We've discussed micro energy storage with home battery systems; now we go to the macro by looking at grids. There are many kinds of grids out there, so let's start with a basic introduction to some important grid-related terms and concepts.
Basic laws of physics tell us that that energy cannot be created or destroyed...but it can be saved as potential energy in the form of chemical, electrical, thermal, mechanical, nuclear, or many other energy forms. Energy storage, plain and simple, converts energy from forms that are difficult to store - like electricity - to more convenient or economical storable forms.
Today we highlight the undisputed world leader in renewable energy: Germany.
How is it that one of the world's largest economies can undertake such an ambitious goal of switching to clean energy? How can a country of over 80 million with some of the world's strongest industry already be producing 27% of its total electricity consumption in 2014 from clean energy, and be on its way to much higher future benchmarks?
