Lethbridge Herald {Newspaper} - 1974-01-23,Lethbridge, Alberta WfdiiMttey, J«nuwy n, 1ffr4-THI LETHMUOOl It couid be one of Canada *s main reaource» Harnessing the sun for energyPaw sucker pacified 1 by Mrs. James Reed, of Norwood, Pansy, a pug owned by Mrs. James Reed, of Norwood, Pa., had a bad habit of sucking her paw, much tike babies suck their thumbs. The dog's family made a search for a "security blanket" for Pansy and presented her a baby’s rubber pacifier. Now Pansy and.pacifier are inseparable. By JEFF CARRTHERS HenM Ottawa Baraii OTTAWA - SuuUm oould turn out to be one cf Cuada't mwt Important enaiy n-■ources in tlie oot-too^tant future, accoNUM to a itill* secret Science Cbuncll itwly on energy. Utlng roof-top tolar cdlec-tort, facing south, it an attractive scbeme for har-natsing solar energy to he«t and perhaps even cool residential and office buildings in some parts of southern Canada, concludes the 900-page energy study which will not be made public until later in the year. In fact, optimized solar space heating systems, when used in combinatioii with ,a back'up aiidUary beater, may already be economically oom-petitive with electrical heating in cities like Toronto. Ottawa and Winnipeg-and probably in .Mtmtreal, Vancouver and Victoria—according to calculations made in the study. The back-up heater is needed to provide heat during sunless days in the winter. perhaps more important for Canada could be a scheme described in the Science Council report ' utlUtari wbweby tbe lowly bnt ilutarían tree would be used at ae ineipenslve collector of tolar «mgy, via phototyn* thesis. Trees grown on “energy itioiu’’ could thw be irnt in steam plants to produce electrical power. There would be several major advantages to tills sdteme over other solar energy schemes. First, it would be less «-pensive—about one percent of the costa of j^roducing tbe same power via direct sw to electrical conversion using solar cells, for example. The trees would be arenew-able resource, unlike coal or oil. And the forests could be managed like tbe huge woodlots cultivated and harvested for pulp and paper or lumber. Most important, storage of energy during the winter would be automatic, eliminating one of tbe weak spots of solar energy in Canada. According to estimates done j Inter-Technology Corp. of irginia, proponent of the scheme, a ^cal 1,000 megawatt thermal electric plant burning wood might need about 1,000 square mikt of renewable forest land. If forest yields couU be laereaa* «d tigmficantly, this mlAt be cut to only 900 square mUet. But one of the drawbacks is that Canadians could be back to the old, despised image al "hewers of wood." In addition, tbe pulp and paper and tbe lumber industrlet would have a big competitor for wood close to big population centres. Despite Canada’s nort»!«r« lattitudes and long, sun-short winters, Canada is well-endowed with solar energy, especially in the southern regions where most of tbe population it concentrated. On the averwe, Canada receives about & percent less solar energy than the U.S. But there is just under twice tbe amount needed to beat and cool an average house, aC' cording to the lienee Council report. In total, Canada intercepts about 0,000 times as much solar energy as its 1972 energy consumption. I'uralng this solar energy directly into electricity, such as by using solar cells, would require about 27 miles square tiada’s pro-lironentsin course, then of land for a 1,000 megawatt et. Tbit would be a lot of in urtwn areat. By centrait, Canada hat tome OlOnnillion acret of ^cth ductive forett, producing «bout Sl,OOOHmillion cuUc feet of new wood each year. If all tbat new wood were converted to electricity in thermal plants, this would satisfy all of Canada’s jecteaenerg] the year aooo there wouk&i’t be any for pulp and paper or lumber. In the space heating scheme, each house would have a special solar collector on the roof, pointing south. Since water freezes in winter, air would be the preferred heat transfer agent in Canada. As oil and gas prices increase, this approach would likely become an “increasingly attractive proposition in certain re^ons of Canada.” according to the Science Council study. It might already be competitive with electrical heating in southern Canadian cities when used with back-up heating during the winter. Tbe scheme would save sufficient fuel to make it ectmomical, thou^ not when com|>ared to oil and gat at todw’s piices. “Tbe problem oi acceptance of tbit method of tpace heating and cooling ramaint. there it tbe Urge capital invettment and the need to have a back-up beating tyttem”. ’Tbere is also tbe aetlbetici of having buUdinn with oollecton on tbe roots, all pointing south. And tbere is the need for the energy storage tank inside. Tbe study noted that there has not beta any significant technical develofHnent of tbe jroach in Canada and tbat it be assessed carefully.
