Forget the grid. All you need is a battery. Billionaire businessman and renewable energy guru, Elon Musk, recently unveiled the Powerwall, an energy storage device that could break our dependence on coal based energy.
This wall-mounted device, marketed toward residential consumers can hold 10-kilowatt hours of electrical energy, potentially bringing household energy costs down to six cents per kWh. To top that off, Musk plans to manufacture the batteries in the United States.
The Tesla Energy System is poised to change the world. In addition to the home battery, there is an industrial system called the Powerpack that can supply 100 kWh storage. One hundred of these units grouped together can form a 10-megawatt storage unit. This system could provide competitively priced energy for entire communities. According to an article published by EWAO, Musk says the United States’ entire power grid can be replaced by 160 million of these industrial units. A mere two billion of the units could meet the world’s electricity needs.
Musk has been compared to Henry Ford, taking the innovations of others beyond what they ever dreamed. China is also developing similar technology that could lead to robust capitalist competition. These advances put an end to the arguments that renewable energy is not sustainable.
With Musk’s introduction of storable, renewable energy, there is no other direction to go except forward into the future.
