Economical energy storage has long been the Holy Grail of electricity. Since 1800, when Alessandro Volta invented the electric pile (a forerunner of the modern battery), hobbyists, scientists, and engineers have experimented with chemicals and materials to create economical storage at a smaller scale than a hydroelectric dam and with a more portable technology than, … More Two EV entries in the “how cool is this?” file
Yes, solar power systems are getting cheaper and battery storage is improving. The combination has many folks worried (or elated) about the future prospects of grid-based electric utilities when consumers can get the power they want at home.

Likely too few electric vehicles will show up in Houston in the next year or so to make much of a … More Electric vehicle recharging: Is the energy too cheap to meter?
Michael Giberson In the realm of more-enthusiasm-but-no-more-analysis for vehicle-to-grid (V2G) technology, Fereidoon Shioshansi at the EU Energy Policy Blog asks, “Will V2G Evolve Into A Great Electrical Sponge?” He asks the question, and it is an excellent question to ask, but he doesn’t answer it. Instead we get a little taste of claims made by … More The vast electrical sponge provided by V2G technology
Michael Giberson If you are already a rock star and can’t imagine doing anything else, then “money for nothing and your chicks for free” may be a reasonable characterization of your situation.
