Solar Energy

“Energy cannot be created or destroyed; it can only be changed from one form to another”, these were the words stated by an ingenious man, named Einstein, in his theorem on Conservation of Energy. One of the most available forms of energy that can be found here on earth at any given time is solar energy. Solar energy is a form of energy that is emitted by the sun. This energy can be harnessed and processed using the technologies that is available to exploit it into renewable green energy with zero emission. Currently there are different types of technologies and machineries that are capable of harnessing solar energy; some of them include solar heater, photovoltaic cells, and concentrated solar power generators. Surprisingly, utilizing solar energy is not a modern invention. Many years ago, for centuries the ancient Chinese, Romans and the Greeks had used different architectural settings to passively use solar energy to heat, cool and light their homes and other buildings (Hoffman 1052). Nowadays similar form of architecture is still in use that takes advantage of the suns position to insulate buildings. Most of the solar powered technologies were invented in the late 20th century, but because of an abundance of fossil fuel and more efficient alternatives only one solar technology, photovoltaic cell also known as solar panels, was able to flourish. Although gas and oil is cheap and have a broader field of usage, I believe that harnessing solar energy to heat up water and power homes or offices are a more viable option because unlike coal or gas it does not produce carbon dioxide, sulfur dioxide or any other greenhouse gases, it does not have any harmful byproduct and it is safe for the environment.
