We have a number of contracts where we have purchased green electricity. Right here in Ottawa we have a substantial contract in place for that, and certainly in Alberta, where there is a supply as well. With the last contract we put in place there, 85% of the power that Public Works was using is coming from green sources.
In terms of generating our own power, it's interesting. As Ontario starts to...it looks like changes will be made to allow someone to feed into the grid. We have had conversations with some people who are interested in pursuing that in government buildings. We don't have concrete plans right now, but it's something we're interested in looking into further.
