This work consists of the development of method for specification of systems for residential rural energização with use of panels fotovoltaicos and of hybrid units (aerogeradores and panels fotovoltaicos), complemented by the wood use for production of heat. A software was developed for dimensionamento of the system of electric supply through data of solar radiation and of monthly medium speeds of wind. The method was tested in the northeast area of RS. The main electric charge is composed by compact lamps of 15 W, refrigerator of 290 L and television color 14." The users are guided to use the energy perfazendo rationally a medium monthly consumption of 40 kWh. The wood consumption is of difficult quantification and control, because his/her use is traditional in the area, besides in the urban areas. In the rural area, most of the wood is obtained of forest residues in the property where is consumed. Already in the cities, where the firewood is acquired of third, the estimates appear for a close medium consumption of 1,5 stereos, or approximately 3.300 kWh/mês. The systems of electric power generation, specified after the due fittingses in the method, they present the following configurations: the) five panels PV of 75 W; and, b) an wind generator of 400 W and two panels PV of 75 W. Both systems, they are composed by the following ones outlying: I support of six batteries, 12 V, 115 Ah; load controller; and, investor CC/CA 1000W.
