We’ve had some recent activity around commercial refrigeration performance here at Powerhouse Dynamics, which got me thinking about how our personal refrigerators are performing. Similar to a recent post I did on my dehumidifier, I decided to take a look at “real-world” energy consumption data of several refrigerators versus manufacturers’ specifications. In a previous post on my least […]
Just one year ago, Aneesh Chopra, the US Chief Technology Officer who also serves as Associate Director of Technology at the White House Office of Science and Technology Policy, challenged the utility industry to provide customers with easy access to their electricity use data. The “Green Button” initiative was to be modeled on the “Blue […]
For a long time, I viewed my energy usage as something that my parents always told me to watch, but not as something that could start to improve my life in the short-term. At home, I would leave the light on in my room when I was at school for the day, override the settings […]
Energy Efficiency Delivers the Green… increased profits, that is Too often I hear people describe energy efficiency as a “do-gooder” kind of thing – something to “help the planet”, but with no other intrinsic value. Part of this may relate to confusion between the terms “efficiency” and “conservation”. While there are clearly overlaps between the concepts, […]
I live in a 70-year-old house just north of Boston. I’ve mentioned in a previous post some of the things I’ve done to try to reduce energy consumption in my home, including changing the operating mode of the dehumidifier in my basement so it runs less frequently but still maintains the proper humidity. Now that summer is […]
I generally try to keep politics out of things that I write. (Okay, maybe that is a gross exaggeration.). But, the recent barrage of the phrase “job killing regulations” has driven me over the edge – and reminded me of a very interesting graph I saw a couple of months back. I am clearly not […]
This is the 3rd in a series discussing my experience driving the all-electric BMW ActiveE. Oops Last Tuesday the odometer hit 1,000 miles. Last Wednesday the thermometer in Boston hit 96 degrees, a record for the day. Last Wednesday evening the car would not start. Coincidence? I still don’t know. The dashboard message read: “Drivetrain malfunction; […]
With the first day of summer officially in the books, the cooling season is on for the lower 48. Yes, Florida and Arizona and San Diego have been cranking air conditioning for weeks if not months by now, but the real heart of the cooling degree chart is now just in front of us. In […]
I live in a small town just north of Boston. Two weekends ago, we held our annual “Town Day”, which is a town fair where they close-off the roads in town center and have a bunch of activities and performances with fireworks at night. It’s a classic small-town event — tons of fun and a […]
In my last post I disclosed that I had just taken delivery of one of 700 all electric ActiveE’s that are being leased by BMW. The ActiveE is based on the 1-Series BMW. What’s it look like? The ActiveE looks just like a BMW 1-Series, with the exception of the geeky lettering and circuit imagery […]
I am not generally an early adopter. I am a geek, but a cautious one that typically waits until the 2nd or 3rd generation before acquiring new technology. I began lusting for a Tesla Roadster the first time I read about the car long before its debut, perhaps 5 years ago. Having spent the first part of […]
Part 2: Reducing Peak Demand for Commercial Facilities Last week, I described how the team at the Historic Green Village – a sustainable commercial development in Anna Maria, Florida that includes a café as well as retail spaces – used SiteSage (formerly eMonitor) to improve their energy efficiency and reduce their overall energy consumption such […]
