Transcript of wind energy !

Energy produced
using wind for our energy instead of having to use our nonrenewable sources will help our environment alot.
we would not have toxins or any other harmful things forced into the air.
may cause bird decline.

tradeoffs
how it works
Why we need it !!
Wind Energy
Fun Facts about Turbines!!
A single turbine can power up to 500 homes.
Modern wind turbines produce 15 times more electricity than the typical turbine of the 1990's.
In 2014, the U.S. was home to 46,000 operating wind turbines
Windmills were first developed in China and Persia.

objections?
the windmills may take up to much space .
killing of birds.
would be overbearing and dominate the landscape
Noise pollution
insufficient production
The main reason for using wind energy
is so that we use less fossil fuels.
Wind does not let off any carbon emissions that fossil fuels does.
NO AIR POLLUTION !!
Wind turbines consist of three things, a nacelle, rotor, and a tower.
The nacelle compartment is connected to the rotor hub by a shaft and contains the generator, and systems that maximize energy.
The rotor, usually consists of three wing-shaped blades connected to a central hub.
The tower provides the height necessary to access the wind, and create the electricity.
When wind turbines are added to a utility system, they increase the overall probability that the system will be able to meet its requirements.
While wind is an irregular resource, other generating systems also have outages for repair.
The exact amount of energy that a wind project provides depends on average wind speeds in the area its in.
Wind is low-cost emerging renewable energy resource.
The purchase and installation of very small turbines generally cost $4,000 to $9,000, and larger turbines can cost $350,000.
it will cost consumers around

Wind turbines vary in size.
Generating electricity is measured in watts.
The output of a wind turbine depends on the turbine's size and the wind's speed through the rotor. Wind turbines being manufactured now have power ratings ranging from 250 watts to 1.65 megawatts.

energy efficient?
Cost
reliable?
wind energy is a renewable energy making it more reliable than others.
turbines sensor to predict the output of wind and solar with high accuracy, making it easier for operators to integrate where the wind is best coming from to get the most energy.

to be able to use wind energy you would hve to build turbines to collect the energy.
find places with the best wind maybe causing them to cut down trees.
Changes

need energy?
wind energy collects it own energy which means that it would not need to have other energy sources to help it
replace
would replace all fossil fuels due to it not needing any and it being a renewable source.
Wind power is currently supplying 48 billion kilowatt-hours of electricity annually in the U.S. which power the equivalent of over 4.5 million homes. Wind power is an important part of electric utility power. it supplies a good amount of energy and due to it being renewable it should be able to greatly increase in usage in the next 10 years.
