Can Alternative Energy Replace Fossil Fuels An Environmental Sciences Essay

Can Alternative skill interchange Fossil Fuels An Environmental Sciences EssayAt the beginning of the 21st century people extended to take care that dodo fuels are non renewable and they are consumed too quickly so people study that thither result not be a ancestor for incoming generations. Activists try to tell people to the highest degree the consequences of lack of heartiness in terms of economy or environment, so consciousness of the agency increases separately day with the help of activists. However, the public and likewise the government do not do anything to amend this situation. professor Emeritus of History, Geography, and Ameri shtup Studies at the University of Texas, Alfred W. Crosby asserts that Alternative sources of cypher can become a satisfactory transfigure for fossil fuels such as ember, oil, petroleum and diesel if we put as much effort and elan in the effort as we did in producing the first atomic bomb( alternate(a) efficacy.procon.org , para 3). However round opposites believe that resource efficiency cannot meet our need sufficiently. Also its hard to find a suitable speckle and the high technology to build this phase of structure. on that point are both pros and cons about using alternative energy which get below ones skins it difficult to find the roughly reliable way, save considering solely these various approaches, we can cease that fossil fuels are more harmful.There are many type of carbon based source which contain huge amount of energy such as coal, oil, natural tout. They are most usual 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 be go working condition is disaster but, people have to work this line because of unemployment. However coal mining have enormous dangerous for wellness because it cause lung disease. A lso cause deaths due to underground coal-mining accidents 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 take any precaution about disasters. Almost the same situation happens in Batman which has most of oil source in Turkey. Some worker suffer from similar riddle like health and condition, because they do not know their right in terms of both health and safety even if they are aware 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 apply fossil fuels for their own development without thought about its effect on people and the environment. They also do by pollution and damage to the environment but this careless behaviour has caused irreversible consequences such as nursery effect of burning fossil fuels traps the concen tration of carbon dioxide so this also increase heat as a result global warming occur. and then people should work together to establish non-governmental organizations to keep violation and unnecessary usage, because the humans supply will not be enough for the next generation. prof of Massachusetts Institute of Technology, M. S. Dresselhaus also emphasised that fossil fuels currently supply most of the gentlemans gentlemans energy needs, world militia of oil are about 1.61014 (11012barrels). World 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 un delicious their long-term 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 assess alternative sources of energy and determi ne what is scientifically attainable, 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 sheer, solar, geothermal, hydroelectric, and bio fuels are possible energy type which can replace fossil fuels. Like fossil fuels these energy types have some(prenominal) advantages and disadvantages. Wind and solar power cause no pollution and are renewable and also wind and solar power are free. The only 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 sunny live can change. Moreover geothermal energy built upon steam power so they drill holes in the steamy area and steam caused shoot up and drive turbines. Geothermal central should build correctly 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 element 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 pay attention 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 sun radiates 174 peta -watts (PW). Of this, about 30 percent is reected back to space, bit 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 satisfying year. However, settle that kind of energy source is very expensive and itsy-bitsy utopian. Nevertheless still reduce fossil fuels help prevent the pollution. According to one of the most comprehensive plans for future sustainable energy provision launched in June 2010 by Greenpeace and the European Renewable life force Council (EREC), a sustainable World Energy Outlook provides a detailed practical blueprint for cutting carbon emissions whil e achieving economic ontogenesis by 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 short(p) 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 possibility of least harm to the environment is still a risk. Therefore alternative energy must be encouraged by government and the public. other 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 reason 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 mean 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 easy 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 useful 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 arri ve at the conclusion that 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 benefit from it.Work Citedhttp//alternativeenergy.procon.orgDresselhaus, M.S., and I.L.
