Gas to overtake coal as world’s 2nd largest energy source by 2030: IEA

Natural gas is expected to overtake coal as the world’s second-largest energy source after an oil by 2030 due to a drive to cut air pollution and the rise in liquefied natural gas (LNG) use, the International Energy Agency (IEA) said on Tuesday.

The Paris-based IEA said in its World Energy Outlook 2018 that energy demand would grow by more than a quarter between 2017 and 2040 assuming more efficient use of energy – but would rise by twice that much without such improvements.

Global gas demand would increase by 1.6 per cent a year to 2040 and would be 45 per cent higher by then than today, it said.

The estimates are based on the IEA’s “New Policies Scenario” that takes into account legislation and policies to reduce emissions and fight climate change. They also assume more energy efficiencies in fuel use, buildings, and other factors.

“Natural gas is the fastest growing fossil fuel in the New Policies Scenario, overtaking coal by 2030 to become the second-largest source of energy after oil,” the report said. China, already the world’s biggest oil and coal importer, would soon become the largest importer of gas and net imports would approach the level of the European Union by 2040, the IEA said.

Although China is the world’s third-biggest user of natural gas behind the United States and Russia, it has to import about 40 percent of its needs as local production cannot keep pace.

Emerging economies in Asia would account for about half of total global gas demand growth and their share of LNG imports would double to 60 percent by 2040, the IEA report said.

Global electricity demand will grow 2.1 percent a year, mostly driven by rising use in developing economies. Electricity will account for a quarter of the energy used by end users such as consumers and industry by 2040, it said.

Coal and renewables will swap their positions in the power generation mix. The share of coal is forecast to fall from about 40 percent today to a quarter in 2040 while renewables would grow to just over 40 percent from a quarter now.
