Extreme weather events in multiple regions caused power system challenges in 2022. Fuel prices surged after Russia's invasion of Ukraine, leading to a rise in coal-fired generation. Renewable power generation is set to increase more than all other sources combined, with renewables making up over one-third of the global generation mix by 2025. Nuclear output is expected to grow by 3.6% per year on average. Low-carbon generation sources are expected to meet more than 90% of additional electricity demand over the next three years.
