table that can store electricity

Why is electrical energy so difficult to store?

2. A general answer which is not of any particular use is that electrical energy, and the forms in which we store it, are typically very low entropy systems. The lower the entropy the more they "want" to dissipate and the harder it is to stop that tendency to turn into (ultimately) heat.

How can we store electricity?

Place a ball on a table – you give the energy to raise the ball off the floor. Rolling it over the edge releases that energy and the ball falls. Stretch an elastic band – you provide the energy to stretch the material out and letting go will ping it back to shape and release that energy. In each case we can give energy to the system and ...
