On Friday, The New York Times published an article titled "In Fuel Oil Country, Cold That Cuts to the Heart." The article, about the Hartford's, an elderly couple in Maine who can't afford to pay for the oil needed to heat their (rather leaky) home, is both heart-wrenching…Continue
That's the name of a non-profit in San Francisco, with which Matt Golden is very closely associated, if not a founder. If you favor putting efficiency first, then that organization probably deserves your membership.
I don't understand something. What is the downside of putting efficiency first in a competitive environment? Thanks in advance for clarifying!

Everyone wants more and better leads, and a lot of people have been asking me recently about Lead Generation Services, particularly since I open sourced the Cost per Acquisition Model for Home Performance Businesses.
When I am at a residence in the middle of a Home Energy Audit and it is time to clock the flow of water at the shower nozzle in the master bathroom, I always feel like I am getting a little too personal. Have the people found what is the best shower head or are they using a gully washer of an energy waster. Have these people ever asked themselves, What is…Continue
What does it mean if the furnace filter collects lots of lint just like what the dryer makes???...Perhaps the dryer is venting inside and the filter is askew and leaks in the return air or filter gap are pulling it into the furnace. Check 'em.
What does it mean if the filter has three-dozen oak leaves pressed onto it?? Today I found an unusually high bill and a handful of foliage fallen from the neighboring trees. In the attic I found a donut of leaves under the vent where the screen…Continue
NewScientist’s January 28 issue is likely to unsettle clean energy advocates – but it is worth the read.
The cover article, “Power paradox: Clean might not be green forever,” posits that even renewable energy can warm the planet, and eventually change climate, if we continue to ratchet up power production to serve our ever increasing…Continue

Nick Magrisso recently posted a blog on the NRDC website highlighting the Carpenter Training Center in Elk Grove Village in Illinois as part of his series of exploratory video blogs on how energy efficiency is creating jobs in Illinois. It has been long recognized that a large amount of energy is wasted through improper or outdated building techniques. In addition to creating jobs,…Continue

When it comes to natural light and being able to see what is happening outside, windows would be hard to live without. When it comes to energy efficiency and…Continue
No, I’m not thinking of your grandfather’s hand saw . . . the one that cuts on the push stroke instead of on the pull stroke like the excellent Japanese hand saws.
Nor am I thinking of the beautiful (cast aluminum?) circular saws made by Rockwell right here in Syracuse for many years, but long since largely replaced by inexpensive tools made out of plastic and chewing gum.
(There are of course plenty of…Continue
I've made my living solely as a home energy pro since 2004, and I was building a high performance home for two years before that. For six of the past eight…Continue
Energy efficiency in the US is much light and little heat – literally. Government policy pays a great deal of attention to saving electricity, but focuses little on the thermal energy we waste.
“Policy is electricity-centric in the US. Unless you are making kilowatts, the most efficient investments are off the radar,” said Rob Thornton, president of the International District Energy Association (IDEA), who I recently interviewed while writing this year’s…Continue

Air sealing is important because air leaks through the walls, floor, and ceiling of your home. Air leaks out of your home when the air pressure inside the home is greater than the air pressure outside the home. Air also travels from hot to cold. The bigger the hole and the greater the pressure or temperature difference, the more air…Continue

You’ve been in the attic, the crawl spaces or basement, climbed up and down any stairs several times. There have been some questions from the home owner and perhaps from the kids in the house. If you are like me, you’ve bumped your head a few times on low hanging fruit. It has been a fun, rewarding and perhaps a little stressful.
The thing I do to relieve this stress, is to depressurize. Yes, let all that built up stress just…Continue

This is the era of Big Oil. Could the next be the era of Big Efficiency?
A new report by the American Council for an Energy-Efficient Economy suggests the possibility. Re-invented with today’s smart energy technologies, energy efficiency could displace 40 to 60 percent of our total energy needs by the year 2050, according to The Long-Term Energy Efficiency Potential: What the Evidence Suggests.
Sound far-fetched? ACEEE says history backs its…Continue
Vermont has a new comprehensive energy plan that is full of thoughtful - though non-binding and unfunded - ideas. The plan calls for meeting 90% of the state's energy needs through renewables by 2050.
Energy professionals know that it makes sense to dramatically reduce the energy requirements of homes and meet a large portion of remaining needs with renewables. We know how to do the work, what we don’t know is how to pay for it – solar panels and insulation are just…

How SmartHours Plus works: It costs more for electricity during peak periods of high customer demand.
Other factors, like weather conditions and the time of year, also drive electrical prices higher. SmartHours Plus,
sometimes known as Variable Peak Pricing (VPP), allows you to save when costs are lower, or off peak. Peak hours
are 2 to 7 p.m. weekdays, and prices during those hours vary based on demand (see chart). You’ll get advance
notice of tomorrow’s peak price the…
