We must have renewable energy. But it often comes at times when it is not useful, and may not be available when it is needed. The only way to rely on it is to store it.

EnergyMag.net focuses on renewable energy storage: why we need it, how to store it and what it costs, We discuss technologies and business models, we follow companies, we interview CEOs and CTOs, we keep track of available sources of capital.

We maintain an extensive renewable energy storage company directory (200+ companies), and a thorough directory of funding sources for renewable energy storage (the 170+ companies that have funded grid energy storage since 2009).

So, if you are interested in energy storage, even a little bit, come back often, subscribe to our blog, and follow us on twitter!
