Yes, absolutely. We have had a number of initiatives, for example, the automation project I mentioned that turns off our heavy equipment when it's not in use; and the water project we have with an industry partner near one of our facilities to heat the water using their steam, so that we are using less natural energy to heat the water we need to use in our process at that facility.
We've also done feasibility studies on using renewable energy in our process. Right now, it wouldn't be a question of us not being able to do it technically or the engineering being out of the realm of what we could do, but rather, it would be the upfront capital expenditure that we would have to put into switching some of our sites over to renewables.
