Sign of the times. |
We live in an age of great transition. We are in the midst
of the monumental process of switching from one set of primary energy
sources —fossil fuels— to another— renewables. During this transition we will see
almost every facet of our lives altered as all sorts of substitutions are made
in a far-reaching kaleidoscope of change. In fact, this metamorphosis is
already happening in slow motion all around us. If you were to pull a Rip Van Winkle and sleep through the next ten years, you would wake up to a different world indeed.
Promises, promises. |
But where do the reindeer land? |
Let’s take natural gas first.
Natural gas to heat indoor
space will be replaced by heat pumps powered by electricity, passive solar gain
where possible, and scattered high efficiency wood stoves.
How to electrify heat. |
Heat pump technology is already mature. The only time heat
pumps have issues is in climates that have deeply cold weather, and even then a properly sized heat pump can still heat your house, just less efficiently during the coldest days. (It also helps to have your house well-sealed and insulated so it doesn’t take much energy to heat it in the first place.) The added benefit to
heat pumps is that they also cool much more efficiently than air conditioners,
reducing electricity consumption in the summer. For those who live close to a large supply of wood, high efficiency wood stoves will be
valuable—they use half the wood of older models to provide the same amount of
heat and produce 1/10 to 1/20 of the particulate matter. (Important to
asthmatics and other people who value their lungs!) This means less chopping! Less hauling! Less stacking! If you have a house that
already takes advantage of passive solar gain in the cold months, (generally through south facing
windows onto to some kind of mass that will later radiate) well then, lucky
you. Free heat!
Passive can be active. |
Natural gas to heat
water will be replaced by solar hot water, heat pump hot water heaters, or a combination of the two.
Natural gas used to
generate electricity will be replaced by wind, solar and reduced consumption
through energy efficiency.
Desert Energy |
Danish Energy |
Natural gas to make nitrogren-based
fertilizer will be replaced by wind-powered electrolytic nitrogen-based fertilizer production, as well as by compost, worms, green manure, animal manure, crop rotation and other permaculture techniques.
We don't have to starve. |
Coal and natural gas
used to generate electricity to power standard air conditioning will be
replaced by heat pumps, whole house fans, and ceiling fans that require much lower energy inputs.
Energy saver |
Coal and natural gas
used to create electricity to power second refrigerators will be replaced by
nothing.
Energy sucker |
Electricity costs will rise (or Americans will get poorer) until
it becomes too expensive to run a fifteen-year-old second refrigerator in the
garage. When all those second refrigerators go away, that will be a good
indication our energy is priced correctly because it will mean energy is no
longer cheap enough to waste.
Oil (gasoline) used
to power private vehicles will be replaced by public and private transit,
bicycles, walking, and people choosing to live closer to jobs, goods and
services.
A veritable chariot |
Already Millennials (the under 30 crowd) are giving up car ownership to live in walkable, bikeable urban areas with transit. (This is partly due to crushing student debt that has made them poorer.) Next will be retiring Boomers who all of the sudden don't "want" the hassle (and expense) of driving everywhere. Also, since Boomers are the biggest car-driving generation, as they die off, car use will die off as well. (Note: I am a tail-end boomer. I hope to be on an adult trike when I'm eighty.)
Oil (gasoline) used
to power private vehicles will be replaced by electric cars for a small
percentage of the population.
In your future? |
Note: 96,000 electric plug-in cars of one kind or another
were sold in the US in 2013. Cumulatively, the US has 170,000 electric cars on
the road. Even if plug-in electric cars sales doubled every year for the next six years (and they don’t
appear to be on that track for 2014--April year to date numbers are up only 20%
over 2013 April YTD) that would mean by 2020 we would have roughly 13 million
electric cars on the road out of a fleet of 250 million total cars. Which means
only 5% of the US vehicle fleet would be electric. Even if every American household got by with one less car (while electric car sales doubled each year) by 2020 only 10% of the vastly reduced number of cars would be electric.
Oil (gasoline or
diesel) used to power lawnmowers, chainsaws, snowblowers, leafblowers etc will
be replaced by electric version of same, or by rakes, shovels, brooms, pushmowers,
etc., or by not mowing the grass, cutting the wood, blowing the leaves and
snow, etc. Note: chopped leaves make great mulch.
Rubber meets road. |
Paved roads are hugely expensive, and right now much of them are
largely financed by the federal government, which pays for them with debt.
(The gas tax hasn't risen since 1993, but road repair prices sure have!) Coming soon, most roads/highways/freeways between towns/cities will be user-fee
funded through tolls or a vehicle mileage tax. Since local roads will be the
responsibility of cities/towns, the only ones that will be maintained are those
where population density is high enough to pay for them. On the up side, the roads will be more bouncy. (This is actually great for joggers.)
Ooh, a dome car! |
We could do this. |
Oil (diesel) used to
transport freight via trucking will be replaced by rail.
Already happening because per ton of cargo moved, rail uses
one-fifth the energy of trucking. Demand for rail freight is growing by leaps
and bounds. However, currently 40% of rail freight capacity is consumed by coal
shipments. Take coal out of the picture and there’s lots of capacity to be had.
Oil (diesel) used to
power rail will be replaced by electrified rail.
Electrify it. |
Electrified rail uses up to 2/3rds less energy than diesel
rail. (So electrified rail uses 6-7% of the energy that diesel trucking does to
move the same load.)
Oil (heating oil) used
to heat homes will be replaced by heat pumps.
This substitution has been underway for years and is almost
complete.
Oil (liquid petroleum
gases) used to create plastics will somewhat be replaced by organic packaging
materials and/or glass, metal, etc.
Plastic world. |
Oil (gasoline) used
to make drive-till-you-qualify McMansions sellable will be replaced by smaller
homes in dense, walkable neighborhoods.
Back to the future. |
Future farmland? |
Oil (diesel) used to
bus children long distances to school will be replaced by children attending
schools they can walk or bike to.
Walking school bus. |
Oil (diesel) used to
power farm equipment will be replaced by electrified farm equipment.
Oil (diesel) used to
power heavy trucks (like buses and garbage trucks) that travel under 100 miles
a day will be replaced by electric heavy trucks.
All-electric, baby. |
Oil (diesel and
gasoline) used to transport goods the last few miles to their destination will
be replaced by small electric trucks, electric vans and electric bicycles.
Speedy delivery. |
We’re already starting to see light items like pizzas, take
out, and flowers delivered by bicycle. An electric bicycle can tote 500lbs even
uphill. Freight delivered by rail will be unloaded by electric forklifts onto large
electric trucks to warehouses that will later load onto small electric delivery
trucks.
Oil (diesel) used to
transport low-value, heavy items, especially liquids like soda pop and bottled
water, will be replaced by nothing.
People will make their own soda and/or get a water filter.
The good news is locally brewed beer will become quite economic. Perhaps even
local soda fountains will spring up again.
Oil, electricity and natural gas used
to dig up, transport, and process fossil fuels will be replaced by nothing.
Energy-intensive |
How low can our EROEI ratios go? Some people believe it takes
at least 6:1 to provide enough energy surplus for civilization to work. Right
now EROEI is 6 or 7:1 for solar pv,18-20:1 for wind, and 5:1 for nuclear energy.
(EROEI is rising for solar as the technology matures.) Tar sands and fracked
tight oil both take a lot of energy to produce. Both have an EROEI around 5:1.
Oil (bunker fuel)
used to power ships will be replaced by a combination of rigid sails, solar
power, and hydrogen fuel cells.
Hydrogen shipping |
It takes more energy to produce hydrogen as a stored fuel than you get from the fuel, so a hydrogen fuel cell
is not a fuel source but rather just a big battery. But ships could load on
enough hydrogen at ports to get them across the ocean in a reasonable amount of time. As fuel costs rise,
there is also likely to be just less overseas shipping altogether as local
production of goods will outweigh labor price arbitrage between rich and poor nations.
Oil and natural gas
used to grow corn for ethanol won’t be replaced.
Oil and natural gas
used to grow corn for animal feed and soda pop mostly won’t be replaced.
Nutrition-free calories |
Oil and natural gas
used to grow grains that are turned into processed food with little or no
nutrition but that contain lots of obesity-making calories won’t be replaced.
China added a record 12GW of solar capacity in 2013. |
Coal used to create
electricity will be replaced by renewables.
This will happen even in China. The question is will it
happen quickly enough. The US can hardly pressure/negotiate with China to reduce carbon emissions if we won't agree to do so ourselves. The good news is that China finally seems to be a teensy bit concerned that the air in Beijing is thick enough to cut with a fork and knife.
As outlined for natural gas, coal to generate electricity
will be replaced in states with great sun and onshore wind first, states with
offshore wind second, and states that love their coal industry last. Already
the cost of shipping coal is higher than the cost of the coal itself for some
states in the South. The cost of delivered coal nearly doubled between 2004 and
2011, and coal-burning power plants are under pressure because of the toxic
substances and particulate matter they produce, as well as the greenhouse
gases. The big coal burning states left are: PA, IL, IN, MI, OH, WI, IA, KS,
MO, NE, ND, FL, GA, WV, AL, KY, TN, AR, OK, TX, AZ, CO, and WY. If you live in
any of these 23 states, your electricity system has a lot of change ahead of
it but the end result will be better for your lungs.
Coal, natural gas and
oil used to power waste will not be replaced.
It would, of course, be quite expensive to replace all our
current energy use with renewables over such a short time span. The good news
is that we don’t have to—we only need to replace about half, since the rest of
our energy consumption is largely waste in one form or another and much of it is easy to reduce. Admittedly
waste is in the eye of the beholder, but other countries that arguably have higher standards of living than we do already manage to use half the energy per
person as the US, showing that we have a great deal of energy fat we can burn
off without much harm.

overall
So by 2020 most people reading this article today will have a
different form of space and water heating, will not use a personal car for most
trips, will live within five miles of some kind of light or heavy rail (either
by moving or by rail extending to them), will live within three miles of a
store(s) that provide most of their provisions, and will grow some of their own
food. They will get on a plane no more than once a year, if that. Some of their
transportation will be powered by a lithium ion battery. Half will have solar
PV and/or solar hot water panels on their rooftops. Sounds like a lot of change
indeed.
Now you might be wondering, just where are we going to get
the energy and raw materials to produce all the wind turbines and solar panels
we will need? Well, first off, we have a heck of a lot of steel in the form of
cars that will soon be jettisoned by households all over the country. (250
million cars x 3000lbs steel=750 billions lbs. The US currently uses about 200
billion lbs of steel a year, one fourth of it going to cars. A 1MW wind turbine takes about 200,000 lbs of steel, or about 67 cars' worth.) It takes much
less energy to recycle steel than make it new from its component ores.
Secondly, all the money and energy that now go into producing automobiles,
trucks, jet skis, powerboats, snowmobiles, RVs, auto parts, internal combustion
engines of any kind, soda pop, ethanol and a huge percentage of pharmaceuticals
can be freed up to manufacture solar panels, wind turbines, electric bicycles,
regular bicycles, rail cars, and light rail cars. And since everyone will be
buying less new stuff for a while (relying instead on repairing what they have
or purchasing used items from local flea markets or Craigslist supplied by a
steady flow of the contents of self-storage units) less new stuff
will need to be made or transported, saving energy. Until we get through the
transition, there will likely be less consumption of luxuries, especially those that require a lot of energy. Fewer trips to
Disneyland, Europe and Las Vegas. (More camping and visiting relatives.) Less
eating out, fewer vacation homes, fewer plastic surgeries. No more spending
$1000 on a high school prom. (Holy Toledo, the average amount a high school
prom attendee spends right now is $1139!) Young people seem willing to give up
a car rather than cell phones or internet, so my guess is by hook or crook both of those will
remain fixtures of American life, although I can’t see cell phone plans continuing
to cost nearly as much as they do now.
And then there's all the money we spend on health care--close to 20% of every dollar spent in America! It is a hellacious amount of money, and all we have to show for it is a population of whom 70% are in chronic poor health. If we simply designed thirty minutes of walking into daily life and junk food disappeared, we could cut health care spending in half, people wouldn't need 2/3rds of the medical procedures, test or drugs they take, and Americans would be a great deal happier and healthier than they are today.
300K RVs=how many solar panels? |

This is insane. |
I know that most Americans (98%?) will think what I’m talking
about here is nuts. Americans will never agree to such lifestyle changes
so they simply won’t happen. Somehow someone will figure something out (!), and our energy-slurping, carbon-spewing way of life will continue blithely on. To those folks, I am an off-the-charts doomer whose negativity is at best un-American and possibly dangerous. I should stop ruminating on these matters and dose myself heavily with Xanax.
A small (<1?) percent of the population who, through examination of the data, have become fatalistic about peak oil and/or climate change will think I
am far too optimistic. From their perspective there is no way to achieve a civilization that operates within the planet’s ability to sustain us, or even if there might be, energy will run out and/or the climate will clobber us before we can develop it. These folks are certain near-term extinction, or at least total societal collapse and massive depopulation, is a done deal. Baked in the cake. Therefore it's not worth any effort to prevent what can't be prevented. Compared to these folks, I am a pie-in-the-sky rainbow and unicorn fantasist who should realize all her ideas about how to produce enough renewable energy to power a civilization are futile, perky, and annoying. But no one can be 100% certain that human beings face extinction in the next fifty years regardless of what we do now. Given the stakes--societal collapse and billions of deaths, many of people who haven't even been born yet--we all have a moral obligation to at least try to avert the worst, even if we believe the probability of success is very slight.
Happy Land. |
Me, I think there is still a path through this mess that doesn’t have to involve massive death and suffering. The
technology and resources already exist; reorganizing ourselves to make use of
them is within our reach. It won't be easy and it won't be cheap. However, it is still possible, if we get moving on it right now. As in immediately. In the end, what we face is just a transition, one
that will inevitably involve some disruption, discomfort, and change. But with
effort, intelligence, and willingness to adapt, it doesn’t have to involve
misery, calamity, and the end of civilization. No one has to die; no one has to
go cold or hungry. Will people die, will people go cold and hungry? If we
continue to obstruct, obfuscate, deny and delay, then yes, death, misery and
hunger--from 2020 until world population collapses to something under a billion
people--are pretty much guaranteed. It will be a rough, rough road we send our
children on if we take that path.
But say, instead, we don't wait until disaster strikes and it's too late. Say there's still an even chance the worst part of climate devastation can be prevented. Say we bite the bullet, roll up our sleeves,
and get to work while there's still time. We stop burning coal; we negotiate climate/trade deals with China to stop them burning coal. We cut out waste; we electrify transportation, agriculture, fertilizer production, and heating; and we use ten percent of the energy we produce each year to build out renewable energy sources. After we’re done with the transition? Then I think many things
are possible, and it could be a rewarding, exciting time to be alive. It all
depends on how we manage the next ten years.

I am pleased to see you mention that grains are mostly empty calories. Until a few months ago I would not have agreed. I grew up thinking that grains and especially whole grains, were a healthy part of our diet. Now I know that they have a lot carbohydrates that turn to glucose shortly after eating them. So that slice of bread is not that much different than a pop.
ReplyDeleteAll these carbohydrates are one factor in our obesity and diabetes epidemic. Another factor is likely our polyunsaturated vegetable oils extracted from corn, soybeans, and other seeds. I now think that a healthy diet must include animal products including saturated and monounsaturated fats.
Today we are managing to feed the world on a largely unhealthy plant based diet with it unintended consequences of epidemics of disease. So will we be able to provide a more healthy diet with more animal products in an energy constrained world? Personally, I don't see how we can do this. I suppose that we might be able to create a synthetic food that will provide all the nutrients, but I don't really want to go there (remember Solyent Green).
Hi Old Tech,
DeletePermaculturists claim that intensive permaculture farming can create 4 to 5 times the output of conventional farming.
http://growbiointensive.org/grow_main.html
However, this does require more labor, so a heck of a lot more people are likely to be involved in at least small scale farming in the future. But also note that during WWII it's estimated 40% of people's calories in the US were grown in victory gardens largely in people's yards. Again, intensive attention as a replacement for wide-scale mechanized agriculture.
As to feeding the entire world with constrained energy resources, it does sometimes feel overwhelming. I think the world would be wise to reduce population by 1% a year for the next 50 years, just by slightly reducing the number of children born. (A 1% drop per year would get the world down to about 4 billion in 50 years, a much more manageable number to feed.)
This is most easily achieved by providing education to girls and access to birth control to women. Both cost some money, but not all that much in the larger scheme of things. The harder part will be coming up with an economic system where prosperity is possible without endless growth--in people, in resource consumption, or otherwise. We will have to learn the art of the steady, sustainable state.
I too have seen reports where permaculture does work, but I suspect that there are a lot of conditions. It also requires a lot of investment in terms of time.
ReplyDeleteI have been trying the permaculture approach for several years and based on my experience I do not see the productivity (in fact just getting a usable crop is a big issue). Too many things that I have planted have either died or just fail to produce a crop (insects, too much rain, too little rain, too cold, too hot, deer, rabbits). I have spent many hours hauling and spreading manure with relatively little to show for it. If I had to live on what I have produced, my efforts would only supply a small fraction of the food needed for a year. Hopefully, I can do better in the future, but I am now more realistic and expect much less.
I grew up on a farm and I know how much work is required. I still remember helping my grandfather pick and shuck corn using a horse drawn wagon to only harvest a very modest crop (several wagons load per day (about the size that would fit in a compact pickup). I also remember helping grandfather and grandmother make apple juice from apples that were quite wormy and even partly rotten. Everything just went into the hand press and out came the juice which was filtered through a dish cloth. It was all very organic but would not even come close to our standards today.
Today's factory farms are light years from even farming in the 40's and 50's. There is no comparison. We now have fresh vegetables and fruits available in the grocery stores year round. And the quality is picture perfect (perhaps not as healthy as the worm riddled produce I grew up with).
Just as an example of what is involved consider the row crop for vegetables. Today, many row crops, even in ideal climates, now make use of row covers. These are, in essence, single use unheated very thin plastic greenhouses covering just one very long row. The row covers not only help to moderate the temperature, but also provide protection from excessive rain, sun and from many insects. They also use plastic mulch to control weeds and insects. To top it off most of this is automated. Specialized machine install the mulch, seeds, row cover, and irrigation system in one pass. Other specialized machines will harvest one pass. They also require crops that mature at the same time.
I still don't like the factory farm, but its productivity cannot easily be matched. I now think that we are kidding ourselves if we think we can switch to permaculture based on a low energy world to feed even those of us who are willing to try.
Amazing job Karen. You must have been inspired by something. Very detailed and well done analysis and I generally veer away from predictions made by anyone. Just returned from a boat delivery from Alaska and I must say 3 wks not hearing any news and only rare minimal phone access to a society circling the post industrial drain was a pleasant interlude. I actually think the changes RESULTING FROM A SUDDEN DECLINE in energy availability and cost will not be predictable primarily because prediction in a complex adaptive system is fraught with too much uncertainty to be a useful endeavor. Cheap available fossil energy not only allows society to do all manner of work 24/7, it is the very basis of our wealth and fossil energy will not be easily replaced with renewable energy. There are many reasons for this from the obvious like the subsidies fossil energy provides to renewable energy to the less obvious such as the inherent thermodynamic inefficiency of converting fuel to electricity to distribution to the end user. Wind and solar wont cut it as a segue except in a very limited way. Wind is a superb energy source to do work directly such as Dutch windmills grinding grain or driving machinery but as a source for societies industrial energy in the quantities and round the clock reliability demanded of this industrial monster we live within........................not gonna happen except in a very limited way. Example: I lost my big boat alternator to a few blown diodes and was able to keep things like my electric fuel pump and navigation electronics and radar going because I have a big solar array on my pilothouse keeping the batteries charged but it did mean I had to anchor up pretty early and avoid high energy users like my autopilot and refrigeration. And when the sun didn't shine(common in Alaska) I turned off most of the electronics. BTW I own 3 tractors and the electric tractor pictured is a lawn toy. The front tires looked like they would fit on my corolla. I think the transition to reduced energy use is very likely to result from external shocks to the energy delivery system. It will take a few of these shocks to wake up the populace who of course will look for someone to blame besides themselves of course. I cannot foresee meaningful policy changes coming about to prepare and mitigate for the obvious consequences of a sudden withdrawal of energy and wealth. There are very few folks like you who are perceptive and intelligent and thoughtful of what is actually going on and what needs to be done. A few folks in a few lucky places will showcase demonstration projects of sustainability but the notion that intelligent planning by thoughtful intelligent people can smoothly adapt to the changes which will soon be forced upon us is I am afraid wishful thinking. As individuals we of course can make the changes in our own lives and environments to ameliorate the looming peaks and valleys ahead. The proof of my assertion is that aside from a few of us bloggers in a few somewhat aware and educated locales, ABSOLUTELY NO ONE ELSE in positions of authority are talking about this. Again thank you for your wonderful post. I did pick up many interesting tidbits and insights.
