Your Questions About Wind Turbine Generators Australia

Mark asks…

Tidal power and coal?

Tidal power is still more expensive then coal ($0.04 /kWh versus $0.018 /kWh) and is only available to those with access to the ocean. However, the research is very promising with advances coming routinely, such as Vortex induction to underwater turbines. The question is, should the government subsidize tidal energy production research on the same level as wind, solar, and geothermal? And if so, what government state or federal, because tidal power is very geographically sensitive, but so is solar and wind?

admin answers:

I think that tidal (and wave) power is a great option as a renewable energy resource. I live in Australia so we have lots of oceans and an absence of baseload high quality viable renewable energy sources (solar chimney technology is getting there but still could not be considered to be a baseload source due to variation in sunlight intensities). Tidal has the benefit of being able to be predicted well in advance (we have tide charts after all) and in equatorial regions tides can be huge. Wind was at the same stage as tidal 30 years ago and is now a viable source. From a microgeneration perspective small communities throughout Asia and the Pacific would benefit from the ability to install a small tidal turbine (rated to say 500kW) that would reduce the need to use diesel generators which cost far more than $0.04/ kWh. I definitely think that governments need to invest strongly on tidal energy.

John asks…

Do Many Australians use wind mills for electrical generation?

You must import a lot of materials to use. It would expensive to import coal for power generation. I have read some articles that you have windmills to generate electrical power for lighting, radios. Here in the USA we had small wind generators for pumping water, generating some electrical power for lighting. This was in the 1900’s.The power companies were stringing wires through the country and giving the farmers good incentives to use their power sources. Then they keep jacking up the rates. We are starting generating power on a larger scale of wind power.These are of course owned by the power companies. It seems to be pretty slow developing. I read about one farmer in La-Cross, wis. Who 20 years ago bought a giant windmill for $20,000,He ordered a new one ,more efficient. He also was selling electrical power. The electrical companies do not make it easy to allow people to generate power. From the history I See Australia, The Dutch Netherlands should be leaders in the production of wind Electrical energy. Why are You Not?
Wow 1 I did not realize Australia was almost as big as the Usa. That Is Great ! Aussi’s are great people ! A few I have met in Vietnamn ! I was on a restrickted base,did not get out much. I Hope to see more of Ausralia in the News,in energy saving devices. your country knows how to work and survive. Keep it up!

admin answers:

Some farms in remote areas have wind mills for power generation and there are also some commercially run wind farms. I copied the stuff below from a alternative energy page.

“South Australia’s ninth wind farm just opened on the Barunga Ranges near Snowtown. Its 47 turbines, installed by Trust Power of New Zealand, (who already operate that countries largest wind farm at Tararua), are said to have the capacity to deliver over 98MW of electricity. The company reckon this output should provide sufficient power for around 70,000 Australian households.

Not only was this project completed ahead of schedule, but it allows the state of South Australia to claim that they now produce almost 60% of Australia’s wind power. Additionally it means that South Australia is poised to meet Prime Minister Kevin Rudd’s target for all states to produce 20% of their energy from renewable sources by 2020.”

Your Questions About Wind Generators For Sale

Carol asks…

what is 1 KW in terms of electricity?

i am trying to buy a wind power generator and it says it produces 1kw electricity.
can u explain it to me in lay man terms.
for example it can supply electricity for ___ no of fans, ___ no of tube lites etc

admin answers:

1KW will run quite a few low energy lamps, plus a computer, TV or HiFi etc.

It would not run an electric kettle or or anything else much in the way of heating appliances.

The BIG problem you will have is that a ‘1KW’ wind generator will probably only average 100W on a good day.

Look very carefully at the ratings and figures of the device before you spend any money.
Some of the generators on sale only give the headline rating if mounted on a tall mast on top of a hill & with a gale force wind…

They put windfarms in open spaces & on tall masts for good reason. The airflow near buildings & obstructions is generally so turbulent it’s a waste of time trying to use a small wind generator in a town.

Do some research and find reports from other people who have bought the one you are looking at first, otherwise you are likely to pay out more than you can save in electricity over the lifetime of the machine.

Daniel asks…

Is there any steryotypical misconceptions about Amish people?

admin answers:

There are a multitude of misconceptions about the Amish. Here are just a few:

The Amish don’t use any modern technology – FALSE. The Amish are selective about the technology they use. They tend to reject technology that they feel would have a significant negative impact on their lifestyle, but are accepting of technology they do not see a problem with. Also, what technology is accepted and what is rejected depends on the Amish affiliation and each individual church community.

The Amish feel electricity is evil – FALSE. This has to be the most ridiculous of all the misconceptions. Most Amish (but not all) do not want electricity supplied by utility companies in their homes. They do, however, use some electrical devices where they can generate the power themselves through the use of gasoline generators or battery (which they charge using solar or wind power). They also do not want natural gas lines into their homes from utility companies, but readily use bottled gas (propane).

The Amish produce all of their own food and clothing – FALSE. I live in an area with a very large Amish population. I see Amish people in supermarkets and department stores all the time. The local Walmarts have tie ups for the horse and carriages.

The Amish do not use modern medicine or doctors – FALSE. The Amish have no aversion to modern medical practices or medicines at all. They go to doctors when they need to. They are hospitalized when it is required. Some Amish women still use midwives for birthing, but many use doctors and give birth in hospitals, especially for difficult pregnancies.

The Amish live communally without any outside contact – FALSE. Amish families live in their own private homes on their own private land. They own private businesses or work outside of the homes and manage their own finances. They keep bank accounts and take out loans for homes or business. They participate in many community activities with the general public, especially those that involve charity work.

The Amish don’t pay taxes – FALSE. The Amish pay all income, property, and sales taxes. They can claim an exemption from Social Security with-holdings under certain circumstances (are self employed or work for an Amish owned business), but if they do then they can never collect any SSI benefits either, and are therefore not a burden to the SSI system.

Your Questions About Wind Turbines For Home Use

Paul asks…

Is it worth my while investing in natural energy for my home?

I was thinking about investing in some Solar Panels and a small Wind Turbine to power my home.
I live alone and do not consume lots of electricity.

From what I hear I am looking at waiting at least 10 years before I see them pay for themselves.
Is this true? Are they really more trouble than they are worth?

Because if the cost-benefit ratio is too unbalanced, I might as well just stick to nuclear power.

admin answers:

Hey X, what you’ve been reading is basically correct, you are looking at probably 10 + years for your financial payback. If that is what you are after, probably better to spend a few dollars making your living space a bit more efficient, which will cut down on your current electric bill, and put the rest in long term bonds. You’ll get your money back faster with the investment.

We live in a home that is completely powered by the wind and sun. It still has the utility company connected, which I now use as my storage battery for excess power, and then I can draw on them if I need extra down the road. There is a small fee for that too. The original reason we got involved is because at the time, our power was always going out at inconvenient times, and later for environmental reasons. If, as you say, the cost benefit ratio is too unbalanced, you might as well stick to nuclear, then I’m guessing environmental benefits are not of interest to you. Lots of people grow tomatoes in their garden even though it’s easier and cheaper to buy them at the store, or the farmers market if you want fresh. For them it’s therapuetic to make something of their own, and provide at least a sustainable patch of green grass in a world of commercial vegetable fields. The only difference between them and us is we just grow electrons in our garden, even though it is probalby cheaper to buy them commercially, from the nuclear plant, or someplace else. There is also the fact that our home has not been without power for even a minute the last 13 years now, but it’s hard to put a price tag on something like that.

If you really think you might want to get involved a little without having to bet the farm, try starting small like we did 13 years ago. A couple of golf cart batteries, one 70 or so watt panel and a few miscellaneous parts and we were lighting our kitchen and bath and running a few small electronics, like a radio, cell phone charger and so on. And within months when the next power outage came, those items continued to function, free of charge or gasoline. Home Power Magazine liked our small starter idea so much years ago they ran a small article on it. If you subscribe, you can use their online archive search engine and look for an article called, “Small System First.” If you’re handy with stuff around the house, it might be a good project for you. Check out the magazine and some other sources below. Good luck X, and take care, Rudydoo

Laura asks…

questions to include in a questionnaire for home wind turbine?

i am doing this for my design technology and i am creating a wind turbine a small one for home use and i have to create a questionnaire, nd i have already ran out of questions to include.

admin answers:

Will any one in your household object to noise and vibration from even a small wind turbine? If so, the turbine needs to be on a separate tower, not attached to the house.
Are there any nearby tall trees? If so, the cost of a tower taller than the trees may be 80% the total cost. Trees reduce the average wind speed. Worse trees cause variation in the wind speed from one second to the next. This increases the wear on moving parts in your turbine. Electrical watts out is proportional to the 4 th power of the wind speed = 6 mile per hour winds produce very little electricity.
Did you check your location for frequent high wind speed? If not you may be very disappointed in the watthours you get. Neil

How to Face India’s Future Energy Crisis?

India is located at a perfect location and has the most perfect weather than Why are we not taking advantage of it?
India is surrounded by oceans, meaning coastlines, where its most windy, so why don’t we have Wind Turbines to produce Electricity?
India is one of the countries that experiences long summers, and most sunny days, then why don’t we have Solar Panels to produce electricity?
These technologies are much better than burning coals to produce electricity, coal burning releases carbon dioxide which is a major cause global warming.
Where as Wind and Solar Energy Technology are clearn energy souces. We have these technology available to us, then Why not use it at a larger scale?

admin answers:

The energy policy of India is characterized by tradeoffs between four major drivers:

Rapidly growing economy, with a need for dependable and reliable supply of electricity, gas, and petroleum products;
Increasing household incomes, with a need for affordable and adequate supply of electricity, and clean cooking fuels;
Limited domestic reserves of fossil fuels, and the need to import a vast fraction of the gas, crude oil, and petroleum product requirements, and recently the need to import coal as well; and
Indoor, urban and regional environmental impacts, necessitating the need for the adoption of cleaner fuels and cleaner technologies.
These trade-offs are often difficult to achieve. For example, the supply of adequate, yet affordable electricity generated and used cleanly is a continuing challenge because expansion of supply, and adoption of cleaner technologies, especially renewable energy, often means that this electricity is too expensive for many Indians, particularly in rural areas.

In recent years, these challenges have led to a major set of continuing reforms and restructuring.

1 Energy conservation
2 Electricity industry
3 Alterative bio-diesel sources
4 Wind power showcase
5 Oil
6 Nuclear power
7 Solar Energy
8 Policy framework

Energy conservation
Energy conservation has emerged as a major policy objective, and the Energy Conservation Act 2001, was passed by the Indian Parliament in September 2001. This Act requires large energy consumers to adhere to energy consumption norms; new buildings to follow the Energy Conservation Building Code; and appliances to meet energy performance standards and to display energy consumption labels. The Act also created the Bureau of Energy Efficiency to implement the provisions of the Act.

Electricity industry
The electricity industry has been restructured by the Electricity Act 2003, which unbundles the vertically integrated electricity supply utilities in each state of India into a transmission utility, and a number of generating and distribution utilities. Electricity Regulatory Commissions in each state set tariffs for electricity sales. The Act also enables open access on the transmission system, allowing any consumer (with a load of greater than 1 MW) to buy electricity from any generator. Significantly, it also requires each Regulatory Commission to specify the minimum percentage of electricity that each distribution utility must source from renewable energy sources.

Alterative bio-diesel sources
The President of India, Dr. Abdul Kalam, is one of the strong advocaters of Jatropha cultivation for production of bio-diesel.[1] In his recent speech, the President said that out of the 60 million hectares (600,000 km²) of waste land that is available in India over 30 million hectares (300,000 km²) are suitable for Jatropha cultivation. Once this plant is grown the plant has a useful lifespan of several decades. During it life Jatropha requires very little water when compared to other cash crops. For plan for supplying incentives to encourage the use of Jatropha has been implemented.

Wind power showcase
The once-impoverished village of Muppandal benefited from the building of the nearby Muppandal wind farm, a renewable energy source, which supplies the villagers with electricity for work.[2][3] The village had been selected as the showcase for India’s $2 billion clean energy program which provides foreign companies with tax breaks for establishing fields of wind turbines in the area. Now huge power-producing windmills tower over the palm trees. The village has attracted wind energy producing companies creating thousands of new jobs, dramatically raising the incomes of villagers.[4] The suitability of Muppandal as a site for wind farms stems from its geographical location as it has access to the seasonal monsoon winds.[2]

Oil
Because of political instability in the Middle East and increasing domestic demand for energy, India is keen on decreasing its dependency on OPEC to meet its oil demand, and increasing its energy security. Several Indian oil companies, primarily lead by ONGC and Reliance Industries, have started a massive hunt for oil in several regions in India including Rajasthan, Krishna-Godavari river basin[5] and north-eastern Himalayas. The proposed Iran-Pakistan-India pipeline is a part of India’s plan to meet its increasing energy demand.

Nuclear power
While India is self-sufficient in thorium, possessing 24% of the world’s known and economically available thorium,[6] it possesses a meager 1% of the similarly calculated global uranium reserves.[7] The United States-India Peaceful Atomic Energy Cooperation Act is expected to greatly help India in obtaining a steady supply of sufficient nuclear energy in the longer run.

Solar Energy
India’s theoretical solar potential is about 5000 TW·h per year (i.e. 600 GW), far more than its current total consumption. Currently solar power is prohibitive due to high initial costs of deployment. However India’s long-term solar potential could be unparalleled in the world because it has the ideal combination of both high solar insolation and a big potential consumer base density. [8][9] A major factor influencing a regions energy intensity is the cost of energy consumed for temperature control. Since cooling load requirements, unlike heating, are roughly in phase with the sun’s intensity, cooling from intense solar radiation could make perfect energy-economic sense in the subcontinent, whenever the required technology becomes competitively cheaper.

Policy framework
A long-term energy policy perspective is provided by the Integrated Energy Policy Report 2006 which provides policy guidance on energy-sector growth.

Lisa asks…

Got any suggestions, wacky or otherwise, for topping up the battery of electric cars?

You may have heard recently in the news about the governments plan to boost electric car sales by offering subsidies of upto £5K for electric or plug-in cars ( http://news.bbc.co.uk/1/hi/business/8001254.stm ). One of the problems with electric cars is how to top-up the battery without excessive down-time (ie periods where you can’t drive the car). Have you any suggestions, wacky or otherwise, for how to do this?

My own suggestion is to divert some airflow through tubes that run the length of the car (maybe even avoiding the passenger compartment!), with miniature wind-turbines inside that help recharge the battery.
>There wouldn’t be near enough power >generated from that small amount of wind to >make any noticeable difference. Seriously.

Ever tried trying to open the door of your car when it’s traveling at 30mph or more? You might discover that the ‘wind‘ is not that small!
>It would require MORE energy to move the car >and you will get less energy from the turbines >due to irreversibility’s.

Irreversibility’s of what?
>You can’t get something for nothing. The car’s motor is what is making the wind you feel. If you put a turbine out the window or in a tube or whatever, you would make less energy than you use to make the wind to turn it with (friction, less than 100% efficiency…).

I agree you can’t get something for nothing. The idea of the tubes would be to take some airflow that would have otherwise been acting to slow the car (through friction of airflow, or drag), and to instead partially convert it to electricity (via the miniature wind-turbines). I wouldn’t stick the wind-turbines out the window!
>How about putting a dynamo into the passenger side window winder. Whilst driving along the passenger can repeatedly wind the window up and down to generate electricity to help top up the batteries. This would also dramatically cut down on friends who wanted to ponce a lift somewhere as well. heeeeheeeheee.

Good idea, but with some minor problems:
Extra drag whilst the window is in the open position.
Your passenger may develop RSI.
Your passenger may develop bigger arm muscles to thump you with!
>can it run on feces?
If you could bear the stench!

admin answers:

Regenrative braking is the most effective way of topping up the battery by recapturing waste energy and already used on most electric cars and hybrids

Solar pannels could contribute something, but would increase the weight of the vehicle, and probably drag too.

A generator trailer is a well tried solution = instant hybrid for long journies, but without carrying the weight & complexity for normal travel. Http://www.evalbum.com/2312

the first question to ask is given that an electic car can travel 200 miles before recharging and then recharged in 10 minutes http://www.phoenixmotorcars.com is this really “excessive downtime”. The driver should take a 10minute break too after 200 miles.

Carol asks…

how much of the earth do we need to cover with solar cells to meet current energy demands?

If the world’s current power demand is 14TWH and the Sun produces 120000TW/Y or around 14TW/h. how much area of the earth would we need to cover in solar panels to reach current energy demands?

admin answers:

Hey Brian, interesting question, and one that gets to the heart of many renewable energy myths today. Your explanation might have a couple apples vs oranges. The sun produces much more power than 120,000 terawatts, or terawatts per year, but I’m not sure if TW/Y represents either of those. Total electrical energy use on our globe is about 15 terawatts continuously, or 132,000 TW hours each year. Since solar panels are about 12 to 14 % efficient today, it would take an area of 192 square miles to produce that much power. Problem is, you would need it to work 24/7, and most places on our globe are dark at night. Accomodating for night time, and twilight hours in the morning and evening when the panels would be operating below peak power, the number jumps to about 890 square miles, or about 39,000,000 acres. That sounds huge, but consider that Rhode Island takes up over 1500 square miles, and is one of the smallest states in the US, really that scenario is feasible. The fact is we are never going to do that. The cost, the enourmous demand for silicone, wiring, grids, and so on make it totally impractical. There is also the fact that Rhode Island is pretty cloudy.

Now enter the Germans, they have a fantastic plan to mine solar power from the Sahara Desert. It doesn’t involve solar panels, instead they are going to use solar thermal collectors that will heat oil to several hundred degrees, which will be circulated back into huge insulated tanks, then the hot oil will be used to boil water into steam ,which will turn a steam turbine. This idea has several advantages. First, since we can use both the light of the sun, and its resultant heat as opposed to a silicone panel, which uses only the incoming photons, the efficiency jumps to about 60%. Second, since oil does not boil until around 550 degrees, we can use the stored hot oil well into the night until it cools substantially. Now we have access to solar power at night. And the concentrators and oil(which gets continuously recycled each day) cost much less per unit power than any panel in production today. Since the efficiency is much higher, they will only need 30 to 40 square miles to power all of Europe. If you want to check it out, google, “North African Solar Project,” and read some of the resulting websites. If the system works as well as they plan, it will run most of Western Europe, and then we will probably have one in our desert southwest a few years later. This concentrator will not offset any wildlife, beyond a few scorpions and rattlesnakes living in the far out areas of the desert, and since they will be using sea water to boil into steam, the byproduct of the electrical production will be fresh water. That fresh water will be used for irrigation to farm small quantities of sunlight intensive farm stock in what is now a completely dry desert. Adding small amounts of plant life to the northwest corner of the desert where none exists now will not alter the climate, but does offer another opportunity for carbon to be converted to oxygen, reducing the CO2 content of the atmosphere slightly. There will be jobs there, installation, technicians, maintenance and operations, and as long as the sun shines in the desert, we won’t run out of fuel.

We’ve been powering our home for 11 years now on wind and solar power. I’ve learned many things during that time. One item is that there are two things in large supply in solar power, the sun, and missinformation. Lots of people have been posting interesting “facts” here about solar and wind power, having never laid a hand on a panel or wind turbine. Wind turbines do not kill as many birds each year as living room windows do, powering homes with solar panels does not require massive amounts of space, silicone panels do not need massive amounts of toxic chemicals to manufacture them, and people do not get cancer from spinning wind turbines. These are just a few of my favorites, there are many more. If you want to learn more about this technology, check out some sources below. Take care Brian, Rudydoo

Your Questions About Wind Turbine Generators For Home Use

Donald asks…

How is electricity produced for the electric companies ?

Where do they get theyre power to power all the homes and businesses ?
&&
How do they keep getting power ?
Do they ever run out ?

admin answers:

Electricity supply is produced by large Power Generation Stations and sold to the distribution Companies who then distribute and sell it to the users.
The Power Generation Stations, consist of various types of Industrial Plants:
1…Burning of Fossil Fuels…Oil, Coal or Gas which are used to produce vast amounts of high pressure, high temperature (superheated) steam. This steam is used to drive (rotate at high speed), huge Steam Turbines which are connected to large Power Generators that produce the Electricity into a ‘Power Grid’ network which feed the electrical companies who then supply the Industrial and domestic users.

2..Combustion Gas Turbines use the Energy of an Expanding mixture of Superheated Air and Combustion Gases to drive high speed turbines that drive Power Generators….and so on..as above.

3..Use of Rivers or Lakes behind dams. The huge volumes of flowing water from these sources provides massive amounts of Kinetic Energy which is utilised to drive large Water Turbines which, in turn drive Power Generators….the rest is as above.

4..Wind Turbines are used to do exactly he same thing…A large ‘Propeller’ type windmill drives a generator…etc.

5..Nuclear Power plants use the tremendous heat of atomic fission to produce vast amounts of high pressure, high temperature (superheated) steam. This steam is used to drive (rotate at high speed), huge Steam Turbines…etc.

In each case, the Kinetic Energy of the power source is converted to Mechanical Energy (Turbine) and then into Electrical Energy (Generator)..

Joseph asks…

How is energy from a wind turbine transferred to the national grid ?

Isn’t the current DC ?

admin answers:

Answer #3 was sort of right. You are correct, because of the variances in speed, those generators tend to be DC machines. From the wind turbine the “juice” is fed to inverters that can be phase controlled as well. The DC, after conversion to true sine wave AC, and phase locked to the grid system, and it’s voltage adjusted for the feed point where it will be added in, is switched into the grid system at that point. Best use, unless you have millions to invest in wind turbines and the hardware to go with it, is to use the power at your home, yourself.

Your Questions About Wind Generators Cost

Lizzie asks…

Can I build a wood fired domestic electricity generator power station in the garden?

I have unlimited supply of wood. The excess heat to be used to heat the house and swimming pool. Excess electicity to be sold to the grid.
Would the capital cost be prohibitive? The running costs are not a problem. Is there a commercial turbine on the market.
My capacity to burn is determined by the cost of one man and a J C B to load a commercial incinerator.
I would exect a large input of D I Y in this project.

I know that planning permission may be required

admin answers:

Its difficult to give a complete answer here.
Firstly we have to say that however you build your project it will be extremely difficult to make it green.
The reason is that the amount of Carbon you release will be enormous compared to the amount released by a commercial power station producing the same amount of electricity.
So from a commercial point of view have you looked at the price you will get from the buyer??
I assume you are in the uk.
If you look into selling to “the grid” you might find that the price will be very low indeed.
The amount you could get would depend on when you generated, ie were you only on at peak times,
If you produce electricity only now and again which is the most likely case I expect the amount you would get paid would not cover the cost of the diesel to power your loader and the man’s wages.
First check what you could get paid for the power you produce and when it is produced.

(it would most likely be very very little) It is not legitimate to look at what you are charged for electricity.

So your best plan I believe is to generate enough electricity for yourself and forget about export.

The problem with this normally is that you have to have your power station going 24/7.
Thats a lot of work.
What you could do is build a mini hydro scheme.
This is done very little but is very green.
The draw back is that you need two enomous ponds of water separated in height by about 10 feet (min).
You have a water wheel which runs 24/7 producing your electricity.
This is powered by water running from your top pond to the bottom one.

Now once per day you need to pump up the water from the bottom pond to the top. You can do this with very simple steam lift system.
Anyone with basic engineering skills could build this system.
If you could make your ponds big enough you can run your wood/steam powered lift system less often.

BTW solar is the best way to heat your pool. Very inexpensive effective systems now available. DIY systems cannot compete here.

Solar or wind could also be used to pump water to the top pool. This method means you dispense with batteries which are only 70% efficient and not Green. They are expensive and need to be replaced every 5 years making small projects using batteries. .
Micro-Hydro is the way to go. You will not find much on the web. You are welcome to mail me if you want to know more.

I know you will be disappointed in not being able to sell your power but the cost of the equipment compared to the payback time would make it a bad plan.
(like I say it would also be very un eco freindly)

Good luck with whatever you try.

Susan asks…

How much would it cost to change the world to renewable energy?

Say one man had unlimited money. Say he wants to power the entire world off of renewable resources (solar, tidal, wind, wave). How much would it cost him, in an instant, to pay for a world’s worth of renewable generators?

admin answers:

As of 2007, the cost of solar power was 38 cents per kwh while the costs of coal power was 0.6 cents per kwh. It isn’t a matter of what one man could afford but what if everyone’s power bill went up to 63 times what they are now.
