Renewable capacity growth stalled in 2018

After nearly two decades of strong annual growth, renewables around the world added as much net capacity in 2018 as they did in 2017, an unexpected flattening of growth trends that raises concerns about meeting long-term climate goals.

Last year was the first time since 2001 that growth in renewable power capacity failed to increase year on year. New net capacity from solar PV, wind, hydro, bioenergy, and other renewable power sources increased by about 180 Gigawatts (GW) in 2018, the same as the previous year, according to the International Energy Agency’s latest data.

That’s only around 60% of the net additions needed each year to meet long-term climate goals.

Renewables have a major role to play in curbing global emissions. Renewable capacity additions need to grow by over 300 GW on average each year between 2018 and 2030 to reach the goals of the Paris Agreement, according to the IEA’s Sustainable Development Scenario (SDS).

But the IEA’s analysis shows the world is not doing enough. Last year, energy-related CO2 emissions rose by 1.7% to a historic high of 33 Gigatonnes. Despite a growth of 7% in renewables electricity generation, emissions from the power sector grew to record levels.

“The world cannot afford to press “pause” on the expansion of renewables and governments need to act quickly to correct this situation and enable a faster flow of new projects,” said Dr Fatih Birol, the IEA’s Executive Director.

“Thanks to rapidly declining costs, the competitiveness of renewables is no longer heavily tied to financial incentives. What they mainly need are stable policies supported by a long-term vision but also a focus on integrating renewables into power systems in a cost-effective and optimal way. Stop-and-go policies are particularly harmful to markets and jobs.”
