187. Growing tomatoes with waste energy


A greenhouse in Ontario is using waste heat from the stack of an ethanol plant to grow tomatoes and that’s only the beginning of this amazing story of industrial symbiosis. Corn comes into the biorefinery and produces ethanol, industrial alcohol and corn oil and virtually all of the waste from the plant is also used as well.

139. The first certified passive house in Saskatchewan

We visit what will be the first certified passive house in Saskatchewan, Canada. This is somewhat ironic, because the first concept passive house ever was built in Saskatchewan in the 1970s by passive house pioneer Harold Orr. Meet Harold and see this amazing home!

Energy audits are often supported by municipal or provincial energy efficiency programs because they provide a strategic recipe book for all future energy efficiency improvements to businesses or homes. It provides hard, cold facts about return on investment for each change you are contemplating. It might be the best money you spend. Here, Rob Gawreletz inspects the attic insulation and seals in a home audit by CReturns, in Edmonton, Alberta. Photo David Dodge,

138. Energy efficiency coming to Alberta, at last!

This week, we visit a conference on energy efficiency that’s looking to to change Alberta’s current lack of program support for energy efficiency initiatives.

Edmonton's new carbon neutral net-zero garage suite is full of sensors and will be part of Godo Stoyke's PhD lifecycle assessment of the home to determine if energy efficiency and solar energy production can make not only the operation of the home carbon neutral, but whether it can also offset the carbon used in materials and construction and decommission.

137. Carbon neutral laneway home–first of its kind

This carbon neutral home has a solar wall, solar PV on the roof and a unique energy storage system that heats this innovative garage suite when the sun doesn’t shine!

Visiting the Kinney Earthship, in the dead of winter on the Canadian prairie landscape north of Lethbridge, Alberta does invite comparisons with the lunar landscape! So much so it inspired photographer Steve Nagy to create this selfie in the middle of the night on a fine winter day. And in fact the number one question the Kinney's get about their Earthship is how does this passive solar heated home work when it's -30 degrees celsius.

136. Earthship living in a cold Canadian winter

How does a passive solar heated Earthship fare in the long cold Canadian winter. This week we return to a familiar place, the Kinney Family Earthship, to see how it holds up in the middle of a cold Canadian prairie winter.

Peter Amerongen is one of the acknowledged grandfathers of the net-zero home—a home that produces as much energy as it consumes. Using his secret formula for insulation you can make a net-zero home in the most northerly city in North America. Photo David Dodge,

132. Insulation 101: One builder’s secret blueprint for a net-zero home

The era of net-zero homes is upon us. These super-efficient homes use rooftop solar energy production and smaller, electric powered heating systems such as air source heat pumps to produce as much energy as they consume. But the real secret is insulation. Peter Amerongen shows us Habitat Studio’s unique formula for insulating the heck out of a home.

The incandescent light bulb phase-out is akin to getting rid of leaded gas, CFCs or the Ford Pinto. It is unequivocally a good news story. Learn why this week at Green Energy Futures.

54. The amazing earth tube cools office tower

Earth tubes are a simple, passive geothermal system that takes advantage of the earth’s constant temperature below the frost line. By drawing fresh air for your building through an earth tube you pre-heat or pre-cool your air depending on your needs. This saves you a ton of money, according to architect Tang Lee an earth tube system can save you up to half of your ventilation heating costs. At the Epcor Tower it saves the building $50,000 a year.

37. Landmark: How to make a more energy efficient home with robots

Landmark Homes builds super energy efficient homes in a factory. Not only is this process more energy efficient – it’s also about 10-12 tonnes of CO2 more efficient. The homes they’re building are understated energy efficiency lions.

35. Reimagine your office building – Servus did it!

When Servus Credit Union acquired an old Dell call centre and decided to turn it into their corporate headquarters it was a bit of a fixer-upper. It was a concrete tip-up building originally designed for the climes of Oklahoma 3,000 km south of Edmonton. Well, they decided to keep the building but go full-out on a creative renovation to make a better building.

25. Waste to willows

Learn how a small rural Albertan county is treating it’s waste in a more environmentally responsible fashion and growing their own substitute for natural gas. They pump the effluent from a waste lagoon into a densely planted stand of willows. Willows like moist soil, grow fast and grow easily in our climate. That willow is then chopped down every three years and can be used for wood, heat or compost. In Camrose, they’re using it to heat their main county office.

When Ted Wolff decided to buy a 55-year-old bungalow in the west end of Edmonton he knew he wanted to renovate. He also knew that his home wasn’t necessarily the most energy efficient, that’s when he brought in C Returns and Godo Stoyke and they called for an energy audit. By getting an audit Wolff will be able to make the best decisions when it comes to allocating money and resources to make his home more energy efficient.
