The energy used is electricity.
The air conditioner itself does not release any carbon or carbon dioxide. But if the energy to power the air conditioner comes from a coal fired power plant, it takes more energy to reduce the temperature of a room than it does to heat it.
Electrical energy
The type of motor commonly used in an air conditioner is called a compressor motor.
mechanical, electrical, sound, thermal, chemical, light, solar, and nuclear
A motor is used to power a windmill.
The main type of output energy in a circuit is typically electrical energy, which can be in the form of voltage, current, or power. The output energy is often used to power devices or do work within the circuit.
energy
Renewable. It uses the movement of the oceans to generate electricity when it is used for power.
Batteries store energy in the form of chemical energy, which is converted to electrical energy when the battery is used to power a device.
Gasoline is used for the energy to power a car.
Electrical energy is due to the movement of electrons. This type of energy is commonly used to power various devices and electrical systems.
The equipment might have circuits which remain energised when it is in an off-cycle, but the energy used would probably be less than 1% of the energy used in the on-cycle.
