WIND

WHAT IS IT?

• Wind is a renewable resource.
• It is the natural movement of air in a certain direction.

HOW DOES IT WORK?

• Wind blows because of the rotation of the earth.
• It also is also made by the cold and warm air mixing.
• The pressure (gravity) also causes wind to occur.

HISTORY OF WIND

• It would propel boats along water sources.
• It helped the Persians pump water.
• Propelled wind mills.

WHERE IS IT FOUND?

• Wherever there is temperature change and gravity.
• Everywhere on earth

HOW WAS IT RECOVERED?

• People created wind mills and wind turbines to preserve energy by making energy out of the wind captured.

HOW IS IT STORED AFTER RECOVERY?

• In batteries after it is captured by the wind turbines.
• Hydrogen fuel cells
• Compressed air storage

HOW IS IT USED?

• It allows people to go boating without a motor.
• It spins wind turbines making energy.
• It can also be used for sense of direction.

IS IT EFFICIENT?

• Yes, because it is natural and it will never go away for good.
• It also doesn't have a negative impact on the environment and it does not cost much to convert to energy.

CAPITAL COSTS

• Wind itself is free so it has no fuel cost.
• When it is converted to energy it costs $1940 per kW
• 75% of the total cost for wind energy is spent on equipment and setup. The rest is maintenance and storage.

SETUP COSTS

• A wind turbine costs about $48,000 to install.
• The equipment itself costs about $40,000.

ONGOING OPERATING COSTS

• 75% of the total cost for wind energy is spent on equipment and setup. The rest is for maintenance and storage of the energy.

ADVANTAGES OF USING WIND

• It is natural
• It is cheap
• It is renewable
• It is reliable and does not pollute the earth

DISADVANTAGES OF USING WIND

• Trees can be cut down for space for the wind turbines
• They can be noisy
• The turbines are very visable
• Birds can collide into a rotor blade and die.

ECONOMIC IMPACT

• It is cheap compared to other sources of energy.
• It allows you to save money in the long run because the majority of costs come in the beginning and after that they are cheap.

ENVIRONMENTAL IMPACT

• Compared to other sources of energy it has little impact on the enviroment
• There is concerns about the death of birds crashing into to rotor blades.
• There is also a concern of trees and fields being destroyed for room.

IS THERE A HIGH CONSUMER COST

• No, the cost of wind energy is cheap compared to the other sources of energy.
• The wind turbines do not cost much after they have been purchased and setup.

INTERESTING FACTS

• Wind Mills have been used since 2000 B.C.
• Wind power is the fastest growing energy source in the world.
• One wind turbine can power 500 homes
• Wind power uses virtually no water.

FUTURE OF WIND ENERGY

• Wind energy will continue to grow.
• With technological advancements and the limitless supply of wind the development will be unstoppable and keep getting better.
