The wind energy business is beginning to look as frenetic as the merchant gas-fired power business in the late 1990s—with some critical differences. If the 10 issues listed here are addressed soon, wind power may avoid a crash and burn similar to the one that beset the gas turbine business.

In chemistry, osmosis refers to the movement of water molecules through a selective membrane from an area of low solute concentration to an area of high solute concentration, creating a pressure gradient. Researchers have recently demonstrated that exploiting this natural phenomenon could produce useful amounts of electrical power.

IT project engineering skills aren’t taught in college; they’re developed through on-the-job training with seasoned mentors. Begin honing your project management skills by firmly grasping the fundamentals presented in this article.

Harvard Business School Professor Clayton Christensen coined the term "disruptive technology" in his best-selling 1997 book, The Innovator’s Dilemma. According to Christensen, a disruptive technology unseats a dominant technology by creating products that are so much cheaper or better in one or more ways that they quickly become the new mainstream standard, transforming an entire […]

The U.S. electric utility industry has long encouraged its customers to get more value from their electricity dollar. Today, the industry—facing volatile costs and mounting concerns about the environment—is coming together to create a new role for energy efficiency—one that enables technology to deliver more value to customers and electric utilities alike. For example, "smart" […]

The visible consequences of sulfuric acid aerosol emissions—opaque stack emissions called “blue plumes”—are merely the tip of an iceberg. In sufficient concentration, SO3 also can increase corrosion and fouling of equipment and components downstream of the furnace while decreasing their efficiency and penalizing overall plant heat rate.

More top utilities are making plans to add one or more integrated gasification combined-cycle (IGCC) plants to their generation portfolios over the next decade. Some 25 separate projects are on the drawing board, virtually all planning to use Eastern coal. Western coals pose tougher challenges for gasifiers, and their lower heat content disadvantages project economics. […]
