A/C and heating can drain power from the engine, forcing it to work harder and reducing fuel economy.
Tips for efficient climate control:

Pre-condition the cabin while the car is plugged in if the Prius has a plug-in version.
Use the A/C sparingly, especially in moderate temperatures.
In cold weather, use the heated seats instead of the heater when possible.
