The world may consume 59% more energy in 2030 than it does now, with fossil fuels providing 85% of the increase, according to the "World Energy Outlook 2004" released by the International Energy Agency (IEA).
Under the IEA's "Reference Scenario," two-thirds of the new energy demand will be in the developing world, with China and India dominating the growth in demand. As a result, oil production will increase by 48%, coal production will increase by 59%, and natural gas production will double. Meanwhile, electricity generated from renewable energy will increase by a factor of six, mostly due to increases in wind and biomass power. Since the world's electrical demand will double in that timeframe, the percentage of power generated from renewable energy will increase from 2% today to 6% in 2030.
