Key features in electricity and CO2: world
F Total electricity (and heat1) output grew by 56% between 1990 and 2008, with a marked reduction in growth in the year 2008 (1.5% against 3.3% over the previous decade).
F OECD North America, Europe and China account for 60.5% of global power output in 2008. These three regions also account for 61.6% of electricity-related CO2 emissions in that year, with China as the first emitter.
F China recorded the fastest growth, at 11.3% per annum between 1998 and 2008, followed by the Middle East region, with 6.5%. Other regions with fast growing electricity-related CO2 emissions include India and the rest of Asia, driven by economic growth and reliance on coal and gas in electricity generation.
F The CO2 emissions intensity of electricity and heat generation has grown by 6% since 1990, to 0.5 tonnes of CO2 emitted per megawatt-hour produced (tCO^/MWh). Global CO2 emissions from combined electricity and heat production grew by 64.9% over the same period.
F The share of electricity produced from non-fossil fuels has been decreasing slowly since 1995, in spite of growth in nuclear, hydro, and other renewables in the electricity mix.
F Non-hydro renewables are the fastest growing source of electricity; coal dominates global output with 41% of the total. Gas has gained market shares over oil, which supplied only 5.5% of the global production of electricity in 2008.
F Industry is the largest consumer of electricity, with about 42% of total final consumption in 2008, against 45% in 1990. Its share has been increasing again since 2003 as the result of industrial growth in Asia.
F Wind capacity witnessed extraordinary growth in the last couple of decades, with 114 GW installed in 2000-2010 compared to 9 GW in the previous decade. Wind power generation has become the largest non-hydro renewable source since 2007, ahead of biofuels. Coal and gas have nonetheless largely dominated capacity additions since 1990.
