            Wind power stations use the wind force to produce electricity. The wind moves the propellers of the turbines placed in high places and thus electricity is generated.

            The solar power stations use the light of the Sun to produce electricity. This is received by solar panels that the light transforms into electricity.

            The solar and wind power stations do not contaminate the air but they produce little electricity.
