Many opponents blowin' in the wind

Canadian governments are getting on the wind-power bandwagon in a big way, but when it comes to building a wind turbine in the backyard – literally, in some cases – opposition quickly materializes, even among some environmentalists who say they support wind power.

Bottom line – wind hasn’t yet caught on, and may not in the foreseeable future, to the degree that environmentalists originally hoped.

The corn isn't green

Alberta is an environmental pariah for its tar sands, which are just about the world’s worst emitters of greenhouse gases, but Alberta’s neighbours to the east – Saskatchewan, Manitoba and Ontario – avidly promote a competing fuel with proportionately much greater emissions.

The federal government also has been promoting this souped-up greenhouse gas generator, ironically touting it as a Future Fuel that can help meet the country’s Kyoto targets. But this competitor can only make matters worse.

The Carbon Harvest

(February 13, 2008) Global warming is the biggest threat that farmers face, and not because carbon dioxide threatens their crops — carbon dioxide is actually a boon to crops, and increases yields. Continue reading

Coal enters rehab

(Dec. 7, 2007) Coal, chock-full of substances of known toxicity, epitomizes dirty fuel. The perils in coal burning – and this is an abbreviated list – include fly ash and heavy metals such as arsenic, lead, mercury, sulphur., vanadium, beryllium, cadmium, barium, chromium, molybdenum, zinc, selenium, radium, uranium and thorium. If these substances and their byproducts are not controlled in coal burning, to keep emissions within safe levels, human health and the environment can suffer. Continue reading

Hydrogen: Running energy policy on hype

Californian Sam Leach knew that hydrogen was a winner. Near the time of the first Middle East Oil crisis in the early 1970s, Leach convinced gullible American investors to give him US$1-million on the strength of his claim that he had built a car that used ordinary water as a fuel. His "invention" used electrolysis assisted by his secret catalyst. He claimed to be able to decompose water into oxygen and hydrogen, and then use the hydrogen as a fuel to run the engine and generate more electricity than he started with. The claims turned out to be false, but by then Leach and the money had moved on. Continue reading

LEDs signal energy revolution

While governments have diddled for decades in the energy marketplace, subsidizing a 500-megawatt nuclear plant here, a 5,000-kilometre Arctic pipeline there, the big energy gains have come via pint-sized innovations in conservation and energy-efficiency. This decade, the biggest little gainers on the planet are LEDs, or light-emitting diodes, those gizmos that first entered the public consciousness in the 1970s through calculators and digital watches.
