Wind energy
Wind energy is used to generate electricity instead of coal
Wind energy is less harmful to the environment than coal and other fossil fuels
Wind energy is received by the coast in wind turbines to be used for many things like heat,electricity,and many other places as well
Wind energy
Wind energy helps save the use of fossil fuels Wind energy uses renewable energy instead of
nonrenewable energy Wind energy does not hurt the ozone layer like
the use of fossil fuels More and more people are using wind energy
Wind Turbines Vs.
Coal Factories
“Wind Turbines” are better for the planet because, coal factories burn coal witch causes smoke and makes our earth sicker than it already is.
Wind turbines don't use any kind of smoke in which makes them better for our earth.
How is “Wind Energy” better for the earth???
Wind Turbines And The Environment!!Wind energy system operations do not generate air or water emissions and do not produce hazardous waste. Nor do they deplete natural resources such as coal, oil, or gas, or cause environmental damage through resource extraction and transportation, or require significant amounts of water during operation. Wind's pollution-free electricity can help reduce the environmental damage caused by power generation in the U.S. and worldwide.In 1997, U.S. power plants emitted 70% of the sulfur dioxide, 34% of carbon dioxide, 33% of nitrogen oxides, 28% of particulate matter and 23% of toxic heavy metals released into our nation's environment, mostly the air. These figures are currently increasing in spite of efforts to roll back air pollution through the federal Clean Air Act.
The Cost of Wind Energy
The less expensive construction costs are,the lower the cost of energy.
The higher the wind speed, the lower the cost of energy.
The larger the wind farm, all other factors being equal, the lower the cost of energy.
The Cost of Wind Energy
The cost of wind has dropped over the last 20 years.
In the early 1980's,when the first turbines were installed, wind generated electricity cost as much as 30 cents per kilowatt-hour.
Now, state-of-the-art wind power can generate electricity for less than 5 cents per kilowatt-hour.
Types of Wind Machines
There are two types of wind machines
Turbines: used today based on the direction of the rotating shaft.
Horizontal-axis: is the main wind machine used today. It's as tall as 20-story building with 3 blades
that span 200 feet across.
How wind energy works Wind energy is another
form of solar power ,because wind energy is heat from the sun.
For explain: a fan if is not on and your window is open the wind can spin can spin the blade and create wind energy.
t
Where does Wind Energy work best?
Wind energy works best in flat areas.
Near open plains or fields. The western part of the United
States will work good.
Can wind energy work best anywhere
Would this be a suitable place for wind energy?
Wind energy does not work best anywhere
Wind energy cannot work best anywhere because the blades are about 200 hundred feet long and as tall as a 20 story building.
How wind energy works
Wind energy is just another form of solar energy that come
How wind energy works
Wind energy is cause by Wind energy is cause by the uneven heat of the the uneven heat of the earth surface by the sun earth surface by the sun i.e. Less at the pi.e. Less at the poles oles and and more at the equator. more at the equator.
This heating is more This heating is more rapid upon dry land when rapid upon dry land when compared to the sea. compared to the sea. The air get expanded and The air get expanded and reaches high altitudes reaches high altitudes while the cool air comes while the cool air comes down which blow as wind.down which blow as wind.
