Wind Energy
Alex, Isabel, Jack, Kameron
Advantages• environmental friendly, because no
greenhouse gases are given off• wind is free
• work manually when the wind blows• wind is a renewable source• doesn’t pollute at all
• cheap
Disadvantages
• the wind is not constant all of the time• noisy
• disfigure the land they are being built on• not pleasing to look at
• can interfere with TV signals
When wind blows onto the blades, they spin in circles creating energy to power homes and
other sources.
Wind turbines are placed in open lands, ideally by water where more wind is
generated.
US Creation (%)
WindOther Sources
Only 3 percent of all energy created
in the United States is wind energy.
As more research is being found,
the percentage of wind energy in
the United States is going up. The
United States is already first
worldwide in wind energy
consumption, which shows that
most countries aren’t utilizing wind
energy as a resource.

United StatesWorldwide Consumption
of Wind Energy (%)
This graph shows the percentage of
energy created worldwide. The
United States leads in wind
production, consuming 31% of all
wind energy. China is second in
wind consumption with 23% of all
wind energy. The rest of the world
has not yet developed the
technology for wind, which shows a
lower percentage for wind creation
in the graph.

Usage of Wind Energy in the United States
ResidentialCommercialIndustrialTransportationRejected Energy
This graph shows the usage of
wind energy in the United
States. Most of this energy is
going towards transportation
and the least is going towards
commercial use. Even though
wind energy is being used
much more effectively than in
the past, only about 75% of
wind energy is being used
while more than a quarter of
this energy is still being
wasted.
Wind Energy vs. Fossil FuelsWind Energy Fossil Fuels
• Does not emit carbon • Releases a lot of carbon
• Wind is an unlimited resource • Fossil fuel will eventually run out
• Wind is free • Fossil fuel is expensive
• Does not release particles • Releases particles into the air, which could cause cancer
• Wind energy does not pollute water sources
• Can pollute groundwater, rivers, lakes, and drinking sources
• Does not cause climate change • Could contribute to climate change
• Wind is more efficient and uses less energy to do more work
• Fossil fuels use more energy to do less work
How Wind is used in the United States
• Wind is used to turn wind turbines which generates electricity.
• The electricity created by the wind turbines is used to power homes and businesses.
• Wind is 3.3% of all generated electrical energy.
U.S. Wind Generation
This graph shows how much energy(Mega watthours) was produced each year since 1997.
Wind Generating Capacity for U.S.
This map shows how much energy can be produced by each state.
Questions• 2 examples of wind energy on public land are
windmills near farms and wind mills near the coast.
• 3 Uses of wind energy outside the U.S, 1 in the UK they use windmills along coast, Denmark makes a quarter of its energy from windmills, The UK has the largest wind farm.
