Google to invest on a massive undersea power spine

Google is funding on a massive undersea power cable along the East Coast that's designed to ferry clean power from offshore wind farms to the country's most populous region. The project is planned to start off in southern Virginia and ending in northern New Jersey with the cable laying on the sea floor some 10 to 20 miles offshore and it is estimated to carry around 6000 MW of electricity(enough to power 2 million houses).

It is also probable that the high voltage, DC-current cable will attract wind farm developers to construct farms off the East Coast. As we know, offshore wind has several advantages to onshore wind, including steadier and stronger breezes and a location that's out of sight and earshot from most people. The only drawback is it's expensive, and there are currently no commercial offshore wind farms in the United States.

Besides cost, another major obstacle to building any type of wind farm has been transmission - how to get the power from the often remote places where the wind blows, to the cities were it's consumed.

Goggle is an investor in this project and it is run by the transmission company Trans-Elect. It has a 37.5% stake in the cable. Google first announced its involvement in the project last October.
