Wind Energy Provides Europe With 8% Of Its Electricity In 2014

The capacity factor tells you how much electricity you’re getting or expect to get out of a given amount of “nameplate” capacity. A kW of solar panels will give different amounts of electricity depending on where they are installed. In SoCal you might get 5.5 average hours of sunshine per day, a CF of 23% but in the NE you might get only 4.2 avg hours, a CF of 17.5%. (Take a look at the map below.) That tells you that you might need to install more panels in the NE and it lets you calculate your $/kWh. If you know the CF of a wind farm you can use that and its total nameplate capacity to determine how much electricity it should produce over a year. Right now an older wind farm is being repowered with new turbines. If we know the CF then we can calculate the amount of electricity that will be produced. 18 MW * 24 * 365 * CF = Annual electricity produced. Absolute power prod...
