I agree with you, Mr. Raymond, that the 16 000 commercial aircraft which fly the sky today, and the 700 to 800 additional ones each year, will never run on electricity.
However, 40% of Canada's energy is spent on heating and cooling buildings. Even here, in Ottawa, we have just discovered something extraordinary with regard to lighting: we will not spend more energy on lighting.
However, your list does not include geothermics, which uses electricity. In my view, far beneath the earth's depth in Canada there is hot and cold energy, something which we can never get from the oil sands. Indeed, this is an extraordinary source of energy. We could cool buildings and each of our country's cities. I know Montreal and Quebec City very well—perhaps there are others—which are built on bedrock. Geothermics could provide energy not only for 30 or 50 years, but for 200 years, yet you don't mention it at all. I'm surprised.
Your list does include wind energy, solar energy and biomass. These are not necessarily better sources of energy; but geothermics is a used source of energy which could be well adapted to large buildings. It uses electricity, and because of this the electricity needs of buildings could be reduced from 40% to 10%, since that is the percentage of electricity needed to effectively harness geothermic energy.
