Wind Power Projection Dependent On Improved Energy Storage Technology

Posted by John O'Connor on Jul 20, 2011 2:59:00 PM
wind power projectionLong believed by many to be one of the "purer" sources of alternative energy, any wind power projection has noted the rapid growth in the industry during recent years.  The World Wind Energy Association calculates that electricity from wind accounted for 2.5% of worldwide consumption in 2010 at 430 TWh, and that this output doubled what was available only three years earlier.  Many European nations, such as Spain and Denmark have begun intensive investments in wind energy and Germany is expected to be a major player following the forecasted shutdown of the nation's nuclear industry.  Outside of Europe, China has aggressively pushed wind energy in Asia and currently has the world's largest installed wind power capacity at almost 42,000 MW.

Alternative Energy Distribution Methods

Posted by Dave Zendzian on Jul 12, 2011 11:11:00 AM

The term alternative energy generally describes renewable sources such as solar, wind, and hydroelectric power. Hydroelectric energy accounts for the majority of U.S. renewable energy, at 70 percent, though the use of solar, wind and other renewable energy is continuing to grow. Methods of alternative energy distribution vary, and here I’ll provide a brief description of the three most prevalent methods. It’s important to keep in mind that digitally controlled power systems will help prevent wasted energy, no matter which distribution system is used.

Active Front-end or Grid Tie Inverter?

Posted by John O'Connor on Jan 27, 2011 5:58:00 PM

We have the habit here at Oztek of using the term "active front-end" (AFE) and grid tie inverter (GTI) interchangeably.  On more than one occasion discussing our grid tie inverter controller, I’ve caught myself somewhere mid-conversation inadvertently switch to using the term active front-end.  It's of no concern internally, but quite frequently its cause for confusion when speaking with customers.  Earlier this week I received a call from a customer that was pretty certain an AFE would not work in his GTI application.  This got me thinking, "What exactly is the difference between an active front-end and a grid tie inverter?"
