 * Resources:**

Wind turbines, like aircraft propeller blades, turn in the moving air and power an**electric generator** that supplies an electric current. Simply stated, a wind turbine is the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity.found on http://windeis.anl.gov/guide/basics/index.cfm found by Brent chivington

More info from paragraph above
 * Wind energy is produced by windmills. Windmills are essentially a type of generator that converts kinetic energy (motion energy) into electrical energy. Wind energy comes from the motion of the air. According to the Department of Energy, air over land heats up faster than air over [|water] . When the warm air over land rises, the cooler air over water rushes in to replace it. This creates wind.
 * The blades on a windmill catch the wind and the windmill turns. The windmill has an internal shaft that turns inside a generator to produce electricity. The generator produces electricity by spinning a magnet inside a coil of wires. When the magnet turns, it forces electrons through the wires and thus electricity is generated.
 * The electricity that is generated travels out through wires. A small wind turbine that produces less than 100 kilowatts of electricity can be used to power a [|single] home. Or a large group of wind turbines together make up a "wind farm" that can send electricity out into a power grid and provide electricity for a whole city or even multiple cities.

Wind power is the world's fastest growing electricity generation technology. Wind is a renewable resource because it is inexhaustible. It is a result of the sun shining unevenly on the earth. The corresponding daily and seasonal changes in temperature consistently generate wind, producing a fuel source that can never be depleted. more wind about how it's produced

[|Wind Power by noelia]

<span style="background-color: #ffffff; display: block; font-family: inherit; font-size: 12px; text-decoration: inherit;">**Wind Power Starts with the Sun**

<span style="background-color: #ffffff; display: block; font-family: inherit; font-size: 12px; text-decoration: inherit;">Wind power is actually a form of solar power, because wind is caused by heat from the sun. Solar radiation heats every part of the Earth’s surface, but not evenly or at the same speed. Different surfaces—sand, water, stone and various types of soil—absorb, retain, reflect and release heat at different rates, and the Earth generally gets warmer during daylight hours and cooler at night. <span style="background-color: #ffffff; display: block; font-family: inherit; font-size: 12px; text-decoration: inherit;">As a result, the air above the Earth’s surface also warms and cools at different rates. Hot air rises, reducing the atmospheric pressure near the Earth’s surface, which draws in cooler air to replace it. That movement of air is what we call wind. <span style="background-color: #ffffff; display: block; font-family: inherit; font-size: 12px; text-decoration: inherit;">**Wind Power is Versatile**

<span style="background-color: #ffffff; display: block; font-family: inherit; font-size: 12px; text-decoration: inherit;">When air moves, causing wind, it has kinetic energy—the energy created whenever mass is in motion. With the right technology, the wind’s kinetic energy can be captured and converted to other forms of energy such as electricity or mechanical power. That’s wind power. <span style="background-color: #ffffff; display: block; font-family: inherit; font-size: 12px; text-decoration: inherit;">Just as the earliest windmills in Persia, China and Europe used wind power to pump water or grind grain, today’s utility-connected wind turbines and multi-turbine wind farms use wind power to generate clean, renewable energy to power homes and businesses.

<span style="background-color: #ffffff; display: block; font-family: inherit; font-size: 12px; text-decoration: inherit;">**Wind Power is Clean and Renewable**

<span style="background-color: #ffffff; display: block; font-family: inherit; font-size: 12px; text-decoration: inherit;">Wind power should be considered an important component of any long-term energy strategy, because wind power generation uses a natural and virtually inexhaustible source of power—the wind—to produce electricity. That is a stark contrast to traditional power plants that rely on fossil fuels. <span style="background-color: #ffffff; display: block; font-family: inherit; font-size: 12px; text-decoration: inherit;">And wind power generation is clean; it doesn’t cause air, soil or water. That’s an difference between wind power and some other renewable energy sources, such as nuclear power, which produces a vast amount of hard-to-manage waste.

<span style="background-color: #ffffff; display: block; font-family: inherit; font-size: 12px; text-decoration: inherit;">**Wind Power Sometimes Conflicts with Other Priorities**

<span style="background-color: #ffffff; display: block; font-family: inherit; font-size: 12px; text-decoration: inherit;">One obstacle to increasing worldwide use of wind power is that wind farms must be located on large tracts of land or along coastlines to capture the greatest wind movement. <span style="background-color: #ffffff; display: block; font-family: inherit; font-size: 12px; text-decoration: inherit;">Devoting those areas to wind power generation sometimes conflicts with other priorities, such as agriculture, urban development, or waterfront views from expensive homes in prime locations.

<span style="background-color: #ffffff; display: block; font-family: inherit; font-size: 12px; text-decoration: inherit;">**The Future Growth of Wind Power**

<span style="background-color: #ffffff; display: block; font-family: inherit; font-size: 12px; text-decoration: inherit;">As the need for clean, renewable energy increases, and the world more urgently seeks alternatives to finite supplies of oil, coal and natural gas, priorities will change. <span style="background-color: #ffffff; display: block; font-family: inherit; font-size: 12px; text-decoration: inherit;">And as the cost of wind power continues to decline, due to technology improvements and better generation techniques, wind power will become increasingly feasible as a major source of electricity and mechanical power.

<span style="background-color: #ffffff; font-family: verdana,arial,sans-serif;">Modern wind turbines fall into two basic groups; the **horizontal-axis** variety, like the traditional farm windmills used for pumping water, and the **vertical-axis** design, like the eggbeater-style Darrieus model, named after its French inventor. Most large modern wind turbines are horizontal-axis turbines.

I found [|this article]talking about the environmental effects of wind turbines. This article focuses mainly on the slight noise that is produced by the wind turbines which has become a near non existent problem recently with newer designs and better insulation. It also mentions that wind farms are not very aesthetically pleasing. The main issue that this article poses is the large fatality rate associated with wind energy and birds and bats. Even though this is a problem I found another [|scholarly paper] abstract that talks about how small of a number the estimated 7000 is when compared to other types of energy. Found by Gabriel Dunn

By Audrey Gibbs* I found this page about the pros and cons of which i will give at the end. wind energy is a very green source of energy but it also costs some green as well because it is fairly new technology. The thing is this energy is renewable and we should never run out of it like oil and other sources. We also have enough space on earth for wind turbines. The government will pay people to put turbines on their property. :The con to this is they tend to be somewhat noisy and can get very annoying. Wind is unpredictable the availability of wind energy is ** fluctuating **. Therefore, wind energy is in most cases not suitable for providing a base load of energy. This is why wind turbines should be used together with other renewables or even non-renewables to meet the power demand. http://energyinformative.org/wind-energy-pros-and-cons/

Katie Frazee: file://localhost/Users/katiefrazee/Desktop/hurricane-4.jpg

A large [|wind farm] may consist of several hundred individual [|wind turbines] which are connected to the [|electric power transmission] network. Offshore wind power can harness the better wind speeds that are available offshore compared to on land, so offshore wind power’s contribution in terms of electricity supplied is higher. [|[10]] Small onshore wind facilities are used to provide electricity to isolated locations and utility companies increasingly [|buy back surplus electricity] produced by small domestic wind turbines. Although a variable source of power, the [|intermittency] of wind seldom creates problems when using wind power to supply up to 20% of total electricity demand, but as the proportion rises, increased costs, a need to use storage such as [|pumped-storage hydroelectricity], upgrade the grid, or a lowered ability to supplant conventional production may occur.

 * Katie Frazee (Advantages) **

**2.** Once the wind turbine is built the energy it produces does not cause green house gases or other pollutants. **3.** Although wind turbines can be very tall each takes up only a small plot of land. This means that the land below can still be used. This is especially the case in agricultural areas as farming can still continue. **5.** Remote areas that are not connected to the electricity power grid can use wind turbines to produce their own supply. **6.** Wind turbines have a role to play in both the developed and third world.
 * 1. ** The wind is free and with modern technology it can be captured efficiently.
 * 4. ** Many people find wind farms an interesting feature of the landscape.
