That need for balance is true of electric power grids, too. Spiking demand for electric heat collided with supply problems created by frozen natural-gas equipment and below-average wind-power production. Packetized energy management (PEM) allows the power grid to flexibly handle a varying supply of renewable energy.

Its like having a second fuel tank that you always use first -- only you fill up at home, from a regular outlet, at an equivalent cost of under $1/gallon.

Despite this, a 2003 EPRI study , assuming only $2/gallon gas , zero buying incentives, and a PHEV premium of $3-$5,000 more than standard hybrids, shows that the total lifetime cost of ownership for a PHEV will be lower than that of any other vehicle type -- so the payback will be there. Whats Vehicle-to-Grid and why would I like it?

Small long-term evaluation program, including modeling of vehicle-to-grid building benefits and economics, begun with Southern California Edison, joined by EPRI, other utilities, US DOE. Plug-in hybrid electric vehicle technologies are not yet competitive due primarily to the high cost of advanced batteries. Batteries not ready.
