The US is already behind in its agreed to commitment to clean power A study just out in Nature climate Change suggests that the US is already behind in its commitments to reduce the use of fossil fuel as an energy source, and the concomitant release of climate-warming greenhouse gasses into the atmosphere. The paper,…

What we need to do to stop global warming

Obviously, we need to stop the human enhanced extra greenhouse effect. There are a number of ways to approach this. Let me say right away that taking CO2, the main greenhouse gas of concern long term, out of the atmosphere is NOT one of the ways. Here’s why: It takes energy to put Carbon into…

By important, I mean people who have their hands on the levers of power, more or less, in areas that affect energy policy. I don’t really care if Uncle Bob doesn’t accept climate change. Uncle Bob votes for right wing yahoos anyway, that wasn’t going to change. Why should it matter what Uncle Bob thinks?…

Here’s the abstract from the paper describing this work: To realize the sustainable energy supply in a smart city, it is essential to maximize energy scavenging from…

Michael Mann has an editorial on Scientific American’s site putting the well known 2.0C limit in perspective for the upcoming climate talks in Paris. Mann makes a number of important points in his essay (read it here: Meeting a Global Carbon Limit Is Cheaper Than Avoiding One) but there is one point that I want…

As an anthropologist, I find the interface between technology and the larger culture in which it is embedded fascinating. You all know the old story of the family cook who habitually cuts the ends off the roast before slipping it in the oven. One day her child, hoping some day to be the family cook,…

RMU Announces Solar Plant Completion Rochelle Municipal Utilities, in Rochelle, Illinois, has. started operation of a large Photovoltaic Solar Plant providing power to their water treatment facility. This is a great example of a project that should be done in more places. In the Spring of 2014, RMU was awarded a $500,000 grant from the…

Thinking Big About Clean Energy

I want to put a solar panel on my roof so that I am releasing less greenhouse gas into the environment. But then I hear that manufacturing solar panels causes the release of greenhouse gasses, so I have to subtract that from the good I think I’m doing. But then I realize that the people…

No Coal in Minnesota

Governor Mark Dayton has called for the elimination of coal as a source of energy in Minnesota. Doing so is, clearly, essential. Having a governor call for it is a new thing; we are only seeing this sort of policy being developed recently. From MPR News, Dayton said to a group of energy policy ad…
