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

Columbus County (North Carolina) is making plans to work with a private company on a planned co-generation facility that will likely involve greenhouses.
Korean researchers have created a solar cell capable of transmitting the red and green wavelengths of light that plants need for photosynthesis while also retaining the capacity to filter the rest of the energy into electricity that can be used to power a greenhouse.
For greenhouses in the desert to be feasible, they require desalination technology, and therefore significant amounts of power. If new technologies can provide this power in an efficient and sustainable manner, so much the better.
One of the 20 international projects competing at the prestigious Solar Decathlon Europe 2012 is a low-cost, self-sufficient greenhouse based on the principles of zero ecological and zero economic footprints.
Unity Gardens, a group in Indiana, is planning a greenhouse that will use heat from composting.
