Concentrated Power

Concentrated Power. A 7-gram or .25 oz pellet of uranium, has a much energy as: - 1,780 pounds of coal (uranium is 113,920 x’s more concentrated) - 149 gallons of oil (uranium is 61,600 x’s more concentrated). Nuclear waste.

  1. Concentrated Power A 7-gram or .25 oz pellet of uranium, has a much energy as: - 1,780 pounds of coal (uranium is 113,920 x’s more concentrated) - 149 gallons of oil (uranium is 61,600 x’s more concentrated)

  2. Nuclear waste • The total waste from all of Canada’s historical 27 reactors, since their enactment (start dates between 1971 and 2003 to date) is about 300,000 ft3. • The total waste would; • cover a CFL football field to about 3.4 feet deep • fill an Olympic swimming pool to the depth of 22 feet

  3. Costs of Different Energy SourcesCents per kWh Source: Canadian Energy Research Institute (CERI), September 2006

  4. Life-Cycle EmissionsTons of C02 per Gigawatt-HourFrom mining (manufacturing), to operations, to waste management. Source: “Life-Cycle Assessment of Electricity Generation Systems and Applications for Climate Change Policy Analysis,” Paul J. Meier, University of Wisconsin-Madison, August 2002 .

  5. Wind Power:A “Vestas-V80” in Saskatchewan

  6. SaskPower’s Centennial Wind Power Facility • 83 “Vestas-V80” units creating 150 megawatts of power on 7,500 acres of land (or 30 km2 or 11.7 miles2) • Footprint is 0.02 megawatts per acre • Each unit; • is 351 ft tall , or 107 meters, or over 30-stories • weighs 222 tonnes or 489,510 pounds • has 3 x 39-meter blades, with tips moving at speeds up to 256kms/hr • needs win 15 km/hr to operate, with full power at 50 km/hr • 2nd largest facility in Canada when opened in 2006

  10. Footprint of Wind vs. Nuclear640:1 • Bruce Power proposal for AB and “eluded to” for SK is, for example; • 2 Areva EPRs • 3,200 megawatts from a 250-acre facility (1 km2 or less than a ½ section of land or ½ mile2) • Footprint is 12.8 megawatts per acre • To get 3,200 megawatts from wind, at same scale as Centennial, (0.02 megawatts per acre) it would require; • 1,771 turbines covering 160,000 acres • or, a farm of turbines 2 kms wide, stretching from Regina to Prince Albert.
