Compressed Air Energy Storage (CAES)
A method of storing energy by using surplus electricity to compress air into a cavern or vessel, then releasing it later to drive a turbine and generate electricity.
Electromagnetic induction
The production of a voltage in a conductor when it experiences a changing magnetic field (or when it moves through a magnetic field).
Energy transformation
Change of energy from one form to another within a system or across interacting systems.
Renewable
An energy resource that is naturally replenished on a short timescale compared with its rate of use, so it can be used sustainably if managed properly.
Step-Down Transformer
A transformer that decreases voltage from the primary coil to the secondary coil (secondary has fewer turns).
Step-Up Transformer
A transformer that increases voltage from the primary coil to the secondary coil (secondary has more turns).
Transformer
A transformer is a device that changes the voltage of an alternating current (AC) using the principles of electromagnetic induction.
Turbine
A turbine is a device that rotates when a moving fluid such as steam, water, or air flows over it.
