Some of this may have changed in the patch. Health is worth more now. External trade routes really got nerfed so energy and science are somewhat harder to come by.
Of course these numbers are only rough estimates anyway. Most of the yields have diminishing returns. Virtues and population increase in cost with each one. The lower tier buildings tend to be more efficient production/energy wise, so as your production and energy increase you end up spending it less efficiently. There comes a point where extra health does nothing. Energy becomes worth a lot more when you have so little your units are in danger of disbanding. Science seems to be the only yield without diminishing returns, at least until you've unlocked whatever victory condition.
