Is petroleum clean

Petroleum is not considered clean due to its extraction, refining, and combustion processes, which release greenhouse gases and pollutants into the environment. While it is a significant energy source, its use contributes to air and water pollution and is linked to climate change. Efforts to mitigate its environmental impact include cleaner extraction technologies and carbon capture, but these do not eliminate its inherent environmental risks. Transitioning to renewable energy sources is seen as a more sustainable solution.
