Dryer Problems: Inefficiency and Fire

Clothes Dryer Problems Can Lead to Inefficiency and Fire.

by Don Ames,   www.detectenergy.com

Story appeared in my local newspaper the other day about an apartment laundry room that had dryer problems. It occurred to me, being the highly trained home energy auditor that I am, that any clothes dryer that had such a problem that it would catch fire, must have been a very inefficient clothes dryer for a long…

Merry Christmas to all!

Twas the night before Christmas, when all through the house

Not a cool draft was freezing, to wake up the mouse.

The owner called a contractor with knowledge so rare,

In hopes that great comfort soon would be there. 

The children were nestled all snug in their bed,

With nary a cough or a cold in their heads.

And Momma in her Kerchief and I in my cap

Had just settled down for a long winters nap. 

When from my neighbor there a rose such a…

Think of the ways we try to separate the outside climate from the inside climate. In a nut shell, that is the goal of an energy efficient house. Take a snowmobile or a dog sled and you will see a domed home made out of snow and ice.…

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,…

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…

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,…

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!

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…
