Using a non renewable energy doesn't create any pollutions or CO2 emmisions.
For example, we can use wind to create energy!
Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetative cover. This wind flow, or motion energy, when "harvested by modern wind turbines, can be used to generate electricity.
The advantages of this wind-generating electricity is that wind energy is free, renewable resource, no matter how much is used today, there will still be the same supply in the future!
And unlike conventional power plants, wind plants emits no air pollutants or greenhouse gases.
Then why can't all people use renewable energy like wind energy?
Well, even though the cost of wind power has decreased dramatica
including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions!
And the biggest problem is that it emits CO2, when burning fossil fuel (Which is a non renewable resource!)
