  • Battle of the Bulb

    When then-President George W. Bush signed the Energy Independence and Security Act of 2007, he noted that, “New technologies will help usher in a better quality of life for our citizens.” One provision of the act required an increase in the efficiency of newly manufactured lightbulbs, starting with 100-watt incandescent bulbs in 2012.

  • Specifying Nuclear DCS Power Supplies

    The consideration of power supplies has become critical to the success of converting analog instrumentation and control systems to digital control systems (DCSs). Careful planning is particularly necessary for nuclear power plants, where instrumentation systems are required for safely shutting down a reactor, mitigating the consequences of an accident, and performing post-accident analysis.

  • The Big Picture: DOE Loan Guarantees

    Of the $35.9 billion in loan guarantees awarded by the U.S. Department of Energy (DOE) since 2009, roughly $26.5 billion have financed nuclear and renewable power projects across the nation through the Section 1703 and 1705 loan guarantee programs.

  • Abundant Clean Energy Fuels Brazil’s Growth

    Brazil’s power industry has long been dominated by its vast hydro resources, which historically have accounted for over 80% of the country’s generation capacity. With engineering marvels like the massive Itaipú dam and the proposed Belo Monte project, the country is a leader in the development and use of hydroelectricity on a grand scale. But as the 2001 energy crisis proved, dependence on a single source leaves the country vulnerable to severe shortages. Thanks to government programs designed to take advantage of the country’s favorable climate, Brazil is committed to diversifying its energy mix while continuing to maintain a renewable energy focus.

  • European Firms Complete Wind-to-Hydrogen Power Plant

    A consortium of European developers, with funding from the German federal government, have completed a power plant in Prenzlau, near Berlin, Germany, that uses excess wind energy to convert water into oxygen and hydrogen in a process called hydrolysis, and then uses hydrogen and biogas to generate power and heat.

  • Colstrip’s Cure for Mercury

    In January 2012 a new mercury control system at the Colstrip power plant in Montana reached its first major milestone: two years of operation with mercury emissions below the state regulatory limit.

  • Avoiding Flow-Induced Sympathetic Vibration in Control Valves

    Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work. Determining the design changes required in the valve and fluid system to prevent the vibration from occurring requires advanced analytical techniques.

  • Environmental Rules Prompt Closure of More Coal Plants, Pause Development of New Plant

    Citing newly finalized and proposed environmental regulations that could make costs uncertain, FirstEnergy Corp. on Thursday said it would shutter six older coal-fired power plants with capacities totaling 2,689 MW in Ohio, Pennsylvania, and Maryland by September. The same uncertainties prompted a major backer of a $2 billion coal-fired power plant planned for Washington County in Georgia to pull its funding.
