The U.S. Energy Information Administration (EIA) has released its International Energy Outlook 2011 (IEO2011) report, which shows an average 2.3% annual increase in global demand for electricity through 2035.
This growth, which will be most pronounced in developing nations, ultimately reflects a net global electricity generation total of 25.5 trillion kWh in 2020 and 35.2 trillion kWh in 2035. These figures compare to a total of 19.1 trillion kWh in 2008, according to the EIA.
Among the study's most compelling findings is that renewable energy is projected to be the fastest growing source of electricity generation globally. Total generation from hydroelectric, wind, geothermal and other renewable generation resources will increase by 3.1% annually through 2035, and renewable energy's share of global electricity generation will grow from 19% in 2008 to 23% in 2035.
