Harness the Wind

Wind HARNESS THE Rotator Diameter: 126m A.P. Design: Olena Sullivan Canada is the 9th largest producer of wind energy in the world with a current installed capacity at 6,201 MW - roughly 2.3% of the country's total electricity demand, 80m powering 1 million homes.

The production of power over time is measured in megawatt-hours (MWh) or kilowatt-hours (kWh of energy. Production of power at the rate of IMW for 1 hour equals IMWH of energy, 1kW = 1,000 W 1 MW = 1,000,000 W average household use 10,000 kW/year 1 GW = 1,000,000,000 W There are strict guidelines on wind turbines and noise emissions to ensure the protection of residential amenity. In Ontario, wind turbines have to be a minimum of 550 metres from the nearest house, with 2 kilometres now being considered. How noisy are wind turbines? at 90dB, sustained exposure may result in hearing loss 30dB 40dB 50dB* 70dB 80dB 90dB 100dB 110dB whisper at 6' fridge turbine vacuum average traffic lawnmower subway rock concert *Measuring wind turbine noise varies widely and is criticized by industry opponents. Wind by the Numbers Installed Capacity (MW) The Canadian Wind Energy Association (CanWEA) believes that wind energy can satisfy 20% of Canada's electricity demand by 2025. 2011: 6,201 6,000 Canada will see an average of 1,500 MW of new wind projects 5,000 commissioned on an annual basis over the 0o0 2010: 4008 next four years. 2009: 3,319 0.81 3,000 0.81 9.20 2008: 2,369 2,000 2007: 1,846 YT 9.20 NT NU 2006: 1,460 1,000 (BC 2005: 684 2004: 444 54.70 1,116.60 7,013.00 389.70 SK 258.50 54.70 781.70 242.00 NL AB 197.60 MB 1,349.20 2,043.20 4,479.20 197.60 2.822.30 ON QC -PE 163.60 173.60 NB Current installed capacity 6,201.11 MW 2015 installed capacity 16,401.81 MW 'NS 294.00 324.00 * all numbers listed in MW 309.00 318.70 Pro or Anti-Wind? The country of Denmark gets 20% of power from wind ANTI - a number the government would like to see increase to 50% by 2020. Their wind turbine industry is the World's largest with 38% of the market - employing 20,000 people. There are 171 anti-wind groups in Denmark Learn more about wind turbines @ CBC.CA/DOCZONE © 2012 CBC Radio-Canada.
