Was sind intelligente Netze? In Diskussionen tauchen immer wieder verschiedene Vorstellungen über intelligente Stromnetze auf. Was verbirgt sich hinter dem Smart-Grid oder den intelligenten Netzen?

Während es für Gold, Silber und Kupfer bereits erprobte Recyclingverfahren gibt, werden die für die Hochtechnologie wichtigen Seltenen Erden wie Palladium und Indium bislang nicht nennenswert wiederverwertet. Deren Recycling ist zwar technisch möglich, wurde aber wirtschaftlich zumindest bislang nicht für sinnvoll erachtet. Angesichts steigender Preise für Edelmetalle und Seltene Erden sollte man jedoch annehmen, dass auch die Wiederverwertung der Altgeräte zunehmend interessanter und die Goldmine in der Abstellkammer erschlossen wird.

why smart homes are not fit for mass market smart installations are 400% more expensive than conventional ones additional cabling complicates reconstruction 75% of the investment are labor costs high maintenance costs 1 node costs about 3W = 26 KWh/a = ca 4 €/a

In Cradle to Cradle, McDonough and Braungart argue that the conflict between industry and the environment is not an indictment of commerce but an outgrowth of purely opportunistic design. The design of products and manufacturing systems growing out of the Industrial Revolution reflected the spirit of the day-and yielded a host of unintended yet tragic consequences. Today, with our growing knowledge of the living earth, design can reflect a new spirit. In fact, the authors write, when designers employ the intelligence of natural systems—the effectiveness of nutrient cycling, the abundance of the sun's energy—they can create products, industrial systems, buildings, even regional plans that allow nature and commerce to fruitfully co-exist. Cradle to Cradle maps the lineaments of McDonough and Braungart's new design paradigm, offering practical steps on how to innovate within today's economic environment. Part social history, part green business primer, part design manual, the book makes plain that the re-invention of human industry is not only within our grasp, it is our best hope for a future of sustaining prosperity.

"This is an incredibly naive article on renewable energy. Ms Eilperin makes the ridiculous assumption that nat gas will be the panacea to all our energy problems.  Anyone familiar with the electric utility industry, knows that their pricing is slanted to their favor."

Trifft es ziemlich gut, den !Green Backlash muss es dennoch zwingend geben bevor es wieder besser werden kann
