Can Alternative Energy Replace Fossil Fuels An Environmental Sciences Essay

Can election Energy Replace Fossil Fuels An Environmental Sciences EssayAt the beginning of the 21st century people started to realize that fogy fuels are not renewable and they are consumed too quickly so people deal that there lead not be a source for proximo generations. Activists try to tell people well-nigh the consequences of lack of vigor in call of economy or environment, so consciousness of the situation increases each day with the avail of activists. However, the public and also the government do not do anything to purify this situation. Professor Emeritus of History, Geography, and Ameri wad Studies at the University of Texas, Alfred W. Crosby asserts that Alternative sources of strength can become a satisfactory substitute for fossil fuels such as coal, oil, crude oil and diesel if we put as much effort and genius in the effort as we did in producing the first atomic bomb(alternative vitality.procon.org , para 3). However most others believe that alternative button cannot meet our need sufficiently. analogously its hard to find a suitable place and the high technology to build this resistant of structure. There are both pros and cons about using alternative energy which makes it difficult to find the most reliable way, however considering all these various approaches, we can conclude that fossil fuels are more harmful.There are some(prenominal) type of carbon based source which contain huge amount of energy such as coal, oil, natural gas. They are most common source to create energy. Especially in Turkey almost all energy comes from fossil fuels (%99.6). There are some specific places to produce such as Zonguldak for coal or Batman for oil. Underground coal mining sector very taught beca subroutine working(a) condition is disaster just, people hit to work this job because of unemployment. However coal mining have enormous dangerous for health because it cause lung disease. Also cause deaths due to underground coal-mining accident s have been recorded officially since 1941, and a total of 3094 deaths were reported between 1941 and 2003(Kucuker,1). Although this kind of evidence, both government and companies not retire any precaution about disasters. Almost the same situation happens in Batman which has most of oil source in Turkey. Some worker suffer from similar problem like health and condition, because they do not know their right in terms of both health and safety even if they are cognizant of their right companies employ worker on daily-bases so they can not seek their right consequently companies exploit worker easily.In the beginning of industrial age, countries used fossil fuels for their own development without thought about its upshot on people and the environment. They also ignored pollution and butchage to the environment but this careless behaviour has caused irreversible consequences such as greenhouse effect of burning fossil fuels traps the concentration of carbon dioxide so this also incr ease soup up as a result global warming occur. Therefore people should work together to establish non-governmental organizations to prevent violation and unnecessary usage, because the world fork over will not be enough for the next generation. Professor of Massachusetts Institute of Technology, M. S. Dresselhaus also emphasised that fossil fuels currently try most of the worlds energy needs, world reserves of oil are about 1.61014 (11012barrels). domain of a function consumption is about 1.21010a day. World reserves of natural gas are about 1.41014m3 gross production of gas is about 2.41012m3per year. World coal reserves are about 9.11011tonnes annual consumption is about 4.5109tonnes per year. However unacceptable their semipermanent consequence, he assert that the supplies are likely to remain adequate for the next few generations. Scientists and policy makers must make use of this period of grace to evaluate alternative sources of energy and determine what is scientifically possible, environmentally acceptable and technologically promising. Briefly fossil fuels such as coal, oil, natural gas, nuclear power supply most of the worlds energy needs in today world but they are not adequate for future generation without alternative energy.The world has many alternative energy sources such as wind, solar, geothermal, hydroelectric, and bio fuels are possible energy type which can replace fossil fuels. Like fossil fuels these energy types have several advantages and disadvantages. Wind and solar power cause no pollution and are renewable and also wind and solar power are free. The just now cost of solar and wind power is the installation and construction of the structure. Nevertheless, both wind and solar energy is inconsistent. It means wind intensity or rejoiced weather can change. Moreover geothermal energy built upon steam power so they drill holes in the steamy area and steam caused commit up and drive turbines. Geothermal central should build correc tly otherwise harmful gases and mineral can be released. Furthermore, hydroelectric central work with the help of accumulation of water so energy production is constant. However construction of dam is very expensive and sometimes especially in Turkey dam can damage historical place like Hasankeyf in the east of Turkey. Lastly like wind and solar power bio fuels is renewable. Ethanol is the main component of creating energy which is made from corn. It decreases the usage of gas but cost of conversion very expensive.In addition, Some countries realize the variety of alternative energy and manufacture prudence to these. Spain and Germany are very serious about creating alternative energy. They use many kind of alternative energy but lost of countries just use hydroelectrical energy in the name of alternative energy. However they do not realize that for example solar energy more powerful than hydroelectrical energy. Dieter Eissel assert that the insolate radiates 174 peta-watts (PW) . Of this, about 30 percent is reected back to space, while the rest is absorbed by atmosphere, clouds, oceans and land masses. The total volume of radiation absorbed by oceans and lands reaches up to 89 PW. Therefore, solar energy can provide 2,850 times more energy than current world demand. In comparison, the multiple for hydro power is 3, 5 for geothermal, 20 for biomass, and 200 for wind energy (Fischedick, 2000). This means that all nations need the solar radiation of just one day to meet their energy demands for a whole year. However, settle that kind of energy source is very expensive and little utopian. Nevertheless still reducing fossil fuels help prevent the pollution. jibe to one of the most comprehensive plans for future sustainable energy provision launched in June 2010 by Greenpeace and the European Renewable Energy Council (EREC), a sustainable World Energy Outlook provides a detailed practical blueprint for cutting carbon emissions while achieving economic growth b y replacing fossil fuels with renewable energy and energy efficiency (Eissel, 4).Also, there are some kinds of energy types which are related to fossil fuels but not that much harm such as natural gas and nuclear power. Natural gas release methane gas instead of carbon dioxide and methane gas does not cause greenhouse effect it increases the amount of natural gas reserves a little bit higher than fossil fuels. Nuclear power creates a huge amount of energy however risk also very high because if plants accidentally release something its damage may be catasrophic. In the end although fossil fuels have the scuttle of least harm to the environment is still a risk. Therefore alternative energy must be encouraged by government and the public. Otherwise countries will start to fight each other because of lack of resource of fossil fuel in fact they already start to fight as resource become limited and countries may occupy an oil-rich country under the name of peace or some unethical reaso n to take control of oil-reserves.On the other hand, some people claim that the world has enough fossil fuel supplies for at least 2-3 decades. They think that this issue not of great urgency. At the same time they believe alternative energy is not sufficient and enough to meet peoples needs. To exemplify, gas is much more efficient than electrical energy and also filling the cars petrol tank quicker than charging an electrical car. Critics also state that wind power or solar power is not well-situated to construct everywhere. They can only be built in a suitable place to be efficient. For instance wind turbinesmust be built in a windy area to create energy, this means where wind turbines can be constructed is a little restricted. Likewise solar energy is effective in countries which have many hours of direct sunlight. In this situations, as the cost of construction increase also the efficiency decrease.Taking all these points into consideration, we can convey at the conclusion th at alternative energy should be a convenient energy source for future generation, because there is no other option for future generation nobody can claim that fossil fuels will last forever, this generation should regulate the usage alternative energy and also pay attention to the environment. Otherwise fossil fuel become most valuable things in the world and lots of people not allow or afford to eudaimonia from it.Work Citedhttp//alternativeenergy.procon.orgDresselhaus, M.S., and I.L.
