Coal is cheap, but pollutes the air

Oil is a tiny bit more expencive than coal, and gives just a mini tiny bit of smaller pollutions

Gas is cleaner than both coal and oil, but costs nearer twice as much per MW than coal and oil

Nuclear is able to provide a big city with electricity, but if it gets blown up, you wont be able to build on the ground that the meltdown hited. The UFO:s seems to love blasting theese.

Wind has no pollution on the air, but you will need millions (not quit that much but you get the point) of them to provide a big city with electricity.

Solar is non-polluting but needs some of them to give  good flow of electricity. If its cloudy, there wont be any power

Waste is excellent when you have no power and tons of garbage, but is excpensive to build and doesnt provide much electrycisy

Microwawe is very clean since the energy is produced in space and then beamed down here. But sometimes the beam hits buildings next to the plant and destroy them, and thats not good.

Fusion is very clean and not dangerous as Nuclear or the Microwawe but is very excpensive.
