By 2040, world population is expected to reach 9.1 billion, up from 7.3 billion today.
Global demand for energy is expected to climb about 25 percent by 2040, and would soar significantly higher – closer to a 100 percent increase – but for anticipated efficiency gains across the economy.
The challenge of providing the energy supplies that power the global economy is coupled with the need to do so in ways that reduce energy-related greenhouse gas emissions and mitigate the risk of climate change.
The global energy supply mix will shift over the next two-and-a-half decades.
With more people using energy to improve their lives, we estimate that global energy demand will be 25 percent higher in 2040 than it was in 2015.
