ExxonMobil sees global energy demand rising 25% up to 2040

Most growth in energy demand will occur in developing nations that are not part of the OECH, says Exxon

While demand will increase, this will be somewhat lessen by energy efficiency gains and increased use of renewable energy sources and lower carbon fuels, such as natural gas. These are expected to help reduce by half the carbon intensity of the global economy, ExxonMobil says. 

* In 2040, oil and natural gas are expected to make up nearly 60% of global supplies, while nuclear and renewables will be approaching 25%.
