Powerwall is like the automobile of electricity.
(...) Tesla is proposing a similar transformation — the privatization of electricity generation.
(...) what happens to the millions of people who cannot afford the “cheap” $3,500 Powerwall (not to mention the solar panels needed to get individuals off the grid)? In a city like mine (Syracuse, NY), people without access to an automobile are forced to rely upon an underinvested and decrepit public bus system. In a future where households are powered by individual battery walls, will poor communities who can’t afford them be stuck with an outmoded and underinvested grid?
(...) The electricity grid is a profoundly collective #infrastructure. The very nature of the system requires that supply must always be calibrated to the fluctuating demands of society as a whole.
