Give two environmental advantages of using a gas-fired power station to generate electricity compared with using a coal-fired power station.

Lower Carbon Emissions: Gas-fired power stations generally produce significantly lower carbon dioxide (CO2) emissions compared to coal-fired power stations. When natural gas is burned, it emits about 50% less CO2 per unit of electricity produced than coal. This reduced carbon footprint is crucial for mitigating climate change and meeting international emission reduction targets.

Reduced Air Pollutants: Gas-fired power generation results in lower emissions of harmful air pollutants such as sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter (PM). Coal combustion releases large amounts of these pollutants, which can contribute to smog formation, respiratory problems, and acid rain. Gas-fired plants, particularly those using combined-cycle technology, can help improve air quality and reduce public health risks associated with air pollution.
