Ever since scientists discovered materials that can produce electric current by simply being exposed to light, people have been excited about this energy source. Here comes the sun, the free giant nuclear reactor within our solar system generates over 430 x 1018 joules per hour; more than the energy all humans consumed in the year, 2013. Clearly, we have a source of virtually inexhaustible and clean energy in the form of solar energy that we are just not making use of it.
Technologies to harness solar have been of a major concern over the years but the most used types are solar photovoltaic technology and concentrated solar power. Focusing on solar photovoltaics …
The potential to harness solar power was first discovered in 1839 by the French physicist, Alexandre Edmond Becquerel. A number of scientists have ever since worked and improved Becquerel’s discovery. In 1953, Physicists at Bell Laboratories discovered silicon to be a more efficient element to convert light to electricity. This discovery led to solar cells capable of powering electrical equipment and new breeds of designed PV cells to use in space. This technology also found its way into the application of telecommunications equipment in remote areas on earth. In the 1970s and 1980s, people began using PV modules to charge batteries and then used those batteries to run various lights and appliances. Today, modern solar energy technology knows no limit as it can be applied to every electrical related field. Its applications extend from the calculators to the drones.
I’d put my money on the sun and solar energy. What a source of power – Thomas Edison
Here comes the sun, expected to produce clean and free energy for the next 5 billion years. An energy source several times greater than the total human energy consumption. Available nearly everywhere, we should not wait till oil and coal run out.
