How can I measure the dollar amount of savings from tree shade on my power bill?

While there are many variables to account for, such as climate, home insulation, HVAC type, etc., research conducted at Auburn University found that with 17% shade on your house, your power bill will decrease by $10 per summer month (when your air-conditioner is running). If shade were to increase to 50% over your house, this translates to a savings of $30 per month.

Arbor Day has a neat tool you can use to calculate savings based on customized situations set by you.
