These are early days, and any time you launch into something as significant and new as this, there are entry barriers from a pure economics standpoint.
We're looking for some seed money and some support so that investors like us who are investor-owned are actually willing to step up and make these investments and be helped along by some of the immediate economics. Once commercialization starts to take place and you start to get momentum, the actual cost of these systems will decrease in the long run. So that is one of the issues.
The Burlington service centre is a good example. It cost us about a 25% premium to build it to gold LEED standard. When we did the economics, the actual payback is there, but you have to front-end the capital to get the long-term operational savings to make the economics work. So there is a front-end cost to this.
