How to reference this medium
Electrical energy should if possible be generated at precisely the time at which it is needed. This is because electrical energy is difficult and expensive to store. A distinction is made between direct and indirect stores for electrical energy. Electrical energy can only be stored directly in capacitors. With indirect storage, the electrical energy can be converted into a different form of energy which can then be stored.
Information and ideas:
Students should think about the economical use of the energy stores shown (for example: How much energy can be stored? Can the energy store be used without any problems? Where do losses occur?).
