The IEA's latest estimates for those without modern energy access, based on 2010 data wherever available, show that an estimated 1.265 billion people are without access to electricity - 50 million fewer than last year, but still 19% of the global population. An estimated 2.588 billion people - nearly 40 million fewer than 2009 - rely on the traditional use of biomass for cooking. There is no change in the fact that those without access to electricity are concentrated overwhelmingly in sub-Saharan Africa and developing Asia and that nearly two-thirds are concentrated in just ten countries.
