Which type of electric generation does not contribute to green power?

Coal generation is the type of electric generation that does not contribute to green power. This is because coal-fired power plants emit high levels of carbon dioxide and other greenhouse gases, which significantly contribute to air pollution and climate change. Unlike renewable energy sources such as solar, wind, and hydropower, coal is a fossil fuel that is non-renewable and involves extracting resources that can harm the environment.

In contrast, solar energy harnesses sunlight to produce electricity without air pollutants, wind energy utilizes the natural movement of air to generate power cleanly, and hydropower generates energy through the movement of water, both of which have much lower direct emissions. Therefore, coal generation stands out as not aligning with the principles of green power, which aim to reduce environmental impact and promote sustainability.
