What is the reason that ARM based CPUs (for mobile devices) are more power saving than x86 CPUs?

Question by Rishabh Singla: What is the reason that ARM based CPUs (for mobile devices) are more power saving than x86 CPUs?
More specifically, is ARM architecture itself responsible for ARM based CPUs consuming less power, or are x86 based CPUs (for mobile devices) more power hungry only because nobody (Intel and others) has made them power saving yet?

So is the architecutre (ISA etc) itself responsible for power saving, or is there some other reason?

Why are Fuzzy Logic air conditioners more energy efficient than Thermostats?

Question by Neil S: Why are Fuzzy Logic air conditioners more energy efficient than Thermostats?
It’s common knowledge that through the use of carefully crafted Fuzzy Logic rules, an air conditioner can be more energy efficient than a thermostat. What I am curious to know is WHY this is so.

Thanks!

Best answer:

Answer by PredictorTwo factors contribute to this increased efficiency:

First, fuzzy logic control can take advantage of air conditioning machinery which can be set to different levels of output. A thermostats is simply a thermometer, with an electrical switch set to turn “on” when the temperature exceeds the selected threshold. [...]
