Energy efficiency is desirable because it helps reduce energy consumption and lower utility bills. It also helps reduce environmental impact by lowering greenhouse gas emissions and promoting sustainability. Additionally, energy efficiency can improve the overall comfort and performance of buildings and appliances.

Why a high-efficiency machine is more desirable than a low- efficiency machine?
High-efficiency machines do more for less and are therefore more desirable than a low-efficiency machine.AnswerHigher efficiency means lower energy losses and, therefore, such machines are more economical than low-efficiency machines.
Describe why a high-efficiency machine is more desirable than a low-efficiency machine?
Efficiency is the ratio of the energy converted into useful work by the machine to the energy supplied to the machine. Certainly it will not be possible to convert all the energy supplied into useful work because of wastage of energy due to so many reasons. So efficiency will be always less than 1. As the efficiency becomes more the loss would become less. Hence it is desirable.
What compares the energy output of a system with its energy input?
Energy efficiency compares the energy output of a system to its energy input. It indicates how much of the input energy is converted into useful output energy, with higher efficiency values indicating less energy wasted.
What is the equation to calculate energy efficiency?
Energy efficiency is typically calculated as the ratio of useful energy output to total energy input. The equation to calculate energy efficiency is: Energy Efficiency = (Useful Energy Output / Total Energy Input) x 100%.
What is conversion efficiency of photovoltaic cell?
The conversion efficiency of a photovoltaic cell refers to the percentage of sunlight that is converted into usable electricity. Higher efficiency cells can convert a greater percentage of sunlight into electricity, making them more desirable for solar energy applications. Typical conversion efficiencies for commercial photovoltaic cells range from 15% to 22%.
Describe why a high-efficiency machine is more desirable thana low-efficiency machine?
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).

What is light use efficiency?
Light use efficiency refers to the efficiency with which plants convert light energy into chemical energy through photosynthesis. It is a measure of how effectively plants capture and utilize sunlight for biomass production. High light use efficiency is desirable for maximizing plant productivity.

What objective is always desirable in human movement?
Efficiency is always a desirable objective in human movement. It allows individuals to achieve tasks with minimum effort and energy expenditure, enabling better performance and reducing the risk of injury.
What is the order of the desirable coal to least desirable?
The order of desirable coal types from most desirable to least desirable typically follows this hierarchy: anthracite, bituminous, sub-bituminous, and lignite. Anthracite is the highest rank, known for its high carbon content and energy efficiency. Bituminous coal is widely used for electricity generation and steel production, while sub-bituminous has lower energy content. Lignite, being the lowest rank, has the least energy density and is primarily used for electricity generation in power plants.

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.
Why does a high-efficiency machine is more desirable than low-efficiency machine?
High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.
When was British Energy Efficiency Federation created?
British Energy Efficiency Federation was created in 1996.
