Global Renewable Energy Growth Surges as Fossil Fuel Costs Rise
In a landmark report released today, the International Renewable Energy Agency (IRENA) revealed that renewable energy capacity additions reached record levels in 2023, with solar and wind power leading the charge. The agency’s annual World Energy Transitions Outlook highlights that renewables now account for over 38% of the world’s electricity generation, up from just 25% in 2018.
Solar photovoltaic (PV) installations dominated the growth, expanding by 223 gigawatts (GW) last year alone, according to IRENA Director-General Francesco La Camera. “This is not just a trend—it’s a transformation,” he said in a statement. “The cost of solar and wind energy has dropped dramatically, making them the most competitive energy sources in most regions.”

The report also underscores that 14 countries now derive over half of their electricity from renewables, with Denmark, Uruguay, and Norway leading the pack. In contrast, fossil fuel-based generation has stagnated, with coal plants retiring at an unprecedented rate. The agency projects that by 2030, renewables could supply 60% of global electricity demand if current policies are maintained.
Economic factors are driving the shift: the average cost of utility-scale solar PV fell by 89% between 2010 and 2023, while onshore wind costs dropped by 56% over the same period. “This cost advantage is irreversible,” La Camera noted, adding that governments must now focus on grid integration and energy storage to fully unlock renewables’ potential.

Critics argue that millions of jobs in the fossil fuel sector could be displaced without a just transition plan. However, IRENA estimates that the renewable energy sector already employs over 13 million people worldwide, with solar and wind accounting for the majority of these positions.
The findings come as global energy prices remain volatile, with fossil fuel costs surging due to geopolitical tensions. The report warns that without accelerated renewable deployment, the world risks missing its 1.5°C climate target by 2030.
