Step 1: Chop down a tree that shades your home.
Step 2: That’s it.
Results:
Your air conditioning bill and electrical energy usage during peak summer cooling seasons will go up since the roof is exposed to the sun during the hot summer days.
You house will be hotter and more uncomfortable during the summer if you don’t use the A/C, or…
You will be more dependent on an unreliable electrical grid to keep your house comfortable.
You are highly likely to use more air conditioning and have to replace your air conditioner more often.
The bugs, birds, squirrels, and other wildlife that lived in the tree will be gone.
Note: If you have already cut down your tree, you can put some solar panels on that roof to reduce the damage a little bit.
