A list of least carbon efficient power stations can be referred to by several synonyms, such as power plants with the highest carbon intensity, carbon-emitting energy facilities, or the dirtiest energy generators. These synonyms emphasize the negative environmental impact of power stations that produce high levels of carbon dioxide and other pollutants. Additionally, other terms like nonrenewable energy producers, fossil fuel-dependent plants, or high-emissions power sources may also be used to describe the same facilities. Identifying and minimizing the presence of high-carbon power stations is essential to mitigating climate change and preserving the environment for future generations.
