Simple measures can keep problem of inefficient "network standby" from worsening in years ahead, IEA report says Around $80 billion wasted on power for online devices in 2013
Energy efficiency is a way of managing and restraining the growth in energy consumption. Something is more energy efficient if it delivers more services for the same energy input, or the same services for less energy input. For example, when a compact florescent light (CFL) bulb uses less energy (one-third to one-fifth) than an incandescent bulb to produce the same amount of light, the CFL is considered to be more energy efficient.
The IEA promotes energy efficiency policy and technology in buildings, appliances, transport and industry, as well as end-use applications such as lighting. IEA analysis has led to the development of 25 energy efficiency recommendations which identify best-practice, highlighting the opportunities for energy efficiency improvements and policy approaches in each sector to realise the full potential of energy efficiency for our member countries.
