Social Factor
In order to consider a sustainable energy source, it is necessary that the source has the minimum base and the necessary social acceptance. Nuclear energy, for example, is widely used in countries such as France and Italy and is accepted as a source of clean and renewable energy. In Germany, however, the use of nuclear energy has by no means received the same social acceptance and has recently been abandoned. In order to have social acceptance, it is necessary to use energy resources according to the culture of that region or to pave the way for using other resources by raising awareness.
