How does teaching the public about energy conservation decrease air pollution? a. increases the supply of electricity b. reduces the demand for electricity c. reduces the cost of electricity d. increases the consumption of electricity

It reduces the demand of electricity because if people want to decrease the amount of air pollution they would stop using things that would cause pollution for example, people stopping to use gasoline powered cars and use electric cars more, therefore the demand for electricity will go low since lesser people will be using it.
