EE, Policy, and Irony

24 05 2011

As my crop of silver hair continues to expand, I have become more of a historian, particularly when it comes to cause and effect, and peoples’ behavior.  I step back and observe what is happening and what has happened as a result of this or that policy.  Theories are nice, and they may be well thought out and make sense but if they fail miserably, should we double down and try it again?  Policy isn’t like launching rockets or breaking the speed of sound.

For those things, you can test, observe failure/problems and make adjustments.  For example, Chuck Yeager was the first to break the speed of sound in an airplane.  As he did so, the vehicle, which looked like a beer keg with wings (tap included), shook violently and about blew apart.  Why?  Because it had straight wings, not “delta” shaped wings.  The tap of the keg was led by a shock wave that emanated back in a V, kind of like the wake behind a boat.  The straight wings resulted in the ends leading the beer keg’s shock wave and the portions closer to the fuselage were safely behind the shock wave.  There is a large difference in pressure upstream and downstream of the wave causing instability and the violent vibrations.  They learned.  Sweep the wings back so the entire wing is post shock wave.  All supersonic aircraft have since been designed that way.  Google for pictures of the Blackbird, Concorde, Stealth Fighter, F-14, 22, and a gazillion others and you can see this delta wing design.  You don’t see this on your basic subsonic A320 passenger jet.  Mechanical engineers should already know this.  If not, they went to the wrong school or slept through fluid dynamics.

Policy, on the other hand, does not work this way in my opinion because policy affects infinite variables and you are dealing with peoples’ decisions on a macro basis, not physics.  When accounting for decisions made by 300 million individuals followed by a chain reaction of decisions that is limitless, you will get the same results from the same policy every time.

Keynesian theory (stimulus), for example has failed, what a thousand times, not counting the depression?  But we keep trying.  See this damning report by two Ph.D. economists, one from The Ohio State University and one from the University of Western Ontario.  The Act “saved or created” 443 thousand government jobs and “destroyed” about 1 million private sector jobs.  I wonder if the study was funded by ARRA!  LOL!  Has anyone seen Joe Biden lately?

I could write a book regarding why it doesn’t work on a macro level, but let me just provide some reasons believers give for it not working: it wasn’t enough money ($800 billion is almost $3,000 for every man woman and child in the country – how many flat screen TVs from China do we need?), it doesn’t work during deficit spending, the financial crisis, the Bowl Championship Series, La Nina, Rosie quit The View, people were busy preparing for the apocalypse that failed to materialize over the weekend  – you name it.

Likewise, it’s been a bomb for energy efficiency.

  • Utility and regulatory stakeholders in Iowa opined they couldn’t wait for the funding to stop so people would get off their hands and get in the game again.  Now that ARRA is wearing off, an objective observer can see this happening – the economy improving, slowly.
  • Cash for clunkers miniscule EE impacts.  Over an AESP conference lunch last week, I visited with an engineer from Southern Company, Alabama and he said the Honda and Mercedes plants in their service territory were running around the clock, full tilt.  Post cash for clunker they were running at half capacity.  And savings?
  • A long time ago, I said the money going to EE needs oversight to ensure it isn’t wasted.  Well lo and behold, a few weeks after this we bid as a sub-consultant to evaluate the funds spent in California and won the project.  We haven’t seen a nickel’s worth of work yet.
  • With a business partner’s lead, we pursued pilot work to pursue some ARRA funds, despite my vowing not to pursue ARRA funds.  Result: $130,000 lost in work we will never be paid for.
  • We had a “shovel ready” LEED® project for a new federal building ready to go.  After dragging on for months, our LEED services were value-engineered out of it.  Did the OSU guy capture this?
  • In the past couple weeks we considered going after some DOE EE evaluation work with one of our best clients but dropped out once intelligence revealed a competitor was going to low-ball it with their “government rates”.  Reverse price fixing.  I wonder how the rest of their clients feel about this??

What else is ironic is I would say our industry is quite progressive, yet when politically favored are in power, EE gets the shaft.  Consider WI, which during the recession prior to this one, the Democratic governor Jim Doyle, almost collapsed the state’s energy program by taking HALF the budget dollars rather than cutting spending elsewhere.  In speaking with Californians last week at AESP, the same thing is on the table in Sacramento, with a Democrat uber-super-duper majority.  I said, I bet there’s uproar over that.  Not a peep.  How could this be?  Unions Trumpka EE, get it?

Meanwhile, on the right you have people like Rand Paul with his kooky bill to undo the incandescent ban; Glen Beck waxing hysterically that George Soros will use the CFL as a tool to overthrow the US government and Media Matters will control your smart grid connection; Bush and hydrogen; and of course there is a considerable faction of right wingers that would just as soon gut all EE efforts and drill, mine, build power plants, and power lines willy nilly, and waste resources per market forces.

Finally there is this triple lindy irony: the incandescent ban, signed into law by Bush, hated by right, generally applauded by policy people in our industry, is causing much angst for program people.  It’s taking with it a gravy train of easy savings for EE programs.  An entire cottage industry is developing to rationalize the legitimacy of maintaining these savings.  There’s a problem though.  I can get CFLs on for less coin than the less efficient halogen.  We may actually see incentives for throwing away working incandescent light bulbs (just guessing).

Will the Republicans dismantle our industry?  It’s probably not going to happen in Wisconsin.  A friend (Shaw) of a friend (Koch) of the governor is the administrator!  What a hoot – a story for another day.

Don’t Mess with the Stapler

5 04 2011

We, as an industry, have our work cut out for us in coming years.

Months ago an industrial energy efficiency consortium that puts on training events held a two-day workshop on motors.  Motors!  Talking about the common Swingline stapler for two days would be more interesting.  The efficient motor uses less energy in the amount of the difference in the reciprocals of old minus new.  I.e., (1/eff – 1/eff).  Multiply by nameplate horsepower then by 0.5 (don’t ask, just do it) then by annual hours of use.  Bingo!  There are your savings.  Two days!

There are more complex issues that may not be addressed.  One of these issues is, what is it that makes a motor more efficient?  Tighter windings and closer tolerances – I think.  I don’t care because the impacts are infinitesimally small compared to what end users ought to be doing.  This results in less slip, which means the efficient motor actually runs faster.  Here is the dirty secret:  An efficient motor may be three percent more efficient but as it runs faster on a constant speed fan or pump it would increase shaft power – power transferred to the impeller / fan wheel by 9%.  Increasing the load by 9% but doing it more efficiently by 3% does not save energy.  Quite the opposite, actually.  If one changed sheaves, which isn’t going to happen, or if the equipment is properly controlled by a variable speed drive, it may actually save energy.

On the whole, it is highly possible that efficient motors result in greater energy consumption.

Recently, we were meeting with regulatory staff and the topics of lighting and motors surfaced.  Apparently, the investor owned utilities are clinging to, and concocting ways to hold onto savings for efficient motors and lighting; minimum efficiencies for which thanks to the benevolent federal government are being ratcheted up by fiat.  Clinging like Milton and his beloved stapler.

Give me a break.  If programs are still relying on savings from motors, there is a major problem in Denmark.  How about considering what the motor is turning?  The load on the motor could probably be reduced by 50%, while they are going to “save” 3% with a stupid new motor that runs faster and uses more energy.

I can see what is going to happen.  Some utilities are going to whine to the regulators that all their savings opportunities are going away because the feds have ratcheted up standards.  Regulators should respond with the equivalent of “Gee, that’s really unfortunate.  Since you’ve installed all these motors that use more energy over the years, I think we will raise your savings target by one additional percentage point.”  Ironically, I learned that negotiating tactic from a utility.  “You think the penalty is too harsh?  I’ll add 50%.  Would you like to counter that again?”

Ironically, on the same day as the meeting with the regulatory staffer, I received information I had asked for purposes of evaluating the potential for retro-commissioning of a mid-size high school just over 250,000 square feet.  I had asked for the energy records.  The facility is using at least 50% more electricity than it should and 50% more natural gas than it should – easy.  It is using as much energy off peak as on peak.  The power factor is lousy.  With these symptoms, I bet I can call three top, major energy saving opportunities given the types of systems they have.  I’ll just leave it at that because it’s intellectual property available for a price.

I’ll bet my house that we can reduce their energy consumption by at least 30% with well under a five year payback.  It could be one year or three years, depending on what needs to happen to fix the causes of the waste.

Trust me when I tell you, efficient motors and new lighting will not be part of the 30% solution.


On the nearly useless EE front, see which internet browsers are most efficient.   However, the impact on battery life is worth noting.  If you don’t use the overpriced internet during air travel, kill the browser.

The president says federal vehicles will all use “clean” fuel by 2015.  What does that mean?  One percent of the fuel will come from reconstituted plastic grocery bags recovered from a landfill?   Meanwhile, the federal vehicles excluding military, guzzled 7% more gasoline than the previous year, using 322 million gallons of gasoline.  Congratulations.  I’m always pleased to be told how to live by hypocrites to whom no rules apply.

Pregnant Snake Armpits

1 03 2011

Although I don’t appreciate talking about it, we have a black list of companies and organizations for which we will not again partner with, work with, or bid their request for proposals.  What type of activities land somebody on this list?

Companies or organizations that take our business development efforts and give it to someone else.

We are working on retro-commissioning for a major player in the Midwest grocery market.  As with most of our investment-grade studies for energy retrofit or retro-commissioning, we like to use contractors to provide us with pricing because we expect they will get the work and therefore, the pricing is going to be more accurate in addition to having accountability for the prices at implementation time.  The contractor was very reluctant to help because he was afraid he would help develop pricing and concepts and then somebody else would get the work.  I laughed out of familiarity with such shenanigans.

Unfortunately, while working on the grocer project, we were victims of just what the contractor was talking about, on a different project.  We had completed an energy study for a quasi non-profit, quasi-government outfit (Jeff, how many times do you have to get burned before you learn?) and we were moving into developing the design and provided a proposal.  We had already pretty well nailed down the scope of the project.

Inject another righteous government agency to “help” this end user.  Well, they took our developed scope of work and put out a competitive request for proposals with OUR work on it.  So now we’re faced with throwing away all the development we had already done just to be competitive with the other bidders who were handed this on a silver platter.  As I wrote last week, it’s a rainy day in hell when a government outfit takes anything but the low bid, otherwise known as the cheapest, crappiest system imaginable; one that meets only the major recognizable features, like equipment efficiency.    There are plenty of places to cut cost on the design and on the project itself.

That agency is blacklisted.

Companies that use our credentials to win a job and then dump us like a cheap date.

Last year we had “teamed” with a local architect on a LEED project for a new nearby federal facility.  I must digress for a moment.  This project was in progress when the “stimulus” was passed – you know the one that was supposed to break loose the shovel-ready projects.  If this wasn’t shovel-ready, I don’t know what was.  The plans and specifications had been lying about for year or two waiting for approval to proceed.  It drug on for months once the stimulus passed.

Come to think of it, this one too was in our hip pocket and they bid the work out again.  I’m not sure why because the design was 90% completed but I suppose some milestone had passed and federal statutes required a rebid or something.

So now that it’s competitive, once again after doing a bunch of development and front end work, we have to cut cost to beneath the cheap and crappy level.  So our client, the architect asked us to chop our down our price.  We provided a counter offer and waited.   And waited, and waited.

We already had 20 or so LEED projects under our belt compared to near zilch for the architect.  Finally, we get a hold of the scumbag, er, I mean client, and he says, oh yeah, “The good news is, we won the project.  The bad news is, you aren’t on the team.”  This is lower than a pregnant snake’s armpit.  (stolen from the aussies and modified by me).


Companies or organizations that use our proposal in attempt to beat “their” firm down in price.

This one is more difficult to nail down but let’s just say if it walks like a duck and quacks like a duck…  A large organization pursued by a bunch of consultants / contractors has been working with a provider for years and maybe they want a new or modified service, or maybe it’s just the same stuff they’ve been provided with many times.  Now they suddenly want a proposal from us.  This is either a Sarbanes Oxley corporate requirement (ok), process to actually evaluate invited bidders (ok), charade to fake a bureaucrat into thinking the chosen one was competitively selected (not ok), or a hammer to beat down the firm they know they are going to hire (not ok).  Essentially, we are wasting a bunch of our time to benefit only the buyer.  The other bidder(s) gets screwed too.

Blacklisted after a few of these – typically takes a few rounds of abuse to have this scam come into clear focus.

Wolves in sheep clothing.

Over the years we’ve been pursued by numerous companies that would like to partner with us.  It would be a marriage made in heaven.  Next step: an initial public offering on the NASDAQ!  Uh huh.  Sure.  These dirt bags just want access to our clients and for some reason, controls companies and performance contractors make up a substantial portion of this bunch.

Show me the money before I lift a finger or you are blacklisted.

A better way.

Recently a business partner stated it well, “What do we have in business and life but our reputations?”  And I always say to our company’s people, you best treat well everyone you work with in the company, our clients, and even the competition.  You never know who will one day be your client or supervisor, employee, or maybe someone you want to partner with, or get help from.

Everyone involved in business transactions should benefit – consultant, owner, utility, shareholders, and contractor.  Clearly and unfortunately, some entities think they can get ahead while screwing others and thinking they are getting a good deal or making extra profit.  Sooner or later these outfits run out of victims to exploit.  It shouldn’t be a fixed pie that everyone fights over.  It should be a pie from which everyone’s slice grows.


It appears Sacramento is contemplating the same fateful robbery of EE program dollars by hocking the stream of energy efficiency money.   In WI, this grab actually happened and crippled programs.  Ironically, or maybe not so, they would be both carried out under Democrat governors.

Outrage of the Week

Maybe I should start an outrage of the week?  Well here is the inaugural.  The DOE is calling it “Market-Driven Solutions” to work with behemoths like Target and Wal-Mart to develop new efficient rooftop heating and cooling units.  Is this the same Wal-Mart with $420 billion worldwide sales and $14.4 billion in annual earnings?  Chu, you have got to be kidding me.

Like General Electric, why doesn’t Wal-Mart get back to what they used to do well; innovate, rather than going to Washington with its hand out.  Time to put a “strong sell” on Wal-Mart stock.  They’re washed up.

This is a free market solution: an RFP for manufacturers of rooftop units to develop units that meet Wal-Mart’s specifications, reliably, and supply them with heating and cooling equipment for the next 100 stores.  After 100 stores, the incumbent has a huge advantage for (hopefully) proven success.

A portion of the $1.6 trillion, or as I like to say $1.6 million million, deficit is funding this kind of crap.  This wouldn’t be funny even if it weren’t true.

Oxymoron of the week: “DOE facilitates market-driven solutions”.

RFPs from the Edge

22 02 2011

Last month, the one session I attended at the AESP national conference was how to write a better request for proposal (RFP).  It was sort of a forum led by our friends at Tetra Tech.  Essentially, it was full of people like me, for whom a major responsibility is business development and marketing – responding to RFPs.  For a while I sat there like a lump, thinking, eh, just deal with it and quit whining.  Toward the end of the session I started getting fired up.

Here are some guidelines for writing RFPs:

  • If you’ve already decided who you are going to hire but have to go through an RFP process as a formality to keep some government wonk off your back, just issue the RFP with a one-week deadline with an impossible pile of content to gather so it is obvious to everyone who knows anything (i.e., not the clueless wonk), that the RFP is a charade.  I have plenty of opportunity without being duped into writing a proposal for which we have no chance.  And whatever you do in this scenario, don’t extend the deadline because some clueless bidder doesn’t “get it” and asks for an extension.
  • If you are going to extend the deadline, do it days before the deadline passes.  One thing that really smoked my butt last summer was having a deadline extended with about three hours to go for the 5:00 deadline.  This was obviously to accommodate some whining  bidders.  The RFP had been out for weeks.  If a bidder can’t manage their time better than that they deserve no chance at the project.  Is that how you would handle the actual work should you win?  I wrote as much in our proposal on that one, sparing the name calling, however.
  • If you are going to extend the deadline, do it before the original deadline.  That is correct.  We recently submitted a proposal on a Friday, the due date.  We added to the proposal that we had not received the questions (from bidders) and answers (from buyer) for the proposal.  Samples of this Q&A are discussed in You Are So Fired.   As a result of not having the Q&A, we wrote that if there is something we didn’t get from the guy who promised we would get the Q&A, have mercy on us.  The next Tuesday here came the Q&A and an extension to the next Thursday, two days away.  Good grief!  And it had MAJOR implications.  See next bullet…
  • If there is a deadline for completing the actual project, PUT THIS IN THE RFP! (please)  The RFP discussed in the previous bullet was for a quarter million dollars with no project timeline mentioned in the original RFP.  We provided two scenarios: first to complete it by late fall for one price and second to finish early the next year.  In the Q&A provided after the due date, the report was to be completed by June 30.  Nice.  If I had known that I probably wouldn’t have even bid the thing because it’s too aggressive and practically impossible to deliver.  Did I mention this was an ARRA (“stimulus”) project.  Makes sense that it makes no sense.
  • Either provide a very detailed scope of work or budget, or both.  If neither is provided, you have nothing to bid on.  This may sound like a “duh” but some RFPs want innovation and therefore leave the approach wide open, which is ok, but unless the RFP comes from congress, which knows no limit on spending, please give me a number to work with.
  • Know what you are doing.  We were recently teaming with another firm on a proposal for a relatively huge pile of work.  The constraints on cost per project and per unit of savings were about 40% lower than industry standards.  For example, a rule of thumb is that a program should deliver savings for about 1.5 times the energy cost per unit.  They were talking about something more like 0.8 times cost per unit.  C’mon.  This will be a case of hopefully getting the project and then explaining their plan is naive and needs a reality pill.
  • Keep it linear not a convoluted, semi-parallel piece of junk.  Some RFPs have an approach, scope of work, form of proposal, with a total of about 4 separate lists of things to cover.  I want to be sure to cover everything and present it clearly but this gets a little difficult when the format detailed in the RFP is a mess.  It doesn’t flow like I want because the RFP is a heap of junk.
  • Don’t mislead or outright lie about selection criteria.  When I see an RFP from a government entity with a proposal selection process that puts less than 50% scoring on cost, I know nobody put any thought into that.  Sometimes it’s a laughable 20% of the weighting.  It would be a rainy day in hell when a government entity doesn’t select the lowest cost proposal.  Quality and ROI rarely (and I do mean not always) matter to government entities, which is why we skip most of them.  I did fall for the ARRA one above, like a dope.
  • And of our wonderful utility clients, tell the purchasing / sourcing departments we are not designing a power plant, transmission system, or even a measly substation.  We don’t need to carry $20 million in professional liability insurance.  This may be asking for the impossible too, but ask the legal department to be reasonable.
  • Finally, for cry sakes hire the firm / team with the best proposal.  In the past year, we assembled a team to do a study for a regional energy efficiency consortium.  Our team put a lot of thought into the proposal and developed an outstanding approach and work plan.  I knew who our competition would be.  A firm that had done a million of these and they would switch covers on the last report, make some adjustments for the region and tell them what they tell everyone else.  If you kid yourself long enough, you’ll start accepting it as correct.  At some point you have to go to the streets and find out rather than tweak the last edition.  Our approach was to get real data from the ground up.  We lost to the mass-market provider and in the post mortem, the consortium rep couldn’t tell us a single reason why we weren’t selected.  In fact, she only told us how much they liked our proposal, over and over.  Head, meet wall.


I was in Austin, TX last week for my first real visit to the state.  Per my experience, there is no shortage of traffic.  Per the locals, the city likes sprawl.  It features a nice downtown and believe me when I tell you I’ve never seen so many people running in the morning darkness as there were in Austin.  Not in New York, Washington DC, Columbus, Chicago, Milwaukee, Madison, Minneapolis, Denver, Tucson, Phoenix, San Diego, Sacramento, Portland, or Seattle.  The only thing that I’ve experienced that was close was in the hills outside Silicon Valley.  And the Austin dudes are fast.  I was passed by three women in one six miler – four if you count one that pulled out in front of me and pulled away.  Fantastic!  These women were probably in their running prime but I’m not going to whine about my age till I’m at least 60.  But the average high temperature in July/August is 96F, which to me in WI, is a god-awful 4-H day, hazy, hot, humid, heinous.

Another Committee – Alleluia

7 12 2010

Hide the kids.  The DOE has spawned an energy and renewable advisory committee.   You know, a diversified products / technology manufacturer like 3M or DuPont should examine the Byzantine labyrinth of government agencies as a model to develop the next bullet, explosion, radiation, fire, water, and bio proof wonder material.  I have to believe that if they could weave sewing thread or maybe two pound monofilament fishing line into such a fabric it would stop a 40 caliber projectile at point blank and not even cause a contusion.

Why does the country need this?  Why does the country need a debt commission for that matter?  We have a full time congress for goodness sake.  Isn’t that what they are supposed to be doing?  I suppose this is this too much to ask of 535 FULL TIME bureaucrats?

As anyone who knows anything would guess, the committee is dominated by academics and government wonks, although at least there is one utility guy on there.  Therefore, I am sure we will have a cornucopia of far out recommendations from a distant galaxy.  Most likely it will be heavy on far out technology and more spectacular policies like 15% or is it 20% ethanol blends for gasoline.  Maybe they can mandate its use, block imports, subsidize it with our money, steal our watch and tell us what time it is too.

Do these people or anyone at the DOE realize there is an industry of private sector product and service providers that work on our home planet of Earth with end users (also home-based on Earth)?  We are constrained to pesky things such as the laws of nature and economics and consumer whims.  I’ve said it a thousand times and I’ll say it a million more times, the savings potential from cost effective measures from current technologies and services is at least 30%.  See the McKinsey report from last year as backup for my hypothesis by people who know what they are talking about.

On the other hand, I read that this group is only going to meet twice a year and judging by the agenda of the first meeting it appears they won’t be inflicting too much damage on the citizenry.  If this is all they are going to do twice a year maybe this is simply a resume stuffer organization.  “Served on the Secretary of Energy’s Energy and Renewable Advisory Committee” would sound impressive for an introduction for a keynote address at Yale University’s spring graduation, especially for graduates with degrees in renewable energy management.


FIFA (Federation International de Football Association) chose Qatar to host the 2022 World Cup tournament.   Qatar, a tiny tumor of a country jutting into the Arabian Gulf is about the size of Connecticut, or about twice the size of Long Island (although saying it’s twice as big as anything is misleading).  Temperatures during the World Cup there will approach 426F, just below the point of spontaneous combustion of flammable items like paper but fortunately for most World Cup fans, above the melting point of the vuvuzela.  I rather like the vuvuzela, at least as comes across on the TV.  It’s hilarious like a cloud of June bugs or swarm of mosquitoes amplified a couple hundred fold.

In addition to building nine new stadiums and renovating a couple others, they will be supplying OUTDOOR air conditioning for these stadiums.  They will probably need to build a couple thousand MW power plants as well.

South Africa boasted that theirs was the greenest World Cup ever.  If Qatar says anything about green, they will have to use Venus as the baseline alternative for measuring the savings realized.  If I were them, I would just go with it and say this is the most ridiculous idea of all time.  We will proudly burn as much energy as half the countries with teams at the tournament.

I can almost guarantee they will build a photovoltaic plant the size of the country in the Saudi Arabian desert and that’s what we will be hearing about.

Too see how much money people in this region have, do a Google Earth or Maps of Dubai.  Apparently there isn’t enough moonscape barren coast on which to build opulent homes, so they make their own islands or “palms” where the strips of land take on the pattern of the veins in a palm leaf I guess.  And they have all the huge sky scrapers including the world’s tallest building.  What for?  By the looks of it, the only people who work there must be those that take care of the people who live there.  And why the tall buildings?  My impression has always been skyscrapers are needed for land-locked cities like New York and Hong Kong.  UAE makes Phoenix look like the Amazon basin.  There is nothing there.  Just pave it over and sprawl out so there is something to do with your time – like drive your 12 cylinder Italian sports car to the spa, bank, casino and back home.  The place is so un-natural it creeps me out.

Freeloaders and Geniuses from the Universe Next Door

19 10 2010

You know what torques me off, or make that torques us off more than anything else?  I’m saving it for a future rant.  Stay tuned.

No really, it’s “prospective” clients, many times end users that have screwed up buildings beyond reproach or wasting energy as though they just want to release all the carbon locked up in fossil fuels and get it over with.  They ask for help but in no way intend to pay for it or take action for anything substantial.  We may have even demonstrated, clearly by benchmarking or other means with specific measures that they could make their utility shut down a 500 MW power plant if they would just do something.

But no!  They want to know something trivial like how much energy/money they’ll save with a system that will put unattended PCs to sleep and not mess with anything substantive.  Never mind every PC on the planet has this built in and it’s about as hard to negotiate as turning on the television.

They’ll ask how to catch a three pound shad when you have a loaded harpoon with a giant blue marlin at point blank range (just go with the metaphor even if it is totally absurd).  Take the damn harpoon and shoot the thing, man!  Well gee, I just don’t know.  I haven’t used one of those things before.  I might shoot myself in the foot.  Is that tip sharp?  And they keep coming back for more panfish advice.

You may have spotted these people in public.  They go to the grocery store around noon Saturday to eat everything available for sampling, for their lunch, and probably leave with a half gallon of milk and a loaf of private label bread.  They sample six beers in a brew pub, order a can of Pabst and leave no tip.

And then there are those who believe the utility should pay for everything, and I mean everything.   We were working a school district for retro-commissioning and I believe they have some good opportunities, but when the board discussed it, a genius said, no.  He wanted the utility to build a remotely-sited wind turbine (because their location is lousy for wind energy) paid by the utility to generate electricity for their facilities and do it on a net metering sort of contract.  I am not kidding you.  Gee, that’s a great idea.  Let me get right on that.  I almost got brain damage from oxygen deprivation.  I was laughing so hard.  I’ve heard of customer entitlement mentality but this was from another universe.  How do you calibrate a customer like that to life here on earth?

We also have to beware of death by a thousand cuts.  A client may only want a half baked high-level assessment.  No matter how loud and clear we describe WHAT the project IS NOT, after we present the results that clearly meet the contract scope of work, some start asking for details on specific measures.  Where do I buy one of these?  Do you know any good contractors?  What capacity of doohickey do I need?  Some utilities, thankfully, are offering compensation to answer these sorts of questions.

Think of it this way.  If your house is a hog, it’s probably because it leaks like a sieve.  You can’t just take a couple tubes of silicon and slop it on some windows.  I know what I don’t know, and I know there are a boat load of places for infiltration/exfiltration to occur and like life in the commercial and industrial world, if you want results, you need to hire somebody who knows what they are doing.  I’ll pay a guy $500 to do it right before using a buffoon for free, any day.

NOTE: This is not a solicitation to weatherize my house.


Wall Street Journal readers responded to the source article from last week’s column.

Commenting on the letters, the National Resources Defense Council guy projects avoidance of 300 large power plants and $12 billion in annual savings.  In an Energy Brief a couple years ago, I projected 156 large power plants (500 MW apiece) and $9 billion in savings.  Close enough for hand grenades but I’m guessing he’s a little heavy on the power plants.  Is there diversity figured into his numbers?

Osram, a German company is retooling one of its American plants to manufacture efficient lighting.  Meanwhile, General Electric is whining that it has to close its last lighting plant in the U.S.  Jeffrey Imelt is a terrible CEO for GE.  General Electric used to be an entrepreneurial innovative company under Jack Welch.  Now it is a company in search of markets for status quo products and services, and government handouts.  If you don’t innovate you die in the private sector.  It matters not what you do.

One guy argues CFLs will require more heating energy consumption.  Yawn.  Fuel oil would be cheaper heat and if incandescent bulbs are such a great source of heat, what about summertime?  The electrical engineer makes good points that CFLs are not as bright as advertised.  We’ve always recommended CFLs at 33% the power, as opposed to 25%, of the incandescent being swapped out.  This is essentially the next size larger CFL than “recommended” in the business.

Another guy plays the mercury card.  Yawn.  I dismissed that fallacy in the same Brief.

Soothsayer: Analyze This

7 09 2010

How many times have you read “we can create 40 million jobs and reduce our energy consumption by 90% if only we did x, y, and z.”  Lester in this article says by 2035 we can double our fuel economy.  Well I should hope so!  Lester is actually one guy that is conservative in his estimates/goals.  David Goldstein in the same article says we can decrease our energy consumption by 88% by 2050.  Now where does he or any other egghead come up with these numbers?

I had to laugh out loud regarding the results of an energy efficiency potential study I studied a couple years back.  This expensive study was to be used for energy efficiency program planning for the subsequent five years for a state which shall remain anonymous to protect guilt.  For commercial and industrial (C&I) programs, imagine a graph with two sets of data on it.  The bars represent the programs’ goals for the trailing and forward-looking five years each, and a line represents achieved savings over the trailing five years.  For the trailing five years the savings ran about double the goals, increasing a little each year – something like 5% per year.  Well guess what the goals were going forward – about double where they were at the time increasing about 5% a year.  Stupendously genius!  If I failed to explain clearly, the goals were just an extension of the past 5 years.  You could lay a ruler over the past five years’ points and draw a straight line to get the goals going forward.  Man, I wonder how much they were paid for that report.  At least a half million dollars, I’m sure.

Soothsayers who predict energy savings potential two-three decades out or more must subscribe to the same methodology, otherwise how can you possibly project what the savings potential is beyond ten years.  Engineers, good ones anyway, subscribe to a rule that says extrapolating data beyond the data set – into the future in this case –  is very dangerous.  The further out one gets, the huger the error.

I am confident that the world’s economies will become more efficient with time, if for no other reason, less energy consumption means more profit.  However, the savings curve over time may approach a limit of something like 20%-30% savings compared to today because there is a severe shortage of professionals with degrees in the physical sciences, e.g. engineering, who are knowledgeable regarding C&I energy-using systems and savings potential.

Here is an article that includes 10 ways to improve the energy efficiency of a commercial building.  As I read this typical list, I can tell the author most likely doesn’t know squat about outing real energy-saving opportunities in C&I facilities.  Do energy audits, use more efficient equipment (duh!), maintain equipment efficiency (duh!), insulate, and brainwash occupants.  These things can save substantial energy if the lights are on 24/7 and the chiller was made in the 1960s and it’s plugged with airborne fuzz including dandelion seeds and the like.  This list reads like a good set of tips for homes.

Where are the real savings?  In system design and control.  Heating sources have been approaching 100% efficiency for a long time.  It is also going to be difficult to cost-effectively produce chillers that are much more efficient than you can get on the market today.  You’ve got to pump water, move air, control temperature and humidity, and provide ventilation.  Until humans create artificial intelligence to control systems, these things always waste substantial energy regardless of how efficient, well maintained, how many audits you do, or how “aware” of energy your people are.

Then there are manufacturing facilities, some of which I swear were built by the seat of somebody’s pants and controlled by no one.  Compressors are running at pressures higher than they need to be.  Cooling water and heating water streams are mixed before a portion goes to a cooling tower and the other portion goes to a heat exchanger.  Pumps and fans are grotesquely oversized.  Equipment is controlled in series rather than parallel.  Chilled water is used to cool things to 110F.  Operators’ fault?   Maybe not.  These facilities operate for profit, and productivity including simply keeping the line going, is king.  Staff in these facilities run from one fire to the next.

I don’t know if I have ever seen “green jobs” and “engineer” in the same article.  Green jobs always seem to refer to people who weatherize homes or work at a wind turbine, electric vehicle battery, photovoltaic, or some type of renewable energy plant.  This is fine by me as I really don’t want that moniker.  However, this is symptomatic that at least 50% of energy consumption in all buildings is misunderstood at best and virtually out of control at worst.

Rather than or maybe in addition to job training for the green economy, how about some electives or advanced degrees even for engineering schools?  Six credits of electives or a masters degree in energy efficiency would go a ways.  It wouldn’t take me long to generate a high level curriculum.  Rather than throwing hundreds of billions at technologies and industries that are bad ideas (e.g., food-generated ethanol), how about investing in some smart people who can critically analyze and provide solutions to greatly reduce energy consumption COST EFFECTIVELY WITH NO TAXPAYER SUBSIDIES?!


Here is an all-to-familiar story of misguided priorities.  BWI Airport is spending $21 million on an energy savings performance contract and they are leading off with the installation of a bunch of solar panels.  Meanwhile, they are probably wasting energy as though they want to get their “fair share”.  I also just came off a conversation where a former science teacher at a school district is pressing for a remote, net-metered wind turbine – and they want the utility to pay for it.  Uhuh.  Another LOL moment.  They’ve done a grand total of zilch to optimize their facilities’ energy consumption as well.
