It is also cheaper than coal or burning gas. Also the wind energy is a moral energy because it doesn’t have to kill any living thing like plants or animals to produce electricity and it uses natural wind to convert electricity, so it is better than digging in the earth to get fossil fuels and burning to get
This is evident in Figure … where an equivalent amount of energy is given, the nuclear energy is able to sustain power up to years, where normal fossil fuel can only sustain up to a few days. Although there are debates that the life span of nuclear power sources such as Uranium is low and is comparable to oil, this do not pose a threat as nuclear energy can be recycled. In addition, nuclear power plant only emits hot water into the environment which makes it environmental friendly. In fact, little or almost no carbon dioxide is being released into the atmosphere. The little amount of carbon dioxide is produced because of the mining and construction of the power plant, however the amount released is not comparable to that of other fossil fuel.
Geothermal Energy “There is an urgent need to stop subsidizing the fossil fuel industry dramatically reduce wasted energy and significantly shift our power supplies” (McKibben). Geothermal energy is the heat from the earth.Resources of geothermal energy range from the shallow ground to hot water and rock beneath the earth’s surface.people can capture this energy through power plants,which use heat from deep inside the earth to generate steam to make electricity.A geothermal system is three to four times more efficent than the most efficent ordinary system.Although the sun does heat on the earth´s surface heat from inside the earth is not caused by the sun.Geothermal energy is positive because It´s good,and it helps the economy. However,Geothermal
What is geothermal energy? : Geothermal energy is thermal (heat) energy that is stored, generated and emanated from the Earth’s core to the Earth’s crust. How is it generated? : The earth core generates geothermal energy through the natural decay of radioactive materials such as Uranium and Potassium. This heat energy is mostly found within magma, which exists below the Earth’s crust.
Geothermal power plants use the heat radiating from the center of the Earth to generate electricity and, in Iceland, to heat the entire cities. (National Energy Authority of Iceland (NEA).com) In many parts of the world, Geo-Thermal energy is under-utilized and should be promoted since it is pollution free, renewable, and capable of supplying electricity to millions of families. Exactly how does it work? How do we extract the geothermal energy from the underground? Geo-Thermal energy is thermal
Emily Hois states solar panels are quickly becoming far more efficient than fracking and is one of the best alternatives. • Fracking is cheaper than solar panels. • However, in the long run fracking will become more expensive (Woodford, 2016). • Solar panels are cleaner and saves more money than fracking in the long run. 2.
If the fossil fuels would start depleting, this geothermal energy will be one of the cheapest source of power generation. The advantages of using geothermal energy is that is significantly cost saving. Geothermal energy involves low running costs since it saves 80% costs over fossil fuels and no fuel is used to generate the power. Since no fuel is require so costs for purchasing, transporting and cleaning up plants is quite low. Furthermore, geothermal energy does not create any pollution which contributes to a clean environment.
Nuclear Energy Nuclear energy is a strong force that holds together the nucleus in an atom. To release this energy in order to produce electricity, scientist use the processes called nuclear fusion and nuclear fission. Once the energy is released, it will change into radiation which is a form of energy. Before nuclear energy was generated, we use fossil fuel to produce electricity. However, fossil fuels such as coal and oil contributes detrimental air pollution.
The advantages of using Nuclear power plants: • Free from CO2 : One of the major advantages of using nuclear power plants is that, it is free from carbon-di-oxide emissions. Most of the conventional methods of generating electricity include the usage of non- renewable resources like coal which generates CO2 upon usage. • Very efficient source of energy: The energy produced by the fission of an atom of uranium or plutonium or any other element used in the process of nuclear fission for generating energy, I almost 10 million times the amount of energy produced by combustion of a single atom of carbon in coal. It also doesn’t result in the depletion of fossil fuel reserves. Hence one can obviously see the efficiency and the effectiveness of using nuclear power plants for producing heat and
Types of fossil fuels energy: Coal Coal provides around 28% of our energy Oil Oil provides 40%of our energy Crude oil (called "petroleum") It is easier to get out of the ground than coal, as it can flow along pipes. This also makes it cheaper to transport Natural gas It provides around 20% of the world 's consumption of energy o Advantages of Using Fossil Fuels Very large amounts of electricity can be generated in one place using coal, fairly cheaply. Transporting oil and gas to the power stations is easy. Gas-fired power stations are very efficient. A fossil-fuelled power station can be built almost anywhere o Disadvantages of Using Fossil Fuels Basically, the main drawback of fossil fuels is pollution.
