Answer to California’s San Onofre nuclear power plant closure could be clean energy

California now has less of an energy supply … or does it? I ask because the San Onofre nuclear power plant, located in northwest San Diego County, is no longer producing electricity – it is offline and it is to remain that way. Even so, this in no way means demand for electricity in state is less. So, … Read more

CATS: Value-packed ‘Megaflora’ trees absorb pollution, produce energy

Number 19 in the Clean Air Technologies Series. Fuel being a central and huge and important element in the energy production story, I doubt very many people realize there is at least one fuel, an alternative fuel, that can not only produce energy but help clean air, soil and water as well.

Efforts to lower air emissions from marine vessels in Canadian waters laudable

It’s always heartening to learn when new measures are being implemented to reduce emissions.

eMission control – Focus: Airways

Global air travel is not receding. In fact, in several places triple-digit percentage increases are not uncommon. Katherine Rowland in OnEarth magazine in “Infographic: Flying the Friendlier Skies,” writes: “In emerging economies, the growth has been dramatic: between 2007 and 2010, passenger volume in China increased by almost 50 percent — another 84 million fliers. … Read more

CATS: Grand Canyon Railway a ‘Lean, Clean and Green’ machine

Number 14 in the Clean Air Technologies Series. If I mention the National Park Service (NPS) what draws to mind? Conjured up images of environmental sustainability? How about awards presentation? Probably neither, correct? First order of business here is the subject of environmental stewardship. I ask: is it not the preservation of open spaces, scenic vistas and the … Read more

CATS: Piezo-electric transducers – one more renewable resource

Number 12 in the Clean Air Technologies Series. I don’t consider myself to be an inventor or designer, but in the late 1980s I came up with what I thought was a feasible idea: make use of piezo-electric devices to generate electricity. The specific application I was going for was in the railroad realm whereby … Read more

The renewables challenge: Fifty percent reliance by 2050?
