Uake The Difference" ar energy was often trumpetâ€" by the press in the late 70‘s early 80‘s as the answer to f our energy needs. This was obviously ungqualified, overâ€" tement. Solar energy never s the only answer, and it probâ€" y never will be, however, there areas where it excels and kes practical sense now. ating swimming pools is the st costâ€"effective use of solar rgy in Canada. Manufacturers gas and/or heat pump pool aters will tell you that if the ather is bad a solar system in‘t heat your pool. This is true t misleading. After all, if the ather is bad (cloudy, cold, ning, etc.) most people aren‘t ing to bother to swim in, or at, their pools. It‘s when the ather improves (sunny and rm) that you are going to im, and solar energy is there quickly heat the pool. Solar ergy is free, and solar pool ating equipment is moderate in st, so a typical solar pool heatâ€" system can pay for itself in e of two years when compared natural gas heaters or electric at pumps. lar energy‘s next most cost ective application is for preâ€" sating hot water. Car washes e a good application because ople wash their cars on sunny ays. Laundries too, because ey use large volumes of warm ater. Solar water heating in mes definitely works, but is not ry costâ€"effective using the curâ€" nt solar technology, especially Special Feature by ANDY McKEGNEY when compared to natural gas water heating. If solar is used to displace electric water heating, the payback period is much betâ€" ter than with natural gas, but it is still about ten years. Solar energy‘s cost effectiveness has been improving for heating houses, but this is mainly due to improvements in house energy efficiency rather than better solar technology. Passive solar energy (through proper window placeâ€" ment) and energy conservation should always be used before investing in an active solar enerâ€" gy system. Solar electricity is a wonderful thing. But it is very expensive and only costâ€"effective where regular electricity supply is at least two kilometres away. This means remote locations â€" cottages in Canada (or many other places in thirdâ€"world countries). In Canada, this is not likely to change. If everyone had a solar system to supply them electricity during the day, hydro companies would sell almost no electricity when the sun was shining, and still have to supply all of the electrical demand when it wasn‘t. Solar energy has a valuable roll to play in reducing our use of convention, environmentally damaging, energy supplies. As conventional energy becomes more expensive, and new materiâ€" als make solar systems someâ€" what less expensive, solar enerâ€" gy will become even more costâ€" effective and available in Ontario.

About 20 million people parâ€" ticipated in the events of April 22, 1970. One of the organizers of the first Earth Day, Denis Hayes, promoted the staging of an international festival to celebrate the event‘s 20th anniversary. He contacted environmental groups in 141 countries, including Canada, to creâ€" ate and promote events for Earth Day 1990. An estimated 200 million people participated in tree plantings, educationâ€" al seminars, community cleanâ€"ups, awareness projects, ecology fairs, recyâ€" cling projects, Earth Walks and other Earth Day celebrations. Two million Canadians were among the participants. Although environmental awareness and concern had been growing steadily over the past decade, the success of Earth Day 1990 staggered everyone, including its organizers. Earth Day became the single largest peacetime demonstration in history. The establishment of Earth Day as an annual international event was sponâ€" taneous and global. By May 1990, Earth Day was already receiving calls from communities planning their 1991 events. At the same time, Denis Hayes asked Earth Day Canada‘s president Nigel Seale to take on the international coordination of Earth Day. Seale appointed longâ€"time environmentalist Maury Mason as president of Earth Day Canada, and the national offices were moved from Victoria, B.C. to Toronto. Mandated to nonâ€"confrontational, nonâ€"political environmental awareness and personal Action, Earth Day Canada In 1993, Mason was appointed presâ€" ident of Earth Day International, headâ€" quartered in Vancouver, B.C.

Earth Day continues to be the largest cooperative global environmental orgaâ€" nization, and annually creates awareâ€" ness and participation at all levels of society, in all areas of human endeavor, in 141 nations. Participation grows yearly. In June 1992, Earth Day International helped to stage the first Walk for the Earth in Rio de Janeiro to focus the world‘s attention on public participation in the United Nations Earth Summit. At least ten thousand marchers from all over the world folâ€" lowed Earth Day Canada‘s Earth Flag, signed by 400,000 Canadians, for four kilometres along Copacabana Beach to help promote personal environmental commitment and action. On Earth Day 1993, two million Canadians wore a green ribbon to show their personal commitment to the enviâ€" ronment. Earth Day Canada is commitâ€" ted to individual environmental awareâ€" ness and action. C In 1993, Earth Day Canada launched The Green Ribbon Campaign. Two million Green Ribbons were disâ€" tributed to the public by businesses (including all Zellers stores, SoapBerry Shops, and participating Canadian Pacific Hotels Resorts, offices of The Prudential Insurance Company, Brewers Retail outlets in Ontario, and salons carrying Joico products) and at regional Earth Day celebrations during Earth Week (April 19â€"25)
