A percentage is always a comparison of two numbers. It is not clear what two numbers (amounts of energy) you want to compare in this case.
Reducing energy use is called energy conservation and efficiency is the percentage of energy that is actually used to perform work the rest of energy that is '' lost '' to the surrondings.
It depends on the efficiency of the machine. No machine is perfect and there are always losses and waste. Usually the losses are a greater percentage than the useful energy.

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.

The order of energy sources from highest to lowest percentage of worldwide use is: oil, natural gas, coal, and renewable energy sources (including hydropower, wind, solar, and biomass).
90% of athletes use energy drinks because they essentially rely on it to improve their performane of which in some cases, it does.

The ratio of useful energy output to total energy input is known as the energy efficiency. It is calculated by dividing the useful energy output by the total energy input and multiplying by 100 to express it as a percentage. A higher energy efficiency percentage indicates a more effective use of energy resources.
you use energy in you body by, exercising, or any major or minor movement during the day or night.
