Recommended: Renewable energy and fossil fuel
Renewable energy is a type of energy source that does not have an ending to it from its consistent replenishing. Differential to fossil fuels that cause harm to the Earth, renewable energy is made from natural sources that don’t cause any harm with carbon dioxide or pollutants. There are four different types of alternative energy: nuclear, solar, wind, hydroelectric. The purpose of this paper is for the reader to better understand the use of alternative energy along with the positive and negative impacts it has on the world. The process of nuclear energy becoming a form of electricity stems from nuclear fission. Nuclear fission is atoms being split to release energy in a nuclear reactor. The nuclear reactor is composed of fuel elements, moderate, and control rods and is enclosed in thick concrete walls. Uranium pellets are the elements used in fission that cause chain reactions of the splitting of atoms. As this chain reaction continues, and the …show more content…
The first disadvantage is that there is more energy being used than there are sites to make energy from renewable resources. More sites may have to be built which would increase the initial cost, or, using less energy. More energy is produced with smaller portions of non-renewable resources. There is an argument that the weather could cause us to not have enough energy if there is not the right weather condition. Hydroelectric energy needs rain, wind power needs wind, and solar power needs sun. Without the control over the conditions outside, there would have to comprise energy. Other disadvantage arguments states that wind energy it causing changes to the wind pattern. The final disadvantage is the cost. This may seem contradictory to the advantages of cost, but the startup cost of these operations is more expensive. Solar power in houses cost more money initially for the consumer for the solar
Nuclear energy must be a consideration for the future with the rapidly depleting supply of fossil fuels. This type of energy can be created through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together to form helium. In the long run, nuclear fusion has greater potential than fission.
Nuclear Power comes from the process of splitting Uranium Atoms (also called fission), which in turn releases copious amounts of energy in the form of heat. When the atoms are arranged in a reactor, the splitting of an atom will cause nearby atoms to split, forming a chain reaction. As the energy is released, it is sent through coolant tanks full of water, which is then heated into steam. The steam is channeled and used to spin a turbine, which in turn powers a generator,
Nuclear energy is produced during the process named nuclear fission or nuclear fusion. The development of nuclear energy started in the 20th century and there is now worldwide recognition for using nuclear energy. Popular countries that operates nuclear power are United States, France, Japan, and Russia, the nuclear energy generates up to 6% of the world’s electricity supplies. Even though the energy is mostly used by many countries, but it may causes side effect to the living things in the environment. (WNA, 2012)
The entire nuclear energy process starts with uranium. Uranium is the fuel for the nuclear reactors, often harvested near coal mines. Uranium is found in two types, U-235 and U-238, the one needed for the nuclear energy power is U-235. Uranium U-235 is one of the least plentiful elements making only 0.000002 percent of the earths’ crust. Although it is quite rare, one pound of Uranium can produce the same amount of energy as three million pounds of coal. U-235 is unstable in nature and highly radioactive making it a perfect match in the fission process. (How Nuclear Power Works 2)
Nuclear power is generated by using electricity created during a controlled fission or fusion reaction (“Nuclear Energy.” Global Issues in Context Online Collection). Nuclear fission is a process that releases energy when a nucleus in one atom is separated into two nuclei. Nuclear fusion occurs when the nuclei of two hydrogen atoms are fused together producing a larger nuclei along with energy (“Nuclear Energy.” Opposing Viewpoints Online Collection). In the 1950s, the use of nuclear power became a realistic idea for countries with nuclear capabilities and nuclear power programs (“Nuclear Energy.” Global Issues in Context Online Collection). The international nuclear program grew rapidly and by 1999 there were 436 nuclear power plants in 32 different counties. The United States, Japan, Canada, Russia, India and France remain the largest users of nuclear energy since the 1990s; however, the dependency on nuclear power varies greatly around the world because of differences in the individual nuclear power programs availability of needed resources (“Nuclear Energy.” Opposing Viewpoints Online Collection).
Energy is the basic necessity of daily life. Nowadays, dependence on fossil fuels for energy needs becoming lower in numerous countries due to the potential of renewable energy to supply sustainable energy to the huge populations in many developing countries who are short of clean and continues energy. Generally, renewable energy can be defined as energy that is derived from natural resources which are constantly replenished and theoretically inexhaustible. Fossil fuels on the other hand can be described as energy that cannot be renewed and will eventually diminish. Thus, in many developing countries renewable energy is the alternative energy to replace non-renewable energy or commonly known as fossil fuels. In addition, according to Sorensen (2004), there is a greater demand for renewable energy sources nowadays due to the uncertainty of fuel price rise in living expenses. Commonly, there are many types of renewable energy available in our world such as wind power, biomass energy, solar energy, hydroelectric power and geothermal energy. However, the main three example of renewable energy are hydroelectric power, solar and biomass energy (Refer to Figure 1 in Appendix 1).
In the debate of traditional energy vs. renewable energy the clear winner is renewable energy. Renewable energy is vastly superior over traditional energy because it decreases dependence on foreign resources, produces no emissions, and is not limited in quantity. Opponents of renewable energy are likely to argue that this is not the case and that instead, traditional energy is better because it creates job growth, is reliable during all hours and climates, and comes with a lower cost. These advantages however are either misconstrued or hardly outweigh the long-term positive benefits of renewable energy.
Wind power is another form of solar power. Wind isn’t only a clean fuel source, but it is one of the most inexpensive e alternative sources of energy. Just as long wind continues to blow and the sun shines then wind power can produce energy to send to many different areas. There aren’t many locations that have continuous wind. And because of that the widespread development of wind power isn’t as great as it could be. Although there are more advantages than disadvantages when it comes to this energy source, the disadvantages should be taken just as seriously. Wind power can harm animals, there was a study that stated birds were coming in contact with turbines and dying. For many people the noise from the turbines is unbearable, and that’s something else that should be taken into
To begin, nuclear power is produced by nuclear fission, which is the splitting of an atom to start a chain reaction (“11 Facts”). This chain reaction produces massive amounts of heat. Nuclear reactors take advantage of this heat by pumping water into the reactor, which in turn produces steam. The steam then becomes pressurized through a pipeline and exits into a turbine (“How do Nuclear”). The pressurized steam causes the turbine blades to spin, producing power which is linked to a generator for use in the main power lines. When the steam passes the turbine blades, it goes past cooled pipes and condensates (“How do Nuclear”). After the condensation process is finished and the steam reverts back to water, it is pumped into the reactor again, thus completing the process of producing nuclear-based power.
I believe any negative economic effects that the transition from traditional to renewable energy may have on our economy would be counteracted by the plethora of positive effects that would come about as a result. According to ucusa.org, renewable energy already supports thousands of jobs in the United States alone. For example, in 2011, the wind energy industry directly employed 75,000 full-time-equivalent employees in a variety of capacities, including manufacturing, project development, construction and turbine installation, operations and maintenance, transportation and logistics, and financial, legal, and consulting services. Other renewable energy technologies, such as the solar industry, employ even more workers. According to the National Solar Job Census taken in 2011, over 100,000 people were employed both part-time and full-time within the industry. That data alone is a promising figure considering renewable energy is still in it’s
The examples of using renewable energy are The Solar Panel which is an assembly of solar cells. The solar cells convert solar energy into electrical energy. The solar panels are very expensive even though they cost nothing to run. They are installed in places which must have sunlight. The efficiency is 10-20% the environmental impact is it needs very large areas, 40km² is needed to produce to produce the equivalent power of one modern power station. Does not cause pollution but there are environmental concerns about the production of storing devices.
One of the most compelling arguments for the use of renewable energy is how many forms exist of it. Nuclear power, solar power, wind power, tidal power, hydroelectric power, pumped storage, wave power, geothermal power, biomass, and biogas are the most widely known renewable energy sources (Darvill, 2013). This large selection of fuels supports the idea of renewable fuels one day powering the entire planet. All the sources of energy have different niches and benefits. Solar energy is extremely effective when providing energy for small establishments such as a house or small store, but hydrothermal power would be a more plausible solution for factories or large establishments....
Although renewable energy can be expensive to build, it has less environmental damages in comparison to non-renewable energy. Besides the natural resources such as sun, wind, water and hydrogen, we also have geothermal power, and biofuels as renewable sources. First of all, solar energy is the energy produced when the sun heats the solar panel. Thus, when the sun heat the panels, it produces electricity. Solar power produces energy during the day and can storage energy for the night. Solar power does not pollute so much the environment. However, it has high maintenance cost, and it takes a large land space. Secondly, 15% of World electricity comes from wind. In order to have wind energy, it is important to have turbines to get the wind in order to produce electricity. Tall turbines produce more energy. The drawbacks of wind power are that it requires steady wind and its installations may interfere with TVs, cellphones, and other electrical devices. However, it is quickly built and there is no pollution nor noise produced. Third of all, the water falls in the dam can also generate electricity. For instance, 19% of world electricity comes from water. Regardless of the fact that hydroelectric power has low maintenance costs and does not pollute the environment, it can cause earthquakes, and destroy wild rivers. Only 0.3% of world energy
Global warming is an extremely important and troubling aspect of the world’s current situation. This is due to the fact that the majority of the world’s energy production is from non-renewable energy sources, which are energy sources that either can not be naturally replenished or require thousands of years to be restored. Based on our current energy usage growth rates, there are an estimated 100 years left before our natural resource reserves are exhausted. (Non Renewable Natural Resources: How Much Is Left, Environmental Thinker) China alone consumes nearly as much coal as the combined usage of coal from the rest of the world. (US Energy Information Administration, China Consumes Nearly as Much Coal as the Rest of the World Combined) There is visible evidence of this happening with the increasing pollution levels. Carbon Dioxide and Methane pollution levels in the world reached a record high in 2012 and are 260% higher than the pre-industrial levels. (UN: CO2 Pollution Levels at a Record High, John Heilprin) Converting our world into a more renewable energy dependent society is the most advantageous and likely method for preserving our dwindling fossil fuel supply while also protecting the world that we call home.
Nuclear energy is generated by a process called fission. Fission occurs within the reactor of a nuclear power plant when a neutron is fired at an atom of uranium causing it to split and release subsequent neutrons.1 These are able to crash into other uranium atoms causing a chain reaction and releasing a great deal of heat energy.
