Researchers at the Hong Kong Polytechnic University claim to have developed the most energy-efficient Light Emitting Diode (LED) filament technology yet. Bulbs devised at the HKPU lab have a luminous efficacy of 129 lm/W. To be clear, the new bulbs employ LEDs shaped to look like the filaments of an incandescent light bulb. The light […]

Verizon Was Looking for Nearly a $1B Discount on Yahoo Deal Before It Got $350M Off
Yahoo apparently stuck to its guns in price renegotiations with Verizon following two massive data breaches revealed after the carrier had already inked a deal to acquire the troubled internet giant. According to a Monday filing with the Securities and Exchange Commission, Verizon CEO Lowell McAdam came to Yahoo at the start of last month seeking a […]
Deficiencies in energy efficiency tests of TVs get attention
H.R.117 – The Energy Efficiency Free Market Act of 2017 – introduced in Congress in January would prohibit the Dept. of Energy (DOE) from enforcing energy efficiency standards now on the books or setting new ones. If the Bill is enacted, one result will be making moot what seem to be misleading energy efficiency figures […]

Choppy waveforms confuse electronic energy meters
Some electronic power meters as used by utilities can give readings that are more than five times higher than actual energy consumption when the measured waveform is nonsinusoidal. So say researchers at the University of Twente (UT) in the Netherlands who collaborated with the Amsterdam University of Applied Sciences (AUAS) to measure the accuracy of […]
