Co-gen or tri-gen are absolutely fabulous. It's not permitted in British Columbia because.... Well, it's permitted, but you can't sell the excess electricity to the grid. I know that Ontario has taken great advantage of that. We do recognize the value in B.C.
Our biggest thing for greenhouses is that if we produce the CO2 on site rather than trucking it in, it's a more efficient use. There are alternative fuels, for example, biomass, and many of my greenhouse members have biomass boilers, but unfortunately, you can't get CO2 off it economically. A lot of research has been done on it already. They tend to lean towards natural gas so they can get the CO2 they need.
