Modern energy sectorEnergy storage is the process of storing energy that has been produced at one moment and using it at another moment. Energy storage is important for increasing the efficiency and flexibility of the energy system because it reduces dependence on instantaneous energy production and consumption. Energy storage can take place in different ways, for example by using batteries, pumped storage plants, flywheels or hot storage. Energy storage also has a positive impact on the environment by encouraging the use of renewable energy sources and reducing greenhouse gas emissions.
