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.
The devastating March earthquake and tsunami in Japan caused a meltdown at the country’s Fukushima Dai-ichi nuclear plant, and triggered the latest cycle of drama in the ongoing and tumultuous affair with nuclear power.
All the policies, rhetoric and tax incentives may be finally starting to pay off. New statistics reveal that wind power and other renewables are showing sustained and consistent growth, a sign that they may have reached a new stage of maturity in the American energy market.
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.
