Due to its cleaner combustion, natural gas is the most environmentally safe fossil fuel. Natural gas doesn't have as many toxic combustion byproducts as other fossil fuels.
- Natural gas is adaptable. Starting and stopping a gas-fired power plant is substantially faster than one that burns coal.
- Due to its flexibility, it complements renewable energy sources like solar and wind, which are only usable when the sun is out and the wind is blowing.
- When burned to produce power, natural gas is the cleanest-burning hydrocarbon, releasing about half as much carbon dioxide (CO2) and only one-tenth as much air pollutants as coal.
- By switching to natural gas from coal, there is a significant opportunity to cut CO2 emissions and air pollution in the near future.
- Because Natural gas is now so widely accessible through LNG, it can assist nations in coping with short-term supply interruptions.
