Build out: The Grid vs. The Household - Towards a Community-based Solution to CC and PO

Originally published on theoildrum.com here in response to this on this thread which all started here. The post has been modified for this space.

The Grid vs. The Household

Some believe we have time before a crash, or, that there will be no crash, but a relatively smooth transition from fossil fuels to renewables. They believe this slow decline in fossil fuels will allow the time needed to build hundreds (the U.S.) and thousands (the world) of nuclear power plants/reactors. However, the assumption there is time and/or there will be no crash is a dangerous one. Failure to prepare to mitigate the effects of a swift decline in energy will almost certainly lead to disaster. We must look at risk.

When we can provide a huge amount of power for a fraction of the cost and time needed to build up our nuclear grid to a level that will protect us from oil production decline, why would we not do it? Nuclear plants take years to build and require very skilled workers that must be trained. In Return to Olduvai they estimate a minimum of 20, and an upper end of 90, new reactors and/or power plants per year. At 5 - 12 billion each. That's up to 12 TRILLION dollars for the U.S. alone. But where is it written the backbone of our power grid must be built before the localized, household-based renewable infrastructure? Why shouldn't they be built concurrently, at least?

My proposal is intentionally localized due to the high degree of certainty (my certainty, not a consensus) that neither the government nor the market will be able to handle this in isolation. You have the perfect example in WWII. Victory gardens weren't just a good idea, they were necessary for continued good nutrition. The same went for resources, which led to rationing and recycling.

My position on global warming is the same. The best thing we can do is build nuclear reactors to displace coal power plants.

How can the best we can do be something that is unsustainable? Nuclear plants will need replacing two or three times a century at a current cost of billions per. The localized grid will, too, but, again, you are looking at a very small fraction of the cost for the same degree of replacement. For the same billions per *one* reactor we can supply a good fraction of the total power generation needed and leave the robust solutions for backbone, greatly reducing the number of large plants we need. If we add to this equation lifestyle changes of reducing, recycling, reusing and localization, all the more so.

I would argue, in fact, that meeting the localization goal is more important because it deals with the real issue: consumption. A massive localization drive could achieve partial energy autonomy for every household in the US within a period of a few years, not decades. It would have the added benefit of *requiring* lifestyle changes with concomitant savings of energy by reducing use via the renewables and behavior changes. However, if we assume we have a 5 - 10 year period before the shit really hits the fan, then the current grid supplies the backbone as the new backbone is built out. Under this scenario, deprivation may be eliminated for some or all over that initial time span.

Additional benefits occur from the localization of the household-based energy build out. In order to achieve this, there will be flexibility needed. Economies of scale interfere if we just assign a few companies to build all the windmills, heat pumps, solar panels, retrofitting materials for homes/apartments/businesses, etc, needed. No, the key to the plan is that it be localized solutions built out by local people wherever possible. This means, for example, the scavenging of materials needed everywhere and anywhere possible, rather than the manufacture of new materials. In the cities, we would likely need to commercialize the process a bit, but hopefully only to the level of resources. I imagine a return to the days of barn raising, but with windmills, etc.

By making this a community-based process where community solutions are customized by the community with assistance from knowledgeable locals or other reference persons/professionals, we instantly integrate the whole system into a localized whole. This might have the added benefit or reducing the need for relocation. A localized solution of this magnitude would save incredible amounts of financial resources. Those resources might be applied to some of the macro level solutions (things other than backbone) that certain communities, such as cities in the southwest dealing with water shortages, might need.

If real net oil production declines of 4% or more a year set in, we will never have the opportunity for [a nuclear and/or BAU grid-type] plan. My plan would have a good chance of succeeding whether those declines come or not. This is simple risk analysis.

I realize a great deal of interest and even fun comes out of the intellectualizing entailed in the intellectual process we are all engaged in at TOD to deal with Peak Oil and Climate Change, but the time for chat and brainy ideas is quickly passing, if it has not already passed us. I hope to encourage people to begin narrowing the conversation to the realities at hand and try to get to some conclusions before the decisions are taken out of our hands by circumstances.

Tom Whipple serves up a similar view of the future. His article doesn't deal with the sequence of events, but does outline a vision of where we may end up, albeit not in a collapse scenario, per se.

The Peak Oil Crisis: Catenaries and Pantographs

As the availability of liquid fuels dwindles, those supplies that remain will be increasingly allocated to uses for which there are no readily available substitutes -- such as powering aircraft and ships. Electric power for land vehicles appears to be the most realistic option for the present...

...For the immediate future only electricity, which can come from conservation of existing power production, nuclear power stations and renewable sources, appears to be the most likely power source for land vehicles.

Powering cars and light trucks with electricity does not seem to be an insurmountable problem provided that one is willing to live with their limitations...

The U.S. currently has some 230 million light vehicles in its fleet... these vehicles are simply going to be abandoned...

...At the rate our natural resources are running out, however, it is doubtful we will be building and selling 100’s of millions of non-fossil fuel cars in the foreseeable future.

...new rail lines would... use diesel-electric power initially... electric-powered railways coupled with short haul electric trucks, busses and cars...

...One idea... was to repower our long-haul trucks with electric engines, some battery capacity, and pantographs to contact overhead wires...

...We already have some 2 million 18-wheelers in America and one would hate to see them scrapped for lack of fuel.

...When affordable liquid fuels dry up, we are going to be left with a lot of vehicles and their infrastructure that will no longer be of use. With a little imagination, time, and money, much of this stranded investment can become useful again. There certainly will be powerful incentives to introduce whatever works.

The abandoned vehicles and infrastructure could instead be intentionally converted, before abandonment in at least some cases, to be used in the build out I outline above.

I agree with Tom:
In its day, the internal combustion engine was a wonderful device that served us well for over a century. That day, however, will soon be over. It is time to start thinking about and planning for alternatives.

Lucy! We're hooooome!

The image is at once unnerving, surreal and calming: coming home to a place you no longer know, and that no longer recognizes you. Walking the dusty ground and the ancient rock of Olduvai must be an awe-inspiring experience for those from a more modern world. The sort of experience a typical American might get visiting some of the very old or ancient sites of Europe, our sense of the age of human kind being so poorly developed by TV, video games, shopping malls and the like. Having seen Roman columns in Sevilla Spain, ancient forests in Costa Rica, stone temples in Korea, and more, I can imagine just a little the awe that might come over one at Olduvai speaking a silent "I'm home" to Lucy.

Going home again tends to be either joyful or traumatizing - or at least stressful. How and why we go home matters. Home for the holidays to a warm and loving family, who wouldn't look forward to that? Home for an extended period after the collapse of a marriage, hitting hard financial times, to care for a sick and/or dying parent... who would look forward to that? The one is full of happy moments (perhaps punctuated with the old bickering that families all do), the other is full of self-doubt, uncomfortable explanations, broken expectations and the sheer difficulty of living differently in a place that is no longer yours. These may be the choices we face as we race towards the end of cheap energy (at least, unless or until we harness solar energy on a grand scale).

In Olduvai Revisited 2008, an update to the Olduvai Gorge Theory proposed by Richard Duncan, Luís de Sousa and Euan Mearns of TheOilDrum:Europe present to us the choices we may face in how we go back to Olduvai Gorge. In a series of scenarios for the end of the Fossil Fuel age, the data suggests we may yet have a choice as to how we go home. We can go home beggers, paupers, broken and beaten, or we can go home with good news of grand new ways of doing things, and maybe a better life for all. They conclude:

According to our analysis, conventional fossil fuels are set to peak in a decade or so and following that, decline will open an ever widening gap from today's per capita energy use. Based on finite FF resources, energy per capita is indeed headed towards a cliff, and this may lead Mankind back to the Olduvai Gorge if action is not taken to address this problem. Many of those who have studied this problem in the past have concluded that the journey back to Olduvai is unavoidable.

The analysis presented here suggests that it is within the capacity of human endeavor to build new energy gathering infrastructure to substitute for the decline in conventional fossil fuels. By combining energy efficiency measures with the simultaneous expansion of solar, wind and nuclear energy Mankind may secure a civilised existence for the XXI century. A tremendous opportunity exists to build a more sustainable energy future and building this future will provide vast opportunity for economic growth and prosperity...

The next two to three decades are crucial, where the fastest build of alternative infrastructure is needed, and when the efficiency wedge will have the slowest effect. But the numbers contemplated here are not insurmountable, and should be tackled with the right commitment and timely action.

We have a choice. Do we go home to Lucy for a visit to our ancient ancestral home full of hope, vigor and new ideas for the Old Mother to squint at and whisper small wonders at, or do we go home out of desperation to share what little resources remain, struggling to survive as long as we can before the dust covers our bones and we are dug from the rock in some far future? Are we to be wondered at by beings puzzling at how we could have traveled so far just to end up back where, and how, we began?
