I guess this is my question. Whether it's the cost to consumers or the cost to industry, an increase in energy efficiency in a marketplace that I believe, as economists, you would imagine going up in terms of prices for primary energy.... I've seen few predictions from economists that say the price of a barrel of oil in 20 years will be much less than it is now, or a kilowatt of electricity, or natural gas. Would efficiency not then be a cost not incurred by industry or by individual Canadians if we became a more efficient economy, if our individual use of energy as citizens, but also our use as an economy, were less?
