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?
Washington Gov. Chris Gregoire signed legislation to phase out coal-fired energy production at the TransAlta power plant in Centralia, Wash. Senate Bill 5769 solidifies into law a collaborative agreement to close the state’s two coal boilers.
A new design for thin-film solar cells that requires significantly less silicon and may boost the efficiency is the result of an industry/academia collaboration between Oerlikon Solar in Switzerland and the Institute of Physics’ photovoltaic group at the Academy of Sciences of the Czech Republic.
As if being an Internet giant is not enough, Google, the Mountain View, Calif.-based search engine company, is on to renewable power. In the span of little more than a decade, Google has transformed itself from garage start-up to an international corporation.
In the Herculean effort to wean the nation off fossil fuels, energy efficiency and renewable power share a common obstacle: cost. Despite growing national awareness and popular support, their prohibitive price tags prevent most American homeowners from making an upgrade.
Light has both electric and magnetic effects, but until a recent discovery by physicists at the University of Michigan (UM), scientists believed the magnetic properties of light were so weak that it would be useless for practical applications.
Despite recent reports of coal-fired power plants shutting down and states moving away from coal as a generation source, it seems the nation’s dominant source of fuel for generating electricity will be around for years to come.
Schneider Electric announced the upcoming launch of its EcoXpert program, intended to train electrical contractors in installing and implementing energy efficiency and renewable-energy products and solutions.
