>HVDC and UHVDC is getting fairly cost effective now, so I don't think we'll need huge government subsidies to see adoption there, and it can be driven by utilities. I've been told by people trying to build these things that there are some pretty terrible incentives discouraging HVDC. States without access to good wind sites may still oppose HVDC because they would prefer to build either different power sources or less efficient windmills in their own state to capture the tax revenue (or to use federal subsidies that might go unused), so they prefer not to be able to buy power form a farther away state. And even the reverse can be true. Localities with extremely cheap energy prices can sometimes oppose a HVDC market expansion because if local sources were able to sell to more consumers it would raise their local prices (the market changed over time or was estimated incorrectly, etc).
