Energy Consumption in a PC : Hardware and software components that affect the most the consumption

The field of Information and Communication Technology (ICT) has been historically and fairly considered as a key factor for developing innovative control systems and services, which can help in reducing and monitoring third-party energy wastes and in achieving high levels of efficiency. In such context, different projects considered and/or developed networked technologies in order to build smart environments (e.g., houses, buildings) that are also energy-aware. At present, the role of ICT is becoming of paramount importance in addressing better energy efficiency in the energy production and distribution sector, as well as in fostering energy-awareness in all aspects of production and services. It would be odd that ICT would not apply the same concepts to itself.
