Transcript of Wind Energy

ABOUT 1 TO 2 PERCENT OF SOLAR ENERGY IS A CONVERTED INTO WIND ENERGY
WHEN THE SUN HEATS THE EARTH'S SURFACE UNEVENLY THE HOT AIR RISES AND COOL AIR DESCENDS
THE MORE THE PRESSURE CHANGES OVER A GIVEN DISTANCE THE MORE SWIFT THE WIND WILL BE. THIS IS CALLED
PRESSURE GRADIENT FORCE
IF THERE IS A LARGE PRESSURE DIFFERENCE BETWEEN TWO POINTS THAT ARE DISTANT THE WIND SPEED WILL BE LOWER THAN IF THEY WERE NEAR
It is also form of solar energy
Wind energy is one of the fastest growing energy resources on the planet
Wind energy is a renewable energy resource and fossil fuel
AS AIR ASCENDS THE PRESSURE LOWERS AND SURROUNDING AIR TAKES ITS PLACE MOVING IN A CIRCULAR MOTION RESULTING IN WIND
What is wind energy?
Advantages-
Clean resource, doesn't pollute
It is a inexpensive energy resource
It is a renewable resource
It is wildly distributed
Doesn't effect wildlife habitats
Disadvantages-
wind blades kill up to 20,000 to 37,000 birds a year
Wind is also the largest form of
green

energy
very noise polluting
lubrication oils for the turbines are expensive
wind is not always the same pace therefore the production of wind is not always consistent
WHERE DOES WIND
COME FROM?
Environmental Impact
Clean source of energy
Doesn't consume fuel
Kills or injures thousands of birds each year
Causes natural disasters such as cyclones, hurricanes, ect.
The turbines make bad noise pollution
The turbines don't require water for cooling
Economics
Not expensive to start up
It is getting cheaper and cheaper
Not practical everywhere
Less expensive then most resources
Have to pay for repairs of windmills
How is wind used?
Ancient people used wind to get sailboats to move before 5,000 b.c. It was and still is today used to grind grain and pump water. The most significant thing we use it for today is to generate electricity. Wind farms generate the electricity using windmills. There are two types of windmills, the horizontal axis and the vertical axis. The horizontal axis stands as tall as a 20 story building with three blades that span 200 ft across. It is also the most commonly used windmill. The vertical axis has two blades that go from top to bottom and it is 100 ft. tall and 50 ft. wide. This type of windmill is not used often.
Where can wind be used?






















































Wind is used mainly on wind farms. Wind farms can only be in rural or agricultural areas. Many places use wind energy, but only if the government supports it. It is used most extensively in Denmark, Germany, Spain, India and in the U.S. The top five states in the U.S that use wind energy are Texas, Iowa, California, Minnesota and Washington. You may not know this but wind is also used on water! Off-shore is more expensive than on land, but it is steadier and stronger and better quality.

Wind energy is an inexhaustible energy resource
It is a plentiful energy resource that is cheap and it prices keep decreasing
Renewable energy resource
Very reliable
Inexhaustible energy
The most sustainable way to generate electricity
Cannot be controlled
Clean resource
Green energy is energy that is friendly to the environment. All renewable energy resources are green.
Wind is simply just air in motion
