Although global energy emissions increased 1.7 percent in 2018, without an increase in global natural gas consumption, “the increase in emissions would have been more than 15 percent greater.”
The IEA report says that global energy consumption increased in 2018 at nearly twice the average rate of growth since 2010, driven by a robust global economy and higher heating and cooling needs in some parts of the world. Demand for all fuels increased, led by natural gas, even as solar and wind posted double-digit growth. The report continues:
“Natural gas consumption grew by an estimated 4.6% in 2018, its largest increase since 2010 when gas demand bounced back from the global financial crisis…The switch from coal to gas accounted for over one-fifth of the rise in gas demand.”
Historic natural gas demand growth in the U.S. was mainly driven by power generation and buildings. A colder winter and hotter summer than average was responsible for around half of the extra gas demand in both sectors. The ongoing switch from coal to gas in power generation also contributed strongly to the growth, adding 18 bcm to gas demand. The share of gas in power generation hit an all-time record of 34%.
