Nuclear's Decline: A Reality Check Amid Rising Renewable Power

The UK government's push for nuclear power faces growing challenges as renewable energy continues to gain momentum. Despite reassurances from Keir Starmer and the International Energy Agency (IEA), the nuclear industry struggles with high costs, time overruns, and significant delays. Meanwhile, renewable energy capacity has grown to a record 582 GW, accounting for 91% of all new power generation. The evidence suggests that nuclear's stagnation is not due to regulation but rather its fundamental weaknesses.

Key Takeaways:

• Nuclear power adds as much net global capacity as renewables every two days, highlighting the industry's struggles with costs and delays.
• The UK Prime Minister blames regulation for nuclear's woes, but evidence suggests that costs and time overruns are the primary issues.
• The Rolls-Royce SMR design is larger than initially claimed, requiring significant resources and infrastructure.
• SMRs are expected to produce more chemically and physically reactive waste than large reactors, contradicting the industry's marketing claims.
• The renewable energy sector continues to innovate and expand, with costs falling and efficiency improving.
• The Intergovernmental Panel on Climate Change (IPCC) estimates that renewables are 10 times more efficient than new nuclear for CO2 mitigation.
• Build times for new nuclear reactors are significantly longer than for solar and wind installations, making renewables a more practical choice.
• The UK government's £47 billion Sizewell C project costs may rise significantly, underscoring the economic risks of nuclear power.
