1. Remove the "Notes about Energy" header. That sort of basic information belongs at the top of the article, while sections are used for greater detail.
2. Matter Converter, not Metal. Similarly, there's a bunch of redlinks because they are the plural form of the article you wanted. Put the singular form in the brackets and add the plural modifier afterwards (ex. [[Fortress]]es).
3. I think the information under "Energy Debt" is incorrect. I remember having a brownout at -90k, and it only knocked out my forcefields, grav turrets and tractor beams. The other turrets kept working.
