Canada's Environmental Voice
Having been millions of years in development, the life forms that thrive on Earth have come up with a trick or two for maximizing sustainability. So what better model could we use for sustainable technology than the Earth’s own natural processes? And one of the most impressive of the world’s […]
This sleek, assertive documentary hinges on two crucial but highly controversial premises. The first is that nuclear power has been distorted by the long shadow of the bombs dropped on Hiroshima and Nagasaki, and the justifiable fear and panic that followed disasters at Three Mile Island, Chernobyl and Fukushima.
It would take more than 200 days to walk across Canada. More if you stopped at New Brunswick’s illustrious Potato World Museum. It’s understandable then, that the quintessential trans-Canadian roadtrip involves a beat up old Honda Civic, rather than a sturdy pair of walking shoes.
Let’s say you want to install a solar panel on your roof but there’s a tree in the way. Trees are great and all, but for the sake of green energy you’d want to cut it down, right? Actually, maybe not. In fact, if you own a tree (just one […]
Energy production is as much a political issue as a technical one, as evidenced by current controversies over sustainable loan guarantees in the United States, proposed pipelines from Alberta’s oil sands and nuclear power in the wake of the Fukushima Daiichi disaster. After all, energy is pursued as a strategic […]
In 2008, the esteemed Al Gore told Obama he should demand that the US move to 100 per cent renewables within ten years. We’re five years on now, but let’s pretend that Obama is just getting around to this memo on his list of things to do. “Oh darn,” he says to […]
Canada has some very successful greenbelts. They promote urban density, reduce greenhouse gas emissions and offer a host of recreation possibilities, among other benefits.
The Canada of 2035 will be a very different place. We’ll be a nation of 43 million people; the GTA alone will balloon to more than nine million residents. It is hard to fathom the changes society will undergo in the next 22 years. Just think back to 1991 (if […]
As greenhouse gases go, hexafluoroethane (C2F6), nitrogen trifluoride (NF3) and sulfur hexafluoride (SF6) are about as obscure as a high school band at the Rolling Stones concert of atmospheric warming. Nobody’s suggesting they deserve top billing, but Ozzie Zehner of the University of California thinks these three GHGs are worthy […]
Powering the world entirely through renewable energies is going to bring about some logistical challenges, as technological change always does.
