Energy conversion efficiency is not defined uniquely, but instead depends on the usefulness of the output. All or part of the heat produced from burning a fuel may become rejected waste heat if, for example, work is the desired output from a thermodynamic cycle. Energy converter is an example of an energy transformation. For example a light bulb falls into the categories energy converter.
Even though the definition includes the notion of usefulness, efficiency is considered a technical or physical term. Goal or mission oriented terms include effectiveness and efficacy.
Generally, energy conversion efficiency is a dimensionless number between 0 and 1.0, or 0% to 100%. Efficiencies may not exceed 100%, e.g., for a perpetual motion machine. However, other effectiveness measures that can exceed 1.0 are used for heat pumps and other devices that move heat rather than convert it.
The energy efficiency of different types of transportation ranges from some hundred kilojoules (kJ) per kilometre for a bicycle to tens of megajoules (MJ) for a helicopter.
A 68kg (150lb) person walking at 4km/h (2.5mph) requires approximately 210 kilocalories (880kJ) of food energy per hour, which is equivalent to 4.55km/MJ. 1 US gallon (3.8L) of gasoline contains about 114,000 British thermal units (120MJ) of energy, so this is approximately equivalent to 360 miles per US gallon (0.65L/100km).
Energy efficiency is measured as the ratio of energy output to energy input, as a percentage. The goal of improving energy efficiency is to deliver the same service to the end user, using less energy. Learn more about energy efficiency at www.studentenergy.org

What is energy efficiency?
Efficiency means getting more for less. If we are efficient with energy, we can enjoy the same levels of comfort or more, while using less!

Energy efficiency
Amount of energy used to provide a service, for example to drive 100 kilometres. EU energy efficiency legislation requires products to be labelled with energy efficiency classes, outlaws inefficient equipment (ecodesign), and requires Member States to pursue energy savings targets and to take measures to promote energy efficiency.

Energy Efficiency & Conservation
Electricity has become an everyday necessity and it is a form of clean and convenient energy to improve our standard of living.
As such, more and more electrical appliances are used in business and home for enhancing the productivity and quality of life. There are various types / models of electrical appliances in the market and their energy efficiency performances may be substantially different from one another. You should select an appropriate appliance wisely to meet your requirements and use electricity smartly.

The Energy Efficiency Policy in Emerging Economies Training Week was held from 17 to 21 April at the IEA’s Paris headquarters. The IEA has been holding these week-long events since 2015, training more than 2,000 energy efficiency professionals from over 120 countries in total. The participants are primarily from government institutions and supporting organisations in emerging economies.
The sessions are dedicated to sharing experiences and best practices for planning, implementing, and evaluating energy efficiency policies in emerging economies. By focusing on building policy-making capacity in these countries, the IEA aims to expand its community of energy efficiency practitioners that can implement effective policy, helping to unlock this potential.
“All countries have different energy mixes, and different economic and social priorities, but one thing they all have in common is room to improve energy efficiency. It needs to be treated as the very first fuel, as it makes energy more affordable while supporting energy security and climate change objectives,” said IEA Executive Director Fatih Birol. “As the biggest opportunities to improve energy efficiency are in emerging and developing economies, they are the focus of our Energy Efficiency Policy Training Week, which has been going strong for many years now.”

How do solar panels work? - Richard Komp
View full lesson: https://ed.ted.com/lessons/how-do-solar-panels-work-richard-komp
The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy.

The International Energy Agency recently brought together over 120 policy makers and energy professionals from more than 40 countries at its energy efficiency training week in Paris to develop expertise in energy efficiency policy making and underline the important role it can play in emerging and developing economies.
The Energy Efficiency Policy in Emerging Economies Training Week was held from 17 to 21 April at the IEA’s Paris headquarters. The IEA has been holding these week-long events since 2015, training more than 2,000 energy efficiency professionals from over 120 countries in total. The participants are primarily from government institutions and supporting organisations in emerging economies.
The sessions are dedicated to sharing experiences and best practices for planning, implementing, and evaluating energy efficiency policies in emerging economies. By focusing on building policy-making capacity in these countries, the IEA aims to expand its community of energy efficiency practitioners that can implement effective policy, helping to unlock this potential.
“All countries have different energy mixes, and different economic and social priorities, but one thing they all have in common is room to improve energy efficiency. It needs to be treated as the very first fuel, as it makes energy more affordable while supporting energy security and climate change objectives,” said IEA Executive Director Fatih Birol. “As the biggest opportunities to improve energy efficiency are in emerging and developing economies, they are the focus of our Energy Efficiency Policy Training Week, which has been going strong for many years now.”

You may have been told that you cannot create or destroy energy, but we certainly use it - and pay for it, so what does get used up?
See our video https://youtu.be/Um04eHOqGlM where we explained that it is the usefulness of the energy that gets used as the energy is dissipated as waste heat.

Amount of energy used to provide a service, for example to drive 100 kilometres. EU energy efficiency legislation requires products to be labelled with energy efficiency classes, outlaws inefficient equipment (ecodesign), and requires Member States to pursue energy savings targets and to take measures to promote energy efficiency.

On the eve of COP28 the IEA will publish Energy Efficiency 2023, its latest Market Report which examines the global energy efficiency landscape and identifies key trends for governments.
This year’s report comes amid the enduring effects of multiple global crises and increasing urgency for stronger action to keep the 1.5 °C goal within reach. A main theme of this year’s report is the need to double global progress on energy efficiency this decade to get on track for net zero by 2050.
Join the public launch event to hear from IEA Executive Director, Fatih Birol, and IEA Head of Energy Efficiency and Inclusive Transitions, Brian Motherway, about the report’s key messages.
Electricity has become an everyday necessity and it is a form of clean and convenient energy to improve our standard of living.
As such, more and more electrical appliances are used in business and home for enhancing the productivity and quality of life. There are various types / models of electrical appliances in the market and their energy efficiency performances may be substantially different from one another. You should select an appropriate appliance wisely to meet your requirements and use electricity smartly.

✍ Learning material for this video: https://go.tfe.academy/21040704
In this video you will learn about the concept of ”energy conversion efficiency". We'll take a brief look at some of the most important terms, such as energy, work and power, and I'll show you an example in which we will determine the efficiency of an electric motor. And as always, there is a summary of the most important facts at the end of the video. So stay tuned!

The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy.
