Transcript of Wind Power Generation

Wind Power Generation in Canada It is clean, green and healthy for the environment. Risks of Wind Turbines
A History of Wind Power
Generation in Canada Small wind turbines common
Provided lighting for farms
The only supply of electricity available
Generated 1 to 3 kilowatts 1930s 1940-1970 Became less common
Lower fossil fuel prices
More accessible in rural areas 1970s Canadian government began to sponsor renewable energy projects
Hydro-Quebec Research developed the "egg-beater" turbine
40 kilowatts
Later developed a 230 kilowatt version
Vertical vs. Horizontal
Axis Wind Turbines Vertical Axis Horizontal Axis Measuring Electrical Output This 100 W light bulb will use 0.1 kW of power when it is turned on. 1980s - Present Horizontal Axis wind turbines became more common
65 kW turbine was designed
Many projects have been and are being developed
Technology increased
1.0 MW - 4.5 MW

Wind Farms in Canada There are 131 wind farms in Canada. Wind Power
the World How do wind turbines work? Wind turns the blades of the wind turbine
Spins the shaft inside a small generator
Small generator produces electricity A typical wind turbine today will generate enough
electricity to meet the power needs of about 500 homes. A wind farm is made up of many wind turbines grouped together.
They produce enough elecricity to power many homes. Nuclear
(15%) Hydroelectric
(59%) Fossil Fuels
(23%) Wind
(2%) Biomass, Solar & Tidal
(1%) Ramea Island, Newfoundland A Renewable Wind Energy Project Small community - 1.89 square km, population 1200
Goal is 100% of energy be produced by wind turbines
Wind-hydrogen-diesel energy system
Wind turbines produce electricity to meet energy needs
Water electrolysis converts excess wind energy into hydrogen
Stored hydrogen later converted into electricity by a 250 kW generator
Diesel generators will supply power when there is not enough available

Melancthon EcoPower Centre Shelbourne, Ontario
Canada's largest wind farm
Open since October 2008
Produces 200 MW of power
133 wind turbines
Generates enough energy to power 70,000 homes The watt (W) measures the rate of energy conversion. 1 kilowatt (kW) = 1,000 W
1 Megawatt (MW) = 1,000,000 W Watts vs. Watt Hours A 100 W light bulb uses 100 watt-hours (0.1 kilowatt-hours) per hour. Generating Power Economic Influence Future of Wind Energy CHINA Became the world's leader in wind generation this year
Over 40,000 MW installed GERMANY UNITED STATES Second largest producer
40,000 MW
Horse Hollow Wind Energy Centre (Texas) Horse Hollow Wind Energy Centre, Texas Leader in Europe
Installed over 27,000 MW http://www.solacity.com/Economics.htm Health Risks Wind Turbine Syndrome
Energy companies deny the side effects
Does not affect everyone
2km separation is recomended

Sleep Problems Headaches Dizziness Nausea Exhaustion Depression Ringing Ears Problems Concentrating and Learning Heart Disease Environmental Risks Kill many birds and bats
6 months almost 2000 birds and bats killed
Deaths from 86 turbines outside of Kingston
Large threat to endangered species
Nature Canada is concerned Landscape Risks People concerned that wind turbines ruin scenary
Construction and foundation may disrupt water flow to wells
Risk of fire Economic Advantages
and Disadvantages No Fuel Permanently available everywhere
Price for fuel is $0.00
No fluctuating prices of fuel
No fossil fuel transportation costs
Economies are less affected by high fuel costs

Lower Long Term Costs Expensive to install: $1.5 - 3 million
More are developed, lower costs
Regular maintenance and inspection
Free fuel
Life span around 25 years
Employment Short and long term jobs
30% more jobs than a coal plant
66% more jobs than a nuclear plant
Employment opportunities include meteorologists, engineers, assembly workers, lawyers etc.
Demands members of the skilled and unskilled workforce
Jobs can help rural economies

No Emissions No air pollutants
Does not contribute to climate change
Fast deployment Ontario Ontario Clean Air Alliance Organization that represents Ontarians
Worked with Ontario government to phase out coal
Coal will be phased out by December 31, 2013
Goal to have 100% of electricity from renewable sources by 2030
Future Plans 124 wind energy projects are waiting for approval
Wind farms are being researched and developed
Ontario Power Authority seeking new electicity sources
Wind farm on Lake Ontario Canada World Canadian Wind Energy Association Toronto Hydro is considering wind farm on Lake Ontario. Investigating possibility of wind farm
Anemometer measures wind speed and direction
2 years, starting June 2010
2-4 km offshore, 25 km in length
Benefits 200 MW potential production
Short and long term jobs
Expands Ontario's hydro base
Environmental stewardship

http://spectrum.ieee.org/energy/fossil-fuels/ontario-quits-coal Unreliable Source Wind speeds vary
Times when production of electricity is 0
Wind is not dependable - 80% of time useful
Always be demand; supply changes
Difficult to store excess supply Production Costs Very expensive
Does not make economic sense to spend money in some areas
Electricity costs vary with wind speeds Interference Can interfere with radar
Interfere with television and radio transmission http://www.solacity.com/economics.htm Canadian organization representing the wind industry community
Promotes development
Vision is 20% wind production in Canada by 2025

Canadian Wind Ontario is the leader in Canada - 1/3
Canada's wind growth rate is 30%
Federal government failed to renew ecoENERGY for Renewable Power
Encourages provinces to invest in wind energy
DENMARK Pioneer for wind energy in the world
20% of electricity is from wind
Highest percentage in the world
Home to the world's top turbine manufacturing company
Global Wind Energy Council Global Wind Global emissions have to peak and decline by 2020
Crucial to reverse climate change
Working to increase offshore generation Promotes wind power
Helps countries develop clean energy systems through wind
Meets and plans future goals and developments
Advanced countries help others
