International Energy Agency has announced that as per its latest data, the 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. Reaching only 60 percent of the net additions needed every year to meet long-term climate goals.
Renewables have a key 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 study shows the world is not doing enough. Last year, energy-related CO2 emissions rose by 1.7% to a significant high of 33 Gigatonnes. Despite 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 faster flow of new projects,” said 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.”
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. The main reason was a sudden change in China’s solar PV incentives to curb costs and address grid integration challenges to achieve more sustainable PV expansion. Moreover, lower wind additions in the European Union and India also contributed to stalling renewable capacity growth in 2018.
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.
“These 2018 data are deeply worrying, but smart and determined policies can get renewable capacity back on an upward trend. We are helping all 38 members of the IEA Family, and all other countries around the world, in their energy transitions with targeted policy advice aimed at accelerating investment in a global portfolio of renewable energy technologies, as well as energy efficiency, carbon capture, utilisation and storage, and all other clean-energy technologies,” said Birol.
