Examining the Validity of Different Energy Resources
My friend Cameron Atwood and I were talking about energy policy the other night, and I promised to get back to him about the levelized cost of energy (LCOE) and the energy return on investment (EROI) associated with each of …

Variable Energy Resources Vs. Baseload
Here’s a comment to which I’d like to respond. A reader notes in connection with my post on wind energy: All wind and solar are only good up to a point. When they power flexible demand, they have some benefit. …
Untangling the Contradictions that Surround Our Energy Future
Here’s my first and long overdue post on the energy think tank Post Carbon Institute, whose work I think readers will admire. In brief, it’s a group intent on providing an objective analysis on energy resources on this planet, and pointing …

Scientists: Earth Endangered by New Strain of Fact-Resistant Humans
Here’s a fantastic piece in the New Yorker. There are probably 20 posts here related to the bizarre repulsion for science maintained by the common American, but none handles it with panache like this.
Per Capita Energy Consumption
There are two important takeaways from the graphic here: • We Americans use huge amounts of energy, and feel completely entitled to do so. Insofar as there are no pressures that would militate away from this level of overconsumption, it’s …
The Vicious Cycle of Ocean Acidification
In many cases, the challenges of sustainability are made more difficult by various vicious cycles, where certain bad phenomena feed on themselves and thus enter a pattern of ever-increasing acceleration. A good example of this effect is ocean acidification, which …
From Guest Blogger Charles Bell: Three Ways The IoT Can Help The Environment
When you hear about the Internet Of Things, or IoT as it’s commonly abbreviated, it’s usually with regard to convenience and knowledge. We’re using advanced exercise trackers to gain better understandings of our own fitness, integrating with cloud technologies to …
