That's a great question.
I might just note, in case it's of help as well, that when we look at total expenses on farm, heating fuel tends to be a very small percentage for most farms. It's around one per cent or less, actually. Greenhouses tend to much higher in energy use, of course. I say this just in case it would be helpful to the committee.
In terms of alternatives, we have a suite of different programs. Marco had touched upon the agriculture clean technology program, which looks at both R and D as well as adoption on farm. We have our AgriScience program, which is an industry partnership where we look at opportunities for things like more efficient poultry heating in barns.
There are different ways that we look to develop those alternatives.
