I'm backing you up on this one. Wind is a source of energy. The law of conservation of energy says that energy cannot be created or destroyed, thus implying that there is a finite amount of energy. The same thing that he is saying about wind applies to solar energy as well. The more energy from the sun that we turn into electricity, the less energy is being transformed into heat. It would take a lot of solar panels to make a difference, but we can't just place as many as we want and expect no change.
