Renewable energy has been demanding in recent years and work on it has increased, but it does not have the potential to meet the required energy level. Energy can only meet high demand when it is used more efficiently and when correct conversions are made. The correct and economical use of energy can only be achieved by storing energy. There are many problems such as the situations where the resources are present and insufficient, the unbalance of the production consumption and the supply demand balance are prevented by storing energy. There are many ways of storing energy. When we examine these under 4 headings; electrical energy storage, mechanical energy storage, thermal energy storage and chemical energy storage.
