Fact-Checked: Global Renewable Energy Growth Surges Amid Climate Crisis
Global renewable energy capacity expanded by 295 gigawatts (GW) in 2022, marking the largest annual increase on record, according to the latest report from the International Renewable Energy Agency (IRENA). This growth, driven primarily by solar and wind power, underscores an accelerating shift away from fossil fuels as nations scramble to meet climate targets.
China remained the world’s top installer of renewable energy last year, adding 135 GW of new capacity—more than any other country. The United States followed with 40 GW, while the European Union installed 45 GW, according to IRENA data.
“The numbers tell a clear story: renewables are no longer a niche solution but the backbone of the global energy transition,” said Francesco La Camera, Director-General of IRENA. “However, we must move faster to avoid catastrophic climate impacts.”
Solar power accounted for nearly 60 percent of all new renewable capacity in 2022, with wind energy contributing 38 percent. Hydropower and bioenergy made up the remainder. The report highlights that 83 percent of all new renewable capacity came from just 10 countries, reflecting uneven global progress.
Despite the progress, experts warn that current trajectories fall short of the 2,700 GW of additional renewable capacity needed by 2030 to align with the Paris Agreement's 1.5°C warming limit.
In Africa, renewable energy installations grew by 4.5 GW in 2022, with solar projects leading the way. The continent now hosts 10 percent of global renewable capacity, up from just 2 percent a decade ago. However, financing gaps and grid infrastructure challenges persist.
Corporate commitments to renewable energy also surged, with over 1,000 companies pledging to achieve net-zero emissions by 2050. Major tech firms like Apple, Google, and Microsoft have already transitioned to 100 percent renewable energy for their operations.
Critics argue that fossil fuel subsidies—totaling $7 trillion globally in 2021—continue to distort energy markets. “True progress requires phasing out these subsidies and redirecting funds toward renewables,” said a policy advisor at Greenpeace.
Looking ahead, IRENA projects that renewable energy could supply 60 percent of global electricity by 2030 under ambitious policy scenarios. The agency calls for accelerated deployment, improved grid integration, and stronger international cooperation to meet climate goals.
