How much power do these generate?

[Andrew Ferguson]

Having seen that they want to make a wind turbine farm locally to me (out to sea) I'm trying to get the facts together.  I have heard differing stories that they are not generating as much as the government says they are, and others that say we should convert more to wave and wind power.  I'm even thinking about getting one at my house (see my other thread).

What are the outputs and savings for these please?

I'm not sure any renewable energy source is generating quite the amount of power that people imagined they would generate when the ideas first took root. But I do think that it is a decent idea to get one in your home if you have the space, because it would mean, at the very least, that you would be able to start to generate some of your own power and therefore save on energy bills.

Which company have you chosen to look at installing your turbine for you? They should be able to provide you with some statistics so that you could decide whether it would be worth it for you or not. It is a big decision to make, especially as there is a chance that it could affect the value of your home. You should check with some estate agents about whether they think it would have an impact or not, and if the answer is yes then of course you may want to think again about it.

The largest turbines can generate 8MW at maximum capacity, but most will be in the 3MW-5MW range. as for overall capacity, that depends on the size of each turbine, and the number in each farm.

Home turbines are usually around the 1KW mark, and it mostly depends on how much electricity costs for you, alongside government subsidies.

As a general rule of thumb, most turbines will generate 5-7% of the cost of the turbine per year, so you can expect to see a ROI within 13-20 years, though often government subsidies make the ROI even greater.

about 25-30% of capacity. So if it is rated as 4MW it will generate on average 1MWh per hour.

That's actually quite a good return on investment, and has made me seriously consider getting one installed.

Every wind turbine has a range of wind speeds, typically around 30 to 55 mph, in which it will produce at its rated, or maximum, capacity. At slower wind speeds, the production falls off dramatically. If the wind speed decreases by half, power production decreases by a factor of eight.
