Why Nuclear Power Is a Bad Investment for America

The United States cannot build additional nuclear power facilities because they are too expensive, too slow to build, and too risky compared to other forms of energy. While nuclear is a low-carbon source of electricity, its high upfront costs, lengthy development timelines, and ongoing safety concerns make it unviable. The Vogtle nuclear plant in Georgia, for example, was initially estimated to cost $14 billion, yet the cost has exceeded $36.8 billion following successive delays. In addition, the U.S. still has 90,000 metric tons of nuclear waste at interim facilities, with no permanent disposal solution. The lack of a central storage site for high-level radioactive waste increases environmental and security risks in the long run. Instead of investing billions in nuclear expansion, the U.S. must prioritize faster, cheaper, and safer renewable energy sources with shorter deployment timelines.

Nuclear proponents argue that new plants can provide stable, carbon-free electricity to meet growing demands. They claim nuclear energy is essential for energy security and climate goals while offering a reliable complement to intermittent renewable sources. Yet nuclear is the most expensive form of electricity generation, with new reactors three to five times more expensive than wind or solar. New reactors take from 10 to 19 years to build on average, so are a poor response to urgent climate needs. Wind and solar farms, in contrast, can be built in under two years and provide a scalable energy solution. Meanwhile, nuclear plants remain vulnerable to disasters like Chernobyl and Fukushima, where radioactive leakage caused long-term environmental and economic damage. Even low-grade nuclear accidents can result in billions of dollars in cleanup costs along with public health risks, imposing a burden on taxpayers.

The cost of nuclear energy is prohibitive. The only new U.S. reactor built in decades, Plant Vogtle, was $17 billion over budget and took 14 years to complete, demonstrating the economic barriers to nuclear expansion. Even so-called small modular reactors (SMRs), touted as the future of nuclear, have already proven themselves too costly, with the first U.S. SMR project canceled after costs inflated 53% over estimates. In the meantime, the price of solar electricity has dropped 89% since 2009, and wind power is now one of the least expensive forms of energy. Renewables take months, not decades, to deploy, providing a faster path to decarbonization without nuclear's financial risks. Nuclear facilities also need huge volumes of water for cooling, exposing them to climate-related disruptions like droughts and heat waves. As weather events intensify, reliance on nuclear energy can lead to operational disruptions and power shortages during times of highest demand. The energy sector must include climate resilience, and nuclear power just doesn't meet that test.

Rather than investing in outdated, costly, and dangerous nuclear plants, the U.S. must continue to increase investment in renewables, battery storage, and grid modernization. Federal subsidies must shift away from nuclear projects and towards wind, solar, and energy efficiency to achieve an affordable, sustainable future. Other countries, like Germany, have dropped nuclear while already accelerating renewables, proving that clean energy is possible without nuclear dependence. Investment in smart grid technology and energy storage facilities can render renewables more dependable and a more viable and affordable alternative to nuclear power. If the U.S. is serious about energy independence and environmental progress, policymakers must prioritize renewables over nuclear investments. The future lies in fast, scalable, and cheap clean energy solutions—not in expensive, risky nuclear projects. The U.S. has a critical opportunity to lead the world in transitioning to clean energy, but that will only happen by prioritizing renewables.
