Last Thursday in California he introduced the world to his streamlined revolutionary Powerwall – a wall-mounted energy storage device which is capable of holding 10 kilowatt hours of electric energy, and even deliver it at an average of 2 kilowatts, for approximately US$3,500.That results in having an electricity cost (taking into consideration installation expenses and inverters) of around US$500 per kWh – lower than 50% current electricity costs,” – www.ewao.com
