Measuring Matters

Perhaps the greatest challenge to promoting energy efficiency is that you can’t see it. People understand electricity produced from a PV collector on the roof, and a kWh meter can easily report precisely how much energy was generated. But with more-efficient products, savings cannot be directly measured; instead, one must reckon the difference between a real and a hypothetical situation. This complexity creates a lingering uncertainty whether the promised savings did or did not actually…

Today's Power Trip - Weatherization and Infrared Camera

by Don Ames,  www.detectenergy.com

Got a phone call from a Son today, he was down at the local Mall looking to exchange a shirt he got for Christmas. This is one of those times when I wish that cell phones would just go away. Why do we need to be in constant touch with everybody all the time?

"Yes son, I bought the shirt there and I don't know why I cut the tag off and I don't know what happened to the…

Applied Passive-solar Structural Design

Passive-solar has been known to work well but certain things about our architecture fail the thermodynamic efficiency test and there are reasons why.

First is heat-transfer through conduction, the wood, drywall, sheathing all having rather high heat-transfer coefficients. Next is convection from a heat-riser which takes the warmth of the floor and moves it to the ceiling.

Until these are dealt with they cost a lot of energy, if one is trying to not require external heating for…

Part 2 of: The "1-2 Punch" to HVAC "Not Understoods"

Proper sizing of HVAC equipment is smaller, and smaller means more comfort.

Probably the usual thought in the HVAC industry by technicians is that the units need to be made bigger for comfort. Perhaps this comes from the idea of coming home from work, and needing a set back thermostat to do its magic, and get the home comfortable fast,…

On-bill financing: Why isn't everybody doing it?

If someone told me they could improve the efficiency of my computer so that it operates quicker, at no extra cost to me, I can’t imagine I’d turn them away. Yet, the energy efficiency industry offers a similar option for homes and businesses and at least so far, consumers aren’t flocking to the programs.

On-bill financing gives customers the ability to finance energy efficiency improvements made to their homes and businesses at no upfront cost. Customers pay for the insulation,…

Fixing people, not just buildings

Electric utilities operated under a rarified business model for decades. Their customers were captive so they rarely had to think about what motivated them to buy. New government energy efficiency mandates have changed that, and done so with an ironic twist. Now utilities must figure how to get their customers to refrain from buying.

It’s not easy persuading people to stop using something they like as much as electricity. But behavioral science is coming to the rescue – or at least…

Calling All Inventors, Entrepreneuers, and Venture Capitalists!

One morning I realized that I could cut down my showering time by at least one minute if I could combine my shampooing and conditioning into one step. Inspired, I went to a high-end grocery store that I will call, “Whole Paycheck” looking for what has been an illusive item for me—a combination shampoo and conditioner that really works; someone stacking items in the hair-care section told me that no such thing exists.

It’s a tough invention, since shampoo and conditioner are supposed…

Energy Efficiency Jobs: Another Well-Meant Hustle?

Are Energy Efficiency programs we are participating in another well-meant hustle, or is there lasting prosperity to be had in our industry?

Know true costs; Save real energy

By Guest Blogger Kara Saul Rinaldi

More than half of the states in the nation have created programs to increase the energy efficiency of homes through a comprehensive approach that looks at all opportunities to save energy, from insulation to upgrading heating and cooling systems. When taxpayer and ratepayer dollars are used, it is essential that these programs are reviewed with a cost-effectiveness test that provides policymakers with adequate knowledge about the programs’…

What is Humidity and How Does it Effect Home Energy Savings

Are Realtors doing enough for “Future Generations?”

This time two weeks ago I was in Anaheim, California, at the National Association of Realtors’ Annual Conference, themed “Seize the Day“.

I am still struck by the bigness of it all. Not just the sheer numbers (over 20,000 of us!), but by the strength of the passion and the vision.  Yet I am still wondering, are we delivering what future generations of home owners need…

Solar Power Panel and the Pergola

Getting the Most out of Your Pergola, Think Solar Power Panel

by Don Ames,   www.detectenergy.com

Sitting in a meeting the other day, I was listening to a discussion on where to put half-a-million dollars worth of solar power panels. The discussion considered placing panels on roofs, on picnic shelters, and carports - it's not easy trying to find a place for a bunch of solar panels. After all, there are things to keep…

Why free energy perpetual motion devices don't work

The following appeared on my blog Mapawatt and is in response to the "free energy plans" that have infiltrated Google and Facebook advertisements. I'm afraid a large number of people get suckered into buying these and are left with junk.

Homeowners Becoming More Aware of Pending Lighting Changes

Consumers will soon face new decisions when purchasing light bulbs, and many don't even know it yet. Beginning January 1, 2012, lighting manufacturers will no longer be producing the popular 100-watt incandescent light bulb. For professionals in the energy efficiency industry, this has been common knowledge since the passage of the Energy Independence and Security Act of 2007. Although many consumers have been slow to understand the pending changes, awareness is trending upward, according to…
