Electricity from Worldwide Energy Sources

The aim of this article is to investigate electricity production from energy sources. Electricity, which is a secondary energy source, can be generated from the conversion of other sources of energy, such as coal, natural gas, oil, nuclear power, and other natural sources, which are called primary sources. Much of the growth in new electricity demand is expected to come from the countries of the developing world. At present, developing countries, with more than 75% of the world's population, account for only about one-third of the world's electricity consumption. World net electricity consumption is expected nearly double to over the next two decades. Total demand for electricity is projected to increase on average by 2.3% per year, from 13,290 billion kWh in 2001 to 23,072 billion kWh in 2025. The mix of primary fuels used to generate electricity has changed a great deal over the past three decades on a worldwide basis. Renewables are the third largest contributor to global electricity production.
