Fossil fuels like coal, petroleum, uranium, natural gases are non-renewable energy sources, which mean these resources cannot be re-made or regenerated. In contrast to that, renewable energy resources like hydroelectric energy, solar energy, wind energy, and geothermal energy do not deplete, or it will take a substantially long time to deplete them as it can be replenished by nature. Statistics has shown that there is an increase in the investment of renewable energy over the pass few years, in 2007 more than $100 billion was invested in renewable energy (Renewables 2007 Global Status Report 2007, p. 16). Even China which has overtaken the United States as the world’s leading producer of greenhouse gases (cited in Joseph Kahn and Jim Yardley 2007 p.1). is switching to renewable energy resources(Renewables 2007 Global Status Report 2007, p. 8). The main reason for the switch to renewable energy is because it is environmentally-friendly and it will not affects the balance of the ecosystem.
