The Net-Zero Neighborhood: Advanced Energy Storage and Highly Efficient Photovoltaics Take Transportation Off the Gasoline Grid and Residential Off the Electric Grid

Green Car Congress

The NZN concept relies on high energy density storage systems incorporated into the local grid, as well as efficient photovoltaic generation. If we are going to create some of the batteries, you better be ready to crank out some cycles.” You generate energy locally using renewables. You commoditize energy.
