Chart of the Day: U.S. Energy Consumption

We haven’t had a Chart of the Day in awhile, so I’m horning in on Bill Lindeke’s gig because I found a good one. This is from the Lawrence Livermore National Laboratory, via David Roberts at vox.com. That might look a little confusing at first, but it’s really not all that bad. Overall, the chart […]

Podcast #95: Energy and Carbon Consensus with Brendan Jordan

This week’s podcast is a conversation with Brendan Jordan, the vice-president of the Great Plains Institute, a Minneapolis-based energy and climate think tank. I sat down with Brendan last week at his office to discuss the political landscape of climate change policy, both locally and nationally. We discussed how to think about climate and energy […]

Chart of the Day: Minneapolis Electricity vs. Built Square Footage over Time

Via Brendon Slotterback’s Twitter, here’s a chart showing Minneapolis’ energy use and “built square footage” (i.e. the total amount of buildings) over time: As Slotterback says: Minneapolis’ total electricity use has declined 4% since ’06 while total square footage has increased 5.5%. At the global scale, preventing out of control climate change requires de-linking GDP […]

Chart of the Day: Land Use Requirements for Solar Energy

This chart shows the land area required to provide 100 percent of US electricity requirements in 2050, compared with other land uses in our great nation. Read this for a longer discussion of the land use impacts of low-carbon energy sources like wind, solar and nuclear. Some local land use conflicts have arisen in Minnesota recently […]

Chart of the Day: Additions to US Power Plant Capacity

This chart comes from the Institute for Local Self-Reliance, a national policy thinktank based in Minneapolis.   Basically it shows how “residential solar” (i.e. panels on houses) has become a meaningful mix in the new additions to the US energy grid. It’s something to think about when thinking about homes, or energy, or cities, or […]

How Much Energy Could Minneapolis Get from Solar?

Solar PV seems to be the current darling of the renewable energy world.  But how much “resource” is really out there?  How much should cities rely on the development of local solar resources to meet their climate and energy goals?  What trade-offs should urban cities make between desirable things like tree canopy and maximizing solar energy resources?  GIS tools […]

Chart of the Day: Travel Efficiency (Calories per Gram per Kilometer)

This chart from Scientific American magazine should blow your socks off. A friend of mine sent it to me a while ago. It charts a whole bunch of different “traveling animals and machines” and examines various efficiencies of movement. Say what you will about bicyclists, at least we’re not lemmings. These different data points seem delightfully random. […]

Chart of the Day – Energy Density v. Area Required

This rather obscure chart illustrates how space intensive different power sources are in relation to each other. The grey energy sources are renewable, while the white boxes are fossil fuels. Basically, it illustrates how much less dense many of the renewable energy options are compared to coal and oil. Not that they don’t also take […]
