Freezer might be a viable alternative actually. Especially if you use a heat pump and use the “waste” heat to heat buildings in the winter. Or, even with greenhouses, a ground source heat pump that stores thermal energy in the soil in the summer and extracts it in the winter could potentially also work. Heat pumps can be up to 5x more efficient than resistive electric heat.
The thing is, to my knowledge, the only fresh produce available locally in Quebec in the winter is greenhouse grown because it’s literally too cold for any edible plant to grow in the fields. Broccoli isn’t special in this regard because nothing would be in season.
To be fair the assignment wasn’t really meant to actually inform people what they should do. It was meant to test our ecological impact assessment and data analysis skills that we learned over the term, so they probably did pick a relatively simple example (still with real numbers though).
