Coal cuts good news for growers
Eric Frechette is a progressive businessman who looks for opportunities to build his business using the latest technology and by partnering with leading companies.
As noted in our initial article (December 2010), managing energy use is the first step in the Journey of Energy Excellence for Greenhouses program.
The key purpose of a greenhouse is to provide the ideal growing environment by controlling temperature, humidity, light, ventilation and CO2.

New cogen opportunities in Ontario?
The Ontario Greenhouse Alliance (TOGA) is hosting a pair of information sessions next month on how greenhouse operators may be able to implement cogeneration systems as a result of changes recently announced to the Combined Heat and Power Standard Offer Program (CHPSOP).
Item number four in the 10-step checklist, “Strengthening your Bioenergy Project for Financing,” is the biomass feedstock supply.
One of the common threads running through many of our features of late has been energy efficiency. It’s a prominent theme in this issue. Natural gas prices have been stable for some time, giving growers a little breathing room as they struggle with currency pressures and other input prices.
While nuclear power doesn’t form much of what keeps our industry ticking, radioactivity in the seawater at Fukushima’s nuclear plant that reached 7.5 million times the legal limit after the distressing events in Japan has reignited debate about nuclear’s safety credentials.
In the second article in this series (June 2010), we looked at the feasibility of Combined Heat and Power (CHP) systems for horticulture.
The Ontario government has a problem – how to replace the electricity currently generated by coal-fired generating units once coal is phased out as a fuel source in 2014.
In the previous two articles, the growing interest in carbon dioxide (CO2) fertilizing has already been discussed.
Geothermal energy makes sense for today’s greenhouses, says Dr. Mory Ghomshei of the University of British Columbia Institute of Mining Engineering.
In the previous article (April 2010, pg. 12), the principles of a CHP (combined heat and power) system for the horticulture industry were described. In this article, we’ll elaborate further on the feasibility of such systems. Please note: the figures used are based on conditions in the Netherlands and should be adapted for the conditions in Canada.
