ENERGY SCENARIO OF THE WORLD (PART-1)

• The world around us has changed significantly over the past 20 years. Technology has become one of the main drivers of economic and social development.
•  The rapid advancement of Information Technology (IT) all over the world has transformed not only the way we think, but also the way we act. All aspects of human life have been affected by IT and the Internet, in particular. 
• Needless to say that practically all technologies run on electricity and therefore the share of electricity is increasing rapidly, faster than Total Primary Energy Supply (TPES). 
• Population growth has always been and will remain one of the key drivers of energy demand, along with economic and social development. While global population has increased by over 1.5 billion over the past two decades, the overall rate of population growth has been slowing down. The number of people without access to commercial energy has reduced slightly, and the latest estimate from the World Bank indicates that it is 1.2 billion people. 
• The only renewable energy resources for which projections were made in 1993 were hydro power and biomass. The contribution of renewables was not very significant in those days, and the rest of the renewables were not taken into consideration individually, but combined into one group called Other Renewables. For comparability, the same resources are included under this heading for 2011. They are however, presented separately in the full World Energy Resources 2013 report.
