Windmills are used to convert wind energy into a more useful form. In most cases, there are three
steps in the process. The energy is in a different form at each step. Which of the following flowcharts
shows the most likely order of the energy changes?

edit: Sorry lovelies! Here are the flow charts!
wind energy ---> mechanical energy ---> solar energy
wind energy ---> thermal energy ---> mechanical energy
wind energy ---> solar energy ---> electrical energy
wind energy ---> mechanical energy ---> electrical energy
