ENVIRONMENTAL IMPACTS OF ENERGY-EFFICIENT TECHNOLOGIES: POTENTIAL FOR INPUT-OUTPUT AND SUPPLY-CHAIN ANALYSES IN IRAN

Challenges of minimum-energy operation in sub-65nm technologies

The increased performance from technology scaling makes it tempting to operate digital circuits at ultra-low voltages, which would have resulted in very low performance in earlier process generations. Even though the theoretical minimum energy point (MEP) resides in nearor subthreshold voltages in current processes, device and environment variations make it a challenge to operate the circuits r...

10. Energy Efficient Technologies in Electrical Systems

High-tension (HT) consumers have to pay a maximum demand charge in addition to the usual charge for the number of units consumed. This charge is usually based on the highest amount of power used during some period (say 30 minutes) during the metering month. The maximum demand charge often represents a large proportion of the total bill and may be based on only one isolated 30 minute episode of ...

Energy Efficient Storage Technologies for Data Centers

An impressive amount of work has been done to date on improving the electrical efficiency of various data center components. The data storage industry has begun to see the fruits of this effort, with increased power supply and fan efficiencies. However, storage presents other significant opportunities for energy conservation, through various types of capacity optimization, that are not captured...

Toward Energy-Efficient 5G Wireless Communications Technologies

The densification and expansion of wireless networks pose new challenges on energy efficiency. With a drastic increase of infrastructure nodes (e.g. ultra-dense deployment of small cells), the total energy consumption may easily exceed an acceptable level. While most studies focus on the energy radiated by the antennas, the bigger part of the total energy budget is actually consumed by the hard...
