The key purpose of a greenhouse is to provide the ideal growing environment by controlling temperature, humidity, light, ventilation and CO2.
In the ideal environment, quality and quantity of crops are maximised. While sunlight is free, the energy costs involved with delivering the ideal environment are significant – on average, energy represents 40 per cent of the cost of sales. Of this 40 per cent, around 75 per cent relates to heating (typically natural gas, oil, propane, coal or biofuel) with 25 per cent being electricity. The high energy intensity in the greenhouse industry requires an industry focus that ensures the Canadian industry remains competitive and vibrant.
