Wind power Defined Wind power Defined BrieflyBriefly The use of wind generators to create The use of wind generators to create
electricity for either private or public electricity for either private or public energy consumptionenergy consumption
It is a completely clean, environmentally It is a completely clean, environmentally safe, renewable, energy source safe, renewable, energy source
First One Must Know Wind First One Must Know Wind Wind is created when hot air rises, Wind is created when hot air rises,
decreasing the atmospheric pressure decreasing the atmospheric pressure near the Earth’s surface, which pulls in near the Earth’s surface, which pulls in cooler air to replace it. cooler air to replace it.
That movement of air is called wind and That movement of air is called wind and it occurs because the solar radiation it occurs because the solar radiation from the sun heats the Earth’s from the sun heats the Earth’s atmosphere at different amounts and atmosphere at different amounts and speeds speeds
How Does Energy Fit InHow Does Energy Fit In The hot and cold movement of air The hot and cold movement of air
produces kinetic energy—the energy produces kinetic energy—the energy created whenever mass is in motioncreated whenever mass is in motion
Using the right technology the kinetic Using the right technology the kinetic energy in wind can be converted into energy in wind can be converted into other forms of energy such as electricity other forms of energy such as electricity
What Technology is UsedWhat Technology is Used The main and most important device The main and most important device
that alternative energy people use is the that alternative energy people use is the Wind TurbineWind Turbine
It consists of a large propeller blade, a It consists of a large propeller blade, a generator/gearbox, and a tower holding generator/gearbox, and a tower holding them upthem up
Define a Wind TurbineDefine a Wind Turbine A machine used to harness energy by A machine used to harness energy by
having a large vane wheel rotated by having a large vane wheel rotated by the wind to generate electricity.the wind to generate electricity.
The ProcessThe Process Incoming wind blows the propeller Incoming wind blows the propeller
round, which turns the generator to round, which turns the generator to produce electricityproduce electricity
AdvantagesAdvantages Wind is free of cost and fuel is not Wind is free of cost and fuel is not
required in wind farmsrequired in wind farms The land below can still be used for The land below can still be used for
farming farming Good way to supply energy to windy Good way to supply energy to windy

green house gases into the environmentgreen house gases into the environment Using new technology wind can be Using new technology wind can be
harnessed more efficiently harnessed more efficiently Wind farms are also able to be used as Wind farms are also able to be used as
tourist attractions tourist attractions
Tourist Attraction Wind farm in Beer
Creek, PA People can come
there to see the farm
Disadvantages Wind turbines are noisy like a family car
going 70 mph Wind is not constant. There can be days
without wind The amount of wind available limits the
locations where farms can be built
More Disadvantages People protest that wind farm land
should not be messed with, yet should be natural
Some people find wind farms to be unnecessarily big and unattractive
Wind power currently needs to be more efficient
They’re Big Wind
generators are colossal so they can get hit by lightning pretty easily
Geography of Wind Farms
Locations Areas with large wind speeds (electricity
generated by wind speed cubed) Open farm land at the top of round hills
More Locations They can also be placed in open plains
and in between the gaps of mountains A relatively new area to place wind
turbines and generators are offshore coasts
History Farmers have always been using wind
energy to pump water out of wells Windmills were the basis of wind power
and it has been around for centuries
More History Windmills have been around since 200
BC in China Wind power is the fastest growing
energy source and with power buildings for many years to come
Wind Industries AWEA (American Wind Energy
Association) WWE (Western Wind Energy) You are not ready for the windmill
