WORKS CITED
Nacelle
Oldest known windmill
Developed by Persians
Used to grind grain
Europe
Used to grind grain
Had 4 blades on horizontal axis
Drained fields
Netherlands
Water irrigation in France
French settlers bring wind turbines to Canada
By the late 1700s in Europe
Wind power is used to drain lands, grind grain, mill timber and process commodities such as spices and tobacco.

Windmills pump water for farms and ranches on the Western frontier.
The blades on early farm windmills are made from simple wooden slats.
Charles Brush builds the first wind turbine to generate electricity.
17 meters tall and had 144 cedar rotor blades
Darrieus a french inventor
Made vertical-axis rotor with slender curved blades
German Inventor
Advanced horizontal axis turbine
Fiberglass and plastic blades with variable pitch made it more efficient
World’s first offshore wind farm begins operating off the coast of Denmark.
India adds 300 megawatts of wind power
The United States adds 1,700 megawatts of wind power
End of 2002, United States’ wind generating capacity is concentrated in California and Texas.

The U.S. and Europe dominated the wind power industry
Germany lead the world in terms of wind energy; employing 35,000 people and supplying 3.5% of the country’s electricity

2004 Global wind energy generating capacity exceeds 39,000 megawatts.
2008 The Wind Turbine development expanded to Michigan and other high wind current states.


Installed wind capacity more than doubled
In five U.S. states, 10% or more of electricity generation came from wind power

The Solution
Studies show that wind turbines aren't a problem
San Gorgonio Pass study
National Wind Coordinating Committee (NWCC) study comparison
Wisconsin study
BIRD DEATH PER YEAR
Size obstacles
Economic obstacles
Off shore turbines
New ideas
Why Windmills?

Alternate energy source
Fossil fuels can deplete
Why here, why there?

Windmill placement is crucial!
