Solar output is expected to lead a surge in renewable power supply in the next decade, the International Energy Agency (IAE) said, with renewables seen accounting for 80% of growth in global electricity generation under current conditions.

In its annual World Energy Outlook launched this week, the IEA said in its central scenario – which reflects policy intentions and targets already announced – renewables are expected to overtake coal as the primary means of producing electricity by 2025.

The combined share of solar photovoltaic (PV) and wind in global generation will rise to almost 30% in 2030 from 8% in 2019, it said, with solar PV capacity growing by an average 12% a year.

I see solar becoming the new king of the world’s electricity markets,” IEA Executive Director Fatih Birol said. “Based on today’s policy settings, it is on track to set new records for deployment every year after 2022.”

Power generation from renewables is the only major source of energy that continued to grow in 2020, the Paris-based agency added.

A more ambitious scenario, including for instance the adoption of net-zero emissions targets by 2050, would see PV electricity generation perform more strongly still, the report said.

The IEA said gaps remain in many cases between long-term ambitions and specific near-term plans to curb emissions.

Integrating new wind and solar power will depend on adequate investment in all parts of the system, including distribution networks.
