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,…

A lot of higher education institutions are old, and back in the day, things were different. Not only were most schools simultaneously on top of and on the bottom of great snow covered hills, but they were often surrounded by nearly medieval settlement, or at least, pre-industrial ones, that lacked things like central heat, electricity,…

Harvesting clean energy in cities

There is a new technology that can convert both solar and wind energy into electricity in such a way that it is suitable for use on urban rooftops. 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…

Climate Change: What Everyone Needs to Know® by Joe Romm is just out, and is the most up to date examination of climate change science, the effects of climate change on humans, policy related problems, and energy-related solutions. Everyone should read this book, and if you teach earth system sciences you should consider using this…

Clean Energy: The State of the States

One of the problems we have in making a quick transition to clean energy in the US is the fact that energy production and distribution is typically regulated by states, and some states are not as smart as other states. Or, if they are smart, they are controlled by political forces intent on maintaining fossil…

Should you buy a hybrid car?

Last summer we were driving up north, in our Prius, and one of those coal rollers tailgated us for a while, then passed us. On the right. On the median. Jerk. When we were trying to decide whether or not to buy a Prius, last winter, I looked into the usual things one looks into.…

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…
