According to the U.S. Department of Energy, energy consumption for all lighting in the United States is estimated to be 8.2 quads, or about 22% of the total electricity generated in the U.S. and one-fifth of the national electrical consumption. It is estimated that consumers and businesses in the US spend approximately $37 billion a year to light their homes, offices, streets, and factories. Advanced lighting technologies can significantly improve the energy efficiency of lighting and reduce building energy consumption and costs. Energy efficiency in lighting is the ability to use less energy to produce the same amount of light output, with the same quality and performance. Technological advances in the past decade have improved the energy efficiency of lamps and ballasts by 30%-60%, resulting in lower utility bills and reduced environmental impacts. Using less energy reduces emissions of carbon dioxide, air-borne mercury, and other harmful pollutants from power plants that burn fewer fossil fuels to meet the lower energy demand. Lamps with longer life require fewer replacements, reduce the demand for raw materials and lower recycling costs. PIDC is also seeing a growing opportunity to serve the display materials market, as the industry for displays used in televisions and computers continues to migrate to China. Plasma based flat screen televisions and notebook computer monitors utilize formulated materials for more intense light transmission. |
