Since the onset of the pandemic, we have become increasingly aware of how fragile the Qu\u00e9bec food supply is, given the reliance on importing fruits and vegetables. To become more self-sufficient, we need to increase local greenhouse production, even in winter. The challenge lies in finding the energy to heat them. Professor Jasmin Raymond<\/a> of Institut National de la Recherche Scientifique (INRS) sees this as an opportunity to develop the province\u2019s geothermal resources.<\/strong><\/strong><\/p>\n\n\n\n

To grow fruits and vegetables year-round in Qu\u00e9bec, farmers have to operate large-scale greenhouses, but hydroelectric power alone would not be enough to heat them. \u201cIn periods of extreme cold, demand for electrical power would require more generating capacity than Hydro-Qu\u00e9bec can provide. That is why greenhouses are heated mainly by natural gas,\u201d says Professor Jasmin Raymond, a geothermal specialist at INRS.<\/p>\n\n\n\n
