Energy demand worldwide grew by 2.3% last year, its fastest pace this decade, an exceptional performance driven by a robust global economy and stronger heating and cooling needs in some regions. Natural gas emerged as the fuel of choice, posting the biggest gains and accounting for 45% of the rise in energy consumption. Gas demand growth was especially strong in the United States and China.
Demand for all fuels increased, with fossil fuels meeting nearly 70% of the growth for the second year running. Solar and wind generation grew at double-digit pace, with solar alone increasing by 31%. Still, that was not fast enough to meet higher electricity demand around the world that also drove up coal use.
As a result, global energy-related CO2 emissions rose by 1.7% to 33 Gigatonnes (Gt) in 2018. Coal use in power generation alone surpassed 10 Gt, accounting for a third of the total increase. Most of that came from a young fleet of coal power plants in developing Asia. The majority of coal-fired generation capacity today is found in Asia, with 12-year-old plants on average, decades short of average lifetimes of around 50 years.
