    Wind farms usually function as one component of a larger energy generation and distribution system. As engineers seek to design power grids that draw larger percentages of the total power available from renewable sources, they must consider not only ?uctuations in the availability of individual renewable resources such as solar energy, wind, and water power, but also whether the same weather conditions might a?ect the availability of several di?erent resources. An e?cient system will include renewable components that complement each...
