Alternative Sources of Energy

In present day people all around the world have used many energy sources. For instance, cars have to use much fossil fuel energy. Coal and natural gas also have been used too much to heat homes and businesses even during the winter (Adapted from Rosenthal, E. , 2010, December 11). As this information, ‘finding alternative energy sources is one of the major projects of this century in all countries because the world is running out of the natural resources’ (Edited extracts from authentic student material). ‘Humans have used much of earth’s resources, and the resulting environmental impacts are global. There is strong evidence that society is approaching a transition and the patterns o the 20th-century consumption and growth cannot be sustained. The interconnected forces leading to this transition include energy scarcity, human impacts on the biosphere, climate change, and population growth’ (Adapted from Day, J.W., Hall, C.A., Ecology in Times of Scarcity). Moreover, coal and oil create emissions when burned, so that it pollutes the atmosphere or the environment. Furthermore, the earth nowadays faces great environmental disaster unless global warming is controlled. From this result, not only governments but also other authorities should try to find the most effective way to develop many alternative sources of energy, and even try to discover some new kinds of energy sources instead. This essay will focus on some specific sources of energy and the suitability between countries and any sources.

There are several types of alternative sources of energy. For example, some experts claim that the technology and safety aspects of some sources of energy such as solar power, wind turbines, nuclear power and hydropower needs to be improved. The first alternative energy source might be solar energy because it is renewable energy that can be collected in everyday life. Although this source of energy is very easy to find and collect, the cost of the equipment required to convert solar power into electricity is quite high. It may be that this equipment is not yet produced on a large enough scale. Therefore, there are not many countries using solar energy for main energy purposes. Moreover, technologies are currently not expert enough to use the solar energy effectively. However, this source of energy is predicted to be the most valuable and renewable source in the future.

The second interesting source might be biogas. The cost of this gas is obviously low when compare with fossil fuel. In addition, the consumption of petrol is now reaching the stage where supplies will soon run out. Searching for new fuel energy is essential because using too much petrol is going to be a cause of environmental problems, especially geological problems. Also, the price of fossil energy is a considerable factor for changing to use natural gas instead. According to the research of many environmental institutes from many developed countries, if people could use biogas instead of fossil fuel, they would economize many expenses and also could automatically decrease the use of fossil fuel, that means the earth might be automatically recovered. From the point of suitability, not every alternative source of energy can be used effectively in each country in the world, only some of these energy sources will be appropriate. There are many factors to consider in determining a suitable source of energy such as the environment, weather, topography, country’s location, etc. For example, solar energy is absolutely appropriate in Middle-eastern countries because the countries’ location are located in the warm area, where they have to face to the sun light very much. As this point, it is obviously worthwhile to create some organization for applying or adapting to use solar energy effectively. The government may seriously provide funding to develop some tools and improve some professional staff to get the most profit from using this kind of energy. In conclusion, it is obviously true that people have used most non-renewable energy and now these sources of energy are running out. Therefore, people should encourage themselves trying to use renewable sources of energy effectively. In addition, governments should carry out systematic research into the method of using different sources of energy to use this energy efficiently and also concern about the balance between profits and disadvantages from using those sources of energy.
