2009. Although the use of biomass is still the dominant technology (and includes the use of “traditional” biomass with low efficiency for heating and cooking), growth in solar heating, and to a lesser extent geothermal heating technologies, has been strong, with an overall growth rate of nearly 12% between 2005 and 2009. Growth was particularly driven by rapid increases in solar heating in China." • "The production and use of biofuels have been growing rapidly, and in 2009 they provided 53.7 Mtoe, equivalent to some 3% of road transport fuels (or 2% of all transport fuels). The biofuels sector has been growing very rapidly (26% CAGR in 2005-09). Biofuels production and consumption are still concentrated in Brazil, the United States and in the European Union. The main centres for ethanol production and consumption are the United States and Brazil, while Europe produces and consumes mainly biodiesel. The remaining markets in other regions and the rest of the world account for only 6% of total production and for 3.3% of consumption. Trade in biofuels plays a limited, yet increasingly important role." See also The Third Industrial Revolution The Clean Tech Revolution List of books about renewable energy Mark Z.
