Solar energy is the kind of energy that can be derived from the rays of the sun. The rays are so powerful that many scientists believe they may be able to provide us with complete energy requirements in a very short while. If this is true, then we have a lot of technological advantages and a bright future ahead of us, but there is a dark side to it as well. The dark side of solar energy is the fact that it cannot be stored in large quantities for long periods of time. This means that once the sun goes down and is not active anymore, we have to start looking at other means of providing energy that can last us through the day or week without going into debt.
How it works is the process by which solar energy converts the heat of the sun into electricity. The heat is absorbed by the silicon in the solar cells and when exposed to an electric current, the energy is transformed into electrical energy. This electrical energy is then converted into alternating current which our homes use to power everything from household lighting and refrigerators to televisions and work equipment.
How it works is so simple and yet people are still looking for new ways to make solar energy more effective and cheaper. One day, perhaps a new breakthrough will be made and we will be able to rely on solar energy without having to mine for precious resources from deep inside the earth. Until that day comes, we need to make do with what we have. We can use the sunlight to help save our money and energy bills and we can also benefit from the savings we will make on our power bills as well as help preserve our environment.
