Fundamentals of World Energy Use

Population growth has a direct relation to the growing energy demand of mankind. A major emphasis has been laid on the usage of various energy supplies from both renewable and nonrenewable energy sources to meet the global energy demand. The energy supply from burning renewable energy sources such as bioenergy, hydropower, and natural gas has accounted for clean release of the by-products and zero carbon emissions. On the other hand, large-scale energy supply from the combustion of fossil fuels forms the global energy system. Fossil fuels fulfill two-thirds of the world's energy consumption.
