The U.S. Energy Information Administration (EIA) projects that world energy consumption will grow by 28% between 2015 and 2040. Most of this growth is expected to come from countries that are not in the Organization for Economic Cooperation and Development (OECD), and especially in countries where demand is driven by strong economic growth, particularly in Asia. Non-OECD Asia (which includes China and India) accounts for more than 60% of the world's total increase in energy consumption from 2015 through 2040.
Through 2040, the EIA projects increased world consumption of marketed energy from all fuel sources, except for coal demand, which is projected to remain essentially flat. Renewables are expected to be the fastest-growing energy source, with consumption increasing by an average 2.3% per year between 2015 and 2040. The world’s second fastest-growing source of energy is projected to be nuclear power, with consumption increasing by 1.5% per year over that period.
