We've done a number of energy-efficiency projects at our house over the last year. While it may help us lowering our own energy costs and usage, it'd be naive to think that it'll decrease overall energy consumption.  Harry Saunders has done the research to explain this effect, know as "the rebound effect".

Varying degrees of rebound occur because the phenomenon works in several ways. Increasingly efficient technologies effectively lower the cost of energy, as well as the products and services in which it is embedded. This results in firms consuming more energy relative to other production inputs and producing more output profitably. Firms and individuals benefit from cheaper and more abundant products and services, causing them to find many more uses for these (and the energy they contain). A more efficient steel plant, for example, produces cheaper steel that, in turn, allows firms and individuals to afford to find more uses for the same material.

Why Energy Efficiency Does not Decrease Energy Consumption

More amusement from Craiglist job postings. Hmm, which of these technologies could you seriously have 10 to 15 years of experience with?  Fifteen years ago, I was still an undergraduate in college, Amazon did not exists, and EC2/AWS certainly didn't and  Java was still a wanna-be Flash plugin for your Browser.

The ideal candidate will have 10 to 15 years of relevant work experience using the following: 

• Java 2 Enterprise Edition (J2EE) and various Java Application Servers (WebLogic, JBOSS)\ • Cloud Computing, such as Amazon EC2/AWS\ • Enterprise Data and Search technologies (Example: Solr, Hadoop, MapReduce)\ • REST / SOAP / JSON\ • Agile/SCRUM Methodology  

If you're involved in designing, developing, supporting, working with, changing, upgrading, or selecting some sort of content management system, you owe it to yourself to read this article and heed its advice.  A good content model is important to make a system useful to the intended users.  A good content model also has to be flexible and extensible, especially as you iterate and improve it.  A good content management system has to be pliable to meet your content model, instead of imposing its own one-size-fits-all model on you.  However, that flexibility means you'll need custom development to get what you want.

As Karen McGrane says, it's easy to sketch a faceted navigation on a wireframe. It's more difficult to implement a CMS to power the implied taxonomy, and to commit to ongoing editorial maintenance over time. A wireframe without a corresponding content strategy and a realistic CMS design is a work of fantasy. A CMS that could realize one of these fantasy wireframes would need plenty of magic pixie dust. We need content strategy to help us decide which of our aspirations is feasible; CMS design is an essential part of that decision.
