2 points

decrease coal consumption

1.coal

2. coal  

3.wind

4. increased greenhouse gases

1. decreased coal consumption:  The coal is a fossil fuel obtained from mining of the deep earth's crust. The coal is the main source of carbon, it is used to generate thermal energy. The heat liberate includes gases like carbon monoxide and carbon dioxide which are chief polluting gases of the atmosphere.

2. coal: Burning of coal will produce gases like carbon monoxide and carbon dioxide, these are greenhouse gases which can cause air pollution.

3. coal: Coal is the fossil fuel which will produce most of the carbon dioxide after combustion.

4. wind: Wind energy is harnessed by fast blowing wind which is used to move the wind turbine or wind mill to obtain it's energy in generation of electricity.

5. increased greenhouse gases: The use of fossil fuels is related with the release of energy in the atmosphere in the form of carbon dioxide, carbon monoxide, sulphur dioxide and nitrous oxide.
