The competition between nations largely depends on who can have a head start in energy after Industrial Revolution, as many mainstream energy sources are not renewable. Some people believe that traditional fuels, namely coal, oil, and gas, are the main sources rather than alternative sources like wind energy and solar energy. In my opinion, alternative sources of energy should be encouraged to utilize throughout the world.
Human beings’ use of energy in fossil fuels has had a long history and already gained popularity in most countries. Nonetheless, those traditional resources are exhaustible and will dry up in a foreseeable future. Alternative ways should be found for a sustainable future.
There are mainly two benefits of using alternative resource: Firstly, most new energies are green, i.e. environmental friendly, and using alternative sources reduce the environmental pollution.. Secondly, alternative sources of energy are regarded as relatively more sustainable, and are more likely to meet the increasing demands of social and cultural development in modern society. It is often considered, however, that using alternative sources of energy such as nuclear energy is a quite dangerous thing for human beings and our planet. Some other alternative sources of energy like wind energy and solar energy are not quite effective for the sake of huge cost.
In summary, the use of the alternative sources can accelerate social development and push the whole world forward rapidly, which does no harm to the environment and has high effectiveness. As technology advances day by day, it is hopeful that all the countries can use green energy at a low cost.
