The paper presents data and results from the World Energy Outlook (WEO) 2014, published by the International Energy Agency (IEA). Over the period to 2040, total energy use is projected to grow by almost 40 per cent, while the share of fossil fuels in the energy mix falls. Nonetheless, these fossil fuels remain the dominant sources of energy, with oil, coal and gas each accounting for around one quarter of global energy needs by 2040. Increasingly, modern renewables are projected to replace fossil fuels, especially in the power sector. Around 93 per cent of the projected increased primary energy demand comes from non-OECD countries, with two-thirds coming from developing Asia, led by China. By 2025, China could account for almost a quarter of global energy use, doubling its share since the turn of the century. After 2025, India and other Asian countries surpass China as the main centres of energy demand growth. The IEA’s WEO 2014 concludes that even taking into account ambitious policy measures announced as of mid to late 2014, energy growth projections place the world on a path consistent with a long-term temperature increase of 3.6 degrees. Urgent action is required if the world’s energy systems are to be steered towards lower greenhouse gas emissions.
