Applied Science AQA/Energy and Efficiency

Setting Applied context
It is useful for energy consultants to be able to compare the efficiency of different devices in our homes and workplaces. Energy is transferred by different devices, and the rate at which energy is transferred is called ‘power’.

Architects and energy consultants use U values to measure how effective different materials used in buildings are as insulators. That is, how effective they are at preventing heat energy from transmitting between the inside and the outside of a building.

Exploration of key ideas (must be original text, not C&P) – level checked by AQA
In general, point students towards the approach to take, as opposed to just giving them information.

The meaning of efficiency
Efficiency is a measure of how much work or energy is kept and not lost in a process. in many processes, work or the energy is lost, this can be through heat or sound. the efficiency is the energy output, this is divided by the energy input and is expressed as a percentage. A perfect process would of an efficiency of 100%.
