Two pros and two cons of wind energy
Wind energy is free, renewable and pollution free. Windmills are set up faster than dams and power plants. However, wind speed is variable, turbines break down and birds can be killed flying into them. The electricity is expensive to generate.

Two pros and two cons of coal energy
It is cheap and there are large quantities of available coal. However, mining is dangerous and burning coal can create air and water pollution. As coal is non-renewable, it will eventually be used up, or be too expensive to mine.
