According to the latest figures of the IEA, in 2011, the total global energy demand grew slow only 3%, in which the global consumption coal yields increased 6,6% in the 12th year in a row, oil increased 1%, electricity output reduced 4% due to electricity production in countries under  Organization for Economic Cooperation and Development (OECD), club of richest countries in the world, was down 9.2%.

China became the largest coal importer in the world, while Indonesia became the largest coal exporter in the world, and surpassed Australia.

The oil demand in countries under OECD reduced 0.1% in 2011 because of sluggish economic growth. The amount of fuel consumption for automobiles took for 1/3 oil demand in OECD countries, and fell over 2% in 2011. It continued the trend of the strong decline since 2006.

Production of the globally natural gas consumption increased 2.1% in 2011, the lowest increase rate compared to the growth rate of 7.2% in 2010.

Gas consumption in OECD countries didn’t increase, amount of gas consumed in non-OECD countries took more than 50% of the global gas consumption.

Electricity production in OECD countries reduced 0.9% in 2011 because of the primarily decreased nuclear power.

Production of nuclear electricity in OECD countries decreased 9.2% in 2011 especially in Japan was down 65% and 23% in Germany, making the total full-OECD energy demand decreased 1.9% in 2011.

The IEA's statistics showed that the share of renewable energy sources of the total energy supplied the most important energy resources were up to 8.2% in OECD countries in 2011, higher than 7.8 % in 2010.

Wind energy was not only a source of the leading renewable energy in the electricity production but also the energy source had the highest speed up to 24% of all renewable energy sources.
