O presente trabalho possui o intuito de analisar o panorama de energia eólica em âmbito mundial, dando um enfoque maior para seu cenário no Brasil. Primeiramente, estudando a história da energia eólica, seu advento, para fins de solução ao viés ambiental e à necessidade de diversificação da matriz energética mundial, com a finalidade de assumir os compromissos firmados no Protocolo de Kyoto, e, no caso do Brasil, da menor dependência do abastecimento externo

This paper is about a case study of using solar energy and wind energy in a farm. For this purpose were collected from the property, such as water consumption and amount of residents. So, we estimate how many conventional panels or PET bottle panels and boiler needed to supply the farm with warm water. It also calculates the amount of photovoltaic panels and the main accessories for converting solar energy into electrical energy. For the pumping of water using photovoltaic panels is dismissed and dimensioned to be a watermill

The energy crisis has affected many countries. With the growing warning with the emission in the atmosphere and the lack of resources, the seek for sustainable sources for energy genaration have become even bigger. Some Countries, as Germany, started first in this journey, creating an incentive program to self-generation with renewable sources (wind, photovoltaics, biomass, etc.), giving priority for smaller plants. In Germany the program called EEG started in 2004. In Brazil, since the beggining of 2012, the self-generators did not know how they could be beneficted for self-generation, and self-generation didn't become commun in the country. However, with NR 482, of April 17th, 2012, the parameters were defined, and the self-generator could have a guideline. Therewith, studyies can be redirected for a better knowlegde of the conditions the self-generator will be sujected, in addition to Germany's case as reference to compare with Brazil's case. In this paper these studies are made, focused in wind power (wind turbines) and photovoltaic panels

Brazil economic growth has to predict the need for implementation of new energy sources to ensure the continuity of the economic growth and improvement of life of the brazilian population. Until this moment, this assistance included the construction of large hydroelectric plants, mainly in the amazon region, where the environmental impact is difficult or, as in the case of the Belo Monte made this impossible so far, the implementation of these projects. In this work is conducted a study that demonstrates an example of application of wind energy, through an assessment of wind resources in the brazilian Northeast for the implementation of a wind farm

The renewable energy sources presents an important role on the world's current context, its growing is essentially connected to the environmental issues and the energetic security, guided by the search for alternatives of energy. Among the alternative energy sources, the wind energy shows great importance in the brazilian territory, it has a great potential still unexplored and constant growth in the national electric matrix. The specific factor of generation, the conjuncture and the incentive politics influence on the expansion of wind energy in Brazil. Thus, the brazilian wind sector shows features which can be evaluated enable its developing. Keeping that in mind, the present work aims identify which are the advantages and the difficulties for the expansion of this energy source in the brazilian electric matrix. For that, the work studies the different parameters: features of electric generation of the different energy sources, incentive politics, generation costs, CO2 emission, evolution of wind energy in Brazil, the brazilian wind potential, and the regime of complementarily hydro-wind
