Green energy giants Tesla have announced a new range of low-cost solar batteries that they have billed as the ‘missing piece’, in the development of sustainable energy.
The pioneering batteries will retail at $3, 500 in the US, and have been hailed by Tesla founder Elon Musk as a ‘fundamental transformation in how energy is delivered across the earth’.
The smallest of the two, the ‘Powerwall’ is small enough to be hung inside a garage, and can store up to 10kWh of energy from wind or solar panel, and up to eight batteries can be stored in a home.
The stored battery reserves can be used during grid outages, when sunlight is low, or at times of peak demand.Tesla’s “Powerwall” was unveiled on stage yesterday (Picture: AP Photo/Ringo H.W. Chiu)
And the larger ‘powerpack’ model can be used on a national scale, to pump electricity into the grid during periods of high demand.
Speaking as he unveiled the new Powerpacks on Thursday, Musk claimed that about two billion of the batteries could hold enough electricity to power the entire world.
‘That may seem like an insane number’, he said.
‘But this is actually within the power of humanity to do.
Musk, who previously played an instrumental role in the development of PayPal, has also founded private space company SpaceX, and is reportedly developing Hyperloop, a high-speed public transportation network.
