Gaining your edge

Energy Edge is an initiative of Greenhouse Canada magazine aimed at turning what is a liability for most growers – fluctuating energy costs – into a competitive advantage. With energy accounting for as much as 40 per cent of the operating costs of many greenhouse operations, small and steady improvements on this front can move the needle in a big way on the bottom line. Energy Edge will look at new technologies, innovative projects, case studies of growers finding their own Energy Edge.

You can read about it in each issue of Greenhouse Canada, but we’ve also created this dedicated microsite. Here you can find regular news items on the subject, new technology and products, video, and in-depth archives on the subject.

We’ll also produce a bi-weekly enewsletter to keep you up to speed on what we’re covering. It is free to all Greenhouse Canada digital subscribers. You can sign up for it here.

If you want to add to the conversation, please drop us a line and let us know about your project, technology, services, or concerns at energyedge@annexweb.com.

Renewables

The largest solar-roofed greenhouse project on the planet is now complete in Italy. The first crop is expected in October 2012. The 134 greenhouses are located on 66 acres near Cagliari in the region of Sardinia.
Solar panels alone will power a new greenhouse at Southern Polytechnic State University in Marietta, Georgia.
Running of the sprinkler pump, cooling of a building and the greenhouse fans at The Mustard Seed near Chaska, Minnesota are all being powered by the wind. Owner Mark Halla took advantage of federal grants to install the power generation system and expects payback in five years.
Federal Health Minister Leona Aglukkaq announced this week that her ministry will initiate an in-depth scientific study into possible adverse effects of living near wind power projects.
Three years ago, the Syndicat des producteurs en serre du Quebec (the province's greenhouse growers' union) chose Les Serres Verrier in Saint-Joachim-de-Courval to install a new biomass heating system, as part of the Vitrine biomasse project (Biomass Showcase).
