emiconductor technologies are so essential to advances in energy efficiency gains that the U.S. economy could expand by more than 70 percent through 2030 and still use 11 percent less electricity than it did in 2008, according to a major new study by the nonprofit and independent American Council for an Energy-Efficient Economy (ACEEE).

Titled Semiconductor Technologies: The Potential to Revolutionize U.S. Energy Productivity, the new ACEEE report concludes that semiconductors already are the leading factor behind energy efficiency gains. The report states: “Compared to the technologies available in 1976, we estimate that the entire family of semiconductor-enabled technologies generated a net savings of about 775 billion kilowatt-hours (kWh) of electricity in the year 2006 alone … Had we expanded the size and scope of the U.S. economy based on 1976 technologies, it appears that the U.S. would be using about 20 percent more electricity than actually consumed in 2006. Stated differently, had we continued to rely on 1976 technologies to support the U.S. economy today, we might have had to build another 184 large electric power plants to satisfy the demand for goods and services.”

In addition to eliminating the need for 184 additional power plants, the estimated 775 billion kWh savings in 2006 attributed to semiconductor-enabled technologies also can be expressed as: $69 billion dollars in business and consumer savings (or $613 per U.S. household); enough power to keep 64.5 million U.S. households going year round; and the prevention of 479 million megatons of carbon dioxide (CO2) equivalent emissions prevented – a 20 percent cut in electric utility industry emissions linked to climate change.
