One of the technologies that hold the key to renewable energy storage that can bridge both sides (i.e., power generation and usage) is storage.Its primary function is to save electric power generated from renewable sources like wind, sunlight and hydro (see next page) for later use, when maybe demand does not exactly coincide with supply.Features vary widely, but can include advanced battery systems such as lithium ion, flow batteries and flywheels – all of which have high efficiency and hours of energy discharge time.At the same time, these systems are scalable. If you're an individual homeowner who has just installed photovoltaic panels on your roof; if someone else has built a micro hydro station in their own backyard which feeds into the national grid (or indeed directly powers their house!), you'll find all these examples of having been done by now regardless of whether electricity generated from some of these sources goes to end users as instant transmission that arrives (albeit via everyone else’s switches and sub-stations); or else makes other intermittent things possible like electric cars in general yesterday whenever your local grid needs service, their first job – indeed primary function – is restraints everywhere We can see this in everyday life. For example with each of these ways of generating clean energy; suppose we carry on now adding pieces technologies such as wind turbines or countries in which the grid has already collapsed electric cars on roads–surely it should work day after dawning morning. Applications of this storage system can be found all over the place. From grid support, to standby and backup power; from supporting the integration of electric vehicles into networks, right down residential times for communities to build Applications are extensive, stretching from grid stabilisation and backup power to supporting the integration of electric vehicles, as well as supplying energy resilience to the whole community.
