SCH 4U1 Mr. Dvorsky Mercredi 16 Novembre The Energy Debate SCH 4U1 Mr. Dvorsky Mercredi 16 Novembre

The Alberta Oil Sands Alberta Oil Sands – type of fossil fuel deposit . The sands contain a mixture of sand, clay, water, and a viscous form of petroleum Making fuel from oil sands requires energy for refining. The process generates 2-4x the amount of greenhouse gas per barrel of final product compared to conventional oil

As it stands now, our economy relies on energy as an export The oil sands employs 500 000 Canadians Great potential for growth in development of the oil sands If we move towards more greener energies, we will lose this export and damage our economy. If we continue to develop this export we risk tremendous damage to our environment.

Power from nuclear fission Heat is used to boil water and the resulting steam drives a turbine. The spinning turbine drive generators that produce electricity. Most widely used nuclear reaction is fission Uranium-235 is used

Bombardment with a neutron induces fission ΔH = 1.9 x 1010 kJ/mol More neutrons produced, which can yield more reactions

Nuclear fission Canadian reactors (CANDU) use natural uranium (0.7% uranium-235 and 99.3% uranium-238). Arguments for: very little air pollution – does not contribute to greenhouse or acid rain. Also uranium is cheap. –with fast reactors, uranium will likely never run out.

Arguments against: -possible accidents (Chornobyl), or as the result of natural disaster (Fukushima Daiichi)
