YOU HAD BETTER BE SITTING DOWN WHEN YOU READ THIS . . .

As you may know, Cruz Construction started a division in North Dakota just 6 months ago. They sent every Kenworth (9 trucks) we had here in Alaska to North Dakota and several drivers. They just bought two new Kenworth's to add to that fleet; one being a Tri Drive tractor and a new 65 ton lowboy to go with it. They also bought two new cranes…

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…

There is a Weatherization Assistance Program Near You!

By Don Ames,   www.detectenergy.com

I receive calls on a regular bases asking me about help fixing the problem of being cold and whether or not I have heard of any Weatherization Assistance Programs. These calls are not about being cold for a day - while the furnace is fixed - or being cold for a week - while a few more dollars are scraped together to have the…

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’…

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…

Gas Heaters or Electric Heaters - which one for home?

There are plenty of concerns arising when deciding which home heating solution to invest in.

The market is full of options offering so many types of space heating devices one starts to wonder which one is the best choice. Usually the types considered vary from: portable gas heaters to electric space heaters like infrared heaters, ceramic heaters or portable oil-filled radiators.

There is no rule of a thumb answer for this but what I like to do is to approach the problem from…

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.

When the testing equipment is not small enough to accurately measure the leakage - then it is called zero - usually below 10 CFM of leakage.

Does anyone have experience with window films installed over e-glass? Is there a payback on south facing windows during the hot summer months? Or would transparent shades work better?

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…
