On the technology side, the two companies intend to develop smart-grid technologies, plug-in hybrid vehicles, and enhanced geothermal systems, where underground heat is converted into electricity.
Smart-grid technology lets utilities more efficiently manage electricity on the grid. And through smart meters and in-home displays, it lets consumers better understand and control home energy use.
GE and Google will work on utility software to make the grid more efficient, and on software for home smart-grid equipment, Immelt said.
