Tesla’s game-changing batteries for the home are a page straight out of India’s frugal engineering playbook.
Elon Musk is out to change the world, again. At a recent press conference, the Tesla CEO introduced Powerwall, a suite of batteries designed to enable homes, businesses, and utilities to store up both solar energy and power from the grid. The idea is that by reducing the volatility of supply and demand, the batteries will shrink users’ electric bills by as much as 25 percent. This technology should also make it possible for utilities to increase renewables’ share of the energy mix. And, perhaps most intriguingly, Powerwall theoretically may allow homes to go off-grid completely.
