Research Paper – Solar Energy Blakely J. Phillips BGEN 440, Montana State University - Billings Introduction Solar energy is the conversion of power from the sun to usable electricity (Alternative Energy, 2014). The most common source of solar energy utilizes photovoltaic cells to convert sunlight into electricity (Alternative Energy, 2014). Photovoltaics use a semi-conductor to absorb the radiation from the sun, creating and emitting electrons, which are then harnessed and used as electricity (Alternative Energy, 2014). Pros of Solar Energy There are many advantages of using solar energy. It is renewable, abundant, sustainable, environmentally friendly, and more. Solar energy is a renewable energy source, which means that unlike non-renewable energy sources such as fossil fuels, coal, and nuclear energy, we cannot run out of solar energy (Maehlum, 2014). As long as the sun is alive, which according to NASA is another 6.5 billion years, we will have access to solar energy (Maehlum, 2014). The true potential of solar energy is astounding and overly abundant. The surface of Earth receives 120,000 terawatts of solar radiation, better known as sunlight, which is 20,000 times more energy than what is needed to supply power to the entire world (Maehlum, 2014). Solar energy is not only abundant and renewable it is also sustainable and environmentally friendly. As a sustainable energy source, solar energy is able to meet the needs of the present without compromising
