The constituent of the exhaust fumes from electricity generating sets which causes serious pollution is Carbon Dioxide (CO2). CO2 is a colorless and odorless gas that is released when fossil fuels like coal, oil, and natural gas are burned to generate electricity. While it is a naturally occurring gas, the burning of fossil fuels has caused a significant increase in the amount of CO2 in the atmosphere, leading to a phenomenon known as global warming and climate change. This increase in CO2 levels has caused the Earth's average temperature to rise, leading to changes in weather patterns, melting of polar ice caps, and rising sea levels. These changes are having a profound impact on the planet and its inhabitants, making it crucial for us to reduce our carbon footprint and transition to cleaner, renewable sources of energy.
