British Columbia could open new industries and create hundreds of thousands of jobs by turning its attention to the world's $200-billion power technology industry, a report submitted Monday to the B.C. government says.
The report says global climate change, and waning production of oil and natural gas, will throw a wrench into 90 per cent of the world's present energy supply -- describing a fossil fuel shortage as "imminent."
B.C. residents are "solidly behind sustainability" but the province must increase its commitment to research and development of lower-cost alternate energy technology, the report from the B.C. Sustainable Energy Association says.
Wind, tidal and solar generation all offer significant opportunities.
"If B.C. makes this transition first, it will be in a position to be a global hub for one of the largest market opportunities in history," the report says.
The association estimates as many as 400,000 temporary, part-time and full-time jobs could be created and adds that B.C. could more than double its present hydroelectric capacity without building another major dam.
"Our analysis shows that B.C. has the potential to generate 84,250 gigawatt hours of sustainable, renewable energy [including efficiency savings]," says the report, which was submitted to the government's committee on alternative energy and power.
The panel is co-chaired by Environment Minister Barry Penner.
Penner said he hasn't had time to review the report but said that, "as Minister of Environment I can't help but be interested in ideas that support sustainable solutions."
Penner noted that B.C.'s alternative power technology sector already includes more than 60 companies providing 3,000 jobs and generating $700 million in annual revenues.
The report follows a 2002 BC Hydro study that listed the province's green energy resources, but focused on sources that are relatively close to the cost of hydro generation.
BC Hydro's generation cost is 2.5 cents per kilowatt hour (kWh) at its existing "heritage" hydroelectric facilities.
The sustainable energy association estimates micro-hydro at between four and nine cents per kWh and six to 12 cents for wind.
Estimated generating costs for tidal power, a fledgling technology, are 11 to 25 cents per kWh.
Solar power is 60 cents to $2 per kilowatt hour.
Association executive director Guy Dauncey said in an interview that Hydro could structure its electricity rates in a way that supports alternative energy, as several U.S. states have done.
"Everyone who pays a BC Hydro bill would pay an extra, say, half-cent per kilowatt hour which supports the development of new emergent technologies," Dauncey said.
He added that Germany, which has "the same sunshine ratio as British Columbia," is going full-tilt on solar power development.
Mary Hemmingsen, BC Hydro manager of power planning and portfolio management, noted the Crown corporation is compelled by the B.C. Utilities Commission to maintain the lowest-possible electricity prices for its customers -- who enjoy the third-lowest electricity prices in North America.
"We probably agree that B.C. has some really significant green resource potential," Hemmingsen said. She also cautioned that while tidal resources are significant, the technology is, as yet, unproven.
SWITCHING HOW WE THROW THE SWITCH:
The B.C. Sustainable Energy Association says the province has huge green power potential that could provide not only renewable sources of energy but could aso stimulate economic development and employment.
