Renewable power capacity stalls for 1st time since turn of millennium
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.
Since 2015, global solar PV’s exponential growth had been compensating for slower increases in wind and hydropower. But solar PV’s growth flattened in 2018, adding 97 GW of capacity and falling short of expectations it would surpass the symbolic 100 GW mark.
Despite slower solar PV growth, China accounted for almost 45% of the total capacity increase in renewable electricity last year. With new transmission lines and higher electricity demand, China’s wind additions picked up last year, but hydropower expansion continued to slow, maintaining a trend observed since 2013.
Capacity additions in the European Union, the second-largest market for renewables, saw a slight decline. Solar PV grew compared with the previous year, while wind additions slowed down. Policy transition challenges and changing renewable incentives resulted in slower growth of onshore wind in India and of solar PV in Japan.
Renewable capacity expansion accelerated in many emerging economies and developing countries in the Middle East, North Africa and parts of Asia, led by wind and solar PV as a result of rapid cost declines.
