The traditional method of thinking in nanoscale materials is that smaller is better, but researchers at the University of Maryland’s A. James Clark School of Engineering are challenging traditional thermoelectric theory.
With no shortage of sunlight, solar power is an attractive option in Florida. To help ramp up the appeal, the state’s largest electric utility has thrown in some generous financial incentives. This summer, Florida Power & Light Co.
The U.S. Consumer Product Safety Commission (CPSC) urged residents in the Atlanta area to check their homes for counterfeit smoke alarms. About 18,500 such alarms were distributed for free between 2006 through May 2011 as part of the Atlanta Smoke Alarm Program.
Risk is a part of life, but it’s more immediate and apparent in some lives—including those spent in the construction industry. Every construction project starts with some uncertainties. Will anything prevent us from accomplishing what we promised? Will we make a reasonable profit?
By adding the right amount of heat, researchers have developed a method that improves the electrical capacity and recharging lifetime of sodium-ion rechargeable batteries, which could be a cheaper alternative for large-scale uses, such as storing energy on the electrical grid.
Lighting evolves based on need. Incandescent made way for brighter fluorescent. Fluorescent made room for solid-state lighting (SSL). The next big idea may be light-emitting diodes (LEDs). While they are an SSL source, LEDs are new to general lighting applications.
Any given year has its predictions. If you’re reading this article, the world as we knew/know it didn’t end on May 21—one of the most publicized predictions for 2011. In Chicago, Cubs fans may yet again be asserting that next year will be the year their team goes all the way.
As cars become more energy- and emissions-efficient, so are the factories that make them. General Motors recently announced two such projects that will bring renewable energy and more sustainable operation to its Michigan automobile assembly plants.
Debate continues about whether LEDs have the output in lumens, the color consistency and the price point to replace traditional incandescent, halogen and fluorescent lamps in high brightness and general illumination applications. Is it finally time to end the discussion?
Within the next decade, building operators and homeowners will more effectively optimize their energy consumption and resources in collaboration with their utilities to meet more than 20 percent of electrical demand in the United States.
The LED revolution continues to promise many lighting benefits, such as compact size, energy efficiency, long service life with long mean time between failures, no mercury disposal, a resistance to shock and vibration, and no radiated heat or UV output.
Clean Edge released its second annual U.S. Clean Energy Leadership Index. The index provides an analysis and ranking of how all 50 states, and the individuals, businesses, and organizations that operate there, compare across the clean-energy spectrum.
It’s not often that an electrical contractor has the opportunity to sell a product line that saves a customer time, money and energy; promotes green sustainability; and reduces the load on the nation’s power grid. But that’s what industry observers say LED lighting sources can do.
