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)
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
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)
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.
In chapter thirteen of our book, Environment by Raven and Berg, it shows us just how important renewable energy sources are. Currently the United States of America thrives on the use of fossil fuels and nuclear power. The main problems with these types of fuel are that they are both limited and can be extremely harmful to our environment. They cause global warming, air pollution, acid rain, and oil spills (Environment), and not only that, but in the grand scheme of things, these sources really aren’t even that cheap of a fuel source. There are many alternatives to these all but outdated fuel sources.
The United States currently relies heavily on coal, oil, and natural gas for its energy. While the price of natural gas per barrel continues to plummet, the United States is constantly seeking new sources of renewable energy. Renewable energy consists of any type of natural resource (solar power, ocean power, wind power, rain, snow, etc.). that naturally and automatically replenishes itself. Renewable energy is important because it is infinite and everlasting, meaning our children and our children’s children will be able to utilize these resources long after we are gone.
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.
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).
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.
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.
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....
Why do we need to rely on renewable sources? Most of the energy that we use today comes from fossil fuels such as natural gas, coal, and oil. All of these resources are non-renewable, so you can finish one day. In order to have a better world and a healthy environment for the future, people are trying to obtain energy from natural resources instead of non-renewable sources. In the lecture “Renewable energy resources” (2014), Mistry focuses on some advantages and disadvantages of renewable energy.
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.
