Define The Efficiency Of An Energy Converter

For example a light bulb falls into the categories energy converter.

Define the efficiency of an energy converter.

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. Energy conversion efficiency is the ratio between the useful output of an energy conversion machine and the input in energy terms. Improving this conversion efficiency is a key goal of research and helps make pv technologies cost competitive with conventional sources of energy. 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.

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. A solar energy converter for instance converts radiant energy from the sun into usable electricity that can be used to power electrical devices. 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. The useful output may be electric power mechanical work or heat energy conversion efficiency is not defined uniquely but instead depends on the usefulness of the output.

Energy efficiency and its practices are a part of a sustainable energy policy. Energy converter is an example of an energy transformation. 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. During the following years california s energy consumption has remained.

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.
