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.
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
The ongoing energy-efficiency work at the Empire State Building has achieved another milestone on its journey toward sustainability leadership in the commercial real estate community by receiving its second Energy Star certification from the U.S. Environmental Protection Agency.
Although the worldwide economy continued to sputter in 2010, there was at least one bright spot on the global stage. According to a recent study, renewable power showed its perseverance last year, fighting off headwinds and gaining traction.
It’s hard to imagine where technological innovation will go next, with so much inventive ground already covered, if not trampled. A recent announcement indicates there is still plenty of room for groundbreaking change, especially when it comes to wireless devices.
In the ambitious task of retrofitting existing structures with the latest energy-saving technologies, one critical area is the nation’s aging stock of affordable housing. One of the biggest obstacles to making the needed improvements is the lack of adequate financing.
In late July, utilities across the country issued notices to their customers, pleading with them to minimize energy use during the projected heat wave—a prolonged period in which every state in the country broke heat records.
It’s a generally accepted belief that people tend to be wary of things that are unfamiliar to them, so it would make sense this behavior would extend to the smart grid and smart meters, a relatively new trend in an industry on which most consumers are not educated.
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.
