A new study on Denmark’s future energy system reveals that a combination of offshore wind and solar energy would cost about €46 ($54.20) per MWh, making renewables 53% cheaper than nuclear power in the same system. This study, published in a peer-reviewed journal, takes into account not only the generation costs but also additional factors like grid balancing, energy storage, and sector coupling. Researchers argue that the total system costs for renewables, when integrated into Denmark's future climate-neutral energy framework, are significantly lower than those of nuclear energy. The study provides a comprehensive comparison of the energy sources' costs, showing that, once these additional factors are considered, renewables are a more economical choice. The findings challenge the viability of nuclear energy as a sustainable solution for climate goals, suggesting that investing in renewable technologies may offer a more cost-effective route to decarbonization.
