Second Wind’s Triton Sonic Wind Profiler, a ground-based remote sensing system used to measure the wind at the heights of commercial turbines, was confirmed as a valid stand-alone system for wind resource assessment by an Energy Research Center / Netherlands (ECN) study.
Eurus Energy America Corporation has completed its second wind farm in the State of Oregon. Construction on the 63-megawatt (MW) was completed in late December 2009 with energy sales commencing on January 1, 2010 under a 20-year power purchase agreement with Clark County’s Public Utility District Number 1.
One of the world’s leading renewable energy publications has recognized Massachusetts-based Second Wind Inc. as a finalist in its first-ever Excellence in Renewable Energy Awards. Second Wind, a leading provider of wind information technology, was named a finalist last week by RenewableEnergyWorld.com in the category of Innovation in Renewable Energy for its game-changing Triton Wind Profiler.
National Wind Assessments, a team of independent wind consultants, has adopted Second Wind’s Triton Sonic Wind Profiler to add value to its wind resource assessment offerings.

The following was posted yesterday in response to a letter in the [i]Casper (Wyo.) Star-Tribune[/i] talking about wind’s “intermittency” and wondering how much net energy a wind turbine produces:
[quote]Wind is actually more variable than “intermittent”–a typical wind farm will generate some electricity 65% to 90% of the time, depending on the wind speed patterns. Much of the time, it will be generating at less than full capacity, which is why its “capacity factor” (its average generation divided by its full capacity) is more like 40% at the best sites.
Second, wind has a rapid “energy payback”–something that has been documented by numerous studies in the U.S. and elsewhere dating back to the 1980s. A wind turbine typically takes only a few months (3-8, depending on the average wind speed at its site) to “pay back” the energy needed for its fabrication, installation, operation, and retirement.[/quote]
