But it isn’t fast enough to slash humanity’s greenhouse gas emissions and get global warming under control, the agency concludes in its 810-page annual World Energy Outlook.

The report estimates that the energy policies countries now have on their books could cause global greenhouse gas emissions to continue rising for the next 20 years as the world’s appetite for energy keeps surging. Use of fossil fuels, particularly natural gas, keeps growing.

The upside: Renewables such as wind, solar and hydropower will surpass coal as the world’s dominant source of electricity by 2030. And the cost of offshore wind power is falling fast, making it an increasingly attractive option for some countries.

The downside: Even as electric car purchases accelerate, a growing number of people in the U.S., Europe, China and India are buying larger S.U.V.s. In 2000, just 18 percent of passenger vehicles sold worldwide were S.U.V.s. Today, it’s 42 percent.

Quotable: “Without new policies in place, the world will miss its climate goals by a very large margin,” said Fatih Birol, the energy agency’s executive director.
