Electronic Vehicle Battery as Home/Grid Power Backup

Washington Post Climate Advice Columnist, Michael J. Coren, talks about how the battery in your car can become a part of the larger power grid solving short term and medium time frame problems.

Technology already exists to connect your car to your home and use the batteries in the car as a backup to your home incase of power failure. Coren writes about how the electric vehicle battery can currently be used during a power shortage or outage. He describes how to do it, and how much it will costs.

Coren also looks at how when paired with solar power generation (or other home power generation source), the EV battery can help to moderate the difference between peak generation times, and peak usage times. You will need a two way hookup between your house and the grid, and a two way hookup between your EV and your house. This has been a serious concern for alternative energy advocates. A decentralized solution would be almost poetic.
