Energy conversion efficiency - Wikipedia
Energy conversion efficiency (η) is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be chemical, electric power, mechanical work, light (radiation), or heat. The resulting value, η (eta), ranges between 0 and 1. [1][2][3]
Energy Conversion Efficiency - an overview - ScienceDirect
The definition of the energy conversion efficiency is the useful energy output (benefit) divided by the energy input (cost). Energy can be divided into quantity and quality terms. For electric power, quantity and quality are described by current and voltage, respectively.
Greater energy efficiency can reduce energy costs to consumers, enhance environmental quality, maintain and enhance our standard of living, increase our freedom and energy security, and promote a strong economy.
Energy conversion - Conservation, Transformation, Efficiency
Energy conversion - Conservation, Transformation, Efficiency: A fundamental law that has been observed to hold for all natural phenomena requires the conservation of energy—i.e., that the total energy does not change in all the many changes that occur in nature.
Energy conversion | Definition, Examples, Formula, Principle,
Many of the energy converters widely used today involve the transformation of thermal energy into electrical energy. The efficiency of such systems is, however, subject to fundamental limitations, as dictated by the laws of thermodynamics and other scientific principles.

Energy Efficiency is providing the same or better service using less energy. Conversion Efficiency measures how well energy is converted from one form to another as shown in the energy system examples below.
Common energy conversion strategy: just mix a fuel with air, and let the reaction run to completion. Then extract work from the hot exhaust gases. Usually the conversion of chemical energy to heat is irreversible: large increase in entropy. For transportation, need to carry the energy conversion equipment with you!
7.6: Conservation of Energy - Physics LibreTexts
Define efficiency of an energy conversion process as the fraction left as useful energy or work, rather than being transformed, for example, into thermal energy. Energy, as we have noted, is conserved, making it one of the most important physical quantities in nature.
