Wind Power

Air/wind can turn a fan or windmill that is connected to a generator in the same way that water is converted to steam in order to turn a turbine. Air, and more specifically wind, is used to power windmills, that cause a turbine to turn, and generate electricity.

It depends on the efficiency of the appliance. If an electric motor has an efficiency of 0.7, then for every 1000 megajoules, 30 megajoules will be wasted as useless heat or sound or other useless energy form.

The amount of energy produced by wind power has several different factors, such as the amount and strength of the wind. However, some studies show that a 1.8 MW wind turbine can produce over 4,700,000 kWh of energy per year if located at a reasonable site.

If your house has 220vac each leg should have at least 110vac so if you use an electric dryer you would have 110 vac to each leg to run the dryer for outlets and switches it would be the same 110vac volts alternating current to operate electrial devices and to turn the lights on and off.

Heat energy from the Sun causes the variety of weather patterns responsible for creating winds, including "prevailing" winds which are used for locating and powering wind generator "farms."

It is significant to ask this question as the two main types of wind turbines are horizontal and vertical, and these designs use the wind in slightly different ways regarding the wind energy harnessing process.

Horizontal wind turbines are the more common design, and use angled propeller type blades to create friction when facing the wind, resulting in the spinning motion.

The vertical axis design uses the wind to spin on a centre point on the ground, resulting in the whole construction spinning round.

The process of electricity production is significantly similar in both designs. The construction only makes a difference in the position and design of the blades which are used to create friction with the wind.

A large mass of air moving over the landscape represents a considerable amount of energy. By building devices that will spin when the wind blows, it is possible to harness some of that energy. Most modern wind turbines are several hundred feet high, with propellers that have 3 blades, each one about 150 long.

Wind energy potential refers to the amount of energy that can be generated from harnessing wind power in a specific location. Factors that determine wind energy potential include wind speed, consistency, and direction. Areas with high wind energy potential are ideal for the development of wind farms to generate electricity efficiently.

Nuclear energy was first demonstrated by the Chicago Pile 1 in 1942, under Fermi, but this experiment did not produce any useful power. Power producing reactors were built in the US and UK in the mid '50s, and other countries have followed. Since then the principles of using heat generated by fission of U235 (mainly) to drive the normal type of steam turbines and produce electricity have stayed the same. Development has been largely to make plants more efficient and improve safety.

A fuel possesses chemical energy, which is released when the fuel undergoes a chemical reaction such as combustion. This chemical energy is then often converted into thermal energy or mechanical energy to perform work.

1. The wind is free. Fossil fuels cost money.

   Once the initial costs of building wind farms and attaching them to the grid are paid usually within a couple of years, there are fairly minor maintenance costs for the 20 to 25 year lifespan of the wind farm (at which point it is usually replaced with bigger, modern wind turbines). Fossil fuel generation, by comparison, depend on a steady supply of coal or natural gas, which has prices which vary substantially in the short term, but are steadily trending higher on a longer time frame. In many places, wind energy is in the range of 5-6 cents USD per kilowatt hour, on par with or cheaper than direct costs of coal energy, and much cheaper when approximately 18 cents of negative impacts from coal are added in.

2. Wind energy provides carbon-free energy. Fossil fuel energy contributes massive amounts of carbon to the atmosphere.

   Wind energy has a net CO2 balance which is every positive. There are CO2 production costs associated with mining, refining, manufacturing, transport and installation, but these are outweighed by the massive amounts of carbon-free electricity generated over the lifespan of the wind turbine. Fossil fuels, by comparison, release greater than their weight in CO2 when they are burned; burn a megaton of coal, get two megatons of CO2.

3. Wind energy does not emit particulate pollution which kills people. Fossil fuel generation emits particulate pollution which kills people and harms the environment.

   Wind energy does not emit particulate pollution except for minimal amounts in construction. Fossil fuels, on the other hand, are basically burnt with resulting smoke and ash. Smoke and ash get into the atmosphere even with expensive scrubbing. One estimate indicated that coal kills 13,000 people in the US annually alone, and other has over 100,000 direct coal deaths in mining and transport in the 20th century.

4. Wind energy does not pollute water and kill fish. Fossil fuels pollute water and kill fish.

   Wind energy is a net positive for ground water, and has no impact on rivers, lakes or oceans, except providing ore fish habitat when they are installed offshore. Fossil fuels frequently enter ground water, lakes, rivers and oceans directly in spills, or indirectly through air pollution. Acid rain is directly caused by coal generation.

5. Wind turbines make good tourist attractions. No one pays to see fossil fuel generation plants.

   Many places including Japan, Atlantic City and Palm Springs, Nevada have a steady influx of tourists drawn in part by their wind turbines. The same can't be said for coal plants or natural gas generation plants. Rather, the obvious can be stated: people who live near them pay to get away to places with cleaner air.

Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity.

Wind turbines are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more above ground, they can take advantage of faster and less turbulent wind.

Wind turbines can be used to produce electricity for a single home or building, or they can be connected to an electricity grid (shown here) for more widespread electricity distribution.

Wind is predominantly collected and generated using wind turbines. These turbines have blades that rotate when the wind blows, driving a generator to produce electricity. The kinetic energy in the wind is converted into mechanical power, which is then transformed into electrical energy.

Yes, there are wind turbines located near Chicago in the state of Illinois. These turbines are typically found in rural areas outside the city where there is more open space and wind exposure, such as in wind farms.

Wind turbines are used worldwide in countries with suitable wind resources, such as the United States, China, Germany, India, and Denmark. They are commonly found in regions with steady winds, such as coastal areas, plains, and mountain passes. Wind farms are also increasingly being developed offshore to harness stronger and more consistent wind currents.

As most if not all governments are run by big business, wind energy would be a disadvantage to the mining industry, and any industry which depends upon fossel fuels. Government would loose most of its income which is supplies by big business. Taxes would therefor go up to help fill the governments coffers. Like most inventions that would affect big business they would be bought out and the project shelved.

Wind farms are considered as being good.

They provide energy with no pollution.

Downsides are no wind, no power.

The windmills are also quite costly to make and maintain.

In the 80's it was considered that a windmill would never be able to produce energy enough to cover the cost of its production.

This has changed, possibly due to higher cost of electricity.

Windmills are today considered a strong viable source of renewable energy.

One negative aspect of utilizing wind turbines on peak mountains is the potential negative impact on local wildlife and habitats. Installation and operation of wind turbines can disrupt migratory patterns, habitats, and nesting grounds of birds and other species that call the mountains home.

Wind turbines have been used since the late 19th century for generating electricity. The first modern wind turbine, built for electricity production, was constructed in 1888. However, it wasn't until the 1970s that wind turbines started to become more widely used for renewable energy generation.

Wind power has been used for thousands of years, dating back to ancient civilizations that used windmills for grinding grain and pumping water. Modern wind power, in the form of large-scale wind turbines for electricity generation, has been around since the late 19th century.
