Energy Efficiency is defined as the energy conversion ratio between the useful output of an energy source (eg. generator, or battery), and the desired input (eg. homes, buildings, electrical motors). The useful output may be electric power, mechanical work, or heat.
Energy is wasted when significant losses occur during generation (30%), during transmission across high voltage power lines (10%), and lost as over-engineered solutions, heat & friction in pumps and motors that fill our homes and workplaces (50%). Another 5% is wasted when products are discarded to landfil within the first 3-6 months of purchase. Energy Efficiency can be increased by incorporating passive design and renewables into Buildings, Transport, Industry, and Electricity generation.
Energy Efficiency is best optimised when considered using a "whole-system approach".
The problem of Wasted Energy requires resolution prior to building more supply infrastructure, and only when efficient demand requires it.
