> Wind and solar is actually pretty easy to throttle back in principle; wind turbines need to have braking capabilities anyway in order to handle high winds Also, many wind turbines are variable pitch: the angle of the blades can vary, so the controller can put them in a less efficient position to reduce the turbine power, or "feather" them to produce no power (the brake is also used in this case to completely stop the rotation).
