There are many types of energy in the world that make up electricity, such as
chemical, thermal, mechanical, nuclear and many others. The speciality of all types of
energy are that they must have a source from which resources are fixed for the formation of an electric flow of energy. And that's a big problem. They depend on, so to speak, the source of certain energy - coal, water, nuclear fuel and so on. There is also a problem at the time that those resources are becoming scarce and people are starting to turn to alternative energy sources.
