I recently saw an article on Yahoo news about a guy that purchased a wind turbine for personal use. He spent around $ 65k. He figured it would take about 8 years to pay for itself.
That might give you an idea on what to expect.

Answer by GABY
I work a lot in west Texas. They have thousands of them. Most of them are about 1.25 MW, and cost about $ 2,000,000-$ 3,000,000 each. That would probably serve about 80-100 houses when producing full power. Of course, you would need another source when the wind is not blowing over 6-7 MPH.
They also pay the land owner about $ 3000/yr lease payments. I do not know what the cost of connecting it to the grid, all the environmental permits, etc. would be.

Pretty costly power, but would be good for the environment.

Answer by j p
GABY’S answer is correct.

I knew of the price of 1.5 million Dollars per wind turbine, but in this price range a tiny more or less is rather insignificant, since those who dream about this could not afford to purchase one in the first place.

GABY please e-mail me the location of the retirement community in Mexico. I have been playing with the thought to retire down there myself, like so many others. It certainly would cost a lot less living there. Thanks in advance, JP.

Hint: convert all your length measurements to meters. Multiply them together to get meters-cubed. Multiply by the density to get kg. Multiply by the temperature change to get kg-oC. Multiply by the specific heat to get kJ.

Remember to always check your units!

if you do it offen then it will save you alot, but doing it like once a week it will be very little

Answer by scoutma53
A dryer is a HUGE user of power, you will save lots. Even just hanging your damp clothes on a clothes horse in your house, they will dry quite quickly. I do not find cold water washes are really effective in removing grease stains. I do not have a dishwasher but I know they go on for about 45 mins and it takes me 5 mins to wash dishes by hand.

Answer by krk
Since it is routine work you will save a lot of power.

Here are some sites which should help in your research and yes costs would vary due to the costs of where the infrastructure was built and how simple it is to get to, to maintain the facilities.

More energy then anyone would know what to do with.

Answer by Me
loads of enrgy

Answer by The Lemur v1.03
Currently I think PV cells capture about 13% max of the light hitting them. One idea has been to put a giant solar panel out in space and then have it shoot a super powerful beam of energy down to a station on earth which would catch it. So then the panels dont have to be here and were not limited to ground space. Its just kind of scary. What if some space rock hit it and knocked it 1 degree off? Suddenly some laser might go slicing through your neighborhood setting everything on fire!

25% of 123 is 30.75 therefore Jake saves $ 30.75 per month.

Answer by golgafrincham
The question is deficient on several levels…but if we take it at face value and assume:
A) Jake’s water heater is electric ; and,
B) 25% of Jake’s electric bill is used by his water heater; and,
C) his solar water heater will create ALL his hot water, then:

$ 123 x 0.25 = $ 30.75 savings per month

If you really want to annoy your teacher, here are some questions to ask:
A) We do not know, do we? He might have a gas water heater. What if he already has solar, or lives near a hot spring? Then his electricity savings would be $ 0
B) But what if he already has a super efficient water heater, or a very inefficient one? Or what if he never takes showers? Or maybe he takes really long showers?
C) Where does Jake live? If he lives in a valley between two tall mountains, a solar water heater might not make enough hot water for his needs.

Quite frankly, since I am a smart alec, I would answer this question: “since Jake uses natural gas to heat his water, he will not see any savings at all on his electric bill after he installs his solar hot water heater.” I think you could argue with your instructor about whether you should get marked wrong on that one. Make sure your parents know BEFORE you do this, if you so choose!

Solar panel costs P220. per watt. A solar panel rated 200 watts costs P44.000.00. You will still need other accessories like battery, inverter and battery charger controller.

Answer by Jurandr
It really depends on the model of the turbine. Around where I live, the turbines can survive about 30 miles an hour, but after that they are spinning so swiftly it’s dangerous, and automagically shut down.

Answer by bak123
they have brakes similar to automobiles that apply pressure to the rotor which regulates the speed, so they can handle just about any wind, the brakes help keep a constant rpm

Check any of the Green substitute energy providers and they will reveal their cost and source as they try and get you to contract with them for power.

Answer by dale
you can save a tiny but not a lot you probably will not even notice a difference in your bill

Answer by Kim b
you will save a tiny but you will save even more by adding a hot water wrap also known as a hot water blanket I would also recommend adding a time to you your hot water heater this combined with the blanket can save you up to 10 dollars a week. Set the timer so it is on two or three hours in the morning and again for two or three hours in the evening this will not only save on you electric bill but will also extend the life of you hot water heater. The initial cost could be a tiny high depending on where you live and who you get to install them but within two months it would pay for it self
