Solutions for using renewable energy sources to produce electricity and to provide water for domestic supply and irrigation

Environmental pollution, greenhouse effect, intensification due the wide-ranging of organic fuel, as well as care of energy supply to the future generations caused the accelerated development of technologies oriented to the use of renewable energy sources. Some of these technologies are shown in the paper where some examples of the methods to produce electricity and to provide water for irrigations in the places where there is no access to a large electricity grid like small isolated communities, remote consumers, rural villages, inquiring centers, light houses, inaccessible farms, shelters, telecommunication stations are presented. In order to produce electricity a solution of a wind turbine with vertical axis helical rotor shape with good energetic performances is presented. Also, in the paper some considerations regarding the use of renewable energy sources are presented in order to pump water that can be used in different ways including supply water for domestic needs or for irrigation in small-scale area of lands. In this direction two solutions of using renewable energy sources with a wind turbine to pump water for houses and to pump water that is used to irrigate land of small farmers are shown.
