Industry Focus: When Electronics Go Green, Everybody Wins

December 4, 2008 11:45 am | by Jeff Ittel, senior vice president of semiconductors, Avnet Electronics Marketing | Articles | Comments

For members of the electronics supply chain, going “green” is not just a short-term marketing scheme rife with buzzwords but short on substance. Granted, the tech sector has jumped on its share of bandwagons, but this movement is different. It’s not just about pioneering technologies, building a positive public image, padding the bottom line or even “doing the right thing.” It’s all of the above. When state-of-the-art electronic products are energy efficient, environmentally sustainable, and cost effective, everyone wins.

Wind Turbine Design Reduces Blade Size, Saves Money

December 3, 2008 11:10 am | by by Jason Lomberg, Technical Editor | Blogs | Comments

Betz’ Law (culled from its namesake, Albert Betz) is a theory for flow machines. From this theory we derive the Betz Limit, that is, “the maximum possible energythat may be derived by means of an infinitely thin rotor from a fluid flowing at a certain speed.” In windmills, this equates to how much electricity can be harvested from the wind energy. Current technology allows turbines to capture a maximum of 59 percent of the energy in wind
