In general, turbines use energy to start up! They need to do this in order to overcome the very large inertia. Imagine a wind that lasts for 4 hours, but to harness that, you need to be spinning up for 1 hour, leaving you only 3 hours or useful energy. Instead, they spin up the blades to the optimum speed and can get payback for that initial spent energy. Also, you still need energy to run the computer that monitors everything. https://oilprice.com/Alternative-Energy/Wind-Power/How-Much-Power-Do-Wind-Turbines-Use.html https://oilprice.com/Alternative-Energy/Wind-Power/How-Much-...
