ENV250Y5 Lecture Notes - Lecture 26: Bruce Power, Tight Oil, Tight Gas
Document Summary
Lecture 16. 2 - hydraulic fracturing and nuclear energy. ^ cleaner source of energy (reducing ghg emissions) Rock (gas or oil) is fractured/split by high pressure liquid. Shale gas - natural gas trapped in shale rock (clay minerals) Tight gas and oil - natural gas found in sandstone and limestone. Tight oil - that is found in shale or sandstone (aka. Water pollution - they don"t close areas, etc. Water quantity - 2to7 million gallons for each well. Natural gas produces half the co2 emissions as coal. Neither a fossil fuel nor a renewable ergy. Energy created from nuclear process = uranium (natural process) Nuclear power plant - usually beside a water source. Around 440 nuclear power reactions in 30 countries. 15% of canada"s energy is nuclear - supplied mostly from ontario. 5 stations - pickering (2), darlington, kincardine (2) - bruce power. 2009, spill of 200,000 litres of nuclear waste right into lake on.
