For individual homes, I'm just trying to understand your question. A geothermal heat unit for an individual home is an option, supplemented by solar and wind power, and so on. Mostly what we're looking at through the Green Municipal Fund would be district systems. I think you've heard about Okotoks, for example. That place would be something that we would look at from a green municipal standpoint.
But there is technology available for the homeowner that they could either apply in a new home or an existing home to improve their heating and cooling systems, and that would result in environmental benefits.
