In the next fifty years, energy supply will become a major issue all over the world that natural resources will nearly be exhausted, such as fossil fuels.There are two kinds of energy, which is depleted energy and renewable energy. Alternative energy has become considerable options for mankind to seek for sustainable energy. This essay classifies alternative energy based on their source into three types, which comes from sunlight, wind, and nuclear. One type of alternative energy is solar energy. The sun is the main source power of solar energy, which is transform into electrical or thermal energy (Solar energy, n.d.). There are three kinds of solar energy that is solar thermal energy, photovoltaic solar power, and concentrating …show more content…

A wind turbine looks similar to a fan that the wind turns the blades to spin, then it will create electricity (Wind energy basics, n.d.). There are two principal kinds of wind energy based on a horizontal axis and a vertical axis (Meyers, 2013). According to Meyers (2013), a horizontal axis has to encounter with the wind, so blades can spin and generate electricity from the top of a tower, and a vertical axis does not necessary to directly face wind. One study revealed that larger winds are able to distribute bulk power, and the costs are justifiable (Wind turbines work, n.d.). The notifiable advantages of wind energy are unlimited and substitutable resources, and also increased economy, cost effectiveness, and harvesting facilities (Lloyd, 2014). Other benefits of wind power are installed in a small-scale space, increased a great deal of employment rate, and non-polluting undesirable gases (Silva, 2014). Furthermore, technicians who work with wind solar have to wear a uniform properly, such as hard hats, harnesses, and safety goggles before go in a turbine (Wind turbine technician, 2014). One study showed that there is a remarkable health and safety record of the wind energy over past 20 years that there are more than 100,000 devices provided worldwide, and also none workers who got injuries from the machines (Wind farm safety, …show more content…

Nuclear power is included several atoms (Nuclear power, 2015). Nuclear power has two sorts, which is fission and fusion that a large amount of power form are accumulate in the atoms of numerous components (The ten types, n.d.). This will convert to energy based on suitable conditions. Additionally, the beneficial of nuclear energy is to created jobs, and stimulated economic growth (Costs and benefits, n.d.). It also referred that in the United States, electricity sales and revenue have rise from 40 to 50 billion dollars every year. One study of CNN news reported that in the United States, the 103 nuclear industry has generated electricity for over 20 percent since 1978 (Roderick, 2013). Moreover, nuclear energy is not only a primary global energy source, but also the largest source of free electrical emission (Benefits Nuclear Energy, n.d.). In addition, the meaning of nuclear safety is the accomplishment of avoided nuclear accidents, protected workers, and against dangerous impacts of radioactive material and ionizing radiation (Nuclear energy, n.d.). Other study of CNN, There was a proof that the safest form of alternative energy is nuclear power in the United States over past 50 years (Roderick, 2013). Another study found that commercial operation recorded that nuclear power is not harmful because it collected experience of over 12,000 rector for many years (Comby, n.d.). In conclusion, this essay has divided
