The wind source of energy is one of the oldest that is known. This type of energy, as well as the photovoltaic solar energy is classified as renewable ones. The wind energy can be used by human beings in activities that require great mechanical efforts such as: navigation, agricultural products processing, water pumping through wind indicator, as well as water pumping through photovoltaic system utilization. The interest on clean energies got technologically reduced due to the rise of new technologies, as hydraulic, thermal and nuclear ones which present interesting advantages, such as more ease of control, more access and less cost in the processing. However, they can cause environmental damages and they show incapable of attending the growing energetic demand. In this book, we aim at developing two-systems irrigation of low pressure, in fruit crop. A winding system consists of a multiple blades, Savonius wind indicator and respective pumps, and another photovoltaic system consisting of pumps and a photovoltaic panel. In the photovoltaic system, the pumped volume was about 5000 m3/h, and in the wind system the pumped volume was 6 m3/h approx. The wind sets showed low efficiency.
