The authors assume that reactive jammers can be considered energy-efficient.
The procedure is done by using multi-hop routing which is not considered energy efficient.
Since the energies which are consumed during the transmission or reception are concerned with the communication process, so they can be considered the efficient energy consumption.
Self-compacting concrete (SCC) is considered an energy efficient material; because it reduces on-site working and does not need any compacting energy.
LED light bulbs are more expensive but last much longer than filament or fluorescent bulbs and therefore are considered more energy efficient.
Electrohydrodynamic (EHD) drying is considered as energy efficient non-thermal technology suitable for dewatering of heat-sensitive materials, including food products.
This enhancement shows that nanofluids can be considered as potential energy efficient heat transfer fluids.
Factors such as solar heat gain in summer, heat loss in winter, and natural ventilation in transitional seasons must be considered when designing energy-efficient residential buildings for hot summer/cold winter zones.
Thermal conductivity is an important property of rocks which is considered for energy-efficient building construction.
Time Division Multiple Access TDMAA) protocols are considered an energy-efficient solution to prolong wireless sensor network lifetime.
