Wind Energy Worksheets:
Environmental Benefits of Wind Energy –
Wind energy is both free and renewable. It works by harvesting the kinetic
energy of the wind without interfering with wind currents or wind cycles.
QUESTIONS: Environmental Benefits of Wind Energy –
Using wind energy also means an annual savings
of billions of gallons of water. While thermal
conventional power plants need water to
produce electricity or to cool power generators,
wind plants do not.
Wind Power and Economic Development –
Farmers and ranchers are able to earn an extra stable
income from leasing the use of their land. This amounts to
over a quarter of a billion dollars in leases annually.
QUESTIONS: Wind Power and Economic Development –
Schools in rural areas also benefit from wind farms, since they expand
local tax bases. As local school budgets derive from tax revenue, this
allows schools to improve their services and facilities.
XXXTITLE 5XXX –
Wind power is considered a renewable source of
energy because the wind cannot be used up,
like coal and oil.
QUESTIONS: Advantages of Wind Energy –
Wind energy also has a lot of potential. Across the whole world, multiple
independent research teams have determined that it is possible to
produce over 400 terawatts of energy from wind alone.
Disadvantages of Wind Energy –
Wind power is generated by harnessing the energy of
the wind through the use of large windmills called
QUESTIONS: Disadvantages of Wind Energy –
Wind power is said to have a low environmental impact, but birds and
bats and other winged wildlife haven't gotten that memo. Studies
estimate that hundreds of thousands of birds are killed every year by
being struck by a rotating wind turbine blade.
Wind Energy and Birds –
About 8% of the electricity produced in the United States is generated
from wind power, and that percentage is growing. Wind energy offers
definite advantages It is renewable.
QUESTIONS: Wind Energy and Birds –
Hundreds of thousands of birds are killed every
year when they collide with spinning turbine
blades and the towers that support them. These
collisions occur most frequently at night, when the
wind turbines are invisible in the darkness.
How Wind Energy Works –
Though wind energy and solar energy are usually
thought of as distinct alternatives to conventional
energy sources, wind energy actually also comes
from the sun.
QUESTIONS: How Wind Energy Works –
Energy from the wind is captured and converted into mechanical power
which is used to generate electricity. The devices used to capture this
wind energy are called wind turbines.
A Modern History of Wind Energy –
Wind power is converted to electricity using large windmills called
turbines. Wind turbines have been in use in the United States since the
QUESTIONS: A Modern History of Wind Energy –
Interest in wind power revived somewhat in the
1970s as a result of the oil crisis, which drove the U.S.
government to invest in renewable alternatives to
Early Uses of Wind Power in the U.S. –
White wind turbines spinning against a rural or
offshore backdrop may strike you as a modern
sight, but humans have actually been using
wind power for thousands of years.
QUESTIONS: Early Uses of Wind Power in the U.S. –
The first windmill in the United States was made by Daniel Halladay in the
mid-nineteenth century. Windmills were very successful at pumping water
on farms and ranches during the westward expansion.
Wind Energy and Agriculture –
Wind energy is an efficient use of space. Since wind turbines can’t be
placed too closely together, wind farms can encompass many acres.
However, unlike solar panels, which make exclusive use of the land they
occupy, wind energy does not disturb natural habitats or human
QUESTIONS: Wind Energy and Agriculture –
Wind power is generated by harnessing the energy of the wind through
the use of large windmills called turbines. Windmills have been used in
agricultural settings for over a hundred years, first to pump water and mill
grain, and late to produce small amounts of electricity before the United
Stated Federal Rural Electrification Administration (REA) brought power
lines and thus a more dependable source of electricity to remote rural
Wind Turbine Sound –
You have probably seen wind turbines in the distance, peacefully spinning
against a backdrop of blue sky. While some people find them
aesthetically pleasing, and even meditative to watch, wind turbines are
not always welcome additions to residential areas because of the noise
QUESTIONS: Wind Turbine Sound –
Human ability to perceive wind turbine sound is
relative to atmospheric conditions (like air flow
patterns and turbulence) as well as whether or
not other man- sound sources are present.
