World Energy Outlook 2016 IEA, March 16, 2017

Executive summary

In our main scenario, a 30% rise in global energy demand to 2040 means an increase in consump on for all modern fuels, but the global aggregates mask a mul tude of diverse trends and signi cant switching between fuels. Moreover, hundreds of millions of people are s ll le in 2040 without basic energy services. Globally, renewable energy – the subject of an in-depth focus in WEO-2016 – sees by far the fastest growth. Natural gas fares best among the fossil fuels, with consump on rising by 50%. Growth in oil demand slows over the projec on period, but tops 103 million barrels per day (mb/d) by 2040. Coal use is hit hard by environmental concerns and, a er the rapid expansion of recent years, growth essen ally grinds to a halt. The increase in nuclear output is spurred mainly by deployment in China.
