Momentum builds for energy efficiency...but is the wolf at the door?

It says something that Ernest Moniz chose to deliver his first public talk as US energy secretary to an energy efficiency crowd.

His appearance last week at EE Global in Washington, D.C. was a surprise of sorts. And the timing was significant. Moniz had only been confirmed as energy secretary three hours before taking the podium at the Alliance to Save Energy’s annual conference.

Why did he make the stop?

Probably not because of the size of the crowd. About 550 people…

Since the 1980s, hot water condensing boilers (CB) have…

Change is Hard—How Do You Get People to Accept It?

Changing one’s daily routine and making big decisions about money is hard. When a home performance contractor asks a customer to consider an audit, they are asking a lot. Besides the cost of the audit and any retrofit measures the homeowner chooses to pay for, which is probably the biggest challenge, there is also the inconvenience. The audit and retrofit may require the homeowner to take time off from work. Having workers climb in and out of the attic, under the crawlspace, and drill holes…

HOMES Act introduced with Bi-Partisan Sponsorship

We don't see a lot of bi-partisan bills in Congress these days. Here's one focusing on home energy-efficiency from a WV-R and a VT-D, both on the energy committee, the HOMES Act, HR 2128 (http://hdl.loc.gov/loc.uscongress/legislation.113hr2128) introduced yesterday.  Now, I'm not holding my breathe on passage, but I take it as a good sign that energy-efficiency is part of the…

The Universe Is Made of Stories

The late poet and political activist Muriel Rukeyser famously said, The Universe is made of stories, not of atoms. It’s not just words that make up stories. A scientific equation is a story, and so is getting up from my seat and stretching—it’s the story of back care for an editor. We can tell a story with the expression on our faces. What does it tell you when a loved one rolls her eyes at you, or blows you a kiss? How do you feel when a stranger winks at you? Flips you the bird? That last…

Preparing to Update the Heat Pump

This is the latest from Foskey Road News, a business blog that is strictly consumer focused.

by Edward Foskey

Based on the life expectancy of the heat pump that came with my house when I bought it, I know that I am already living on borrowed time. I just recently had a minor repair and the semi-annual check-up. My plans are to start preparing to replace it by next spring.

Selling with Rebates: The Simple Payback

  The easiest way to show a homeowner how their investment in high-efficient equipment will help their wallet is to use the "Simple Payback" Calculation.  This 'tried and true' sales tactic will quickly explain how many years before the additional investment to upgrade is paid off.  Of course, there are many features that a high-efficient system provides, like superior levels of comfort, wether it be climate control or just condenser noise just outside their children's bedroom.  These…

Robert Shiller Says Retrofits Are Never Worth It!

His economic truth about homeownership:

By contrast, real home prices should decline with time, except to the extent that households shell out some money and plow back some of their incomes into maintenance and improvements, because homes wear out and go out of style.

"Here is a harsh truth about homeownership: Over the long haul, it’s hard for homes to compete with the stock market in real…
