Document Summary
Energy content: amount of usable energy by weight/volume of any given source. Reliability, storability, flexibility, price, safety/environmental impact, cleanliness, Convenience, all factors that affect choosing energy options for future. Stock resources are non-renewable: some can be recycled. Critical zone requires sustainable/responsible harvesting to prevent exhaustion of resource (ex. 80% of minerals mined are exported in. Potash discovered in canada in the (cid:1005)9(cid:1008)(cid:1004)"s. Acid mine drainage, sulphur dioxide emissions, metal toxicity and leaching into water bodies are major considerations in canada. Canada is a leader in mining uranium. 12-(cid:1005)(cid:1009)% of ca(cid:374)ada"s electricity fro(cid:373) (cid:374)uclear power. Deep disposal in canadian shield, centralized storage above/below ground, storage at nuclear reactor sites all considered as disposal options but all were rejected. Energy consumption expected to decrease in developed countries but increase in developing countries. Dominant sources of energy have shifted over time, wood coal oil. Conventional alternatives to fossil fuels: wood/biomass, hydropower, nuclear power.
