Identify a way to reduce the pollution caused due to burning of fossil fuels

The correct answer is Option 2. 

Key Points

•  Increasing the efficiency of the combustion process can indeed help reduce the pollution caused by burning fossil fuels. Here are a few ways in which efficiency improvements can be achieved:
  • Advanced Combustion Technologies: Utilizing advanced combustion technologies such as pre-combustion chambers, staged combustion, and optimized fuel-air mixing can enhance combustion efficiency. These methods ensure that fuel is burned more completely, reducing the production of pollutants.
  • Fuel Quality: Using higher-quality fuels with lower impurities and better combustion properties can improve combustion efficiency and reduce emissions. This includes using cleaner-burning fuels such as low-sulfur diesel or natural gas instead of coal or heavy oils.
  • Cogeneration and Combined Heat and Power (CHP) Systems: Cogeneration or CHP systems produce both electricity and useful heat from the same energy source. By capturing waste heat from power generation and utilizing it for heating or other industrial processes, these systems improve overall energy efficiency, reducing the need for separate fuel burning and associated emissions.
  • Energy Efficiency Measures: Implementing energy efficiency measures in industrial processes, buildings, and transportation can reduce the overall energy demand. By using energy more efficiently, the need for burning fossil fuels can be minimized, thereby lowering pollution levels.
  • Carbon Capture and Storage (CCS): CCS technologies capture carbon dioxide (CO2) emissions from power plants and industrial facilities and store them underground or use them for other purposes. While not directly increasing combustion efficiency, CCS can help reduce greenhouse gas emissions and mitigate the environmental impact of burning fossil fuels.
• It is important to note that while increasing combustion efficiency can reduce pollution per unit of energy generated, it does not eliminate the fundamental environmental concerns associated with the combustion of fossil fuels.
• Transitioning to cleaner and renewable energy sources remains crucial for achieving significant reductions in pollution and combating climate change.
