2000-Watt Society

I wasn't going to read Elizabeth Kolbert's "New Yorker" piece on the Danish island of Samsø because I'd covered it already and because I heard her talk on the radio;  but a friend sent me a copy and I found that the second half of the article was all about the 2,000-Watt Society, a very interesting idea and a concept I'd been looking for.

2,000 Watts per person per year (or 17,520 kWh) is what we produce now.  It is a baseline for sustainability, at least, this is what the scientists of the Swiss Federal Institute of Technology believe.  This 2,000 Watts includes all activities - working, eating, traveling, and investment in common infrastructure.  Currently, Switzerland is a 5,000 Watt society and most other Western European countries are 6,000 Watt societies.  The USA and Canada consume 12,000 Watts per person per year.

"At first glance, the objective of a 2,000-watt society appears unrealistic, but the necessary technology already exists,"  says Moritz Leuenberger, head of the Swiss Federal Department of the Environment, Transport, Energy, and Communications.


A 2004 paper [pdf alert] on the feasibility of the 2,000-Watt Society concludes that currently available technology can make buildings 80% more efficient, cars 50% more efficient, and motors 25% more efficient.  I think that people like Ed Mazria* and Amory Lovins would certainly agree.  

In the envisioned 2000-watt society, the quality of life will not suffer at all. On the contrary, aspects such as safety and health, comfort and the development of the individual will in fact improve, and income is expected to rise by around 60 percent over the next fifty years.

Recently, I heard Greg Watson, former director of New Alchemy Institute and now a senior energy advisor to Governor Deval Patrick of the Commonwealth of Massachusetts (may G*d preserve her), talk about New Alchemy's 1980 renovation of an old barn into an auditorium and office space.  They had insulated the building so well that only body heat and the waste heat from the necessary appliances were enough to keep the building comfortable.  He called it a zero carbon building using 1980 technology and, when they presented their results to local architects, they were met with almost total disbelief, "How can you heat a building without a furnace?!!!"  I can remember reading a newspaper report about a similar model energy building built in Denmark around 1976 where they had to open all the windows and doors on the night of the opening party because the heat generated by the crowd of people was excessive.  I am sure that both the New Alchemy and Danish buildings had air-to-air heat exchangers to make sure that the indoor air quality was healthy.  We could build these buildings in the 1970s and the 1980s and yet are still not building the majority of our buildings this way in the early  21st century, the decade I call the Uh-ohs (for obvious reasons).  

My own observation, since the 1970s, is that the energy problem has never been a technological problem but a human problem, a problem of vision and will.  What I like about the 2,000-Watt Society is that it gives us a target for an equitable and sustainable, if not restorative, economy.  

My focus has been primarily on survival solar, essential solar, refugee camp solar, solar as civil defense - flashlight, radio or cell phone, extra set of batteries - because I know that scale of renewables is affordable and available now.  Solar IS Civil Defense, I keep on saying (and said to Greg Watson and the staff of my local Congresscritter within the last few weeks).  This is my baseline for the world economy and an improvement in the standard of living for a billion or two of the people who now live on this Earth.  Provide everyone with these things and we have a renewable foundation on which we can build a restorative economy.

2,000-Watts per person per year, equally distributed, is the next step up in that economy.  Within that measure, people all around the world can live full and productive lives of relative comfort, approach a standard of living that the Swiss enjoyed as recently as 1960, not exactly a subsistence era.  Back in the early 1990s, the Dutch Friends of the Earth produced a study which looked at equity and sustainability in a similar way.  They broke down the fair share of all the goods and services available per person per year within a sustainable framework.  My understanding is that this book had quite an effect in Europe but I have never been able to get my hands on a copy to see in detail what their sustainable fair share actually was.  The only nugget I remember is that everyone could have access to one three thousand mile plane flight once every five years, if we were committed to equity and sustainability.  That is what strict justice and the world ecology could provide.

Counting up my own gas and electric use over the past year, I use 2250 kWh, leaving 15,270 kWh to provide for my food, clothing, entertainment, transport (I use bike, foot, public transit, and took one long distance flight), as well as my share of the common infrastructure (roads, water, sewage, and the like).  The Swiss calculate that the individual share of infrastructure amounts to 900 Watts.  If the same ratios apply between their energy use and ours, my share is 3600 Watts or 31,536 kWh right there.  So, I use 33,786 kWh or 3856.85 Watts per year just counting my gas, electricity, and share of our infrastructure.  [My numbers may be off as I am not an engineer, mathematician, or statistician.  Please feel free to correct me if I am wrong.  I do vouch for the gas and electric figure of 2250 kWh but could have gone haywire anywhere along the line from there.]

But now, at least, I have a target.

 title=

The canton of Basel-Stadt is a pilot program for the 2,000-Watt Society.  They have been working towards that goal since 2001, concentrating on transportation and urban development.  The general outlines of the Swiss approach is Smarter Living and is as rigorous as one would expect [pdf alert].  Their timeframe is to reach this goal by 2050, halving their carbon emissions in the process.  Personally, I think 2050 is too late and halving carbon emissions is too little.  I agree with Dr James Hansen and Bill McKibben that we have to reach 350 ppm of carbon dioxide and do it as quickly as possible.  Of course, 350 ppm CO2 is only short-hand for all the greenhouse gases we put into the atmosphere.  It may be that managing methane and NF3 will be quicker and more effective than concentrating completely on only atmospheric carbon.

The thought experiment of a 2,000-Watt Society is a bracing one but an extremely useful exercise.  Thank you, Sally, for sending me the article.  You helped me find a piece of the puzzle that I'd been missing.  Now I have to do the hard work of improving my practice to live within those limits, 2000 Watts, my fair share of the energy wealth of this Earth.

Ahh, the search engine still is not my friend. :-( Haven't we discussed this concept some time ago? Maybe it would be interesting to look at that discussion again too.

I knew about the concept of the 2000-Watt-society, however, I was not aware that I live in a city that has a pilot program. Guess they need to improve their PR.

And thanks gmoke, very interesting diary. Leuenberger is really an asset to the Swiss government.

I've been looking for something like this article, too - a good starting point for a data-based  discussion of sustainability.

Unfortunately, since my house is all-electric, I use up 2/3rds of my allotment right there. I need a couple more people to move in to reduce the per-person rate. Either that, or sell to a family and build something more suitable to a couple.

One thing that occurs to me immediately - does anyone have statistics at-hand concerning the proportion of energy used by industry (writ large) vs. residences?

If you can live in less space than you are using ... why not move out of those rooms and close them up in the middle of the winter and/or summer (whichever is the high watt season for your part of the world)?

2000 W/yr isn't the same as 17520 kWh pr year. 2000 W is the same as 17520 kWh/year. W is power, which is energy per time, so W/yr would make energy per time squared. While Wh/yr is power times time per time, which is power. So I believe you'll want it to be 2000 W, full stop, instead of 2000 W per year.

It just irks me, like it does when I see someone refer to the speed of a ship in "knots pr. hour" or to a windmill producing mWh...

The physical units involved here are the Watt and the Watt-hour. Unfortunately these particular units can seem a bit confusing at first.

The Watt is a unit of power. Power is defined as the rate of flow of energy, that is, energy transferred per unit time.

The Watt-hour is a unit of energy. 1 Watt-hour is the total energy used when 1 Watt of power is continuously transferred for 1 hour.

The proposal under discussion is that each person should use (on average) no more than 2000 Watts.

2000 Watts is the power required to keep twenty light bulbs illuminated, if each bulb uses 100 Watts. So you could exactly meet the proposed requirement by keeping those twenty 100-watt light bulbs illuminated at all times, day and night.

Now that we know the permitted power, we can calculate the total energy you are allowed to use each day, or each month, or each year.

If you leave your twenty 100-Watt light bulbs turned on for 1 hour, the total amount of energy you have used is 2000 Watts times 1 hour, or 2000 Watt-hours.

Over the course of one day, those always-lit bulbs would use 2000 Watts times 24 hours for a total of 48,000 watt-hours per day.

Over the course of one month, your light bulbs would consume 2000 Watts * 24 hours * 30 days, for a total of 1,440,000 watt-hours per month.

Over the course of one year, the bulbs would use a total of 2000 Watts * 24 hours * 365 days, for a total of 17,520,000 watt-hours per year.

The above figure can also be expressed as 17,520 kilowatt-hours per year.

Watts, you need to spend an hour under 2,000 Watts by the same amount in order to balance it out over the year.

The problem is, how do I get to Oz? Even though I have no car and do not eat a tremendous amount of meat, I'm thinking that, barring a trip on a tramp steamer that is heading that way anyway, a trip to Oz will blow a massive hole in my annual energy budget.

Well, for every hour you are over, you need to spend a number of hours under sufficient to balance it out. If you are over by 100 W for one hour, you could compensate by being under by 200 W for half an hour or by being under by 1 W for 100 hours.

But how many watts is an hour of flying? If I need to be at 0 watts for six months to be able to reach Oz, that would seem to put it out of reach.

Good point, BruceMcF. I guess we will just have to build a lot more ocean-going passenger vessels. With the modest energy requirements of plain vanilla ships, solar power might even prove practical to move them around.

Other alternatives for long-distance travel are not clear. I find it difficult to imagine a battery-powered aircraft that could carry more than a few passengers at a time.

Maybe at some point it will become practical to use solar or wind power to make a lot of hydrogen or methane, which might then be used to power your journey to Oz.

Whatever the technology, I don't think it will be cheap to make the trip. You may want to hitch up your horse, drive (in the old sense) to Kansas and start looking around for a cyclone.

I was just thinking this before going to sleep last night ... take a HSR to the closest sea port and take the Zeppelin across.

Of course, those HSR lines also need to be built, and come to think of it, they probably come first, since you not only can run those suckers on electricity, that is their most common power source today.

Already have the tilt train from Rockhampton to Brisbane, but inter-urban rail from Brisbane to Sydney is in a shocking state. Just not enough 3 hour routes.

H2.  Boeing (and likely Airbus) already has an H2 plane on the drawing boards.  of course in my world view, that would mean renewably produced H2.

That's the floating offshore vision of H2 production from the cover of 1975 National Geographic.

Very briefly, the theory is that highly tuned small turbines are more efficient across the equivalent large diameter rotor.  Further, they are downwind turbines, and need no yaw bearing, as the whole device is floating in a yaw bearing.  Finally, cheaper to mass produce.

This design comes from Prof. Wm E. Heronemus, former Navy Captain who was the chief designer of the Nautilus class nuclear submarine for Adm. Rickover.  And one of my mentors.  (IknowIknow, his career as "father" of windpower in the US deserves a diary.)

At my house we use about 12 kWhrs per day, or an average of 500 W. In the summer, at least.

But if solar/wind/whatever energy is so terrific, then why do we need to worry about conserving it? There's a disconnect here between "conserving stuff like oil that is irreplaceable" and "conserving stuff because hair shirts make me feel better about myself." Which are we to pursue?

by asdf on Sat Jul 26th, 2008 at 12:33:23 AM EST
Why would you want to waste energy? Would you burn a dollar just because you could afford to?

I don't think the world is anywhere near the point where it can be urged to "conserve energy". It has to reach the point where it is no longer wasting energy first.

In the same New Yorker article, Kolbert reports that the people of Samsø "merely" replaced diesel and other fossil fuels with renewable wind and biomass.  They did not do energy efficiency and conservation (although they seem to have increased their district heating capacity) and are using the same amount of energy they were using before they became renewables.

Windmills use steel, for one thing, which aside from being a limited resource is also a lot of work to make. Renewables are great, but using more renewable energy than you need just because it doesn't do any great harm is kinda like digging a hole and filling it up again. That doesn't do any harm either, in and of itself, but surely the effort and resources expended could be put to better use.

It's not like we exactly have a shortage of public infrastructure projects waiting for attention, so even in the context of counter-cyclical economic stimulus, digging holes in the ground and filling them up again makes little sense right now.

So I guess the question becomes: Which has the lower ecological impact/resource consumption/effort required: Build enough windmills to heat our present houses or insulate them properly so we don't need to heat them. My own bet would be some combination of the two.

... a sustainable, renewable source of power available to be harvested is that there is a given budget of energy available to be harvested.

Human society in aggregate cannot live sustainably over the biocapacity of the earth, and thanks to consumption of fossil fuels, we are over that limit already. So barring a spare earth or three to import resources from, we have to start thinking about ways to live within our means.

i think i know what you mean, it's a different mentality though...

if your solar water system is creating x amount of hot water on a typical sunny summer day, you encourage people to enjoy it, because the energy to power the heating is infinite, (well, good as!)

you have 200 l. at 70°, the work has been done, and it's sitting there not getting used, and there's more that's not going to be used tomorrow!

it's a bit silly, like wanting people to let their clothes dry outside instead of using dryers, cause of all that wasted energy.

it reminds me of when a solar engineer came to scope out here, and he was encouraging me to put in electric heating for the wnter.

apart from the fact that i'd just finished putting in a woodstove/radiator/hot water system together, it seemed like, heretical to think like that, lol!

he's saying ' why hassle cutting wood? it's dirty and tiring, just let the sun (and ENEL) take over!'

it just didn't wash, with all the hairshirt programming i had talked myself into feeling.

actually there was good reason for doubting this cornucopia liberalism, as during the course on PV, it emerged that for every appliance you use, even if you were creating more sum-total than you used, (supposing you had some high-wattage stuff running at night, say a heated jacuzzi for 20), the fact that you sometimes used that much, would then provide ENEL the justification to build more coal/nuke plants, so as to be able to feed your occasional need.

i hope i'm making this clear...

sigh... so there is a cogent, compelling argument not to go hog wild on consumption, even if you take the responsibility to 'create' more than you use.

unintended consequences...

Sure, the need to design for peak load is an inherent part of any energy supply system--including sustainable setups.

Suppose I have a 100% solar heated house, designed so that the interior is kept at 60 degrees in January when its -10 outside. What is the problem with keeping the interior at 70 in March?

A practical example of this case is an old-fashioned rural windmill near here. Those systems run continuously when the wind is blowing, and pump water from a shallow well. The water is stored in a round tank, maybe 400 gallons in size, open to the top so cattle can get to it. Since there's no pump or windmill shutoff, the water overflows onto the ground and makes a largish green patch amid the surrounding desert.

The system is sized so that during periods when the wind doesn't blow, enough water remains in the tank to keep the cattle happy. When the wind does blow, the lack of a sophisticated control system simply dumps the excess as waste. A reasonable fraction of the overflow, after accounting for evapotranspiration, eventually finds its way back to the well, I suppose.

Here's an aerial view of it. (If mapquest works the way I think it does.) The green patch is the grass. The brown lines radiating out to the west are the tracks made by the cattle as they approach the tank.

how does that feel to you?

isn't water another order of abundance than sunshine?
