  • Avoiding Wildlife Impacts from Renewable Energy in Europe

    Courtesy: Ad Meskens/Wikimedia Commons Europe has been in the forefront of renewable energy development, and though the scientific research on wildlife impacts is limited, European environmentalists and developers are beginning to create baseline frameworks and guidelines. Developers around the world can learn from their experience. As more renewable energy systems come online, providers hope to […]

  • Weighing the Environmental Impacts of Wind and Solar

    Renewable generation is usually characterized as more environmentally friendly than fossil fuels, and in many respects, that’s true. But there is a growing recognition that solar and wind generation have their own impacts, and an increasing number of manufacturers and generators are looking for ways to minimize them. Iceland might be about the last place […]

  • PRB Coal Users’ Group Plant of the Year: Ameren’s Rush Island Energy Center

  • China’s Coal Industry: Status and Outlook

    The years between 2002 and 2012 are called Golden Decade for the coal industry in China. After May 2012, the coal industry fell into depression. In the Golden Decade, a large amount of social capital inflow

  • Energy from Waste: Greenhouse Gas Winner or Pollution Loser?

    Is waste-to-energy the best greenhouse gas fighter among electric generating technologies? Or do trash burners spew dangerous air emissions? The answer may be a surprise. What electricity-generating technology results in net greenhouse gas (GHG) reductions, not just zero new emissions? According to the U.S. Environmental Protection Agency (EPA), it’s not nuclear, not wind, not solar. […]

  • Generators Grapple with ELG Implementation

    Plant wastewater treatment is not what it once was, and changes in the Environmental Protection Agency’s effluent limitations guidelines (ELG) have added a host of new wrinkles. A panel of power plant experts discussed what plant managers are planning and doing to keep things running smoothly within the new rules. For more than three decades, […]

  • Understanding and Mitigating Metallurgical Effects of Coal Blending and Switching

    Fuel blending and switching has become the norm in response to regulatory and market forces, but many older boilers were designed for a particular fuel. Understanding the effects of different fuels on

  • World Nuclear Exhibition Addresses Challenging Markets and New Solutions

    The second World Nuclear Exhibition (WNE) began on June 28 in Le Bourget, just outside Paris, with the usual mixed messages about the need for and challenges of nuclear power globally.
