electric motor and some fan blades will do it.

How to estimate the energy of a wind turbine?

Question by wwelect2391: How to estimate the energy of a wind turbine?
How to estimate the energy of wind turbine?
how do i estimate the annual energy output of a 5kw wind turbine in an area which has a average wind speed of 7.4m/s at 10m above ground level, and the rated wind speed of the turbine is 10m/s. there is no buildins around to interfear with the wind and the hub of turbine is 12m above ground level. and could you show me the formula for this sum.

Best answer:

Answer by Jay
It's not quite that simple.

Wind turbines have a 'power curve' showing their output at various wind speeds. An 'average' can be based on minor variations (7.2 to 7.6 m/s) or major variations (3 to 12 m/s - OK, that averages to 7.5, but you get the point). Since the energy in wind varies with the cube (third power) of the wind speed, the amount of variation in the average is critical.

There is a calculator here: http://www.windpower.org/en/tour/wres/pow/index.htm, but I highly recommend you review the other information on the site before spending any money!

Best of luck!

So are wind-generators really only 10% efficient as one of the denier troll accounts claimed yesterday?

Question by Andrew Q: So are wind-generators really only 10% efficient as one of the denier troll accounts claimed yesterday?
Yesterday one of the better known semi-retired troll accounts used by a well known denier claimed wind generators are only 10% efficient, is this even remotely true, or just more fantasy.
He cited as his source a green trust, does this also mean deniers have given up on their theory greens are behind a global conspiracy on AGW and deniers now trust them as a source, oh sorry I think I just gagged on the irony.

Answer by vmaldia
well, we in the philippines already have very high electricity prices. then we tried solar and wind power. I dont care about efficiency much since wind and solar use free energy sources. for the average consumer who's poor, we care about the bottom line, which is price

now the problem is, its still more expensive than fossil fuels. Since the renewable power plants could never sell electricity at the same price, the government gives them a subsidy called a "feed in tarriff" which is passed on to consumers. That has cause electricity prices to rise more and now there's a backlash. See links for news reports about the issue

Natural Gas Residential Electrical Generator?

ej — Mon, 14 May 2012 17:42:38 +0000

Question by thesalemcat: Natural Gas Residential Electrical Generator?
I live in Massachusetts, and due to the Cape Wind project our costs per KWh will soon be increasing from a little over 8 cents per KWh to 30 cents or more. Plus National Grid charges a Monthly Delivery Fee of nearly $ 50 whether I use any Electricity at all.

I don't have Air Conditioners, I have nothing but CFL's, and I unplug everything in sight when I'm not using it. My Electrical Bill is still over $ 100 a month.

When it doubles and triples I will not be able to pay my bills.

So I'm thinking a small Natural Gas Electrical Generator might help me. If I could generate my own Electricity for 15 to 20 cents per KWh I could pay my bills and keep my house.

Has anyone done this ?
Ralph B says my statements are not accurate. I guess he's calling Ted Kennedy Jr . a liar.

See:

http://www.bostonherald.com/news/politics/view/20101030cape_wind_dont_be_tricked/srvc=home&position=0

I, on the other hand, don't think a Kennedy would lie to me.
I've never been able to afford Air Conditioning. Fortunately in Massachusetts fans suffice quite well.

I might look into a Gas Powered Refrigerator.

Do they make Heat Pump Refrigerators ? I ask because six months of the year it's as cold as a Refrigerator outside. If they made a Heat Pump Refrigerator that I could keep on the porch I'll bet it would use very little energy.
I do have Gas for heat, water, and for the Clothes Dryer.

If they were Electric I'd so so screwed.

How many wind turbines / farms are there?

Question by Olie122333: How many wind turbines / farms are there?
I need to know many wind turbines / farms there are, preferably in the UK but world-wide would be OK too.

Also, does anybody know how many of these are at sea?

Thanks,

Best answer:

Answer by Earth Man
"A bunch."

Look at the link below, and keep in mind that those are only the ones considered "large" as generating more than 120 megawatts.

I don't think that there are currently any existing offshore, but they are proposed.
