An earthship is an off-grid home that produces its own energy, captures its own water, treats its own wastewater, grows its own food and passively collects the sun's energy for heat. That's the idea, anyways. But ever since the Kinney Earthship was built in the summer of 2014, Duncan Kinney has received many emails about one particular subject: how does it hold up so far north?

A passive solar greenhouse in Invermere B.C. is making people across the continent sit up and takes notice. What is a passive solar greenhouse? Don't they already use the sun's energy? Well, yes, but with the traditional Dutch glass box greenhouse design all that heat leaves once the sun goes down.
When you walk into the Truly Green greenhouse the smell of tomatoes is heavy in the air. Their location across the street from Greenfield is no accident. The plan is to take nearly all of the waste heat and leftover CO2 from the ethanol plant and use it to grow tomatoes.
In Dawson City, one step away from the arctic circle, we are working to promote more local food production. Here, more than anywhere else, food matters.
