Energy required to ionize a gas into plasma

[JoeSalerno]

I may be grossly generalizing the principle, but is there a way to calculate the energy needed to transform a solid/liquid/gas into plasma? Information is easily found on enthalpy of fusion/vaporization/sublimation, but I couldn't find anything regarding transforming to the 4th state of matter. Is it not possible because of how plasma is "made" with the process being more complicated than applying heat?

https://en.m.wikipedia.org/wiki/Plasma_(physics)#TemperatureIt may be hard to define because the plasma can be partially ionized, the atoms partially ionized, and the average kinetic energy can vary.

Interestingly, the wiki article says that plasma temperature is sometimes expressed in electron volts which is a measure of energy.
