In the third part of this four part series on solar energy we will continue to examine an integral part of energy history: computer simulation. Faced with the combined uncertainty of a unstable oil market and a desire for new solar technologies, the government searched for and a means of managing these risks. In this situation, computer models provided policy makers with a foundation, albeit a shaky one, for their decisions.

The Meadowvale Solar Home in the winter of 1977. This experimental home was built to test the application of solar heating technology in Canada. While a success, it provided heat far less efficiently than the WATSUN model calculated and experienced many more technical problems than the model projected.

Two engineers, K.G.T Hollands and J.F. Orgill from the University of Waterloo devised the computer simulations that determined Canada’s plans. The work of these two engineers highlights the diverse support that solar technology and environmentalists’ calls for alternative development received in the 1970s. The two were members of the Canadian Solar Energy Society, which formed in 1975 to support solar development. Intrigued by solar technology’s bright future, this group of scientists, engineers, and business people studied the technology, shared information, and generated interest in solar and other renewables. The society had a substantial impact on solar development. It counted a number of ministers among its supporters and attracted a stream of government analysts and advisors to its annual meetings and workshops throughout the 1970s. Continue reading
