What Have Cars And Cold Air Got To Do With Energy?

Today we use many sources of energy. Some produce too little power, some too much at different times. All power supplies are intermittent, to a greater or lesser extent. However, with the rise of renewable energy in the grid the challenge of storing the surplus energy and making it available when it's needed the most becomes greater.

We have heard it so many times: the sun doesn't always shine and the wind doesn't always blow. Does that really mean that our electricity system needs to stay dependent on fossil fuels? Are alternative systems based on smart solutions that allow for more dynamic energy management possible?

In its interactive storytelling piece, BBC examines new approaches to smart power and presents some of the recent storage solutions in Europe. An easy Sunday afternoon read.
