  1. there's some inconsistency here. A mix between sources of energy and forms of energy. Sources may be: human, animal, wind, water, solar, etc. Forms might be mechanical, thermal, electrical, light, etc. We have human and wind under electrical, but windmills can be used for, yep, mills, or for pumping, with no electricity involved. Solution? A more complete subcategorization by energy form, or by source, or possibly both
  2. Highlights the categorization problem. Need a "lighting" section
  3. Subcategories may not be needed
  4. Category:Biofuel already exists...

Hey, all:

Forgive me, but I must be blunt. Some misguided focus has created many many details unsupported by some fundamentals. There needs to be topics on the 2 most sustainable sources of generating electrical energy: one is "Solar Energy", and the other is "Wind Energy". Subcategories for each should include at least 2: "Small Scale (Residential/Business)" and "Utility Scale". I had the editing skills, I would add them, but I still need to learn.

Pay attention to the basics.
