Friend Jerah sent this to me, pointing out that since I don't use a refrigerator, my family is among the .04% of the US population that constitutes the "deserving' poor. I'm so proud!
I thought it had to do with income, in which case I'm not, in fact, poor, but no, it is all about the appliance ownership! We're really getting somewhere now - who knew picking up a microwave at a yard sale or living in a subsidized apartment with an actual fridge…
sastyk | March 28, 2012I've always liked Tom Murphy's "Do the Math" work, and I really like his latest piece on phantom loads and electricity cutting. That's one of the very first steps for most of us whe we seriously try and cut our electrical usage, but one that a lot of people don't know to do about. We've been able to radically reduce our electric usage by a lot of the same strategies, and they really work:
One of the most important reductions one can make is reduction of baseload power: devices that consume energy 24/7. Every 1 W eliminated removes 9 kWh from the yearly tally and about $1 of yearly cost at…
sastyk | March 8, 2012Well, I guess I timed that last piece reasonably well ;-), no? As you may have noticed, I am at present typing this on the internet, rather than carving it into a stone tablet (actually I'd probably just use a pen and a piece of paper, but stone tablet does sound more apocalyptic), so the latest solar storm wasn't a big deal. Still, it does seem like because there are so many fun things that could take out electricity for an extended period - let's call it widespread outages for months, anyway - that it does seem to be worth talking about. So let's talk.
What do you imagine such an outage…
sastyk | March 6, 2012Quite a few years ago I wrote a piece arguing that the single most likely scenario for most of us having to deal with long term electrical shortages doesn't involve gridcrash scenarios, but the growth of poverty and utility shut offs. I suggested that people should be prepared to deal with electrical outages in large part simply because of the economic consequences of our situation. It isn't that I didn't believe anything could shut down the electric grid, I simply felt that realistically, the probabilities of more than short-term outages in the near term were pretty small.
In news that…
sastyk | April 26, 2011April is the month that utility shut-offs are resumed in much of the northern half of the country - it is against the law to shut off people's primary heating fuel during the winter, but when they can't pay their bills, generally speaking, April 1 means that you can cut them off. There has been some upheaval in our area, where an unusually cold spring has meant that there is still a need for supplemental heating, and many poor people with very cold houses.
I thought it was worth re-running this article - a version of this ran in 2005, and I've republished it several times since then. We…
sastyk | January 26, 2011The good news is that everyone was more or less happy about Obama's stated energy policy last night. The Republicans were happy because Obama was talking about a "clean standard" which actually means "let's burn fossil fuels in a barely less harmful way" - ie, let's switch some dirty coal to natural gas, and pretend that "clean" coal is a reality, and that nuclear plants will come online rapidly and without massive subsidies. The Democrats were happy because some Republicans might tolerate a "clean energy" standard that takes emphasis off solar and wind. And everyone was happy because we'…
sastyk | October 3, 2010I think the first time I really seriously reconsidered the American ubiquity of the dryer was when I was in college, and a friend of mine made a list of ten things she considered hysterically funny about Americans. Number 3, after paying more money for milk with the fat pulled out and something about our worldview, was that we consider it perfectly normal to buy an enormous box at great expense to do precisely what the air will do for you anyway. Put that way, and with her performance of "American justifying why they need a dryer," it was pretty humorous.
It isn't like I even had one much…

sastyk | December 8, 2009We're just about at the one year anniversary of the Northeastern power outage that had many people out this way out for a week or two last year, and what's the forecast up at our place? Snow, followed by sleet and icy rain and more ice. This seems like a recipe for trouble.
Being of a vaguely apocalyptic mindset, your blogiste is pretty good for a power outage, but it occurred to her that not everyone is probably ready. In fact, despite the fact that FEMA has *said* that in a crisis it may not be able to reach people immediately, despite the fact that an awful lot of Americans had extended…
rallain | February 15, 2009Someone complained about a teacher using this question and the answer was disputed. After some time, the teacher claimed that the answer was that lightning is static electricity because she looked it up on the internet. So, I decided to look also, here is what I found searching for "what kind of electricity is lightning?" in google:
Electricity Facts - Dialogue for Kids (Idaho Public Television)
A couple of complaints about this site:
First, I am not fond of the term "Science Facts". What is a science fact? Something that is proven true? This really is not how science works.
Second, I am not…
