Open modeling/environmental NGO bridge



Release 03
02 February 2019


This thread floats the idea of a bridge between the open energy modeling community and energy and climate NGOs. The discussion here looks at Europe but the themes presented should be applicable anywhere.

To date, there has been next to no contact between these two camps. But I believe that should change to mutual advantage. The open energy modelers are now sufficiently advanced and organized to engage in substantial outreach. And the NGOs, as I will argue, should begin to involve, trust, and work more closely with their supporters.

The tools and practices for doing so no longer constitute barriers. Indeed, many of the methods on offer came from collaborative open source software (abbreviated here FOSS) development.

It is worthwhile stressing at the outset that public and open are different concepts. Code, data, and documents can all be made public without being open. The latter requires that suitable open licenses be added that permit downstream users to use, modify, and share the material. In short, the freedom to reuse.


To the best of my knowledge, established energy and climate NGOs have, for their policy analysis, relied solely upon:

  • closed source models
  • non‑open data
  • copyrighted reports

These NGOs often commission external consultants to undertake complex analysis, although simpler tasks are sometimes conducted in‑house using spreadsheets. These models are not made public and remain, in all practical terms, impenetrable.

Datasets, when published, which is a rarity, normally implicitly remain under full copyright and also European database protection (for instance Moore et al 2018). Reports are also not published under usable open access provisions either (refer to the Berlin Declaration 2003) (for instance Matthes et al 2018).

The one exception to the preceding comments is the Western Australian NGO Sustainable Energy Now (SEN) and their SIREN model (Rose 2016, Sustainable Energy Now 2017). It is also worth noting that the Union of Concerned Scientists (UCS) runs a fork of the US government NEMS model which is public domain only within the United States and hence not technically open source (refer to the 2007 Open Source Definition).

Modern environmental NGOs date back about four or five decades (McNeill 2001), while FOSS development began in earnest about three decades ago. These two phenomena have remained completely separate in their parallel worlds The environmental NGOs pushed political transparency and engagement but most did little to involve or trust their memberships.

In contrast, the FOSS projects stressed openness at every turn — legal, technical, and social — and built an ethos of contribution, merit, and consensus and more recently inclusion, civil conduct and conflict resolution. A central theme throughout this evolution was the lack of a need to seek permission and hence also the freedom to fork a project and head elsewhere.

Similar conventions were later developed for authoring online encyclopedias and collecting citizen‑generated data (Lämmerhirt et al 2018). Wikipedia, for example, encourages participation by stressing “be bold”.


In late‑November 2018, I began contacting NGOs in Europe — off my own bat using the no need to seek permission doctrine just described — to float the idea of a bridge meeting in Berlin in early to mid‑2019 to discuss opportunities for collaboration.

I won’t list the individual organizations here but I can say that several attempts were required to make useful contact with the incumbent NGOs.

A newly formed environmental group however, Extinction Rebellion (XR), launched on 31 October 2018 in the United Kingdom (Green and Scott Cato 2018) and which, four weeks later, had established nascent branches throughout Germany, France, and elsewhere, was much more receptive. I duly made contact via their generic email address in early‑December and received an enthusiastic response (the only one in fact). XR are diametrically opposite to an incumbent environmental NGO in almost every regard and indeed exhibit many characteristics of a FOSS project. So it is no surprise to me that XR saw opportunities where established environmental NGOs could not.

A Danish research project had also earlier created a website to encourage third parties to submit future energy system scenarios. But, despite prompting, no environmental NGOs engaged.

Satellite communities

There are various ways that established NGOs could interact with the open energy modeling community. These might include:

  • directly commissioned research (I am completely unaligned here)

  • associate with or even endorse modeling projects and prompt analytical directions (rather than specifying scenarios in detail)

  • develop online satellite communities for formulating scenarios and undertaking analysis and interpretation

I personally favor the third option — online satellite communities — having seen what FOSS development can accomplish. These satellite communities would not design the models, write the core code, or collect and curate primary data — the open energy modeling community is instead actively engaged in those tasks. Rather the satellite communities would formulate IPCC‑style storylines, select modeling projects, develop scenarios, populate the models with data, run the models, and then collate and analyze the results. A tight integration between the model developers, the data portals, the satellite communities, and the host NGOs would no doubt result.

These satellite communities are tentatively forming in other modeling domains. For instance, Extinction Rebellion, barely ten weeks old, has begun discussing building its own sustainability modeling capacity (XR‑DE community). Other domains, such as agriculture and economics, could also follow a similar route (although I am not aware of any activity aside from data assembly).

It is worth noting that the OSeMOSYS project is undertaking something similar, but with a focus on government agencies in developing countries (that’s the only project I am going to mention here). Their processes are also more formal than I envisage initially and their efforts are supported by multilateral institutions.

Stepping back, I believe it time for the incumbent NGOs to learn from and embrace FOSS development methods for their core policy analysis. The current practice of commissioning closed model analysis is a poor fit with their calls for public transparency and engagement. Moreover, it is hard to imagine that single institution closed source energy models will exist for much longer — having been out competed by their open source compatriots.

Possible ways forward

After discussions with the organizers of the Aarhus workshop (22–24 May 2019 forthcoming), we agreed to hold a plenary session to discuss opportunities should NGO representatives wish to attend.

Otherwise the idea of a one‑day bridge meeting in Berlin remains on the table. People can contact me directly if they wish although I am keen to broaden out the organization.

And the dialog can continue below of course. If you provide corrections or observations, I’ll update this posting too. R.

North America openmod workshop series
Do-a-thon on COST grant for openmod activities

I really like your push forward in this direction, thank you Robbie!

There was the Bits & Bäume Conference in Berlin last November 2018,
which was aiming to crossover sustainability and digitalisation.
I believe some openmodders where present; maybe there were more ideas exchanged which could be added?

I also think that is the approach to aim for. Not only would this increase transparency, but allowing for involvement (thinking in the direction of Citizen Science here) could

  1. increase the acceptance and understanding in the public of scenarios and results
  2. increase the relevance of research questions and scenarios from the point of view of also single ‘critical’ individuals

As Tom brought up the openmod’s 5th birthday and a extra special event in Autumn 2019 and in conjunction outreach of the openmod community to other continents: NGOs could be valuable if we want to increase our outreach/branching to especially African/South Asian/South American countries. There could be some strong synergies if we couple the NGO outreach with the special event and the nearly carbon-neutral (NCN) conference idea.



thanks Robbie for this really interesting thread.

I also agree that having an interaction with NGOs would be important for all the reasons you explained, and probably shaping the interaction in the form of satellite communities as the ones you described (i.e. ones that may help building an “extended peer community” [Ravetz, 1999] of people involved in the definition and enrichment of scenarios) could be the best option.

Even more than an opportunity, I think that a continuous and solid discussion with these NGOs is something that the openmod would need to timely and carefully manage, to ensure that the thing keeps going in the direction of increasing the quality of our analyses for the benefit of the whole community of people fighting for decarbonisation, and not the opposite. In fact, it’s worth underlining that (if not timely discussed) the thing might go also in another direction, as it may seem, for instance, for the experiment you mentioned of XR-DE (which, by the way, I am myself following with interest) of using IAMs for doing their own analyses: in short, I feel that, if every random NGOs starts running scenarios without taking care of building an extended peer community with the modellers themselves, there’s a good probability that at some point there will be a bunch of low-quality scenarios out in the web, which might be taken as a pretext to discredit the quality of open models altogether.

So, I do think that it’s really a great thing if NGOs (especially new ones, as XR) start getting interested and involved in open-source modelling, and I do think this could benefit a lot to both of us, yet only if the relationship between the modellers and the NGOs is timely and properly established on the basis of continuous discussion and reciprocal involvement, just as you suggest. So, let’s keep this discussion going.

One comment and a short update. I am sticking with my policy of not naming names (beyond Extinction Rebellion) for now.

Regarding poorly thought through scenarios. Running the scenarios adds a certain rigor to the process. For instance, local and regional energy autarky has quite a following in green circles in Germany and doubtless elsewhere. As most here will know, renewable energy has to be shifted in time (storage) or space (transmission) to cover some given demand trajectory for energy services (exhibiting various degrees of flexibility and importance). So those favoring flat or reduced transmission capacity will, speculatively, find such systems exhibit low aggregate efficiency (round trip storage being more lossy than transmission) and/or high curtailment (harvesting technologies being cheaper than storage technologies), both with significant implications for affordability and ecological cost. It matters not whether my example is correct — the point is that the process of modeling embeds its own exigencies. And if some mavericks manage to locate unorthodox high performing solutions, well that’s great! Weise et al (2014) expands on this view of open modeling as a necessary condition for public participation.

The NGO reactions thus far have been interesting. I would say most have little to no idea as to:

  • the potential of open development and how the associated communities might function (beyond Wikipedia)

  • the potential contribution of (open or closed) energy modeling to decarbonized futures (beyond Microsoft Excel)

One established NGO commented that they like their reports to create a “splash”, meaning they can promote their conclusions on mainstream and social media and gain publicity. I’m not sure if open development excludes that activity, but it is something to bear in mind. And this activity is certainly not limited to NGOs — scientific bodies also have media teams who would probably strongly resist a move to “continuous integration”. I think I’ll file this issue under “institutional ego”: something that does not sit well with FOSS development.

One NGO asked about including land use in our assessments. One approach is the nexus concept, which some projects are now working toward (Brouwer et al 2018).

@tom_brown pointed out offline that analysis using SWITCH was used to simultaneously support and advocate for a law on 100% renewable generation by 2045 for Hawaii. Fripp (2016) provides background.

The openmod “associated” (the openmod cannot apply in its own right) COST application (discussed here) will probably include a component for NGO outreach. So we need to think about how that might be best operationalized.

Finally, those who like to loiter on twitter can follow #freethemodels By all accounts, similar sentiments to those here but quite a different audience.

Another update following several more conversations. A well‑known NGO is apparently considering a strategic shift away from analysis and toward action. My response is that the satellite community concept (outlined earlier) can and should span both aspects.

Inconvenienced car drivers at an anti‑coal protest in Berlin on 1 February 2019 questioned protesters blocking their way as to whether 100% renewable generation was indeed possible. A good question. Some incumbent NGOs blithely say yes — but with no real understanding of the system architectural, market design, public acceptance, and related challenges and trade‑offs that lie ahead.

Numerical studies from the open energy modeling community (and others) indicate too that the answer is yes (for instance, Brown et al 2018). But more importantly, these studies can articulate and shed light on a number of key questions that the interested public will need to address regarding which 100% renewable future they would prefer or at least be willing to accept.

Experience in Hawaii with the SWITCH open electricity system model and a fork developed by E3 shows that NGO involvement and advocacy can work in tandem with sophisticated modeling and analysis. These two tweets from communications lead Kamal Kapadia indicate the role played by the Blue Planet Foundation:

Just some context and a plug for my organization, #BluePlanetFound: Hawaii was first state in the US to pass a law requiring 100% RE by 2045. The critical factor was advocacy and collaboration between non‑profits, who used research and models strategically.

#BluePlanetFound literally pounded halls of State Capitol every year for 10 yrs to get this law passed. Early on the Governor called our Exec Director “Harry Potter” for pushing for 100%. But now it’s the law. So research/models PLUS advocacy is key.

Therefore, European NGOs should not deprioritize analysis to capitalize on rapidly ramping public concern about our climate emergency. They should also recognize the need for the interested public to work on solutions too (Wallace-Wells 2019). It would indeed be retrograde to see NGOs and their umbrella organizations swap to sloganeering and mobilization without also contributing to a longer view. Emphasizing urgency is useful, but we also need a common and open journey toward deep and necessarily highly intertwined solutions.

On a more practical note, one German NGO and one Berlin university research group have tentatively offered to host a meeting in Berlin. More soon.

The following diagram shows the kind of relationships that might develop between a satellite community, the open energy modeling community, an energy and climate NGO, and the interested public. My thanks to Michael R for prompting the original sketch.

Details of the actual bridge meeting are currently being worked through and I’ll post back after the details firm up a bit more.


This looks very interesting - thank you for posting :-)! One question that we should probably check at some point would be how the activities of the Satellite Group would be funded? In case of a successful COST grant to support OpenMod activities , we could probably fund networking expenses, but would still depend on modelers / NGOs etc willingness to dedicate their time…(pro-bono, or as part of other projects etc.) so it might be good to collect expressions of interest for that at some point (which may be after the meeting, once we fleshed out more details regarding the activities of the “satellite group”).


Funding. Always a good topic! I guess I saw this activity being funded the same way the Linux kernel is. Essentially contributors gain benefits they could not achieve working alone or through other avenues. For Linux, first came Linus, then some hobbyists, and later the corporates. Kernel contributors now number 16 000 including skilled developers. No money is transacted, at least not directly. Or is Linux a bad analogy? Am I being too cavalier?

From another angle, I see quite a number of maturing openmod‑related workflows converging here. Technical data standards and information semantics. The models themselves, either intact or split into components for reuse (or scavenge if you prefer). Data portals being stocked and curated. Model classification, model comparisons, and model quality reviews just beginning but should prove invaluable. Many of the building blocks are present already. What we lack — with the model‑specific exceptions of Balmorel and OSeMOSYS — are user communities.

An IT‑savvy community liaison manager could help get things rolling. Set up some online communications infrastructure, preferably self‑hosted. Arrange video and physical kick‑off meetings. Engage in outreach. (Would anyone like to explore funding for this kind of support?)

The biggest challenge is not financial or even infrastructural — it’s helping the energy and climate NGOs understand this unfamiliar world and the potential benefits on offer. Most everything about open source is strange to them. It is geeky — and not many NGO staff are analytical let alone numerical. The self‑organized chaos. The legal issues and the centrality of open licensing. How best to interface. Will their brands somehow be at risk. And ultimately, a level of disbelief that self‑selected online communities can manage and advance complex projects that they themselves struggle to tame. On that note, the Linux kernel is currently costed at around USD $10 billion.

There is also a need to demonstrate to the NGOs what open energy models can do. That will be a key part of this bridging exercise. But the openmod community also needs to listen to the NGOs to better understand their objectives, challenges, agendas, and constraints.

I want to finish with the comment that not everything can be open. Protected industrial know‑how and information which can identify living persons are both off limits. But in between those two bookends, there is a lot of space to work within.


Plenary session at Aarhus workshop

@felix.reitz, energy analyst, Europe Beyond Coal, and myself @robbie.morrison have a 30‑minute plenary session on this topic at the next Open Energy Modelling Initiative workshop in Aarhus, Denmark, scheduled for 10:00–10:30 on Friday 24 May 2019. We plan to record the session and make the video available under a Creative Commons CC‑BY‑4.0 license.


I am in two minds as to how much separation there should be between satellite communities and individual NGOs. Both close and distant could work. A close community should see a tighter binding between the analysis and the campaign objectives of the aligned NGO. And more direct support. While a looser arrangement would give the satellite communities more autonomy. Moreover, umbrella organizations, such as Europe Beyond Coal or Climate‑Alliance Germany, could act as intermediaries, interfacing between the community analysis and the research needs of their partnering NGOs.


One‑page elevator pitch

This elevator pitch proposes a bridge between the open energy modeling community and energy and climate NGOs within Europe. To date, there has been little or no contact between these two camps.


Energy models are used to explore future energy systems, usually to 2050, by analyzing scenarios.

The Open Energy Modelling Initiative (openmod) is a grassroots network of energy system modelers pursuing open analysis: open source models, open (as opposed to simply public) data, open access publications, and open science. We number about 500 and are now sufficiently advanced and organized to support serious public policy analysis. See wikipedia, our forum, and our mailing list.

While many environmental NGOs argue for public process and transparency, their policy formation is often opaque and non‑reproducible, due to closed source models, withheld data, and copyrighted reports. Not only is this ethically inconsistent, it also means that substantial resources remain untapped and that a proven (open source) development model lies dormant and wasted (Morrison 2018).

The European Commission is shifting to open energy policy development and open science. The incumbent NGOs risk falling behind accepted scientific standards if they don’t follow suit.

Proposed Berlin meeting in mid-2019

A one‑day physical meeting is being planned for mid‑2019 in Berlin, Germany. It will most likely be hosted by the CoalExit group at TU Berlin and organized by CoalExit (Pao‑Yu Oei), Germanwatch (Eva Schmid), and myself (no institutional affiliation). The meeting will provide an opportunity for:

  • open energy system modelers to showcase their capabilities
  • NGOs to share their experiences of working with energy models and data
  • a discussion on how best to work together going forward

Satellite community option

The following diagram indicates one possible game plan. A satellite community would be independent and would draw strongly on open source development methods and tools. Careful separation would limit the reputational risk for any associated NGOs.

release 05 of the satellite diagram

Open energy system modelers expect substantial benefits with a move to open analysis. Model‑mediated public consultation is arguably unavoidable, given the system and policy complexities involved. And NGOs could transition to a supporter engagement model fit for the early 21st century. ▢

Hi Robbie, thanks for pushing this topic and connecting the people. I can offer to present the OEP and our community based open science concepts.


Bridge meeting • Monday 17 June 2019 • Berlin, Germany

Caution: this posting is dynamic, you can view its history via the orange pencil icon just above.

The bridge concept seeks to improve the transparency and quality of analysis used by energy and climate NGOs, the legitimacy of future energy system scenarios used by energy system modelers, and the contribution from civil society to preparing for a rapid and just transition to zero‑carbon energy systems.

A date has been set for the first one‑day “bridge” meeting in Berlin:

  • Date: Monday 17 June 2019
  • Duration: 11:00 to 17:00 followed by an optional restaurant meal nearby
  • Venue: Technische Universität Berlin (TU Berlin), Berlin, Germany
  • Host department: CoalExit group, Workgroup for Infrastructure Policy
  • Approximate location: OpenStreetMap (for planning transport and accommodation)
  • Transport hubs: Berlin Hauptbahnhof, Tegel airport (TXL)
  • Travel tips: TU Berlin
  • Cost: no cost but meals not included
  • Language: english preferred
  • Selection: NGO representatives will have priority and diversity considerations will apply in the event that participation needs limiting

Online registration will open toward the end of April.

Energy and climate NGOs are encouraged to contact the organizers and register interest. In particular, NGO campaign staff and supporter engagement staff should volunteer themselves to give presentations. It is important that this bridge has foundations at both ends!


The next openmod workshop at Aarhus, Denmark has a 30‑minute plenary session scheduled on the bridge concept. The session will be videoed and later made available online.

A number of official agencies are interested in this type of open analysis and public engagement and some are considering sending representatives.

Sources of funding for a community liaison manager and sysop support are being explored.

Tentative program

The first part of the program consists of open energy system modelers describing their research and work practices:

Presenter Theme
Pao‑Yu Oei Welcome
Eva Schmid Introduction
Robbie Morrison Open analysis using online communities
Tom Brown What are open energy models and what can they contribute
OPSD representative Open electricity sector data and community curation
Ludwig Hülk Backend technical support and community‑based open science concepts

The second part of the program will be energy and climate NGOs sharing their experiences and expectations regarding energy analysis and position formation. That part of the program is currently under development, in part awaiting interest from the NGOs themselves.

Presenter NGO Theme
Eva Schmid Germanwatch tbc

The third part will be a discussion among participants on opportunities going forward.

Optionally, participants can decamp to a nearby restaurant to continue the exchange.


The one‑page elevator pitch has been updated. Please download this version and circulate it as you see fit.
