first_imgThe differences between Neanderthals and modern humans were not due to evolution for bigger brains or anything of the sort.  They were due to genetic drift, says an article on Live Science.    “A team of anthropologists has compared measurements of Neanderthal skulls to modern human skulls, and argues that most variations among them are the result of random changes that occur over time, and not of adaptations driven by natural selection,” the article states up front.    Don’t chalk up the differences in modern humans to bigger brains, better eyesight, better noses, or better ability to survive and reproduce.  That’s the assertion of Tim Weaver and a team from University of California, Davis.  The article says, “This finding may contradict a common belief that humans won out over Neanderthals because they acquired helpful physical changes in their skulls.”    Erik Trinkaus, anthropologist at Washington University in St. Louis, agrees. When we look at the archaeology, there’s essentially no difference in their implied social sophistication,” he said.  “They use the same kinds of tools, they’re all burying their dead, they’re all using body decorations of some form or another.  They were equally effective at hunting animals.  In anything that we can measure, there’s very little difference between Neanderthal and modern humans 50,000 to 100,000 years ago.”    Trinkaus said the reason modern humans flourished and Neanderthals didn’t may have just been luck.Trinkaus explained that it’s like football.  One team wins one year, another team the next.  “Why, in more recent time periods, do you have some groups of humans with certain cultural advances who displace others?  It’s happened many times.  There’s nothing biologically superior about one group versus the other.”    If modern humans and Neanderthals diverged from a common ancestor 370,000 years ago, as the article claims, this would have to mean that two independent lines of humans converged on the same intelligence, culture and physical capabilities without natural selection – only by random genetic changes.    We need to keep repeating that the Neanderthal myth is dead.  Neanderthals were Homo sapiens, wise, intelligent, capable hunters who made art, buried their dead, survived and flourished.  Their traits overlap with those of other humans.  There is no reason to believe they were not fully human, capable of interbreeding with other Homo sapiens and talking and communicating with them.  They were members of the ONE human race.    The article dubs this a “counterintuitive hypothesis.”  It’s not counterintuitive at all.  It makes perfect sense to those not drunk on Dar-wine.  Neanderthals and modern humans were brethren; they were both descendants of the original created human beings.    The new evolutionary myth, that Neanderthals and “modern humans” (note the embedded evolutionary assumption) diverged from some mythical common ancestor 370,000 years ago, but never learned how to ride a horse in all that time, is no better than the old one.  Evolutionary myths are tales told about bones that have been sacrificed in homage to Charlie.  There’s no meat on them.(Visited 41 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

first_imgRick Chitwood did a study that showed that when you do truly comprehensive home performance work, the results actually exceed expectations. A surprising result is the stellar reduction in peak energy demand.MacFarland guarantees energy use in client homes. Mike can predict energy bills to a few bucks a month, which he then guarantees. He tracks so tightly that when a client buys a plasma TV, it throws his results off and he sees it. RELATED ARTICLES Hard Truths of Home PerformanceThe ‘Low-Hanging Fruit’ FallacyDesigning a ‘One Knob’ Incentive ProgramHow an Efficiency Program Killed My Business Has your experience working with an energy-efficiency program felt like the scene depicted in the photo at right? Did you feel that the correct and smart path departed from the paved path?Having many colleagues on both the program and contractor sides, it’s pretty clear that utility incentive programs, as they stand today, fail. Let’s do better. Better for homeowners, better for contractors, and better for programs too! The One Knob program design is an attempt to pave a path where people want to walk.In my earlier blogs, I talked about how a good program should have three goals: a focus on results, accountability, and market transformation.I also examined how “low-hanging fruit” thinking is an impediment to good design when it comes to home performance. This thinking is a big factor behind the dismal realization rates of energy-efficiency programs.I discussed how bigger, more comprehensive jobs have a higher likelihood of achieving good results because they gain better control of heat, air, and moisture flows. Bigger jobs are better for homeowners, contractors, and programs interested in energy reduction. Won’t contractors attempt to cheat the system?This question — an appeal to the “adverse consequences” fallacy — implies they aren’t cheating the system now. The question should be, “Will less cheating occur?” And the answer is a resounding yes! By removing reasons for cheating, cheating will diminish.The first year will be a bit wild while everyone figures out how to achieve accuracy, but it will be like being freshmen in high school: everybody will be lost together, and by sophomore year, everyone will know their way around.Results will be published. Contractors will project energy savings first and then will be rewarded based on how accurate they were. This means that contractors will be incentivized to be as accurate as possible. If they overstate savings purposely, they will pay a price when their accuracy ranking drops, just as car companies pay a price when their J.D. Power rankings drop. Cheating is counterproductive; overstating savings means a lower accuracy ranking and other potential penalties (more rigid job approval process, etc.). So the risk of contractor cheating to get consumers a few additional dollars incentive is quite low.Currently, programs attempt to manage this risk themselves through rules. Unfortunately, they end up artificially limiting job sizes, a result of chasing low-hanging fruit, as discussed in my earlier blogs.Paying incentives one year after the job (after actual energy savings are determined) would be absurd. Homeowners are unlikely to move forward with that much uncertainty. It will not serve as an incentive at all. Incentives need to be paid up-front with the job.Paying for the contractor’s energy predictions is the simplest way to pay incentives up front. Homeowners will never have rebates taken back from them, but contractors who consistently overestimate savings will drop in accuracy rankings. If a contractor has a 90% realization rate, that might be the best that year; others may have 50% realization rates from overestimating savings, and be ranked lower. Lower rankings will cause jobs to be challenged more by programs, slowing the sales process. Higher rankings will eventually lead to automatic job approval. So there are multiple reasons to play it straight. That’s the basics of One Knob. How will it affect you?One Knob is designed to be beneficial for everyone. Programs at first will have less work because the proposed program is far less complex, but as things scale up, this will change. In a future blog, I’ll touch on how it will affect you, whether you work for a contractor, utility, PUC, BPI, or a program. Isn’t paying for negawatts too simple?What is it that programs, utilities, and public utility commissions (PUCs) want? Energy savings to meet their goals. Incentivizing saved energy directly is the fastest and simplest path there.Why the heck do we create these wildly complicated structures of “Simon Says” and “Mother May I” to deliver those savings, and then fail at it? Most programs have 30-70% realization rates. In manufacturing, Six Sigma requires 3.4 failures or less in 1 million.Programs fail to deliver pretty much every time; for-profit businesses would be in lawsuits and out of business with these results. It’s clear that something isn’t working.Peter Drucker says, “What’s measured gets managed.” So why not incentivize and measure actual energy savings by paying for actual energy savings, or “negawatts”? (A negawatt, by the way, is a term coined by Amory Lovins that means saved energy, or negative watts.)Of all the parties involved in an efficiency upgrades, who has the most control of final results? The contractor, of course. The contractor should be incentivized to save energy. The contractor also has the responsibility to solve the problems that the homeowner called them for. Where does all of this need to happen? The kitchen table. Right now, continuously shifting program rules make this transaction onerous. Why not give contractors the power to predict energy savings and determine the negawatt incentive?This will result in bigger jobs that save more energy more accurately and more precisely, for much less public cost. Where current programs spend $1 to $4 per negawatt, this would work really well at 50 cents.Keep complexity out. This is critical. Programs can no longer make monthly or weekly adjustments to the program, complicating kitchen table transactions. At 50 cents per negawatt, the program is a junior partner and needs to behave as such. Fuel-agnostic (everything converts to kWh), improvement-agnostic, software-agnostic: be sure to avoid influencing the “how,” or failure and blame will rightfully continue to fall on programs. Why will anyone use the registry? Will consumers see it?Rankings are a marketing tool. Even if consumers don’t know about the registry, high-performing contractors will tell clients about their rankings. “Oh look, we can show this at the kitchen table.”If you are an Angie’s List Super Service Award recipient, or a Century Club contractor, are you likely to say something about it? Of course. So if you ranked #1, or even #4 in the region for predicted energy savings results, would you be likely to bring that up when you find out you’re bidding against #20? And would #20 want to go higher the next year?J.D. Power rankings are sought after by consumers and automakers alike. Not long ago, the industry was poorly measured, and made poor products. J.D. Power elevated Honda and Toyota, nearly bankrupting the Big Three. Today cars are of far higher quality, and manufacturers brag about their rankings. Isn’t the same thing likely in home performance? Accountability is the answer, since it focuses on resultsThe solution is simple: publish results in a registry. If a contractor wildly overstates predicted savings, it will push that contractor down the rankings and make it harder to sell projects next year. The focus stays on the results: solving client problems and saving energy. We have found that well designed projects solve homeowner problems and save substantial amounts of energy, so all parties get what they want. So, what are you thinking?If you are feeling a ton of objections, that’s normal. Remember in an earlier blog, when I asked about your reaction to new ideas? I advised that and if you are a “no, no, NO!” person, you should move on. This is why. The One Knob idea is new, and questions are normal.Here are a few common questions:Isn’t paying for negawatts too simple?Won’t contractors attempt to cheat the system?Why will anyone use the registry? Will consumers see it?Aren’t accuracy and precision impossible for home performance?How can a program be fuel-agnostic?center_img In my last blog, I touched on some hard truths of home performance that are holding our industry back from scaling up. Markets cannot be administered into existence. Capitalism doesn’t work that way. Trust and confidence in positive outcomes, where the benefits are greater than the effort, is critical for scale. Currently there is no confidence that home performance programs will deliver results. How would we know when they’ve never been an objective? If you don’t track and reward accuracy and precision, why would you expect it to exist? Furthermore, there are indications both in academia and in the wild that when you are truly comprehensive, high levels of accuracy and precision are possible.Danny Parker of the Florida Energy Center, Rick Chitwood of Chitwood Energy, and Mike MacFarland of Energy Docs in Redding, California, all have tantalizing evidence that home energy savings are not hocus-pocus.Parker analyzed a ton of data from Home Energy Saver and found that slightly deeper operational energy audits that included a thorough homeowner interview were accurate within about 1.5% on actual usage, where even a standard energy audit (labeled “Asset::Full” in the table below) was still off substantially. (See 32:30 in this video.) Parker found through analysis of Home Energy Saver data that consumption is very predictable, Chitwood found that more comprehensive jobs result in surprising societal benefits, and MacFarland is confident enough in his work he guarantees crazy low energy usage. Does this make them DaVinci, Galileo, and Columbus?As discussed in my blog about low-hanging fruit, significant energy savings are not likely to occur until adequate control over heat, air, and moisture flows in a home is achieved. Until then, large variations in results are likely. This lines up with Chitwood and MacFarland’s experience as well.Accuracy and precision can be had in the home performance industry. We need to incentivize larger jobs that get us to the point where good results are likely. HVAC upgrades and building enclosure upgrades need to be planned for, and preferably happen, simultaneously. I am not the only one to argue for simultaneous instead of staged upgrades, Dan Kartzman of PowerSmith does a great job here. The key aspects of the programSo without further ado, here are the key aspects to my proposed One Knob program.One Knob = negawatts. One simple adjustment. One easily interpreted market signal. No management from above, no program tweaks: just adjust the volume of the negawatt incentive. Just pay for saved energy in negative watts, or negawatts. Raise and lower as needed, just like the volume knob in your car.A focus on results. Excellence, accuracy, and savings are all incentivized, which means they are likely to occur. These do not truly exist now, except via false proxies. The proposed “One Knob” program would deliver the desired results.Pay for projected savings. If 10,000 kilowatt-hours are projected to be saved, and the rebate is $.40 per kWh saved, then the homeowner gets a check for $4,000. Convert savings from all fuels to kilowatt-hours, meaning negawatts.A prompt rebate process. After the project is completed, the homeowner rebate is paid. Once per year, contractor ratings are updated and published. Updates could be continuous with the “Energy Savvy” platform.Accountability. Contractors have the most control over results, so let them make the energy savings projections. Let them choose the software. Let them choose the measures. It makes kitchen table transactions much simpler.Publish contractor metrics and rank them. HPXML will collect the needed data, and the industry is moving that way. Promote the rankings so contractors can use them to build trust and confidence at the kitchen table. Excellence becomes its own reward and failure becomes a public badge of incompetence. Data is critical.Build intellectual capital. By giving contractors authority for design and accountability for results, you create an intensely competitive environment where huge gains in workforce talent occur.Leverage desire for better homes. Homeowners will make large investments to fix problems. Good incentive design can harvest energy savings from these improvements at the savings value. One Knob’s simplicity allows and encourages scale. Focus on comfort, health, and safety messages, not energy savings.Win-Win-Win. Homeowners get problems solved, contractors make a living, and the other parties get the cost-effective energy savings they need (without puffery). One Knob aligns interests.Not punitive. Humans react far better to positive than negative reinforcement. Multiple ranking metrics can be promoted: good air sealing, good realization rates, highest energy savings, best energy savings per dollar spent, etc. Everyone is likely to have something good to point at. Still, since no one wants to rank on the bottom, it’s an incentive to do well.Breeds mutual respect. Contractors are not treated like children, as is often the case now. All parties act as equal partners working towards common goals.Fuel-agnostic. Small changes crush contractors; they need one track to follow. No crazy rules about fuel switching, or different “incentives” for different fuels like electricity, propane, or natural gas. Just pay for energy savings in negawatts. An “energy bank” could create a buffer to perversity introduced by funding sources.Nothing new is needed. Except accountability and a transparent results ranking system. Today’s contractors, employees, software, equipment, etc. will all work with One Knob.Future financing. Financial markets need some certainty of savings showing up to offer low rates. One Knob will provide this data and ever improving certainty. One Knob rewards accuracy and precision in a space where accuracy and precision have never been an objective. Market transformation is far easier once low-cost financing that stays with the house, i.e. “on-bill” financing, is available.Align interests and incentives. Homeowners, contractors, programs, utilities, and PUCs all have different objectives, but can be pulling in the same direction. One Knob achieves this. No perverse incentives.Substantially less administration. If market transformation is to occur, there is no way that current administrative systems can scale with it. High ranked contractors will get automatic job approval (remember, their results will still be ranked, so they still can’t skimp) leading to less administrative work for both contractors and the program. One Knob is scalable, and more effectively puts ratepayer funds back in ratepayer hands. How can a program be fuel-agnostic?In order for One Knob to work, it must be fuel-agnostic. Designers must stay client-focused. The client is the homeowner, not the program. Designers must develop a practice that focuses on best results for the client and not be enticed away by changing incentives. There is mounting evidence in New York that fuel bias has significantly harmed homeowners who participated in the program by shifting them from electric to propane instead of to heat pumps. (Heat pumps are not an “approved measure.”) In California, if a client switches from gas and electric to electric-only, they likely don’t qualify for a number of rebates.It’s vitally important that programs that adopt the One Knob approach are completely agnostic to methods, materials, and fuels, so that energy efficiency remains a primary objective. The only thing that matters is results.Programs often have shifting funding sources. They may get money for electric savings; then later, they may get money for oil savings. To be fuel-agnostic may require an “energy bank” where energy savings for every job, regardless of fuel source, are banked then sold as efficiency purchasers show up. A PUC could buy a gigawatt of negawatts from a utility. The utility receives credit for their goals, and then the PUC can sell those savings for whatever fuel is saved: propane, electricity, natural gas, fuel oil, etc.In New York this might be relatively simple, since NYSERDA receives money from all utilities and other sources such as RGGI. There is already a central pot. For other states with limited funding, this might be more challenging. Aren’t accuracy and precision impossible for home performance?

first_imgThe long-term water supply projects in Rajasthan will be completed on time to ensure the availability of water in the geographically difficult areas. Chief Minister Ashok Gehlot has given instructions for speeding up implementation of water supply schemes for both drinking and irrigation.Mr. Gehlot said at a review meeting here after the appointment of committees for the Rajiv Gandhi Jal Sanchay Yojana that the long-term projects would permanently resolve the issue of paucity of water caused by scanty and erratic rainfall in the State. “The projects should be formulated to meet the local needs and regularly monitored,” he said.The progress of projects financed by institutions such as the National Bank for Agriculture and Rural Development, Japan International Cooperation Agency and New Development Bank as well as the dam, canal and small irrigation projects was reviewed on the occasion.The committees appointed at the district, block and village panchayat levels for the Yojana will coordinate the activities of various departments and monitor the progress of work for water conservation.last_img read more

first_imgThe Delhi Metro was the choice of Delhiites trying to reach the Jawaharlal Nehru stadium for the closing ceremony of the Commonwealth Games on Thursday.The Delhi Metro Rail Corporation was responsible for ferrying more than 70 per cent of the total number of spectators. According to official Metro ridership figures, 45,000 people used the Metro to reach the stadium. On Thursday, the Jawaharlal Nehru stadium, Jangpura and Jorbagh Metro stations recorded a total ridership of 45,000 people.The stadium’s Metro station recorded the maximum ridership of 22,000 spectators while 18,000 and 5,000 commuters used the Jangpura and Jorbagh stations respectively. Unlike the day of the opening ceremony, the glitches on the Metro lines were minimal on Thursday. An equal number of people used these stations for getting back to their homes after the closing ceremony.The Delhi Metro had made elaborate arrangements to handle this rush with full support from the Central Industrial Security Force and the Delhi Police. Officials said they ran trains at an all-time high frequency of less than two minutes on the Central Secretariat-Sarita Vihar (Line-6) section.last_img read more
