Love the question starting with the words "do window acs waste the same amount of energy.."; if they waste rather than consume energy properly it is the fault of the operator.
However, if you are asking if an ac consumes more energy with the colder vs the warmer setting, which is what I assume you are really asking, the answer is very clear. To cool to a colder temp you must run the unit longer to remove the heat to the colder set point. You consume energy when the unit runs therefore, the longer it runs, the more energy you consume and the more it costs.
Be reasonable, not stupid. In hot weather, people dress in light clothes; in cold weather people dress in heavy clothes. Wearing winter weight clothing and expecting to run the a.c. to provide colder inside temperature is waste. Similarly, wearing summer weight clothing and expecting to run the heater to provide warmer inside temperature is waste.
The height of folly is seen by people who run their a.c. at a colder temp in summer than they run their furnace in winter. I know of people who heat to 72 in winter, cool to 68 in summer. What a foolish waste.
Frankly, cooling below 76 F in summer is waste; heating above 68 F in winter is waste.
Ac's deliver the same temperature air, usually, when the compressor is on which is usually 55.
It is a little higher when it is warmer outside.
They don't blow 65 and 72 degree air like some people believe.
At a 65 thermostat setting the compressor will come on until the room is 65, then go off. The same thing happens at 72, but the compressor stays on a shorter amount of time which uses less power (energy).
Less energy due to the less amount of times it is called for by the thermostat. When on 65, 72, 98 it draws the same amount when energized. The energy is saved by comming on less and turning off sooner.
