What compares the energy output of a system with its energy input?
Is it's Energy Efficiency.
When was British Energy Efficiency Federation created?
British Energy Efficiency Federation was created in 1996.
What is the percentage of energy used to do work called?
The term EFFICIENCY is defined as useful work, divided by total energy expenditure.
What is the purpose of the CRC Energy Efficiency Scheme?
The CRC Energy Efficiency Scheme is aimed at improving energy efficiency, as well as cutting emissions in large public and private sector organisations.
What is an energy efficiency paradox?
An energy efficiency paradox is when there is a high demand for energy as much as there are new developments in trying to reduce its consumption
What is mean of pump efficiency?
The ratio between the energy efficiency of pumps and pump uses the energy that does. Pump efficiency is determined by the manufacturer. In the calculation of pump efficiency is 70%.
How is vehicle energy efficiency determined?
By how much smoke you have blowing out your tail pipes.
The efficiency of each stage of energy production can be determined by?
The efficiency of each stage of energy production can be determined by measuring the net amount of ATP produced. During the initial steps of respiration there is a net of 2 ATP, by the oxidative phase there is a net of 36 ATP produced.
What is the coal energy efficiency?
If it is burned - which is the way such fuels are usually used - the energy efficiency is the energy efficiency of a heat engine. The theoretical maximum efficiency is the Carnot efficiency; the real efficiency will usually be considerably less than that.
What does the SEER rating say about an air conditioner?
The SEER metric is used to measure a heating and cooling systems performance, which is determined largely by the HVAC equipment operating efficiency. SEER stands for Seasonal Energy Efficiency Rating.
What is the efficiency of propane for space heating?
The efficiency of the fuel is determined by the appliance that is burning it, not the fuel itself.
The percentage of energy from a fuel that is actually used to perform work is its?
That is called efficiency. An efficiency of 1 (or 100%) means that all the energy is converted into useful work.That is called efficiency.

The term EFFICIENCY is defined as useful work, divided by total energy expenditure.
What is the efficiency of a transformer?
The "all day" efficiency of a transformer is defined as the ratio of energy out/energy in for a given all day cycle.
Why can't the efficiency of a device or a process be greater than 100?
Efficiency cannot be greater than 100% because efficiency measures energy, and since energy is not made, only transfered (conservation of energy) then we cannot gain energy. Hence the energy out must be at most the energy in. Thus efficiency can be at most 100%
How long does energy efficient light bulbs STAY ON?
As long as they receive energy. The energy-efficiency refers to the fact that less energy is wasted as heat.As long as they receive energy.
