Renewable And Non Renewable Energy Sources Environmental Sciences Essay
Re naked as a jaybirdable And Non Renewable Energy Sources Environmental Sciences turn upWe back non use our feet to precedent our cars like the flinstones. So, how do cars relocation around? Energy what is vitality? aught is the ability to do work. whole living things need null to grow, plants use light from the sun to grow, in addition light is a type of expertness we use alone the time, we rush most of the light from the sun, but at night we make our consume light using a nonher heftiness source known as galvanicity. Energy makes things move, cars put out on the button stored in gasoline mainsheet boats be pushed by the energy in the wind. It takes energy to run our televisions, com effectuateers, and characterization games in the form of electricity, we use electricity all daylight long, it gives us light and warmth, it makes things operate. After a long day dont you feel as well as tired to move? Well you have ran out of energy, you need several(prenomin al) food to re give the sack. Imagine what your life would be without electricity?There atomic number 18 two main types of energy renewable and non-renewable, basically Most of the energy we use comes from dodo fuels, such(prenominal) as burn, indwelling gas and crude. uracil is another nonrenewable source, but it is not a fogey fuel. uranium is converted to a fuel and used in atomic precedent plants. Once these natural resources ar used up, they be gone forever. The growth of assembly these fuels can be harmful to the biomes from which they come. Fossil fuels are put through a process called combustion in order to catch energy. Combustion releases contaminant, such as snow monoxide and sulfur dioxide, which may open to acid rain and global warm. Other than Renewable sources of energy can be used over and over again. Renewable resources include solar energy, wind, geothermal energy, biomass and hydro spot. They generate much less pollution, both in gathering an d production, than nonrenewable sources. But it is believed that petroleum in particular go forth not be depleted as it is generated in the deep sedimentary basins til now if it will take thousands of years but it will be generated and petroleum will still be one of main and important sources of energy and the source upon which countries economies depend on, in the following report we will smack to identify different energy sources available in the introduction.Scientific desktopRenewable energy is defined () to be those energy source which do not deplete. They are basically natural sources of energy like sun, wind, -whereas nonrenrenewable energy sources renewable energy sources are the sources which when used will not be depleted from the world.Data resumeThe following section will demonstrate various examples from around the world to show energy sources uses and applications.

Fossil fuels formed millions of years ago, during the Carboniferous Period, from the remains of plants and animals. As the plants and animals that inhabited the swamps died, they were buried under sand and mud which stopped them from decaying. over time, more sediments covered the remains and pressure, together with heat, turned them into coal, oil and natural gas deposits.Today, fogey fuels are used in power station to generate electricity. Natural gas is also commonly used in homes to cook food and heat water, and compressed natural gas can power specially de sign-language(a) vehicles. rock oil is the main source of power for vehicles, in the form of petrol or diesel.74% of the UKs ele ctricity is generated from fossil fuels.Most of the worlds oil (13%) comes from Saudi Arabia.Russia is the main give awayr of natural gas, extracting virtually 22% of the total produced each year. The UK is 5th with 3.2%.China leads the way in coal production, mining 38% of the worlds coal.2-nuclear powerIn most electric power plants, water is heated and converted into steam, which drives a turbine-generator to produce electricity. Fossil-fueled power plants produce heat by burning coal, oil, or natural gas. In anuclear power plant, thefission of uranium atomsin the nuclear reactor provides the heat to produce steam for generating electricity.Several commercial reactor designs are currently in use in the United States. The most wide used design consists of a heavy steel pressure watercraft surrounding a reactor meat. Thereactor corecontains the uranium fuel, which is formed into cylindrical ceramic pellets and sealed in long metal tubes calledfuel rods. Thousands of fuel rod s form the reactor core. Heat is produced in a nuclear reactor when neutrons strike uranium atoms, causing them to split in a persisting chain answer.Control rods, which are made of a material such as boron that absorbs neutrons, are placed among the fuel assemblies.When the neutron-absorbing control rods are pulled out of the core, more neutrons become available for fission and the chain reaction speeds up, producing more heat. When they are inserted into the core, fewer neutrons are available for fission, and the chain reaction slows or stops, reducing the heat generated. Heat is removed from the reactor core area by water flowing through it in a closed pressurized loop. The heat is transferred to a second water loop through a heat exchanger. The water also serves to slow down, or support the neutrons which is necessary for sustaining the fission reactions. The second loop is kept at a lower pressure, allowing the water to labor and create steam, which is used to power the tu rbine-generator and produce electricity.Originally, nuclear energy was expected to be a uninfected and gilded source of energy. Nuclear fission does not produce atmospheric pollution or greenhouse gases and it proponents expected that nuclear energy would be cheaper and cash in ones chips longer than fossil fuels. Unfortunately, because of construction cost overruns, poor management, and numerous regulations, nuclear power ended up being much more pricy than predicted. The nuclear accidents at Three Mile Island in Pennsylvania and the Chernobyl Nuclear Plant in the Ukraine raised concerns about the prophylactic of nuclear power. Furthermore, the paradox of safely disposing spent nuclear fuel remains unresolved. The United States has not built a new nuclear facility in over twenty years, but with continued energy c beginnings across the country that note may change.19% of the UKs electricity comes from nuclear power(http//cnx.org/content/m16730/ current/)3-CoalAt the present r ate of use, the known coal supplies will furthermostly about 300 years and oil may not last for more than about 50 years. A great deal of fossil fuel is burnt in power stations. The coal is burnt to boil water which in turn produces steam. The steam drives the fans of a large turbine (a rattling(prenominal) big dynamo) which then generates electricity. The electric current is transported to our houses by large power cables. The whole process is an example of how energy is transformed from chemical energy to heat energy tokinetic energy and then finally to galvanising energy.Figure (1)Problems with non-renewable energyThe main source of energy today is fossil fuel. However, there are two main problems associated with this type of fuel the confine availability of fossil fuels and climate change. There are also safety concerns linked to the use of nuclear power and the radiation that is produced.Limited availability of fossil fuelsFossil fuels are non-renewable sources of energy , so they could one day run out. Alternative sources of energy are needed. As supplies decrease, the cost of buying fossil fuels may increase causing economic problems as well mode changeWhen fossil fuels are burnt they produce the gas carbon dioxide (CO2). Carbon dioxide is known as a greenhouse gas because it traps heat from the sun, much like the glass in a greenhouse, preventing it from escaping out of the Earths aureole into space. Greenhouse gases are found naturally in the atmosphere and they are essential for keeping the Earth warm. However, through the activities of humans, mainly as a result of burning fossil fuels, the amount of these gases in the atmosphere is increasing. As a result, global warming is occurring as the temperature of the Earth rises.Global warming is leading to climate change.Polar ice-caps are melting, causing a rise in sea level around the world.Rainfall patterns are changing and extreme weather events, such as hurricanes and droughts, are more ev eryday in some parts of the world.The UK is one of 170 countries that have signed an agreement called the Kyoto Protocol, which sets out targets for reducing CO2 emissions.There are also some environmental problems with fossil fuels such asoil SpillsOil has to be transported from oil fields to where it is needed. Oil tankers, which can carry many tens of thousands of tons of oil, are regularly used to transport the oil. Unfortunately, accidents can and do happen and the oil spills that result from these accidents have caused some major environmental headaches. Local birds, fish and animals such as sea otters and seals are very vulnerable to oil spills. Although the immediate damage can often calculate horrific, with the help of careful human clean-up operations and with natural processes that help clean the environment, the marine ecosystem can usually recover well.Figure(2)Acid RainWhen coal burns, it produces gases like carbon dioxide, which are then released into the atmosphere . Other harmful gases produced by coal burning are sulphur dioxide and some nitrogen oxides. These dismiss in the water in the atmosphere to create weak solutions of sulfuric acid and nitric acid, which can then return to Earth as acid rain. Unfortunately many trees and plants cannot thrive when the water they need is bitter like this and large areas of forest can be affected. In the cudgel cases the vegetation may be killed.conclusionIn the end we essential understand how energy is something we can not make do without as without energy there is no life. As for some harmful energy sources then we have to find and start looking for alternative energy sources which are clean and non harmful, we should also start to depend on renewable energy sources as we know that they will not be all depleted in the future.
