While experimenting with high-frequency current, inventor Nikola Tesla developed an electrodeless lamp, but the concept remained largely unexplored for the next century (except as a novelty lamp in the 1980s).
In the ongoing pursuit of a more sustainable energy future, the efficient use of power in existing buildings is taking on an ever-expanding role. The White House recognizes this growing movement and has invested a healthy amount of federal dollars into it.
The renewable-power industry is one of the greatest showcases of human innovation and ingenuity, drawing energy from sources that are clean, free and infinite. It also seems to possess a flair for the dramatic.
The nation’s largest hydroelectric facility is about to get an upgrade. As its 75th anniversary approaches, aging transmission lines at Washington’s Grand Coulee Dam will be removed and replaced with safer, more reliable lines.
As the renewable power revolution carries on, wind power continues to lead the way. According to the American Wind Energy Association (AWEA), the trade association for the U.S. wind energy industry, 2011 was a year of many milestones, and 2012 promises more of the same.
Construction employment increased in December by 17,000, driven by gains in nonresidential construction employment, according to an Associated General Contractors of America (AGC) analysis of new federal employment data.
California has long been a pioneer in renewable technologies, in particular, solar power. But blazing a trail and staying on it are two different things. In this case, the Golden State has managed to succeed at both.
As the popularity of electric vehicles (EVs) begins to grow, so will the opportunities for electrical contractors. In fact, the two are a natural pairing. Both rely on a steady current of electricity. Without it, they can’t work.
As the world embraces mobile technology, so does its work force, and it makes sense that businesses would want to embrace mobile, too. According to a recent poll, that is exactly what they are going to do.
It would be nice to think that, with all of the collective expertise and creativity of engineers and architects, most of the problems related to energy efficiency in buildings could be resolved in the design and build phases. Sadly, that is not the case.
Energy projects currently underway across the United states reflect several trends—new construction in the alternative-energy sector and renovation at traditional power plants to update aging infrastructure.
The Solar Foundation, a nonprofit solar education and research organization, released its second annual review, “National Solar Jobs Census 2011: A Review of the U.S. Solar Workforce.” The report found that hiring in the solar work force is on the rise.
Being able to predict what to expect from the Occupational Safety and Health Administration (OSHA) in any given year varies from a crystal ball divination to a precise calculation. Changing administrations and a lack of performance history leave much to the imagination.
MISO, a regional transmission organization, approved its Transmission Expansion Plan 2011 (MTEP11), a comprehensive, long-term regional plan for the electric grid that will bring more than $2 billion in annual benefits for decades to come for energy consumers throughout the Midwest.
It’s not often in the United States that something can generate widespread, near unanimous support, and even less likely for it to completely ignore political party lines. According to a recent poll, solar power is currently enjoying that kind of popular appeal.
By now, the electrical industry is well aware that national energy standards have eliminated the manufacture and import of fluorescent magnetic ballasts for 4- and 8-foot standard and energy-saving T12 lamps, with few exceptions.
