Those big turbines are available in two zero carbon power sources:<br><br>Hydroelectric and nuclear power.<br><br>Probably in geothermal as well if it is large scale enough.<br><br>And shouldn't all those thousands of tiny generators create a little bit of the inertia from the one power plant they replace?,(reply>), I believe you mean the small generators inside wind turbines. Most modern wind turbine generators are connected to the grid through a power converter, partly or entirely decoupling the rotational speed of the generator from the grid frequency. Therefore their inherent inertial response is close to or exactly zero. There is a possibility however to programe the converters to inject inertial power (slowing the turbine rotor) when needed and vice versa. There would be some time delay, although quite small. There are also limitations in rotor rotational speed. Anyhow, if you want to know more about this, research synthetic (artificial, emulated) inertia.
