Energy plays a central role in the economic development of a country. As the global economy expands, there will be a corresponding increase in the amount of energy demanded, particularly fossil fuels. One of the consequences of the greater use of energy (by burning fossil fuels) is the higher level of emission of greenhouse gases such as carbon dioxide, which is the biggest source of global warming. Meanwhile, oil and gas prices will continue to trend upwards because of persisting political uncertainties in the West Asia and the voracious appetites of China and India. Our own oil reserves are expected to run dry in 10 years.
