Losing polluting natural resource is one of the most serious problems that people concerned during the 21st century. Scientists have found that traditional sources like fossil fuels are threatening people’s lives as well as the environment. Due to this, some countries have started their plans to harness, renewable energy and achieved satisfactory success. For a decade, the majority of countries in Europe have proved that used alternative source can reduce the environment pollution and the benefit of using alternative source is optimistic. In my opinion, the alternative source can reduce the environment pollution and how to harness that resource effectively is an important issue that I will discuss above.
There are various energy consider to be harmful to nature, such as oil and other fossil fuels, that have been abandoned by people now. In the past years, people drove gasoline cars which cause ever-increasing emissions and harmful gases that have negative effect to the ozonosphere. Besides, these traditional sources in earth have reduced sharply by fossil fuel used. Therefore, fossil fuels used mast be replaced by alternative resource. Alternative resource, which found by experts, is encouraged to solve the environment polluted problems. Firstly, there are many form of renewable source, like the solar system, biogas, wind turbines, nuclear power and hydropower energy. These sources can be recycled and they are gentle to the environment. Secondly, it is easy to get these alternative sources. In Kristiansand, people develop fuel from a variety sources: from an old landfill and sewage ponds, as well as wood waste from flooring factories and tree pruning.

Moreover, the benefit of using the renewable resources can be counted. Firstly, the renewable source can be used widely. Biogas can be used into heating, electrocuting and
