Wind Characteristics, Wind Speed and Energy

Wind Characteristics. As the wind power is proportional to the cubic wind speed, it is crucial to have detailed knowledge of the site-specific wind characteristics. Even small errors in estimation of wind speed can have large effects on the energy yield, but also lead to poor choices for turbine and site. An average wind speed is not sufficient.

How Much Energy Does A Wind Turbine Produce?

Pretty windy. A shut-down wind speed of 25 m/s is 56 mph or 48.6 knots. This shows that wind turbines have a wide operating window for stronger winds. At the lower end, a minimum wind speed of about 5 m/s is often considered necessary for a wind turbine to be viable. This is 11 mph or 9.7 knots.

Wind – Renewables 2020 – Analysis - IEA

Annual net wind capacity additions are expected to reach 65 GW in 2020, 8% more than in 2019. Covid‑19 measures led to onshore construction activity slowing down from February to April due to supply chain disruptions and logistical challenges in many countries, but the offshore wind sector has been only mildly affected by delays caused by the Covid‑19 crisis due to long project lead times.
