| The Role of Semiconductors in Clean Technologies | ||||||||||||||||||||||||
Semiconductors play a key role in our daily lives. They are used in everything from greeting cards to satellites, and form the basis of all modern electronics. There are over 500 billion semiconductor devices sold each year. In much the same way as energy enabled the industrial revolution, semiconductors enabled the technology revolution. In order to sustain these advancements, however, we need to develop sources of clean renewable energy and learn how to use that energy more efficiently. Semiconductors can and do play an important role in both of these areas. Semiconductors are the basic material from which photovoltaic cells are made, and they are used to control PV systems and wind turbines (as well as all conventional power plants). Integrated circuits are also used to improve the efficiency of nearly all energy consuming products, including automobiles, appliances, lights, and consumer electronics. Beyond enabling clean energy sources and improving energy efficiency, semiconductors can help promote a sustainable future by enabling new more energy efficient lifestyles such as telecommuting and on line commerce. While semiconductors play a key role in clean energy, these devices are also becoming significant consumers of energy themselves. Data centers consume over 1% of all electricity used in the US, and that amount is on the rise. Add to that the energy consumed by semiconductors in PCs, telecommunications systems, and consumer electronics, and it becomes clear that energy efficiency within semiconductors themselves is an important issue. This panel session will address the role of semiconductors in enabling clean technologies. Panelists will address questions on applications of semiconductors in clean technologies as well as the development of more energy efficient semiconductor devices. Topics will include:
