This category does not require a rating on Wikipedia's content assessment scale.
Note: On Dec. 18, 2008 I undertook a comprehensive cleanup of the sub-categories that were listed here. This resulted in a reduction from 20 down to 11 sub-categories that actually belong here. Please use good judgement and don't use this category as a dumping place for all sorts of energy categories that seem to be related to economics in some way or other. Doing that defeats the whole purpose of categorization. Thanks, I hope. Cgingold (talk) 15:39, 18 December 2008 (UTC)Reply
