Define the efficiency of an energy converter.

Energy conversion efficiency is a term used to describe the amount of useful energy output that results from a given energy input in a device used to convert energy from one form to another. Energy efficiency has proved to be a cost effective strategy for building economies without necessarily increasing energy consumption for example the state of california began implementing energy efficiency measures in the mid 1970s including building code and appliance standards with strict efficiency requirements. Improving this conversion efficiency is a key goal of research and helps make pv technologies cost competitive with conventional sources of energy. The conversion efficiency of a photovoltaic pv cell or solar cell is the percentage of the solar energy shining on a pv device that is converted into usable electricity.

Energy efficiency can be achieved with renewable sources of energy such as solar wind or hydro or by changing the power consumption requirements so that the overall energy consumption is reduced without compromising the output received. A solar energy converter for instance converts radiant energy from the sun into usable electricity that can be used to power electrical devices. An energy efficient fridge will use less energy than an old model but still keep your food cool while an energy efficient washing machine will get your clothes smelling fresh and clean without using as much power as an older version. Energy conversion efficiency is the ratio between the useful output of an energy conversion machine and the input in energy terms.

Look it up now. Energy efficiency and its practices are a part of a sustainable energy policy. The term energy efficiency can also be used in a wider sense. Nonetheless improving energy efficiency is a key tool for reducing co2 emissions alongside energy conservation and low carbon energy sources such as renewables and carbon capture and storage.

Even though the definition includes the notion of usefulness efficiency is considered a technical or physical term.
