With the growing population, energy demands also increase. Moreover, one of the objectives of SDG 7 – Affordable and Clean Energy for all is to provide access to electricity to 13% of the population which currently has none. This additional energy needs to be supplied in a more optimized way, with the emphasis on renewables. In the case of solar or wind power, this is not always generated, so it needs to be stored. And how about locations which have little or no access to renewables due to their geography? The solution to this is the smart grid.
