  • It’s Time to Go Nuclear

    Congress should push for nuclear energy as a climate and energy solution—now.

  • Top Plants: Portlands Energy Centre, Ontario, Canada

    Construction of the Portlands Energy Centre was a logistical dream: A mothballed power plant next door had an active switchyard, natural gas pipeline, and cooling water structure. The new facility put peak power into the Ontario Power Authority’s grid from its two combustion turbines only two years after collecting the necessary permits. The entire plant entered commercial service on April 23, 2009 — six weeks early.

  • Nuclear Developments in Europe

    Recent months brought several developments in Europe’s much-touted "nuclear renaissance." Spain Extends Life of Nation’s Oldest Reactor Spain’s government on July 2 granted a four-year extension to the operating permit of the 466-MW Santa María de Garoña nuclear power plant (Figure 3). The decision follows a nonbinding recommendation by Spain’s nuclear regulator in June to […]

  • Green Power? The Limits of Cellulosic Biofuels

    There’s been a lot of attention on “cellulosic” ethanol, but that could be a nasty dead end, according to this analysis from a well-respected Washington environmental think tank.

  • Top Plants: Riverside Repowering Project, Minneapolis, Minnesota

    Xcel Energy has completed the third and final project required by its 2003 Metropolitan Emissions Reduction Project agreement: repowering the Riverside Plant with a gas-fired 2 x 1 combined-cycle plant and tearing down the old coal-fired plant. Saved from demolition was the Unit 7 steam turbine system that now serves the new plant. Xcel staff expertly managed the project to an on-time start-up and accepted many important construction tasks, harkening back to the days when utilities took a more active role in the design and construction of projects.

  • Swiss Solar Plane Prototype Designed to Fly Day and Night

    The first aircraft designed to fly day and night propelled solely by solar energy was unveiled at Dübendorf airfield, Switzerland, in late June. The Solar Impulse has the wingspan of a Boeing 747-400 and the weight of an average family car (1,600 kg) (Figure 4). More than 12,000 solar cells mounted onto the wings will […]

  • TREND: Wind Power Becalmed?

    U.S. wind power appears becalmed, partially stymied by transmission constraints, and also by financing difficulties in the current recession. Read the details.

  • Top Plants: Royal Pride Holland Commercial Greenhouse Cogeneration Plant, Middenmeer, North Holland Province, Netherlands

    At Royal Pride Holland’s commercial tomato greenhouse, green thumbs and green energy go hand in hand. With a total energy utilization of 95% in this application, GE’s new Jenbacher J624 natural gas – fired engines offer the innovative greenhouse an economical supply of on-site electrical and thermal power, as well as CO2 fertilization, to support its operations.

  • Scotland Officially Opens 100-MW Glendoe Hydro Plant

    In late June, Scotland officially opened the Glendoe Hydro Scheme, a 100-MW project whose construction near Loch Ness in the Scottish Highlands was the region’s biggest civil engineering project in recent times. Planning for the project began in 2001, and it took three years to build. Today, the project has the highest head — the […]
