Solar radiation

Solar radiation is the energy (or light) that comes from the sun. It is the main source of energy for life on Earth. When the sun's rays reach us, they are called sunlight. Solar radiation provides us with warmth and light that we need to live. Plants use sunlight to make food from carbon dioxide and water. This process is called photosynthesis. Solar radiation is also used to create electricity from solar panels that are placed on roofs or in open spaces.
