As we move closer to more sustainable energy infrastructure, Tesla, GE (General Electric) and LG Chem, are developing various battery-storage technology solutions, which could in theory provide a back-up system for consumers during blackouts.
Will we see the "Powerwall" and others, become vital part of our homes, here in the UK?
Of course this is a new, and ever evolving technology, with new innovations, so there is always a danger that the technology is quickly superseded by the next big thing. What will supersede the rechargeable lithium-ion battery unit?
The device would allow consumers to get off a power grid or bring energy to remote areas that are not on a grid. Tesla plans to start shipping the units to installers in the US by this summer. In a highly anticipated event near Los Angeles, Mr Musk said the move could help change the "entire energy infrastructure of the world". "Tesla Energy is a critical step in this mission to enable zero emission power generation," the company said in a statement. The rechargeable lithium-ion battery unit would be built using the same batteries Tesla produces for its electric vehicles, analysts said. The system is called Powerwall, and Tesla will sell the 7kWh unit for $3,000 (£1,954), while the 10kWh unit will retail for $3,500 (£2,275) to installers.
