We’ve known for a long time that nuclear energy is a false solution to climate change. Not only are the health and environmental impacts of nuclear power intolerable, but it also gobbles up investments we should be making in clean and safe renewable energy. Now, a new study by researchers at the University of Sussex in the UK brings us the latest and most robust evidence of these facts. The study, published last week in Nature Energy, considers three hypotheses: Firstly, that emissions decline the more a country adopts nuclear power; secondly, that emissions decline the more a country adopts renewables; and thirdly, that nuclear and renewables are ‘mutually exclusive’ options that tend to crowd each other out at an energy system level. The hypotheses were tested against 25 years’ worth of electricity-production and emissions data from 123 countries. The result? Investment in nuclear is mostly negatively correlated with decreases in carbon emissions, while investment in renewables was positively correlated with such decreases across the board. In other words, countries that invested in nuclear didn’t see emission reductions but countries that invested in renewables did.
