Apparent wind in knots and degrees. Note that a number of additional factors come into play when converting the measurements from the masthead anemometer into the true wind if a high degree of accuracy is required, including the following: In the presence of a current, the true wind is considered to be that measured on the craft drifting with the water over the bottom, and wind with respect to the sea bed as the "ground" or "geographical wind". The apparent wind on board (a boat) is often quoted as a speed measured by a masthead transducer containing an anemometer and wind vane
Wind power in Germany behind China and the USA. Since 1995, onshore wind energy has been an important and major industry in Germany. In 1995, the total onshore wind installed capacity was 1,530 MW. By 2018, onshore wind power installed capacity reached over 88 GW, which allows Germany to power about a fifth of the country from wind. Larger onshore installations are in the works, which could possibly see a larger percentage of wind energy powering Germany. Offshore wind energy also has great potential in Germany. Wind speed at sea is 70 to 100% higher than onshore and much more constant. A new generation
