for us in many ways, from heating water and living spaces within our homes to generating electrical energy. Solar energy is a type of radiant energy, so named for the vibrating particles 'radiating' from the sun.Solar energy is sometimes called solar radiation for this reason.

Solar energy also does other kinds of work that is more indirect. Plants use the sun's energy through the process of photosynthesis to grow, and, more indirectly, we eat plants like fruits and vegetables to provide our bodies with energy. The sun is such an important part of life on Earth that it's not surprising that so many end-of-the-world science fiction movies begin with the sun not doing its job properly.
