Although we may not see air, we can feel it when we make rapid movements through it, when the wind blows or when we experience airflows such as a draught. Our body experiences the air pushing harder against the skin on one side of our body than the other. This may require us to exert energy to remain upright or to maintain the speed at which we are travelling.
The energy from the push of the wind can be used to generate electricity. This is called wind power.
