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.
