I hesitate to start this blog with the words “combined heat and power.”  You might stop reading.

Okay, so it’s not the Brad and Jen of energy. (That would be solar and wind.) But what it lacks in glamour, it makes up for in constancy and results. It’s an old guy, been around for about a century. And while its name might not sound green, it offers an extraordinarily efficient way to energize buildings.

About once a year, the American Council for an Energy Efficient Economy issues findings that raise the profile of combined heat and power, or CHP, for at least a couple of days.

Why bother? Because despite its ponderous name, CHP is a “Wow” approach to energy, one that people should talk about at parties as much as they do solar these days.

CHP units, often used at universities, hospitals and factories, put to good use the waste heat created in producing electricity. Usually, we just let this heat vanish into the sky. But CHP, a form of distributed generation, reuses the byproduct to heat and cool buildings or assist in industrial processes. CHP can produce energy twice as efficiently as a typical centralized power plant because it provides two energy sources from one fuel. We know it works because, as ACEEE points out, CHP “has been cleanly and quietly providing over 12% of U.S. electricity.”

If it’s so good, why don’t we use more of it? The US is trying – at least some areas of the country.

“CHP markets differ considerably among states,” said Anna Chittum, ACEEE senior policy analyst and lead author of ACEEE’s September 28 report ‘Challenges Facing Combined Heat and Power Today: A State-by-State Assessment.

Do you live in a pro-CHP state? Not if you’re in Alabama, Arkansas, Delaware, Florida, Georgia, Hawaii, Idaho, Iowa, Kansas, Kentucky, Louisiana, Michigan, Mississippi, Missouri, Nebraska, Nevada, New Hampshire, North Dakota, Oklahoma, Pennsylvania, Rhode Island, South Carolina, Tennessee, Virginia, West Virginia and Wyoming.

You do, if you’re in California, Connecticut, Illinois, Maryland, Massachusetts, New Jersey, New York, North Carolina, Oregon, Pennsylvania South Dakota, Texas, Washington and Wisconsin.

Not so long ago the green energy movement celebrated because President Obama used words like ‘renewable energy’ and ‘climate change’ in his inaugural speech. It was a first for a US president.

Now comes the downside of being a political darling.

Opponents of green energy – or rather opponents of its proponents – are using the collapse of California solar manufacturer Solyndra as weaponry. As Scott Sklar of The Stella Group said in his recent blog, “With politicians throwing brickbats at each other, the green industries are right in the middle dodging these projectiles.”

Sure, Solyndra doesn’t embody the state of the green energy industry – it’s just one company. But the average person rushing to work hears only the thud of the brickbats… something about solar and financial collapse, scandal, expensive green energy and wasteful government spending. They are left with the impression that something is amiss with the world of green energy.

How will this affect the energy efficiency industry?

Energy insiders are quick to point out that in the scope of energy failings, the Solyndra collapse is small. And, of course, solar and energy efficiency are two different industries, even if both are ‘green.’ But those are fine points that most people miss, as they pick up only the background noise about the Solyndra collapse.

Americans report in surveys that they are likely to retire later than expected as a result of this economic downturn that doesn’t seem to want to quit.  While that’s bad news for golf courses and Florida real estate, it helps one industry: energy efficient lighting.

We are squinting, rather than sprinting toward retirement these days. As part of the post-50 crowd, I very much appreciate good lighting in my work space, and I discovered that I am not alone in researching a recent report on lighting.

Why do we geezers need better lighting? A 60-year-old employee’s eyes receive only 40 percent as much light as a worker who is 30 to 40 years younger, according to a paper by Leviton. These older employees tend to dislike the one-size-fits-all lighting of most commercial buildings; in fact, find it stressful.

Lighting is best when tailored to the needs of the individual. This can be done by giving employees manual override of automated lighting, so that they can adjust brightness and color depending on what they are doing in their work station at any given moment. And of course that is one of the features touted by lighting control manufacturers – the ability of consumers to customize lighting preferences.

Why worry so much about worker comfort? Happy workers tend to stay in their jobs, and that saves employers money, says a white paper “Personal Control: Boosting Productivity, Energy Savings” by the Lighting Controls Association. New employees need about 13.5 months on the job to achieve maximum work performance. As a result, worker turnover costs a business about 1.2 to 2 times the salary allotted for the position. Research indicates that workplace design plays a significant role in employee satisfaction. And right now many people dislike the lighting, heat and acoustics of their workplace, even young folk.

Last week, we looked at how the energy efficiency industry is working on its cool factor (Dare I say sex appeal?), to make clean energy more accessible to the masses.

Perhaps a bikini charger doesn’t make much difference when the grid is under great strain as it was this summer; but it does get people thinking about alternatives that could lead to – or add up to – more important changes.

Time to shed some light on lighting. An energy efficient approach to lighting has gained traction in the commercial world – with wireless controls, dimmers and a clear ROI for building owners. But so far, consumer touch points have largely revolved around bulb efficiency standards – which are dull, governmental and even intrusive.

There are very cool things on the horizon, like Professor Haas’ LED-light-based data transmission, which could feed our hunger for greater capacity for cell phones and all things Wi-Fi. Here are some other lighting innovations that might generate excitement at home (or rather, at your slick downtown condo):

  • Mood lighting made simple. No, please – don’t get up. This LED lightbulb from Sharp comes with a tiny remote that allows you to turn the bulb on and off, increase or decrease the brightness and even adjust the color temp (for mood lighting, perhaps?) all without lifting a finger (er, ok, barely lifting a finger). Its life is long, its efficiency impressive, but perhaps more importantly – it has novelty potential we haven’t seen since the clap-on, clap-off lamp control. The bulbs start around $40 – not cheap for the average consumer – but then again, what are a couple of Jacksons compared to how smooth you’ll look on date night?
  • Party on the patio. The Oasys from Sol is a complete unit that houses their aiSUN controller, batteries, and LED fixture. When darkness falls, the party doesn’t have to end: reliable light (and again, spiffy dimming capabilities) can be yours. Although we must say, their website needs a few tips on more accessible language if they’re going to get through to us.
