Energy is the engine of modern life. Whether the form of electricity or natural gas. In Germany, the consumption of electrical energy at a very high level. The breakdown of electricity consumption in Germany is as follows: 43 percent of the industry, 27 percent of households, 27 percent of trade, commerce and services and 3 percent for transport. The generation of electricity takes place for the majority of consumers in Germany in large power stations with several hundred megawatts of power. For comparison, a German 4-person household needs a capacity of up to 5 kW, for example, in a house. In the coal-fired power plants that are fueled with lignite or coal, and nuclear power plants are most closely involved in energy production. The production of energy from renewable sources is still very low so far, but will be expanded in the coming years. In fact, coal plants are not very environmentally friendly, at least so far put into operation, although with special filtering procedure, the emission ofPollutants could be reduced. Nuclear power plants that are very environmentally friendly power generation during the process, but rather the elimination or storage of spent nuclear fuel, like the dangerous radioactive radiation is a major problem. So-called underground disposal facility shall ensure that decreases the radiation of nuclear waste for decades. The actual production process in the different types of power plants is basically always the same. With energy such as coal or nuclear fuel, heat is generated. This heat converts water into steam in steam generators. The hot and under high-pressure steam flows through a pipe to the turbines and drives them. The turbines are connected to the generators, which then generates electricity. Incidentally generators work like a bicycle dynamo by rotary motion is generated in the generators of large metal coils of electrical energy. However, it also invested heavily in the worldwide production of natural gas. There are so-calledGas-turbine power plants. They are using natural gas as fuel power plants of medium size, which is operated for example by municipal utilities for the self-sufficient supply of large cities with electricity and heat.
