I would assume it means that the more efficient it is, the less energy it intakes and the more efficient the system is at retaining the energy it intakes.
Gas-fired, storage-based water pumps are the most energy efficient type.
It's a device that can convert energy of one form into another efficiently. Like a lightbulb for example, an energy efficient one would use less electricity but still produce as much light as one that is less efficient. It's a measure of what you get out versus what you put in.
A Sprayed Polyurethane Foam (SPF) coating will be very durable and has been proven the most energy efficient roofing system on the market today.
