I had a nervous experience today so I'm looking for information on how to factor in use of the air conditioning. Today I started on a 60 mile round trip via highway and farm roads in the 90 degree heat. A/C was set on 9 at 68 degrees. Starting out I had a 90 mile charge. When I got home it was down to 8. To conserve energy I turned off the A/C on my way home. Question: How much energy does air conditioning consume? Took delivery of my Model 3, btw, less than two months ago.
