Cause Paper for the Development of Solar Energy
Our modern industrial civilization is based mostly on using fossil fuels for power plants to produce electricity and to fuel vehicles for transportation. Oil, which is the most precious and efficient source of energy, has already started to be exhausted due to heavy overpopulation, industrial demands, and scarcity of resources. The oil crisis in 1970 caused scientists all over the world to look for substitutes to fossil fuels to avoid economic and industrial collapses. Experts in the field of sustainable energy have turned their attention towards solar energy. Thomas Edison, the ...view middle of the document...
This resulted in the release of radioactive materials into the air and in sea causing cancer in the people who live close to the plant. Another well-known incident is the BP oil leak in the Gulf of Mexico which spilled over a million cubic meters of crude oil into the gulf. This event had a large impact on the birds, fish, and other wildlife whose habitat is in the gulf. Using solar energy would not have made such a large impact on the wildlife as those fossil fuels did. Sunlight has been a constant source of energy for billions of years. All the forms of life on planet Earth are dependent on the food which is made with the energy of sunlight. Sunlight is continuously pouring its energy onto earth and, in fact, all other planets. Life processes on earth are taking place due to the energy derived from sunlight. Humans have developed technology to capture sunlight and use it to meet their energy needs. Sunlight energy only needs specially-designed solar panels that are connected to each other. When sunlight strikes the panel, it transfers its energy into the panels and it is systemized to convert the energy into electricity. Since solar energy relies on the sun to produce the energy what happens at night or when it’s a cloudy or rainy day? In order to provide electricity at night or on a dark day, the electricity made from solar energy needs to be stored in batteries (Walker 2007). The system is extremely nature-friendly and poses no hazard to the environment or to human health. Coal and gas are much cheaper but their impact on the environment and ecosystem is immense. The phenomenon of global warming and the greenhouse effect are due to the emissions of coal and gas driven industries and transportation (Tiwari, Solar Energy Technology Advances 3-4). In the 20th century, the average temperature of Earth rose one degree Fahrenheit. This was a period that saw the most aggressive population growth and industrial development in Earth’s history. The impact of global warming on the environment is extensive and affects many areas. In the 21st century the impact on the environment will get worse with the continued use of fossil fuels. For that reason fossil fuel use should be reduced and replaced with renewable energies like solar energy.
Besides being environmentally friendly, solar energy is also a renewable form of energy. Renewable energy is a form of energy which does not diminish upon using the source. Sunlight has been pouring its energy on Earth for billions of years and is expected to do so for many more billions of years. Other forms of energy like coal and gas are consumed and, therefore, their deposits are largely diminishing. It is estimated that most of these deposits will be diminished due to human consumption as soon as 2050 (Mudakavi 20). Unlike coal, which is extracted from their deposits and brought to industries for purification and other processes and then transported to the final destination where it is used for the...
