The simplest answer to the question, why I selected “solar energy” for my essay is that, it is the cheapest resource and the more important fact is that it will never terminate. It is currently being used to power solar cars, heaters and other important things but since it is a new invention, it will take some more time to influence the world. Inventors opened the mysteries of transforming the sun 's beams into mechanical power more than a century ago. In 1767 a Swiss scientist named Horace-Benedict de Saussure created the first solar collector, it was an insulated cubical box, layered with glass to absorb heat energy. The box later became known as the solar oven producing heat at 230 degrees Fahrenheit. In 1839, another milestone in the solar journey was achieved as a French scientist, Edmond Becquerel defined the photo voltaic effect. He placed two electrodes in an electrolyte and passes sunlight through it, as a result electricity was produced. In easy terms, photovoltaic effect is the creation of potential or electric current in a substance upon exposure to sunlight. In 1947, solar power equipment became popular in the US and there was a huge demand of solar equipment amongst the masses.
From 1959 to 1970, there were discussions about
