The Growing Role of Waste-to-Energy in the U.S.

Using nonhazardous waste for power generation is a trend that’s gaining steam for several reasons. Though there are several environmental reasons, another is the reliability of the fuel supply.

Recession Reduces Demand for Electricity

When roving Contributing Editor Mark Axford attended several recent energy conferences, he found the same questions asked at each one about new U.S. generation sources and consumption patterns. Unfortunately, the experts had few good answers to those questions.

Computer Simulation of HRSGs Can Improve O&M

Obtaining accurate data about the performance of a plant’s heat-recovery steam generator is crucial to ensuring the smooth operation and maintenance of the equipment. Software designed to model and simulate HRSG operations can provide valuable information about corrosion and other operational problems.

Turkey Opens Electricity Markets as Demand Grows

Turkey’s growing power market has attracted investors and project developers for over a decade, yet their plans have been dashed by unexpected political or financial crises or, worse, obstructed by a lengthy bureaucratic approval process. Now, with a more transparent retail electricity market, government regulators and investors are bullish on Turkey. Is Turkey ready to turn the power on?

CHP: Helping to Promote Sustainable Energy

Because combined heat and power (CHP) plants optimize energy use, they cut fuel costs and pollution. Even though U.S. power plants have been using CHP for decades, today’s energy experts have a newfound appreciation for its ability to promote sustainable energy use.

Energy R&D: The Missing Link to a Sustainable Energy Future

Q: What do you get when you gather roughly two dozen top researchers from academia, government, and industry to speak on interdisciplinary energy-related issues for a week?
A: A lot of informative but crowded slides, high-octane brain power, fact-based analysis of where we are and we’re headed globally, informed questions, and surprisingly practical answers.

Gone with the Wind

Secretary of the Interior Ken Salazar, speaking in Atlantic City on April 6, added more hot air to the discussion about offshore wind when he stated that windmills off the East Coast could generate enough electricity to replace most, if not all, of the coal-fired power plants in the U.S. I’m disappointed Salazar didn’t take a few minutes for fact-checking and back-of-the-envelope ciphering before his speech.

Canada Moves to Rebalance Its Energy Portfolio

Though Canada is rich in fossil fuels, nuclear power may fuel a significant portion of the nation’s future electrical generation needs, especially in provinces that have traditionally relied on hydropower and fossil fuels.

Major Advancements for Polymer Solar Cell Technology

Denmark’s Risø DTU National Laboratory for Sustainable Energy in late April announced it had connected the world’s first polymer solar cell plant to the grid. The achievement follows years of research into the novel photovoltaic (PV) technology that has been touted as a future inexpensive, flexible, and customizable alternative to silicon crystal solar cells. The […]
