Suggest two reasons why resources of renewable energy have become more important in many countries.

Firstly, increasing population size can cause increased energy demands. This means that alternatives to non-renewable energy must be found as fossil fuels can no longer meet such demands, thus causing increased need for renawable energy sources. For example, in India, nuclear energy has been used increasingly to meet population growth.Secondly, negative environmental impacts caused by non-renewable energy sources has caused governments to develop renewable energy resources. In China, for example, increased greenhouse emissons, caused by burning sulfur-rich coal, has resulted in the growth of their nuclear energy sector.
