The Cost in Human Energy

Guest Post by Willis Eschenbach

For a while, I taught a course in human-powered machinery for the Peace Corps. You know, bicycle powered generators, treadle powered pumps, that kind of thing. One of the very rough rules of thumb regarding human energy is that an adult human can put out about a hundred watts on an ongoing, constant all-day basis. If you were to hook up a bicycle to a generator you could generate a kilowatt-hour every day … if you were in good shape and you put in a ten-hour day. Sounds like work to me.

I got to thinking about this number, one kilowatt-hour’s worth of electricity for a long ten-hour day’s work, in the context of the discussion about energy costs. Some people think raising energy costs to discourage CO2 production is a good thing. I say that raising energy costs, whether to discourage CO2 or for any other reason, trades a certain present loss for a very doubtful future gain. As such, it is an extremely bad idea. Here’s why:

The existence of electricity is perhaps the one thing most emblematic of human development. With electricity, we get refrigeration to preserve medicines and foods, light to extend the day, electric heat, power to run machinery, the list goes on and on. Now, as I showed above, we can hire somebody to generate electricity for us, at the rate of a kilowatt-hour for each ten-hour day’s work. Where I live, this day’s worth of slave labor, this thousand watt-hours of energy, costs me the princely sum of about thirteen cents US. I can buy an electric slave-day of work for thirteen cents.

That is why I live well. Instead of having slaves as the Romans had, I can buy a day’s worth of a slave’s constant labor for thirteen measly cents. That is what development consists of, the use of electricity and other forms of inexpensive energy in addition to and in lieu of human energy.

Now, here’s the next part of the puzzle. Out at the farther edges of society, where people live on a dollar a day or less, electricity is much more expensive than it is where I live. In the Solomon Islands, where I lived before returning to the US in 2009, electricity in the capital city cost fifty-two cents a kilowatt-hour, and more out in the outer islands.

Now, let us consider the human cost of the kind of “cap-and trade” or “carbon tax” or Kyoto Protocol agreements. All of these attempts to decrease CO2 have the same effect. They raise the cost of energy, whether in the form of electricity or liquid fuels. But the weight of that change doesn’t fall on folks like me. Oh, I feel it alright. But for someone making say $26.00 per hour, they can buy two hundred slave-days of work with an hour’s wages. (Twenty-six dollars an hour divided by thirteen cents per kWh.). Two hundred days of someone working hard for ten hours a day, that’s the energy of more than six months of someone’s constant work … and I can buy that with one hour’s wages.

At the other end of the scale, consider someone making a dollar a day, usually a ten-hour day. That’s about ten cents an hour, in a place where energy may well cost fifty-two cents per kilowatt-hour. Energy costs loom huge for them even now. I can buy six months of slave labor for one hour of my wage.  They can buy a couple of hours of slave labor, not days or months but hours, of slave labor for each hour of their work.

And as a result, an increase in energy costs that is fairly small to me is huge to the poor. Any kind of tax on energy, indeed any policy that raises the cost of energy, is one of the most regressive taxes known to man. It crushes those at the lowest end of the scale, and the worst part is, there is no relief at the bottom. You know how with income tax, if you make below a certain limit, you pay no tax at all? If you are below the threshold, you are exempt from income tax.

But energy price increases such as carbon taxes don’t even have that relief. They hit harder the further you go down the economic ladder, all the way down to rock bottom, hitting the very poorest the hardest of all.

So when James Hansen gets all mealy-mouthed about his poor grandkids’ world in fifty years, boo-boo, it just makes me shake my head in amazement. His policies have already led to an increase in something I never heard of when I was a kid, “fuel poverty”. This is where the anti-human pseudo-green energy policies advocated by Hansen and others have driven the price of fuel so high that people who weren’t poor before, now cannot heat their homes in winter … it’s shockingly common in Britain, for example.

In other words, when James Hansen is coming on all weepy-eyed about what might possibly happen to his poor grandchildren fifty years from now, he is so focused on the future that he overlooks the ugly present-day results of his policies, among them the grandparents shivering in houses that they can no longer afford to heat …

Perhaps some folks are willing to trade a certain, actually occurring, measurable present harm to their grandparents, in order to have a chance of avoiding a far-from-certain distant possible future harm to their grandkids.

Not me.

I say let’s keep the old geezers warm right now, what the heck, they’ve been good to us, mostly, and lets provide inexpensive energy to the world, and thus encourage industry and agriculture to feed and clothe people, and let the grandkids deal with the dang future. That’s what our own grandparents did. They didn’t dick around trying to figure out the problems that we would face today. They faced the problems of their day.

Besides, according to the IPCC, fifty years from now those buggers are going to be several times wealthier than we are now. So why should I be worried about Hansen’s and my  likely wealthy grandkids in preference to today’s demonstrably poor children? My grandkids will do just fine. Heck, they’ll probably have the dang flying cars I was promised, and the fusion power I was supposed to get that would be too cheap to meter, so let them deal with it. We have plenty of problems worrying about today’s poor, let’s focus on that and let the future take care of their poor.

The real irony is that these folks like Hansen claim to be acting on behalf of the poor, in that they claim that the effects of global warming will hit the poor hardest. I have never found out how that is supposed to happen. I say this because the effects of global warming are supposed to hit the hardest in the extra-tropics, in the winter, in the night-time. I have a hard time believing that some homeless person sleeping on the sidewalk in New York City in December is going to be cursing the fact that the frozen winter midnights are a degree warmer … so exactly which poor are they supposed to be saving, and from what?

Too funny/weird. I guess, if you don’t listen to yourself the opinion of others matters not.
Thanks, again Willis. The ‘Greens’ are willfully ignorant about population, sustainability and resources. Why we should believe they have a grasp on anything except purse strings is beyond me. I cannot think of a single thing they got right. Ever.

The only nit I would pick is on shaking one’s head in amazement at James Hansen. We’re well beyond that. The death toll per penny of carbon tax needs to be calculated and laid at his feet and the rest of the people who advocate such global energy taxes.

@MorningGuy:
Did you add in the cost of the invertors, batteries and installation? I think you will find the payback, without subsidy, to be considerably longer!
BUT if you can make it work for you without stealing tax subsidy from your neighbors to make it work, more power to you (pun sort of intended).

Having also lived long term in so called third world countries I have realized very clearly, and commented very often on this one thing: If you double the cost of food for a man who spends all of his money on food, he and his family simply get to eat less….
Glaringly obvious, but apparently not significant to some. And we could elaborate on that by discussing energy …
But Willis has already done that above, and done it so much better that my one liners, in his measured, story telling style.

Willis: “But energy price increases such as carbon taxes don’t even have that relief. They hit harder the further you go down the economic ladder, all the way down to rock bottom, hitting the very poorest the hardest of all.”
Let us assume here in the US consumption of gasoline is at approximately 140,000,000,000 gallons per year. The price has gone up substantially since 2008 to the tune of additionally costing the cunsumer approximately $500,000,000,000. That equates to fewer revenue to other non essential items and essential items e.g. food, clothing, etc. The standard of living declines rapidly for the unemployed and those on a fixed income who are driven even further into poverty just by the increase in fuel.
Now we have a marxist government “necessarily” taking the cost of energy up with a policy of putting coal and other inexpensive power generation out of business with no regard to the quality of life for the average American. So the consequence of higher energy costs is higher everything else costs. The entire country is headed toward the likes of Detriot, a waste land of poverty, while Stalinist Obama vacations on your nickle. No sacrifice for him and his DC cronies.

The converse is in developing countries, huge megaprojects aren’t sustainable or needed. The classic example is water. You can drill a well for a few thousand dollars, put a simple (human powered pump, easy to repair), and everyone in the area can get clean water and so waterborne diseases stop. These poor villages could not afford electricity for a penny per kilowatt. Getting them on the economic ladder is an issue that needs addressing, but what is available and affordable in a big city in the USA is not the same thing in the far reaches of the Congo. An advanced, highly networked economy is different from one still near subsistence. So the solutions and fixes, charitable or via trade have to be appropriate. And the free market can most easily address it.
Instead, the only “Aid” we want to provide is to have the country go into debt (issue sovereign bonds) to pay for a billion dollar waterworks built by one of our multinational megacorps that won’t even reach the impoverished areas, but will pay the ruling elite for presiding over the complex machinery. Then when they can’t pay the bonds, we impose “austerity” which means starvation in poor countries. And we send crony bureaucrats to manage things. Our solution to their starving children is to send condoms. Our solution to people dying of infections is to send contraceptives.
The situation in Greece is ironic, but it is also payback.
The beauty of a real market is it will allocate scarce resources. The evil of regulation is that it makes abundant resources artificially scarce, whether through simply taxing them into unaffordability, or creating artificial barriers to entry.

Perhaps the most ironic aspect of CAGW theory (or should I say theology) is that at its core, it has nothing to do with “saving the planet”, but rather it’s a simple ruse for governments to control and micro-manage industry, collect huge carbon taxes, implement global wealth redistribution, restrict economic growth and industrialization of impoverished countries.
The technology of Liquid Fuoride Thorium Reactors (LFTRs) exists where zero CO2 emissions are possible at an electricity production cost of less than $0.01/kWh (solar/wind is around $.30/kWh)
In addition, the residual heat from the gas turbine generators could be used to desalinate sea water, produce limitless supplies of NH4, CH4, H2, diesel/aviation fuel, or any hydrocarbon desired for next to nothing.
The only things holding back this technology are government rules, regulations, licensing procedures and formal approval to build them. The government wouldn’t even need to provide the research and development funds as the private sector would readily invest a few $billion to get LFTRs built and patent the technology that’ll make them $trillions in the future.
Thorium is a very abundant element. An average-sized rare-earth mine disposes of 5,000 MT/yr of reactor-grade Thorium232 while processing neodymium, which is enough to supply the entire world’s energy needs…for a year… It’s not like we’ll ever run out of this stuff…
The Chinese are now in the early stages of LFTR development and the world will most likely be buying reactors from them in the near future.
And so it goes….until it doesn’t….

ever heard of solar panels???
you can pick up a 200W solar panel now for about $200, will generate about a 1kWh.
here in Oz 1kWh costs ~30cents – $200/30cents = ~700 days payback time, makes sense to me …
no punt intended ;P

I agree, but the economics are different here. 5 kW peak — note well, peak — costs around $11K installed — the solar cells are a bit more costly retail, and you need inverters and some electrical work done in order to be able to automatically sell daytime surplus back into the grid in lieu of hard storage (installing hard storage — a big pile of batteries — adds substantially to the cost and shortens the lifetime as batteries have to be replaced at least once or twice a decade). Also, electricity is cheaper — even in California — than $0.30 USD/kW-h. A 5 kW peak rooftop would probably be lucky to make an average of 30 kW-h per day, call it $3 (although it might be as high as $4 or $5 or as low as $2) recovered cost. 365 x 3 = $1095/year, and 11000/1095 = 10 years EXCEPT that you have to borrow the money to buy it at (say) 5% annually, compounded monthly. This produces a serious problem, as your “annual profit” has to be reduced by the cost of the borrowed money (this is part of a serious CBA, sorry). So you really only pay off at the rate of $1.50/day the first year — the other $1.50 goes to servicing the debt.
After a bit of fairly serious work with a compound interest calculator with a $90/month fixed payment, it takes roughly 14 years to pay back the loan. Then, of course, it is worth $90/month to you for the next 6 to 11 years to reach the expected 20-25 year lifetime of the hardware, less any maintenance costs along the way.
In Oz, a fair estimate might cut the amortization time in half — or it could stretch it out. I’m assuming very favorable (basically new construction/mortgage) financing, not short term/consumer interest which would cost at least 2-3 points more and drop your paydown period to “forever”, you’d probably barely break even on the cost of the solar collector over its entire lifetime. OTOH, if you have $11K in cash lying around, a return of $1000/year is way better than almost any mundane investment. Indeed, your biggest problem would be finding something to do with the $1000 that would come close to “compounding” the interest, since there AREN’T any other 10%/year investments one can easily make with the money.
The point being that in the US, solar panels “make sense now” only in high-insolation parts of the country (the relatively arid Southwest) where 5 kW peak might generate 4 kW average instead of 3 kW average over a presumed 10 hour day that also have expensive conventional electricity, where the amortization period for a consumer-level investment is dropped under 10 years. It is already a win for commercial generation in these places — they have higher operational overhead but they also get bulk prices and cheaper money even losing half of the return to overhead and maintenance a 5% ROI is pretty attractive, with good prospects for that to go higher.
Where I live, 14 years is still too damn long. If solar panels, inverters, installation drop one more factor of two in price (or anything close to this — say 5 kW for $7000 or $8000) that would drop the amortization to 10 years, followed by a ROI of $1000/year for 10 to 15 years (which means slightly less than this “forever” if one uses some fraction of the income to rollover replace parts as they wear out or fail). At that point installing built in solar electricity is a no-brainer for new construction — it makes the house much more attractive if you can sell it with “free air conditioning for life” as part of the price (this is more or less what one would be buying, and in the southeast that’s a big deal). Retrofitting old construction would also make sense, but of course it does require owners with the means to borrow the money and service the debt (or pop the money out of savings to buy the higher rate of return).
I predict that we’ll easily reach this sort of pricing by the end of the decade. Willis and others disagree, and all we can do is wait and found out. This is one of many reasons I think that even if there is some truth to the CAGW claims — say truth at the level likely to be stated as the AR5 conclusion, roughly 2.5 K warming by the end of the 21st century (some 0.3 to 0.4 of which has already occurred) then sheer economic choices are rather likely to reduce our consumption of carbon based fuels by the middle of the century well below projected worst case rates, and by the end of the century carbon dioxide concentrations could be coming down, not going up, especially if there is (by then) any evidence of true “catastrophic” sustained warming.
In other words, no reason to panic and little reason to dump huge amounts of money into arcane carbon trading schemes that have no effect except to make all of the brokers in the world rich(er) and provide a flexible and potent instrument for laundering money. Good reasons to continue to support research into solar technologies and to help support the market in ways that will eventually lead to economies of scale here.
I’m certain that it is sacrilege to even suggest what I’m about to suggest, but I still think it is worth kicking out onto the table. Electricity is the fundamental resource, the essential driver of civilized economies and standard of living. Everybody hates paying taxes. Fighting wars over scarce energy resources sucks, and the vast wealth associated with the multinationals that provide them creates “shadow governments” with an income greater than that of many small countries and a disproportionate political influence. We could do a lot worse than to create a national solar electrical project and invest (say) $100 billion/year in massive solar construction for the next decade or three, buying a TW or so of capacity every five years at likely scaled costs. Make the joule the fundamental basis of our currency, and use the income from selling joules to fund the government, eventually buying additional capacity strictly out of income and using the surplus to reduce taxes.
By 2050 we might well have eliminated the federal income tax, money could have a solid international foundation for the first time since we went off the precious metal standards, carbon usage would be substantially decreased and possibly even equilibrated. Sure, the government often sucks at running “businesses”, but it could be done by setting up a federal trust or something. The biggest risk is that somebody would come along and invent fusion and obsolete the whole thing, but even that could be managed with a buyout of fusion and indeed would make the whole idea even more stable and productive. The “tax” of buying energy would be perfectly balanced, neither progressive nor regressive. Live off the grid, pay no federal taxes directly, but of course you pay them any time you buy an object manufactured with energy. Live on the grid, the better your lifestyle the more you spend on energy the higher your de facto taxes.
Wait, let me put on my flameproof suit. I’m walking down into my concrete bunker. Putting on my flash goggles. OK, now. Bring it.

Willis, you are right. Before getting all worked up about the future of “our children”, shouldn’t we rather worry about all the children who live right now and have no access to affordable energy and its benefits.
Save them now before caring about the conditions of living in the future.
Man-made social unrests, man-made wars or natural catastrophes, such as volcanoes, meteorites, hurricanes or tsunamis are as unforeseeable as future weather conditions but are within the realm of probability.

Willis,
Have you considered having the unfit and overweight being required to exercise, and having their stationary bikes wired to a generator? Two problems with one stone.
Of course, we’d have to keep this people under strict control to keep them from overeating or consuming foods not on the First Lady’s approved foods list. Think of all the savings in food and greenhouse emissions.
Of course, if people do succeed in getting fitter and thinner, we won’t have enough obese or overweight people to chain to bicycles. Then it will have to become mandatory for all.

You are spot on. Recall that in the early 1970’s the nuclear industry was talking a nuclear energy device for every household. Who needs a grid if we all have a house sized nuclear plant parked next to the garage, or powering individual industries. No loss of energy through transmission lines. No rolling brown outs or other devasting power outages.

Bang on the nail as always Willis – thank you.
Here in the UK they are still enthralled with the idea of windmills, although the penny is beginning to drop – it is doing it very slowly and with much infighting within the coalition government. When your Prime Minster’s Daddy-in-Law is getting a subsidy of £1k a week off his windmills….. fill in your own ending.
What amazes me is the dirth of good engineering advice given to UK government. It is fact that out of 650 Members of Parliament only 3 have an engineering or science qualification.
Why don’t they listen to an engineer like Prof. Colin McInnes. A year ago he wrote this piece for the Royal Academy of Engineering’s online magazine.

The cost to really poor people in poor countries for electricity is $50 per kWh if it comes in the form dry cell batteries. It has remained at that level for more than 35 years, I have observed. Batteries are sold for that historical cost.
LazyTeenager says:
>Sounds too simplistic to me….
>2. But in poor countries the wholesale cost is just a small proportion of the total, so any additional due too carbon tax will have little impact.
Lazy, just who is being simplistic??? Good grief it is clear you have never lived in a Third World country!
Electriciy, the magical fruit, the annointed energy carrier, the golden goal of development enthusiasts, the crystal skull of wealth-bringing treasure hunters, is only affordable at the margins in the LDC’s and when the have it, they don’t cook with it (for example). Many off-grid people are dependent on the few with electricity for paid services and any rise in cost disproportionately and negatively affects those clinging to the margins. A carbon tax is insane because nearly all energy used by the poorest 3 billion people on Earth is carbon-based biomass. If anyone thinks biomass will be exempted, read the UNFCCC rules for calculating the sustainablility of the biomass fuel supply.
I agree that solar panels http://click.email.globalspec.com/?qs=fa4fcf0ebfc24ed9abc55feda058db068d2b0b031a83719c635fbeb218901ea3ab24b37ebf115f38 have a strong future as do thermo-electric and thermo-acoustic generators. The poor can actually benefit from greater access to independent power generation. If it were accessible without subsidy, it would bring real benefits because it can reach sustainable expansion. What is wonderful is that LDC’s are developing the capacity to do this without reference to the technology-developed overlord wannabes. The idea that subsidising ‘renewables’ carte blanche until they ‘become sustainable’ is a bucket of puke.

January 2, 2013 7:54 am

Excellent essay, Willis.
I imagine what the governments will try to do is create a new “fuel assistance” to allow the poor to avoid “fuel poverty.” This will create all sorts of government jobs and paperwork, which they like.
When I was younger I raised five kids doing landscaping and odd jobs, and jobs were few and far between during the winter. (Often I’d work in a factory for a couple months.) One time I actually got in line for fuel assistance. After being sent from office to office, and standing in line after line, I was told I needed written proof from my employer that I wasn’t currently working. When I explained I was a landscaper and handiman, I was told that, as I had multiple bosses, I had to go to each and every person I had worked for, and get a paper stating I wasn’t currently working.
After a few choice words I went and cut wood in the woods. I found that, in the time it would have taken to fill out all the paperwork I, A.) Got enough wood to heat my house; B.) Got lots of fresh air and excersize; C.) Regained my sense of self-esteem and D,) Began a period when I went fifteen years without turning on my propane heater.

I assume you mean that the huge investments already made are insufficient and/or so ill-directed that Obama in his superior scientific insight should take our money, gaze into the middle distance, and direct its use more efficiently. Gee, what could go wrong with that?

January 2, 2013 7:57 am

The notion that an additional 100 ppm or so, of an atmospheric trace gas fundamental to organic life on this planet, was shaping up to extinguish life as we know it, always struck me as beyond absurd. As a ‘climate science’ layman however, I was prepared to give some credence to what seemed a well-founded concensus that this might indeed be the case – Until Climategate 1 that is. Since then and with the help articles like this I have begun to understand what is realy going on here.
It seems to me that there are two related and overwhelmingly powerful reasons why Western Establishments continue to pay at least lip service to the IPCC ‘Catastrophic CO2 driven climate change’ boondoggle and they have nothing whatever to do with the alleged danger posed by man made CO2 emmissions:
1. Carbon trading is set to become the biggest derivatives market ever, with all that means for the Western dominated globalised financial services industry. What politician seeking the approval of his biggest paymasters is going to risk upsetting that little apple-cart?
2. The REAL but hidden and unacknowledged problem – the implications of an inexorable and irreversible decline in fossil fuel EROEI. In face of that little doozy, governments of all persuasions are happy that the mass of humanity should view their ‘carbon footprint’ much like mortal sin to a good Christian. That way they will then be much more ready to accept the measures deemed necessary to deal with the REAL problem, as physical reality forces the issue.
Thus, just about everyone involved in Energy/Climate ‘Policy’ has an interest in keeping the gravy train in motion – pesky sceptics with superior science to the contrary notwithstanding.
