When it comes to things like barn heating.... If you look at just common residential practices, when you ask people to improve the efficiencies in their homes, you get better insulation, more efficient furnaces and those kinds of things.
Water heating is also important in a lot of livestock operations—dairy operations and so on. It's a package that I think is available. At the same time, you have to realize that a lot of modern agriculture is already at the top level, with well-insulated barns, using efficient heaters and everything else, so recognize that.
If you're using the best technology available, it's hard to improve on it. I think that's some of the frustration farmers are feeling. There are always improvements that can be made, but when you're paying the carbon tax on something like all your natural gas, and you're already at the top level of barns—your barns are brand new and your furnaces are brand new—then the fact that you're still paying the carbon tax is very frustrating for producers.
