It might be more fruitful to discuss your feedback in the Discord, so people can address them point by point. That tends to be a better platform for complex discussions.
Wind turbines needing to be spread out so much limits how much you can scale them easily. It costs time running around, it costs power poles, and the unpredictability adds energy storage demands. It's possible to get all your power from wind, but it's possible to get all your power from any of the other methods if you really want to. Some people really like geothermal, think geothermal is overpowered, and hate wind.
I don't know what you mean about water from steam equaling wind power. It's an energy storage option rather than an energy production method like wind. It does add a lot of complexity and infrastructure cost, since wind power relies on much more energy storage than other generation methods. The cost of wind turbines is deceptively low, but it gets a bit more expensive once you account for the storage costs. Electrolysis is also not 100% efficient, particularly at lower tech levels, so some of your wind energy is lost when stored.
I'm assuming the "other recipes" in this context is referring to other combustion chamber recipes for steam, but I'm not sure because you're covering multiple topics here. The combustion recipes are not intended to be more energy efficient than simple electrolysis. Rather they're options for voiding excess hydrocarbons, since you may not synthesize them in precisely the same ratio that you consume them.
Hydrogen is a simple but effective energy storage option, both in Nullius and in the real world. One important alternative to that is compressed nitrogen. You get a lot of free nitrogen as a byproduct, and compressed nitrogen is even easier to use than hydrogen.
Not sure what the "lol" is suggesting, as "air" is not synonymous with "oxygen". Lots of exoplanets have atmospheres. Most of them don't have free oxygen. E.g. Mars has a thin atmosphere consisting mostly of carbon dioxide. Nullius has a thicker atmosphere than Mars, more similar to primordial earth, back before bacteria started producing oxygen.
