How can you become a wind farmer?
You can become a wind farmer by getting all wind farm equipment like gusts and wind blows and learning all about wind farming.
How will wind turbines help your environment in the future?
it will mean that there will be more fossil fuels to burn in the future and then the normal electricity to use x
What do wind farms and solar farms look like?
well wind farms have have wind minds and solar farm have solar panels and if i am
not right you can ask your sicince teaher if i am not right
Why are hydroelectric power and wind powercalled clean energy?
Both wind and hydro-electric power, along with solar, geo-thermal, tidal are called clean energies because they do not create, in themselves, any waste products requiring disposal. Oil, gas, coal and nuclear energies all create waste products in one form or other which need disposal.
Who owns the emu downs wind farm?
What energy source does not require waste disposal?
Energy produced by wind turbines does not require any waste disposal. 9.8 percent of the energy consumed in the state of Michigan is produced from wind turbines.
Is it worth having wind turbines?
The simple answer is 'yes' of course they are -- but the reason many people don't buy and install large or small scale wind turbines is because too many reports base their decision on whether they are 'cost-effective' rather than whether or not they save 'energy'.
This slightly detracts from the idea that we as a society are all supposed to be 'saving energy' and turns it into whether or not you personally are 'saving money'.
If you genuinely want to live a more sustainable life then you should either buy or build your own wind turbine to reduce your dependence on fossil fuels -- and help reduce the need (or excuse) for the government to build new coal-fired power stations.
I am well aware that there a financial constraints for all areas of our lives -- including kids, holidays and mortgages -- but if you have made a conscious effort to reduce your energy consumption then a wind turbine will of course take ages to 'earn it's cost back' -- as you are using less energy!
Wind turbines are more 'cost effective' if you use a lot of electricity on washing, drying, console games and heating and plan to continue to do so -- as you will see the savings rack up a lot faster than those who are more energy-conscious.
So in my book, if you want to have an eco-friendly house -- the cost shouldn't be the main issue.
So, How Do Wind Turbines Work?
It all depends on something we have a lot of -- and it's free and carbon, nitrogen and methane free!
Wind turbines -- as their name suggests -- harness the power of the wind (which is free and ever coming) which in turn, rotate specially shaped wind turbine blades. This rotation transfers the energy from the blowing wind down into a turbine which changes it into another energy -- electricity.
Depending on the size of the turbine and the strength and continued blowing of the wind you will produce more or less energy. I have seen small wind turbines on canal boats and residential wind turbines on garage roofs and sides of houses, larger ones in stables and in gardens, and of course ginormous wind turbines in large scale establishments or in wind farms.
Now, you can use that energy as it is created and store 'spare' energy to use later in special batteries or, you can let excess electricity be pumped back into the National Electricity Grid -- and get paid for it!
Does the electric company have to connect to your property if you have a wind generator?
If your generator makes enough power to run your equipment then no they don't have to connect to your property unless you ask them to,
How much does one wind turbine produce electricity?
Wind turbines come as small as 100 watt units and as large as 5 Megawatt units.
A typical system will have a normal output of about 8% of what it is rated for.
How safe for the environment is wind energy?
WIND ENERGY AND THE ENVIRONMENT
Wind energy is an excellent sustainable energy source, but no energy production is completely without impact on the environment. After all, even the slightest change in our surroundings has some effect, sometimes positive, sometimes negative. However, energy from the wind has very little impact on the environment for the following reasons:
WIND IS CLEANER
Many kinds of energy production produce harmful substances. For example, burning coal for energy yields sulfur dioxide, which causes acid rain. Wind energy helps offset traditional electricity generation's negative effects on the environment. Wind farms do not release any pollutants such as carbon dioxide (a greenhouse gas that contributes to climate change), sulfur dioxide (which causes acid rain) and nitrogen dioxide (which causes smog). By supplying power from a clean, renewable resource, wind energy helps reduce pollution, keeping our environment healthy for future generations.
WIND IS SAFE
Wind farms have many advantages for both people and animals. Wind farms are safe for animals on the ground, and since wind farms take up a very small percentage of land on which they are sited, most of the land can remain in use for crops or grazing. There are regions in the world in which wind farms can have an adverse impact on birds. However, many studies have been done in the United States and Europe on birds and wind turbines. Most of these studies have shown that birds tend to change their flight path in order to fly safely past the wind turbines. Nevertheless, at Horizon Wind Energy we always take into account bird migratory routes or flywayswhen siting our wind farms to prevent avian difficulties. We also take into account nesting grounds and other bird-related issues.

How much is it to run wind power?
Actually, it is so profitable and in demand, that you can lease your land for windmill companies, one windmill for every quarter acre, and still use the land for things, like cattle raising.
How many types of wind power are there?
There are really only two types of wind turbines. Alternating current and direct current.
They range in size from 400 watt units up to 5 megawatt units. They typically will produce about 8% of the rated power.
A 400 watt unit will be able to produce 400watt/hours if the wind is blowing exactly 28 mph. If the wind gusts to 31 mph the systems will stop producing power. At 14 mph they will produce 10% of the rated power. All things considered, these systems are still not able to produce usable power for the world. Hopefully, they will get better.
How will wind be used in 2138?
energy in the form of electricity is generate using windmills for this propose wind farms have been established.
How do people feel about having a wind farm?
Wind farms provide clean renewable energy. So people who live a long distance from a wind farm probably feel good about using this source of energy. However, wind farms create noise and this is a serious problem for people living close to the farm. Two other problems are visual pollution and impact on wildlife- primarily the killing of birds.

How do Wind turbines capture wind?
Wind turbines have blades that rotate when the wind blows, converting the kinetic energy of the wind into mechanical energy. This mechanical energy is then converted into electricity by a generator inside the turbine. The turbine's orientation and design help to maximize the capture of wind energy.
How many wind turbines are needed to power Britain?
The population at the moment in Great Britain is: 61,838,154 according to Google Public Data stats.
The approximate "peak power" consumption would therefore be: 309.191 GWh based on 5 kWh per person. This takes into account commercial/industrial & residential use per person. Many factor a home at around 3kWh divided by the average people per home but they forget to factor in the infrastructure to support the community such as dry cleaning, food stores, gas stations, etc...
Divide the Total GWh Peak of 309 by 1.5 MWh of the average large Turbines (propellers) and we come up with: 206,127 units to provide 309,191GWh for GB usage in the middle of the day with everything turned on and full production.
Factor in an approximate cost of $2 million per unit we arrive at a project cost of: $618,381,540,000. That $618.3 Billion.
Now factor in cost of Power Transmission which some quotes are as low as $1.5 million per mile and up to $10 million per mile for a California project. So we'll go with $2 million to be kind. If we created this project off shore, with 206,000 units, yikes, we might break the project into say... 50 projects of of 4,150 units each. Thus if the average offshore distance was 5 miles, we'd have a total of 5 x 50 = 250 miles x $2 million = $500 million for transmission to get to the shore and hopefully tie into a main point in the construction grid.
Add in a 10% contingency factor and we're over $700 Billion for the cost of the project. Using the same calculation factors puts the cost of producing peak power for America with wind at over $7 Trillion with over 1.7 billion units and around 2 billion acres of land.
Other factors: The projection of 1.5 MWh is generated when the wind is at 14 mph. Finding locations on our planet where wind averages 14 mph 24/7 is....? Wind maps show average wind speeds around the world with averages around 3 to 4 mph. The wind belt from the Texas panhandle up through the Dakota's shows around 8 to 9 mph. Thus the true results of these projects is worth pursuing. Projected power of a wind farm vs. reality once constructed and tested over a year or two.
My question would be: Is this the answer or are we being over promised by sales people making a ton of green on green? For example: Shepards Flat Oregon 845 MWh GE Wind Farm - $2 Billion project covering 30 sq miles of pristine land. That $2 billion will create a total of 35 jobs once in operation and kill almost 2,000 birds, including eagles, yearly.
Vestas is working on a new 7MWh unit with a total diameter approaching the length of two football fields. Cost factor still unknown? Impact on birds, downwind effect, other? China is working on a 10MWh unit! They're coming!
I wonder if we put enough of these monsters up might we slow down the rotation of the planet and every would fall off? After all rotation speed is what creates Earth's gravity right?
As you can tell I believe there is still a better solution!
Comments certainly welcome!
How do you make wind on simanimals ds?
If u have enough "happy points" then hold R & L and blow into the microphone.
Wind turbines make noise due to the aerodynamic forces acting on their blades as they rotate. The noise is primarily caused by the turbulence in the air flowing around the blades, as well as mechanical components such as the gearbox and generator. Additionally, the swooshing sound of the blades cutting through the air can also contribute to the overall noise level.
What causes some winds to be strong and some winds to be weak?
The strength of winds is primarily influenced by the pressure difference between two areas. Larger pressure gradients lead to stronger winds. Other factors such as temperature differences, topography, and the Earth's rotation also play a role in determining wind speed.
What are six advantages of wind power?
- It is free, after installation.
- It is renewable, coming back day in, day out, for ever.
- It is carbon neutral, that is, it doesn't contribute to global warming by emitting carbon dioxide.
- It can be used to generate electricity, thus replacing dangerous fossil fuels (coal, oil and natural gas).
- Wind turbines only need a small space, so farming can still carry on underneath them. They can also be placed off-shore.
- The turbines are awesome and majestic, and serve as reminders to everyone that we can and should be cleaning up our world.
Why using wind power to generate electricity is not popular in Hong Kong?
i don't really know for sure but my mum is Asian and she lives in hong kong and she says they have sex alot and you get very sweaty on beds so you need a powerful air con
