... cars and trucks. Friediger 7 Conservation of energy is the best way. Just turning down the thermostats means using less fuel. Using public transportation would save a great deal of energy. Less electricity used means less production at power plants. That means less burning of coal. Another way is to clean coal before it is burned through a physical, chemical or biological mean. Also ... scrubbers capture the sulfur before it reaches the air. The sulfur is sprayed with lime. Another way is to use low sulfur fuels, though this would raise the price of electricity.
