The world is starting to pay greater attention to energy harvesting, through which ultra-low power sensors and controls can be powered by ambient energy flows (like light, heat, motion, or stray radio and TV signals). This week, Electronics Weekly reported on a study that estimated the current market for energy
Read moreAs if in reply to my missive about hazards in political polling, Politico has a great story today about just how far astray likely voter screens can lead even seasoned political professionals: For Republicans, one of the worst parts of the GOP’s 2012 trouncing was that they didn’t
Read moreI had great fun this past Wednesday (October 31st, 2012) talking at ARM’s Tech Con event, which is probably the world’s largest gathering of technologists devoted to low power innovation. Compared to my Authors@Google talk, I’ve added some additional examples of ultra-low-power computing and communications and
Read moreAs the election approaches, I’ve been musing over the nature of political polling. There are many folks who make a living reporting on poll results, and a few who actually do solid analysis using such polls (with Nate Silver at 538 being the most prominent and sophisticated example). Unfortunately,
Read moreMany observers have been heartened by the increase in natural gas production, which has contributed to significant significant declines in US greenhouse gas emissions. It is not actually the most important factor reducing emissions in the first half of 2012, as my friends at CO2 Scorecard and I showed earlier
Read moreOn October 1, 2012, the Brattle Group published an update to its 2010 numbers on coal-fired power plant retirements, and it “finds that 59,000 to 77,000 MW of coal plant capacity are likely to retire over the next five years, which is approximately 25,000 MW more than
Read moreI had great fun at Google on September 12th, 2012 talking about the implications of computing efficiency trends for mobile sensors, controls, and computing more generally. This version contains my latest thinking and is my most polished version to date. You can watch it below (or by clicking here). My
Read moreKCRW in Santa Monica, CA had a discussion show this morning (“To the Point”) about electricity used by data centers, prompted by the NY Times article by Jim Glanz. Jim led off the show in discussions with the host (Warren Olney), and then I, Andrew Blum of Wired, and Andy
Read moreKatie Fehrenbacher over at GigaOm did a service for those of us interested in data centers by compiling some of the issues with the recent New York Times article. She summarizes her conclusions (with which I agree) here: I feel the same way about the NYT’s series that I
Read moreJim Glanz, writing in the New York Times this past Sunday, described existing inefficiencies in Internet infrastructure, but omitted important context that can help interested readers really understand the problem. The article, in which I’m quoted, is Glanz, James. 2012. “Power, Pollution, and the Internet.” New York Times. New
Read moreWriting in Environmental Research Web yesterday, Evan Mills of Lawrence Berkeley National Laboratory reviewed Cold Cash, Cool Climate: Science-based Advice for Ecological Entrepreneurs. Here are the first couple of paragraphs: Entrepreneurs and investors alike will profit from Jonathan Koomey’s new book on how to cool the climate while garnering
Read moreThe folks at PARC have posted online a 2002 talk on climate change by the late Stephen H. Schneider. For those who didn’t know Steve, he was a genius unlike any other, and a very interesting speaker. I heartily recommend that you check it out.
Read moreI teamed up with the folks at CO2 scorecard to analyze the causes of Q1 2012’s record low carbon emissions for the US, and you can read the full research note here. The summary findings follow below: In this research note we show that the mild winter of 2012
Read moreThis two-pager gives the CBO’s latest estimates of what caused the increase in deficits in the past 11 years (for a bit of high-level discussion of the results, go here). For those interested in causality (i.e., which actions are responsible for changes in the deficit and national debt)
