IEA: Anti-Nuclear Activism Threatens Climate Targets

Report warns 2/3 of capacity could be lost by 2040 as developed nations phase out old nuclear plants

A steep decline in nuclear energy capacity will threaten climate goals and power supply security unless advanced economies find a way to extend the lifespan of their reactors, the International Energy Agency said.

Nuclear is currently the world’s second-largest source of low-carbon electricity, behind hydropower, and accounts for 10 per cent of global electricity generation. But nuclear fleets in the United States and Europe are on average more than 35 years old and many of the world’s 452 reactors are set to close as cheap gas and tighter safety requirements make it uneconomical to operate them.

“Without policy changes, advanced economies could lose 25 per cent of their nuclear capacity by 2025 and as much as two-thirds of it by 2040,” the IEA writes in its first major report about nuclear energy in two decades.

Over the past 20 years, wind and solar capacity has increased by 580 gigawatt (GW) in advanced economies. According to the U.S. Office of Energy Efficiency and Renewable Energy, one GW of power is equal to 100 million LED light bulbs or 431 utility-scale wind turbines. Despite that, however, IEA estimates that the 36 per cent share of clean energy sources in global power supply in 2018 was the same as two decades ago because of the decline in nuclear. […]

EA director Fatih Birol said … the low-carbon nature of nuclear and its role in energy security are currently not sufficiently valued for existing nuclear plants to operate profitably and that new nuclear projects have been plagued by cost overruns.

“Without action to provide more support for nuclear power, global efforts to transition to a cleaner energy system will become drastically harder,” Birol said.
