Wind Energy Systems

Wind-electric systems fit into three categories: (1) grid-connected, (2) grid-connected with battery backup, and (3) off-grid. In this chapter, we’ll examine each system and discuss the pros and cons of each. We’ll also examine hybrid systems, consisting of a wind turbine plus another form of renewable energy. This information will help you decide which system suits your needs and lifestyle. To begin, let’s take a look at two of the main components of wind systems, wind turbines and towers. Subsequent chapters contain more detailed discussions of these and other components.
