Fact-Checked: Global Renewable Energy Growth Surges Amid Climate Goals
Global renewable energy capacity reached 3,060 gigawatts (GW) in 2022, marking a record expansion and underscoring the world’s accelerating shift away from fossil fuels, according to a new report by the International Renewable Energy Agency (IRENA).
The report highlights that solar and wind energy accounted for 91% of all new renewable capacity added last year, with solar alone contributing 60% of the total. This surge comes as governments and corporations ramp up efforts to meet the Paris Agreement’s target of limiting global warming to 1.5°C above pre-industrial levels.
“The data shows an unprecedented momentum in renewable energy deployment,” said IRENA Director-General Francesco La Camera. “This is critical as we work to decarbonize our energy systems and achieve climate neutrality by 2050.”
China led the expansion, adding 136 GW of renewable capacity in 2022—nearly half of the global total—followed by the European Union with 50 GW and the United States with 36 GW. The report also notes that developing nations, including India and Brazil, are increasingly investing in renewables to meet growing energy demand.
However, challenges remain. IRENA warns that current growth rates must double by 2030 to align with the 1.5°C target. “While progress is encouraging, the scale of the task is immense,” La Camera added. “We need sustained policy support, private sector investment, and international cooperation to bridge the gap.”
The report projects that renewables could supply 40% of global electricity by 2027, up from 30% in 2022, if trends continue. Offshore wind and green hydrogen are identified as key areas for future growth.
Critics argue that fossil fuel subsidies—estimated at $7 trillion globally in 2022—continue to distort energy markets. “Until these subsidies are phased out, the transition will remain uneven,” said climate economist Rachel Kyte.
For now, the data paints a picture of rapid change, with renewables now the cheapest energy source in most regions. The question remains: Can this momentum be maintained to avoid catastrophic climate impacts?
