- Opinion
  - Economy TrumpsClimate Change
    Meaningful climate change legislation in the U.S. Congress seems unlikely any time soon.
- View on Renewables
  - Durability & Reliability Challenges for Photovoltaics
    The increase in activity in the clean energy sector leads one to believe that this time around the excitement may actually amount to something.
- Nuclear Reactions
  - Principles Before Plan
    During the presidential campaign much was made of the differences between Senators Obama and McCain in terms of their support for nuclear power.
- POWER-GEN @ 20
  - POWER-GEN International @ 20:A Look Back at Issues and Events from 1988
    Twenty years ago on page 6 of the January 1988 edition of Power Engineering magazine, a full-page ad introduced “POWER-GEN ’88” to the world.
- Startup
  - 20th Annual POWER-GEN International
    Here’s a guide to making the most of your time at POWER-GEN International and NUCLEAR POWER International.
- Field Notes
  - Instrument Mounting and Manifold System
    A new type of mounting system for process transmitters is helping to improve control system maintenance at Athens Generating Plant’s combined-cycle power generation facility in Athens, N.Y.

  - Wyoming Energy Efficiency: Up the Road a Piece?
    Seems that Wyoming ranks dead last on the American Council for an Energy-Efficient Economy’s 2008 “State Energy Efficiency Scorecard.
Features
- Turbine Tech Drives Wind Into the Generation Mainstream
  From the first megawatt-size wind turbine erected in the U.S. in 1941 to the sleek and powerful designs of today, technological advancements have steadily upgraded wind energy’s position in the generation mix so that now, it’s right in the mainstream.
- Substratum Intake System: Once-Through Cooling Hybrid
  Rising fuel cost, demand for carbon footprint reduction and closed-cycle cooling is simply incongruent.
- Supplemental Pumps Pay Off During Low River Conditions
  Low river levels are causing reliability problems with once-through circulating water pump systems at several coal-fired power generating plants sited along the Missouri and Mississippi rivers.
- Steam Generation Thermodynamics 101
  Everyone knows baby boomers in the power sector have reached retirement age, meaning many new hires will be thrust into technical positions where fundamental information is valuable.
- Define Then Achieve Fleet Optimization
  The term “optimization” has been used so much, for so many things, that by now it has almost no meaning.
- Coordinated Control and Optimization of a Complex Industrial Power Plant
  Alcoa World Alumina L.L.C. is one of the world’s largest producers of metallurgical grade alumina, the raw material for the aluminum smelting process.
- Interim Tier 4 Emissions Regulations for Generators
  Keeping apprised of the U.S. Environmental Protection Agency’s (EPA’s) complex diesel emissions regulations can be a challenge, but now that these requirements encompass not only mobile off-highway applications but also stationary applications, it’s up to the generator owner/operator to stay informed.
- Ultra-Low NO_X Burners Can Get Even Better
  In the mid-1990s, a technology was developed that allowed burning natural gas in industrial boilers while producing nitrogen oxide (NO_X) emissions less than nine parts per million by volume (ppm).
- Designed-in Safety
  As design engineers and architects, we have a tremendous opportunity to improve the quality of life in the communities in which we work and live.
- Heat Exchanger Technology: The Advantages
  For many of the new European supercritical coal-fired plants, builders are turning their attention to a heat exchanger technology that offers convincing technical and economic advantages over conventional U-type feedwater heaters.
- Oil-Filled Transformer Explosions
  Power transformers are one of the most dangerous pieces of electrical equipment because of the large quantity of oil they contain, which is in direct contact with high voltage elements.
- The Case for Using Reclaimed Water
  If climate change is found to have significant impacts, one area may be in how precipitation changes will affect how much water is available for power production.
- Sonic Horns: A User’s Introduction
  A sonic horn can get material flowing in your storage vessel or hopper truck or railcar by directing low-frequency sound vibrations into the vessel to fluidize stagnant material and buildup.
- SCADA Systems: Unknown Connections Could Spell Trouble
  The ease with which TCP/IP enables one to connect networks has been a huge boon for the power generation industry.
