The new World Energy Outlook 2014 (WEO-2014) released by the International Energy Agency (IEA) forecasts that global primary energy consumption will increase by 37% between 2013 and 2040. Global energy demand should rise by 1%/year after 2025, a much slower rate than the average +2%/year over the last two decades ; this slowdown will be linked to price and policy effects, with structural changes in the service sector and in industry. Energy consumption should remain flat in Europe, North America, Japan and South Korea, while Asian consumption will continue to increase rapidly to 60% of the global demand. China should become the largest oil consuming country in around 2030, overtaking the United States where oil consumption should decline (respectively 480 Mt and 738 Mt of oil consumed in 2013). By 2040, the global energy mix should be divided into four almost-equal parts (oil, gas, coal and low-carbon energy sources). Gas demand will increase by more than 50% by 2040, while coal and oil demand will "only" increase by 15% by this date.
