$100 Billion for a Smart Grid

Smart Grids are basically about making the distribution of power smarter through improving the transmission system. Think of driving when traffic signals are synchronized, verses not for movement of traffic. The current transmission infrastructure has challenges and is in the wrong place for carrying alternate energy. The windy areas that are prime for wind farms, don't have the transmission lines needed to send the power to the area that needs the power. My thought is a DC Power System. The key issue, as this article mentions, Can the DOE stimulate the smart grid? , is the incentives that utilities are given. If the improvement of transmissions lines are not given the right incentive they will be starved for capital. And with the US having a very decentralized power production system, it makes it even more challenging.
