Many measures gauge the progress of renewables’ ongoing quest to become a mainstream source of power. Among them is the race to surpass traditional sources for share of total energy production. In this regard, renewables have made great strides.
A retail chain known for its friendly greeters and low prices has taken a bold step to reduce the cost of powering its famously large stores. Retail giant Walmart has announced that 130 of its stores in California will be powered by the sun by the year 2013.
James Strange III, vice president of Louisville, Ky.-based Advanced Electrical Systems Inc., first began thinking about adding electric vehicle (EV) chargers to his company’s installation services at last year’s NECA Show.
The evolution of Basic tool types occurs slowly (think screwdrivers and measuring tapes). Then there are times when a new tool technology (or the advancement of an old approach) rapidly changes a market segment (e.g., lithium-ion batteries for professional hand tools).
It’s the nature of technology to continually break new ground. As one innovation catches on, another follows closely on its heels. For example, just as the smart grid is gaining traction, another new form of smart technology is poised for a breakthrough of its own.
The way some people tell it, a dramatic decline in construction fatalities can be attributed to only one thing: high unemployment and a decrease in building activity during the economic downturn, resulting in fewer people being exposed to hazards on construction sites. Those people are wrong.
Lighting represents a substantial portion of the annual energy use and expense of any commercial building despite building owner and occupant energy -conservation and efficiency efforts. According to the U.S.
Tornadoes, earthquakes, hurricanes, unprecedented rainfalls and record-high 500-year flooding levels in 2011 have all together caused massive damage to the grid, homes, businesses and public infrastructure and billions in damage costs.
In the first quarter of next year, SAE International plans to establish a standard, integrated coupler that would allow electric vehicles and plug-in hybrid electric vehicles to be charged from either a conventional, 15-amp alternating current (AC) wall outlet or a direct current (DC) connector of
Some things in education remain the same--—it’s all still really about reading, writing and arithmetic. But the way those and other subjects are taught has evolved significantly since many of us spent time in a classroom.
In the never-ending quest to find new, more energy-efficient lighting technologies, light-emitting diodes (LEDs) have always held great promise. Like so many other technologies with great potential, making them cost-competitive has been the challenge.
From microwave ovens to Humvees, the military has a long history of developing and fine-tuning new technologies that later become accessible to the general public. To be sure, some have flopped while others have become household necessities.
In the quest for more widespread adoption of energy-efficiency measures, cost is one of the biggest challenges, as it is for so many of the new technologies considered integral to green building. However, in one state, officials may have found a solution.
Once only a luxury item for the wealthy, home automation technology that integrates a house’s electrical and low-voltage devices is becoming more commonplace in U.S. residences. Previously, its adoption was sluggish because of the installation complexity and high cost.
Sometimes, big change comes in small steps. For example, consumers have long since bought, literally and figuratively, into the notion that they can do their part to save energy by making seemingly innocuous changes to their daily lives, such as purchasing only compact fluorescent lamps (CFLs).
Black & Veatch, a consultancy company, evaluated a one-year smart meter pilot program for ComEd, the Chicago-area utility. They found customers of the utility could save $2.8 billion on their electric bills over the 20-year life of a smart meter.
