Energy became one of the most necessary part of our modern life. The world requies more and more of it day by day. The most part of the natural primary energy sources can’t be used directly, they have to be transormed. The key things always changes, and nowdays electrical energy is it. The computers, the systems can crash in seconds without this it. By the growing deamnds cause the conquest of alternative ways of energy production. Th result of it is a better energy efficiency which means reducing emissions and greenhouse gases.
Efficiency is a complex notion, which means different thing to anybody. So first, we have to concider the basics. Efficient energy use, sometimes simply called energy efficiency, is the goal to reduce the amount of energy required to provide the same products and the same services.
In my master thesis I wouldd like to show different ways to increase the efficiency, the laws and permit in this theme. I wouldd like to show the ways to reduce the costs. At the end of my thesis I will present the renewable energy sources, which are the most important opportunities to prouve the efficiency and reduce the emissions.
