There are issues around ensuring that there's information available to households, to businesses, to industry, and various other ways—through research and technology and so forth—to try to grow the potential for this industry over time.
Other things are happening in the economy that are trying to develop and foster the market for this. Some utilities and some provinces are contemplating advancing some of the moneys which homeowners can repay through their utility bills or through their tax bills or whatnot. Those are sensible investments for households to make. They typically generate good payback, in three or five years. There would be an expectation at some point that after considerable government support, the market would take over and pursue those opportunities through other means.
