The article discusses how using too much fossil fuels leads to climate change, with the energy sector being a major culprit. When we burn coal, oil, or natural gas to make electricity, it releases harmful greenhouse gases. Nuclear power generates electricity in a cleaner way, which some believe can help in reducing pollution and fighting climate change. The research points out that nuclear energy enhances energy security, ensuring a stable electricity supply similar to fossil fuels, and can work at a large scale effectively.
