The turbine blades turned by the wind and are connected to an electrical generator. Work is the exertion of a force over a distance. Energy is the capacity to perform work. Power is the rate of work performed per unit time. Students may find a basic physics text helpful in obtaining these definitions. Technically, it is the vector dot-product of force and displacement, meaning that work equals force times distance only if the force and distance vectors are precisely parallel to each other. In other words, if I carry a 10 kg mass lifting up against the tug of gravity while walking parallel to the ground not going up or down , the force and displacement vectors are perpendicular to each other, and the work I do in carrying the mass is zero.
