Energy is essential to people's lives in that all activities related to human need it. Since 1980s, To keep our sources of energy from being limited, many countries are striving to find any other alternatives from nature. Some people say that we still can not affort to attain enough amount of renewable sources of energy. However I definetely believe that fossil fuels will be replaced by renewable ones quickly than the pessimists' thoughts because of the development of technologies and the environment-friendly atmosphere.
Most of all, techonologies related to obtaining energy have developed rapidly. Each governments in many nations worried the situation that the present energy sources would run out of in a close time. So hansome sum of financial support have been poured in researching and extracting renewable sources of energy since 1980s. Obama, the president of United States of America promised that he will make it possible to replace nearly all fossil fuels with renewable sources from nature until 2020. Not only him, but many governments set their first priority of policies to the development of energy techonologies. Therefore, with these efforts, we can use renewable sources more fastly than we expected.
On top of that, people's concerns for environment promote the use of renewable sources. Unlike the past when people considered the industrial development as the most important thing, they changed their priorities. Many scientists and NGOs have warned pollution showing lots of evidence like the hole of ozon layer to people. Due to this continuous infusion, people have begun to care about nature. And companies which manafactured cars, electronic products and so on, can not help with investing in making more environment-friendly produts even if it costs much money. For example, the Samsung Economics Research Institution recommended companies that they pour money to invent envorionment-friendly products and renovate the manufacturing processes that do not have a negative impact on environment. Thus, also in the area of energy resources, renewable energy is necessary to make clean environment.
In brief, it will not take long time to exploit natural elements as main sources of energy. Because our technologies are improved quickly and people prefer envoriment-friendly sources to fossil fuels for their environment. In short, it is only the matter of time. |
