Tesla Motors Inc. CEO Elon Musk announced Thursday that his company might change what kind of batteries you use every day and how you power your home.
At the company's design studio in Hawthorne, California, Musk unveiled a new kind of battery that would support Tesla’s mission to create pollution-free technology.
"Our goal here is to fundamentally change the way the world uses energy," Musk said. "We’re talking at the terawatt scale. The goal is complete transformation of the entire energy infrastructure of the world."
Musk introduced a home battery called Powerwall, a rechargeable lithium-ion battery that can be mounted on any surface. It stores power, minimizes electricity use during peak hours and can help users get off the power grid by using solar energy, though it can be used when then sun isn’t out. The battery, which is already for sale for between $3,000 and $3,500, will start being delivered to homes at the end of summer.
On the Powerwall website, Tesla writes: "The average home uses more electricity in the morning and evening than during the day when solar energy is plentiful. Without a home battery, excess solar energy is often sold to the power company and purchased back in the evening. This mismatch adds demand on power plants and increases carbon emissions."
In effect, this could allow homes to run entirely on solar energy, although it does integrate with power grids “to harness excess power and give customers the flexibility to draw energy from their own reserve.”
Tesla is largely known for its innovative electric vehicles.
