Why is Energy Access Not a MDG?

The UN Millennium Development Goals (pictured above) focus attention on helping improve the lives of poor people around the world.  In the words of the UN:

[The eight goals] form a blueprint agreed to by all the world’s countries and all the world’s leading development institutions. They have galvanized unprecedented efforts to meet the needs of the world’s poorest.

Question: Why is energy access not among the goals?
