The US Energy Information Administration has published its International Energy Outlook 2013 (IEO2013) which projects that world energy consumption will grow by 56 percent between
2010 and 2040 with total world energy use rising from 524 quadrillion British Thermal Units (Btu) in 2010 to 630 quadrillion Btu in 2020 and 820 quadrillion Btu in 2040. Much of this growth occurs in countries outside the Organisation for Economic Cooperation and Development (OECD) where demand is driven by strong, long-term economic growth. Energy use in non-OECD countries rises by 90 percent compared to 17 percent in the OECD.
The world's fastest-growing energy sources are renewable energy and nuclear with each growing by 2.5 percent per year. Nevertheless, fossil fuels continue to supply almost 80 percent of global energy use through 2040. Of this, natural gas is the fastest growing fossil fuel source.
The UK's green goods and services market has grown by almost 5 percent to more than £128 billion over the 2011/12 period. The UK now accounts for a 3.7 per cent share of the global Low Carbon
Environmental Goods and Services (LCEGS) market, which is valued at
£3.4tr and has grown by 3.8 per cent since last year's figures were issued. The report confirms that alternative fuels, building technologies, and
wind power are by far the largest sectors in terms of both global and UK
LCEGS sales, where they accounted for £19.2bn, £15.4bn, and £15.1bn
