Yes, Oldfeller, I looked at the data, and where it said "[trees] can reduce energy consumption for air conditioning by up to 30%." That sounds plausibile, but I have my electric bills, and I did not experience any reduction. I go by the number of kwh used, not the price, since electric rates change over time.
Somewhere in my older records I also have my plumbing bill where I paid for a water line replacement when my Bradford Pear tree roots grew into and clogged my PVC pipe when I used to live in Dallas. Not only did the line need replacing, but the tree died anyway the following year, so there was the added expense of removing it.
And, "shade can reduce heat stress in the human body." Yes, that I agree with. Texas summers can be intolerable, so most of my time is spent indoors, but if I want to go outside, I have a huge covered patio right off my bedroom that provides all the shade and privacy I need.
