Natural gas is considered cleaner than coal due to its lower emissions.

Natural gas is considered a cleaner alternative to coal because it produces fewer emissions when burned for energy. Compared to coal, natural gas emits significantly lower amounts of carbon dioxide (CO2), sulfur dioxide (SO2), and particulate matter, which are harmful to both human health and the environment. This is one of the reasons natural gas has become the preferred fuel for electricity generation in the U.S. While still a fossil fuel, natural gas is seen as a bridge energy source in the transition to renewable energy due to its relatively lower environmental impact compared to coal and oil.
