Growth decelerated for all regions and for all fuels. Oil remains the world’s leading fuel, accounting for 33.1% of global energy consumption, but this figure is the lowest share on record. Coal’s market share of 30.3% was the highest since 1969. Courtesy of BP Statistical Review of World Energy 2012, BP p.l.c.

Europe & Eurasia is the leading region for consumption of natural gas, nuclear power, and renewables. Coal is the dominant fuel in the Asia Pacific region; natural gas is dominant in Europe & Eurasia, and oil is dominant in all other regions.

Some Final Thoughts • National energy systems are incredibly diverse, with many drivers of diversity – not just resources • Growth in energy use, CO2 likely to come mainly from developing nations, esp. China • If the world got rich using OECD/US models, huge increases in energy, CO2 emissions • Finding and moving to another growth path will be a great challenge by any standard 36 MIT OpenCourseWare http://ocw.mit.edu 15.031J / 14.43J / 21A.341J / 11.161J Energy Decisions, Markets, and Policies Spring 2012 For information about citing these materials or our Terms of Use, visit: http://ocw.mit.edu/terms. 37
