5 uses of solar energy
Our earth gets most of its energy from the sun. We call this energy solar energy. Sol means sun. Solar energy travels from the sun to the earth in rays. Some are light rays that we can see. Some are rays we can’t see, like x-rays. Energy in rays is called radiant energy. The sun is a giant ball of gas. It sends out huge rays of energy every day.
Most of the rays go off into space. Only a small part reaches the earth. When the rays reach the earth, some bounce off clouds back into space—the rays are reflected. The earth absorbs most of the solar energy and turns it into heat. This heat warms the earth and the air around it—the atmosphere. Without the sun, we couldn’t live on the earth—it would be too cold.
We Use Solar Energy
We use solar energy in many ways. During the day, we use sunlight to see what we are doing and where we are going.
FOOD
Plants use the light from the sun to grow. Plants absorb (take in) the solar energy and use it to grow. The plants keep some of the solar energy in their roots, fruits, and leaves. They store it as chemical energy. This process is called photosynthesis. The energy stored in plants feeds every living thing on the earth. When we eat plants and food made from plants, we store the energy in our bodies.
We use the energy to grow and move. We use it to pump our blood, think, see, hear, taste, smell and feel. We use energy for everything we do. The energy in the meat that we eat also comes from plants. Animals eat plants to grow. They store the plants’ energy in their bodies.

Solar Energy – The Alternative Source of Energy

asked:
The fact is that the cost of energy keeps rising, and alone is forcing people to look the other direction for cheaper alternatives to energy. Solar energy has been one of the alternatives that people have found to have cheaper energy. Solar energy offers one more than one advantage, but it also has its limitations.
Solar energy is controlling the sun to create energy. The sun is a renewable source of energy. It is available to everybody around the world, and through research people have found a way to capture the energy of the sun and put it to use.
To use solar energy, one has to find a way to capture energy. This is where solar panels come in. Solar panels collect the energy of the sun. That energy that is collected may be converted to power or it may be stored and used later.
If you are collecting the sun’s energy, it is important that you have a storage unit. The reason being is that the sun is not around on rainy days to produce energy for those that require and depend on it. At night and also on cloudy days, the sun and also its power are not always available. In order to have an effective and efficient energy unit it is important that there is a way that the energy that it collects is stored and not used immediately, but may be used later.
