    Prius: Depends on season, humidity, amount of sunshine (or not) that's getting into car and passenger preference.

    Home: Fall, Winter, Spring thermostats set at 68F day and 60-65F night. Daytime during these cooler seasons, amount of sunshine can increase house interior temperature significantly. Summer? Sometimes 78-79F, sometimes 76. Depends a lot on activity and occupant preference at the time. Ceiling fans allow comfort at higher Summer (78-79F) settings.

    I usually have my home set to around 74-76 depending on the day. In my car it depends much more greatly on the conditions. I usually don't set my A/C below 74, but if I have a lot of passengers I will to make sure they're comfortable.

    In the Prius - if it is over 90 outside (which it has been for several months), then Auto at 80. Once it gets to 100 or over, I'll probably up it to 85 or so.. haven't been through a winter with it yet!
    At home - in the summer, usually at 80 (with ceiling fans going!), in the winter, 65 (with the fireplace insert going!)

    Home, don't have AC, just ceiling fans in every room.

    Home: 66-68 in winter (little or no night setback since installing mini-split heat pump), Off in summer.
    Car: 65 when heat is needed, 76-78 when cooling is needed, LO the rest of the time.

    In the car: 78F or so (adjusted a lot) if A/C in use, LO most of the time, heat at minimum needed
    At home: 82F or so with fans on if A/C in use, windows open when possible, heat at about 60F or so (gives a nice boost in electronics performance).
    At work: Set to 73F (as measured at temperature probe points) year round by lab manager. Actual temperature at desk closer to 78F due to heat from equipment.

    Keep in mind, I live in the Arizona Desert. A/C is a huge part of my energy costs.

    Both my car and my home during the day are generally 78˚F Summer, 68˚F in the Winter. My home at night is 65˚F for heat.

    My car will sometimes be bumped to 71˚F heat, 76˚F A/C during earlier spring or if humidity is higher.

    I've looked at the scan gauge fuel flow on my car with the cruise control set to highway speeds, and the difference between A/C on and off is about 0.2gph (fuel flow is usually 1 GPH or less at a reasonable speed (1gph at 50mph is 50mpg)). Keeping higher temperatures (which are still far lower than 100˚F+ heat) helps A/C load to drop more quickly, which has a direct impact on fuel consumption.

    Same goes for heat. Lower heat settings require the engine to run less to keep coolant at a usable temperature. Fuel consumption improves, especially in city driving, with lower heat demand.

    I generally do not use the A/C unless it is over 100F. I do not use the heater unless the windows are fogging up.

    When I HAVE to use the A/C because my girlfriend is in the car I set it to 75/78F depending on what she finds comfortable. I pretty much give up on fuel efficiency when she is riding in the car and just try to keep her happy. :) My mpg average usually drops by 5mpg or more due to speed and A/C use. lol

    In theory, if you are driving a long distance on the interstate at 60+ mph then it probably doesn't matter how much you use the heater since it is just pulling excess heat off the ICE, right?

    I live in the valley of the sun (phoenix metro).
    Summers are brutal.

    Prius: My AC I just use the up and down button leaving it on 75. I don't think I have it on auto though.
    Winters are mild here. I just use it early in the morning mostly. I just turn it up to high and put the up and down vent button on the lowest setting after it warms up.

    Home: Try to keep at as high as possible and try to be comfortable with 80, when i go to bed i need to drop it to 77-78. Winter it gets very cold in my unit so around 72-73 is comfortable. Leaving it in the 60s is just too cold for me but at night aside from a few cold weeks in Dec and possibly January, I turn my heat off.

    Prius is set at 72
    My home is not airconditioned, but the heat is set at 70 daytime and is off at night.
    I live in Southern California near the beach.:)

    House: 76 A/C (this year, I'm at 75 because I'm starting home brewing) and 68 Winter
    Car: A/C fluctuates between 74-80 depending upon situation. Heat? What's that? Usually 68, but only if others are in the car or it's a long trip or conditions make it necessary. Otherwise, it's off.
