Burning Desire for Efficiency
Ever wonder how efficient it is to heat water? Of course you have! Ever measured it? Whoa, mister, now you’ve gone too far!
Education
Information storms and the limits to information
Odum often drew an analogy between the way meteorological storms such as hurricanes disperse heat and the way that other systems do, including information systems. After Tom Abel’s excellent post last week on trends in education in a world in transition, it is a good time to share Odum’s analogy linking storms of information and weather storms. But to make that analogy, we first need a meteorology lesson, starting with the second law of thermodynamics.
Universities co-creating urban sustainability
The sustainability crisis has provoked an unexpected and dramatic response from academia. Until now, higher education institutions have tended to focus on sustainability within their own borders. This has predominantly been via sustainability education, research and designing green or carbon neutral campuses. Yet borders between society and academia are dissolving.
Goodbye faculty: What’s the point of a University anyway?
Education has a remarkably inelastic demand curve and even in a contracting economy people will spend their last dollars to educate their children. Along with healthcare, high-tech weaponry, food, water, drugs, and internal ‘security’, Americans will pay almost any price for education, which is why the Right has furiously worked to privatize it and as well the rest of these. In a time when economies around the globe are stagnating (due to flattening or declining net emergies) they are the last growth industries of the capitalist growth economy.

Spectral Extravaganza: The Ultimate Light
What do you get when you cross an astronomically-inclined physicist with concerns over energy efficiency in lighting? Spectra. Lots and lots of spectra. In this post, we’ll become familiar with spectral characterization of light, see example spectra of a number of household light sources, and I’ll even throw in some mind-blowing photos. In the process, we’ll evaluate just how efficient lighting could possibly be, along the way understanding something about the physiology of light perception and the definition of the increasingly ubiquitous lighting measure called the lumen. Buckle your physics seat-belt and prepare to think like a photon.
Tom Murphy: Time to be honest with ourselves about our looming energy risks
Tom uses simple, easy-to-understand math — yes, that four-letter word — to logically — I say quite logically — make the case that simply extrapolating past trends in energy and economic growth is not going to cut it. Instead, we face gigantic challenges and significant risks to our current model. Not least of which is, when asked what we will use when fossil fuels dwindle away, the most typical answer is I’m sure we will think of something. That is, our future of energy is a question mark right now.
Crash Course
In the midst of all the doom and gloom about the economy, where’s the hope for building resilience back into family and community finances? Which personal choices will make a difference in regaining prosperity? Join two experts speaking about where we’ve been and where we’re headed.

Seven myths used to debunk peak oil, debunked
Peak oil is a fact, not a theory. From US conventional oil production peaking in 1970 to global conventional oil production peaking in 2006 the figures are indisputable. Even institutions such as the International Energy Agency (IEA) and publications like The Economist that are not known for alarmism have admitted that oil production from conventional sources has peaked.
So why are there still commentators who refuse to believe peak oil?
