Yes, I think that's an excellent point. It would probably make sense to have different timelines for each of these, should there be an exemption. I would actually think it makes sense to look at it on a five-year basis. Probably the heating of buildings may need a shorter sunset period, if a sunset period is required at all; and grain drying is going to come later.
