Disadvantages Of Nuclear Energy Essay

715 Words3 Pages

ADVANTAGES AND DISADVANTAGES OF BOTH COAL BASED GENERATION AND NATURAL GAS COMBINED CYCLE GENERATION The economic growth of a country depends on its ability to setup a highly suitable and reliable electricity sector. Electricity is generated in base-load plants in accordance with demand and transported over long distances to reach the consumer at the required voltages. Today the fossil fuel options are natural gas and coal and the technology options are coal fired conventional plants, coal fired IGCC (Integrated Gasification Combined Cycle plants) and natural gas fired combined cycles. Conventional plants are preferred to heavy fuel oils due to its high purification cost of exhaust gas and the higher cost in respect to coal. Coal energy is …show more content…

Abundance: There are an estimated 300 years of coal deposits still available. Also coal extraction from mines is relatively cheap hence making the price lower than other energy sources

4. Known technologies: The use and production of coal is well understood and more advanced technology keeps coming into play as the years go by to ensure there is constant supply of coal for power production.

DISADVANTAGES OF COAL GENERATION
1. Greenhouse gas emissions: The byproducts of coal pollute the environment and contribute a great deal to global warming. The increased amount of carbon emissions caused by coal fired plants has led to further global warming which results in climate changes.

2. Destruction of Mines: Mining of coal destroys the habitat of the environment. It also displaces humans living in those regions. Also places where coal is mined is unsafe for habitation as the ground could cave in at any time.

3. Emission of harmful substances: Thermal plants like coal fired plants emit harmful substances such as mercury, sulfur dioxide, carbon monoxide, mercury, selenium, and arsenic. These harmful substances not only cause acid rain but also are very harmful to humans as well. ADVANTAGES OF NATURAL GAS COMBINED CYCLE

    Everyone likes a good bar of gold or iron, right? Well you might want to think twice about it next time you go to buy a diamond or some coal for a fire. Greenpace.org says that “Underground mines, which provide the majority of the world’s coal, allow coal companies to extract deep coal deposits. About 40 percent of the world’s coal mines are the more damaging strip mines.” and the mines are damaging our environment more than it is helping it.

    1. Even though fracking reduces carbon emissions, it is still harmful to the environment. For example: water pollution/contamination. There can be accidental seeping of the chemicals (possibly carcinogenic) and can contaminate groundwater around the site due to bad practice (this imposes harm to both the ecosystem and people 's health).

    Over 20 percent of the energy in the United States comes from nuclear energy power plants. (Rinkesh, 2018) They so their best to get as much energy to the country as possible, but there are those out there who don’t agree with them. While there are downsides to nuclear energy, the pros vastly outweigh the cons. Nuclear power plants are a great way to get energy because they don’t let out much pollution, are very efficient, and are very safe.

    One of them is burning coal. The encyclopedia defines coal as a solid fossil fuel formed from the remains of land plants that were buried 300-400 years ago and exposed to intense heat and pressure over those millions of years. It is burned in power plants to generate electricity. Data says that 44% of the United States electricity comes from burning coal. The National Mining Association reported that in 2009, 55.4 percent of Maryland’s electricity came from it.

    Energy is a key factor in today's society, especially in Kentucky. Kentucky's main energy resource is coal, 91.8 percent of our energy comes from this resource but coal is nonrenewable, meaning that there is a limited amount of this type of fuel. Coal mining is also detrimental to the environment, people living and working in coal mining communities have a higher chance of getting lung cancer. with surface mining, this has been linked as a cause for poisoning local residences from the chemicals used in the mountaintop mining. there are still issues with the environment and natural wildlife in the surrounding areas of the coal mining as well.

    For instance, the stoves we use to cook our food run on gas, so does the heat water for our daily showers. In addition, to dry our clothes we use natural gas and for cars owners, we use gas or diesel to get from point a to point b. The U.S Energy Information Administration (EIA) states that natural gas has many qualities that make it an economical energy source. However, there are environmental issues associated with the production and use of natural gas (EIA, 2014).

    “Nuclear power will help provide the electricity that our growing economy needs without increasing emissions. This is truly an environmentally responsible source of energy.” Michael Burgess Prior to the introduction of nuclear energy, fossil fuel was thought to be the only available source in producing energy. Although fossil fuel, such as coal, petroleum, and natural gas, contains high energy value, it produces too many harmful byproducts that ultimately pollute our environment. With the rising concerns over global warming as more and more greenhouse gases accumulate in our Earth’s atmosphere, many voice such opinions that new alternative, yet sustainable method must be adopted to produce energy.

    Nuclear energy is something that we`ve all heard about. It carries risk and potential. When an atom (Uranium and Plutonium in nuclear power plants) is bombarded by neutrons, it can be split, causing fission. This fission releases more neutrons, which causes a chain reaction. Nuclear power plants use this use the heat that is created by fission to heat water that spins their turbines (“Nuclear Energy”).
