As the use of renewable power, electric vehicles (EVs) and the smart grid become more widespread and integrated, one challenge also becomes more apparent: storage. Thankfully, the experts are on it. This summer, the U.S.
Fuel cells are an evolving technology and a current new market for the electrical contractor (EC). As a result of research and development, fuel cells have become feasible to implement with greater capacity, reduced costs, increased reliability and improved efficiency.
Renewable power has the potential to transform our energy consumption, but like most innovations, it has a downside. One of the biggest stumbling blocks to a renewable-powered society is the intermittent nature of its generation.
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.
Fuel cells may not be commonplace, but they are more commercially available than ever before. Their burgeoning success in providing power can be found in standby, prime and distributed generation mobile and vehicle applications.
From the Gulf Coast to the Eastern Seaboard coastline, experts remind us of the annual threats from the hurricanes. The headlines scream, “Prepare for the storm.” We scrutinized numerous checklists on important steps to protect your home, family, and business in the event of a natural disaster.
While preparing a presentation, I noticed a photo taken at a facility where temporary power was needed periodically. The facility rented a generator when necessary. It showed a disconnecting means with four individual conductors stubbed out of the bottom of the enclosure.
Reliability of backup power systems, called uninterruptible power supplies (UPS), hinges on proper installation, regular preventative maintenance and well-being checks. Without them, you may as well start working on your resume.
According to USA Today, a new type of sodium-sulfur-based (NaS) battery is looking to revolutionize the world of power storage. These batteries have a life span of about 15 years and take up only a fraction of the space used by traditional lead-acid batteries.
Bernard Malin of Massachusetts is the owner of a residential “micro combined-heat-and-power” (micro-CHP) system, according to the Christian Science Monitor; the device combines an internal-combustion engine with a household natural gas furnace, and Malin saves about $600 to $800 in electricity costs
At a recent National Electrical Code taskforce meeting dealing with mission-critical facilities relative to scenarios proposed by the Department of Homeland Security, the main concern seemed to be “you can’t test critical facilities.
An energy transition with the potential to revolutionize the country's infrastructure is gaining momentum. It is not brokered through expanded power grids or traditional fossil-based economics-it is powered through fuel cells. Fuel cell development is on the upswing.
Manufacturers of standby power generators aren't sitting back and waiting for someone else to reinvent the market-they're doing it themselves. Don't think of backup power generators as noisy, chugging units that struggle into operation.
As the Great Blackout of 2003 rolled through the Northeast and Midwest, a lot of people were left in the dark. But the blackout turned on the lights for a group of National Electrical Contractor Association (NECA) member contractors in Michigan. They saw the blackout as opportunity knocking.
Last year's blackout sparked a sharp rise in consumer interest in ensuring constant uptime, which has provided more and more opportunities for the electrical contractor. With this increased demand comes the consumer's desire for more cost-effective power.
