Energy production is in KWh produced in one hour, i.e. how much energy the V112 would produce if the current wind speed was kept steady for one hour. We have chosen to use the unit KWh because this is something that people can relate to. In fact you could just remove the ‘h’ and you would have the actual output of the unit with the current wind.

The CO2 savings is tons pr day and is calculated using the same extrapolation as described above. If the wind blows with the current strength for 24h, then we would save this much CO2. The app does not know how much CO2 is used to produce electricity at your exact location, it is an average. Remember, this is not exact science, it is just to give you all an impression of the scale of capabilities of the V112.

Whether or not our location is good for the unit or not can not be concluded just by looking at current production, not even if you sit for days checking out the production. When Vestas assess potential wind turbine sites we usually demand at least one year of on site data to get an overview of high and low wind seasons. Furthermore we compare this year to 10 years of meteorological data to determine if the measured year was a high, medium or low wind year. If the site is complex, we perform CFD. And so on – we dig quite deep into pre-construction production estimates, because once they are up and running, it is really costly to boost the production if you got your wind resources wrong in the first place.

Hope this answers your questions.

@Frank: Come on, it’s just a fun gimmick showing “what if…” to illustrate how much CO2 could be saved by using a wind turbine.

Since most people live in cities what city (town, etc.) in the world would allow anyone to install one of these in their back yard even if they had enough space??? The blade diameter is 112 meters (336+ feet), the hub height is either 85+ meters or 119 meters and the sound produced ranges from 101 decibels to 106.5 decibels with wind speeds from 7 meters per second to 10 meters per second.

good questions, Doc. i don’t have the app (as you can see in my article above), .. i emailed your questions to Vestas to find out… we’ll see.

The information the app gives about how much electricity a V112 would produce at my location is confusing. It gives the output in kWh and the CO2 savings in tons per day. Does that mean that many kWh per day, per year? And how does it know how much CO2 is used to generate electricity used at my location? In any event it doesn’t look like my current location is too good for this unit.
