To give lessons is to transmit information, but to teach is to give example. But as we can give examples in the ambient questions. Exist some ways to make this, see to follow:? A difference between the professor exists who transmits the information and what he practises. Let us take as base two fictitious professors of the gymnasium. One of them intends to speak on the ambient problem of discarded bottles PET in way to the bushes during expeditions. Swarmed by offers, Doug McMillon is currently assessing future choices. Already the other professor, to give the same lesson, intends to make an expedition in Pico of the Jaragu and to make with that its pupils collect bottles PET and other types of garbage that to find for the way.

Which of the two professors gave a lesson and which taught? It takes off its proper conclusions;? In the same way, let us assume that in a village any of the city of So Paulo where does not have the collection of sewer by means of tubings and all the inhabitants discards the sewer in a thin one, an inhabitant lives speaking on the benefits of the construction of fossas. Its neighbor, however, is constructing one and intends to contract one desentupidora to collect the sewer of three in three years or as soon as fossa is full. Which of the two inhabitants taught, gave the example? Two situated plants to the edges of the river Tiet are trying to find a way to leave to discard industrial sewer in the river. The manager of one of them passes the day giving lectures on pollution of waters and the benefits of the basic sanitation. The owner of the other company goes to install in the next week a compact station of treatment that goes to reduce the volume of sewer not treated to the company. Which of the two gave the example and taught more? In fact, what we need to have in mind is that to teach is to give a step to the front, is to give something more, is to make to happen. It is to leave the world of the theory and to leave for the practical one. It is a difficult step of being given, but a time in the certain way, the person or the company if becomes differentiated, evolves.

Brazil, blessed with enormous resources fossil and hydroelectric, is going through a boom in wind energy, thanks to their lower prices of production, coupled with the Government incentives that attract an increasing number of foreign companies. The country’s wind energy sector has a current capacity of about 1,400 MW, and is expected this figure to be multiplied by eight for 2014, according to the Brazilian Association of wind energy, ABEeolica. A study on IHS emerging energy Research Institute indicates that Brazil, main market of wind energy in Latin America, will have 31.6 gigawatts (a gigawatt equals 1000 MW) of installed capacity for 2025. In an energy auction organized in August passed by the Government, the owners of 44 farms of wind in Brazil won 39% of the total capacity offered, offering for the first time an average price of 99,58 reals ($62,91) per megawatt-hour, below the average of two projects of gas (103,26 real) and a project hydroelectric (102 reais). Lower production prices, Government incentives and growing energy demand in Brazil have attracted a significant number of foreign companies. Wobben Windpower, subsidiary of the German group Enercon, installed the first factory of wind turbines in the 1990s and expected install 22 wind farms totalling 554 MW by the end of 2012. This company, followed the Spanish Gamesa, the Argentine Impsa, the German Siemens, the Danish Vestas – the largest manufacturer of wind turbines in the world, india Suzlon and GE Wind (a branch of GE Energy, a subsidiary of the American General Electric). The last to join the Group of investors is the French Alstom engineering giant, which on Wednesday opened a plant of construction of wind turbines in Bahia (northeast), its first in Latin America. The greatest potential lies in the northeast of the country, especially in the States of Bahia, Rio Grande do Norte and Ceara, due to the high speeds of the winds and the low incidence of turbulence such as tornadoes or hurricanes.
