Electric Sand Findings Could Lead To Better Climate Models

E-mail Print PDF
Image[bkeps.com]Wind isn't acting alone in the geological process behind erosion, sand dunes and airborne dust particles called aerosols. The other culprit is electricity. By taking both factors into account, researchers at the University of Michigan have developed a new model that matches real-world measurements of "saltation" better than the decades-old classical theory.

Wind Power Explored Off California's Coast

E-mail Print PDF
Image[bkeps.com]In many ways, wind energy seems an ideal energy source. Fields of mighty turbines spinning in rhythm could harness carbonless power and shuttle it off to homes and industries. But questions remain about the feasibility of wind parks: How much will they cost? Can this unpredictable energy source be relied upon to contribute appreciably to the country's power needs?

Dealing With Wind Variability On The Wind Farm

E-mail Print PDF
ImageAs Texas’ electric grid operator prepares to add power lines for carrying future wind-generated energy, an electrical engineer at The University of Texas at Austin is developing improved methods for determining the extent to which power from a wind farm can displace a conventional power plant, and how best to regulate varying wind power.
