An informal description of energy transferred into stores where it is not wanted and is less useful, rather than energy that has disappeared.

Wasted energy = 100 − 60 = 40 J. Efficiency = 60 ÷ 100 × 100% = 60%. Arrow shaft widths are proportional to energy.

Energy transferred in a way that does not serve the intended purpose of a device or process.

Remember that “wasted” describes usefulness, not conservation: wasted energy still exists and must be included in the energy balance.
