Power generation and energy efficiency
Energy efficiency became a topic of discussion shortly after the oil crisis in the 1970s, when it was realized that fossil reserves would not be cheap and abundant forever. In addition, it was also at this time that there was a greater awareness of the damage that the use of this type of fuel generated for the environment. As a result, it was necessary to think of alternatives to maintain energy generation, using other sources and improving the efficiency of those already used.
