Demand response (DR) programs, which aim to achieve stability on the grid by ensuring that demand does not exceed supply of electric power, have been offered to many electric customers in the United States for decades. In the last ten years, utilities and grid operators have adopted new technologies and practices to move demand resources to the next evolutionary phase, offering more advanced types of DR schemes. According to a new tracker report from Navigant Research, at least 1,342 DR programs are now underway worldwide – 95 percent of them in North America. Continue reading
GREEN ISLAND, NY–(BUSINESS WIRE)–Crystal IS, Inc., the leading manufacturer of proprietary, high-performance ultraviolet light emitting diodes (UVC LEDs) for monitoring, purification, and disinfection applications, has announced today that they achieved more than 65mW in optical output at 260 nm from a single UVC LED operated in a continuous mode. The details of this breakthrough were recently published in Applied Physics Express“This achievement is a technological milestone in the continued development of brighter, more efficient and reliable UVC LEDs. By employing die thinning and encapsulation techniques, we were able to increase the photon extraction efficiency to over 15%, “said Leo Schowalter, founder and CTO. “By fabricating our LEDs on our home grown aluminum nitride substrates, we continue to set the pace of what is possible for the combination of highest efficiencies and longest lifetimes in the 250-280 nm wavelength range, far surpassing diodes fabricated on sapphire.”
