Sure, I can speak briefly to that.
Primarily, on the state level there are currently solar programs that provide financing mechanisms and rebates for individual homeowners who install photovoltaic systems on their homes. And in talking to people in the solar industry itself, they really have lived and died on the extension of these state-based solar tax credits for the last number of years.
The ones I've spoken to certainly would prefer to see a system similar to what Germany adopted, a feed-in tariff that made the sale of electricity produced in individual home-based systems back to utilities financially attractive. And that would cause the expansion of home-based solar systems in the U.S. the same way it did in Germany.
As far as geothermal installations go, I'm not aware of any particular incentive programs to push those. I am aware of efforts to push that industry, though. And one of our partners, the steelworkers union, through one of their career development centres, has even created a program to teach people how to become geothermal heat pump installers in their own homes as part of an effort to preach energy efficiency and self-sufficiency.
