Light-emitting diode (LED) technology seems to be all the rage in the lighting industry, and those in the know are more than aware of its many benefits. However, for the average consumer, the world of LEDs is still an unknown.
The intermittent nature of some forms of renewables—solar and especially wind—make storage technology an essential ingredient of their success. Storing the power generated from renewables allows it to be used at times when demand is high and generation is low.
On Jan. 12, 2015, passengers on a Washington Metropolitan Transit Authority (WMATA) Metrorail train were trapped for some 40 minutes in the tunnels between two downtown D.C. stations, while smoke filled the air, according to the Washington Post.
The Consumer Electronics Show (CES) is not typically an event that draws electrical contractor interest, but this year’s show raised some eyebrows in the low-voltage market. An influx of products demonstrated that ECs could be pulled further into the high-end consumer market.
Along with many new trends that electrical contractors are finding themselves involved with these days, there are some surprises. While ECs have traditionally wired the power for elevators, much of the work has been left to mechanical contractors.
Electri International, a foundation that supports electrical industry research, released “Customer Side Smart Grid Installations—Preparing for the Future,” a report that examines how implementation of the smart-grid technology is changing the nature of the electrical distribution system in the Unite
The Sistine Chapel has an interesting history with light. For hundreds of years, it was primarily illuminated by candles, but the smoke left a layer of soot on the artwork, which had to be restored. Preserving Michelangelo’s masterpiece has been of prime concern.
The incandescent “ban” has returned to the Congress floor. This time, Congress passed a $1.1 trillion funding bill that would keep the federal government operating until September 2015, but the bill carried various policy provisions that affect current and upcoming laws.
In the pursuit of technological innovation and alternative-energy sources, California has a well-established reputation as a pioneer. That reputation also applies to the field of electric vehicles (EVs).
As clean energies go, comparatively unglamorous natural gas doesn’t get the attention of its flashier cohorts, but a new project in Leesburg, Va., may soon be one of the cleanest and most efficient sources of electricity generation in the country.
Evaluating the cost- effectiveness of renewable power has always been a fairly simple calculation. As manufacturers lowered their production costs and improved the generating efficiency of their technology, renewables became more cost competitive with conventional sources of power.
Mobile lighting systems powered by hydrogen fuel cells are cleaner and quieter and now have a proven track-record in applications like nighttime construction, sports and entertainment events, and airport operations, making them ready for commercialization and broader use.
