Energy Flows in The Netherlands 2016

The below Sankey diagram depicting energy flows in the Netherlands in 2016 is very interesting. Actually it features two dimensions: energy production and consumption (from top to bottom) and energy imports and exports (from left to right). This is quite different from other national energy balances I have presented on this blog before (such as e.g. for Switzerland 2015, Chile 2015, Lithuania 2013, or Sweden 2014)

It can be found in the ‘Compendium voor de Leefomgeving’ (Environmental Data Compendium) a website run by the Dutch Government (Rijksoverheid) and is titled ‘Aanbod en verbruik van energiedragers in Nederland, 2016’ (Supply and consumption of energy carriers in The Netherlands, 2016).

Data for this Sankey diagram is from Centraal Bureau voor de Statistiek (CBS). Flows are in petajoule (PJ). Locally produced energy (‘Winning’) in 2015 was at 2.023 PJ, with a consumption (‘Verbruik’) of 3.155 PJ.
So, the Netherlands still had to import some 1.000 PJ to cover demand. However, it imported 11.275 PJ (‘Invoer’) and exported 9.559 PJ (‘Uitvoer’). In the first pace, the Netherlands seem to be an energy transit country. This is owed to the fact that Rotterdam is the largest oil port in Europe, and is a prime location for handling oil products (‘Aardolieproducten’).

Water Cycle in the Netherlands by G Singh

Just a quick post before the weekend: Visualization of the water cycle in the Netherlands by Gunjan Singh. See initial sketch and some comments here.

Quantities are in billion kg (=million tons). “The weight of the arrows depict the proportions most of the time”, exceptions are in the thin arrows at the right which would otherwise be fine hair lines only and almost invisible.

Amsterdam Energy System Visualized

Tom Van Heeswijk and Changsoon Choi, landscape architecture master students at Wageningen University in the Netherlands have created the below “preliminary Sankey diagram of the Amsterdam energy system”. This is part of the larger project URBAN PULSE described on the research page of the NRG lab website.

Only the top part of a larger Sankey diagram is seen here, the bottom part with fossil fuels apparently cropped. No units or figures shown, so just a schematic visualization.

Nevertheless some interesting features: in contrast to many other Sankey diagrams, nodes are not depicted with outlines but shown as gaps with their name. Electricity is highlighted as red bands while all other flows have a single-hatching fill pattern.

Beauty of simplicity…

Phosphorus Flows in the Netherlands

A recent visit to an organic farm and a chat with one of the staff on peak phosphorus made me search for Sankey diagrams on phophorus flows. Managed to find two, one of which is shown below. It is from an article ‘Phosphate recovery from animal manure the possibilities in the Netherlands’ by Van Ruiten Adviesbureau / Projectbureau BMA, for CEEP (November 1998) and shows phosphorus flows in the Netherlands in 1995 in million kg-P.

“It can be seen that 84 million kg P are imported in cattle feed alone (roughly 1/3 of the amount of P that is imported in phosphate ore). The excretion of phosphorus in animal manure is 86 million kg P according to the chart (about 197 million kg P2O5) … Moreover the figure shows that discharges of household and industrial waste water contain 10 million kg P. This is about 1/10 of the amount of P in animal manure.”

OK, this ia black/white retro style, but nevertheless a good Sankey diagram with flows to scale. Three vertical “columns” are for actual phosphorus imports: The largest quantity is direct imports (from phosphate rock, as phopshoric acid, and other organic phosphorous). The middle import column is for phosphorus embodied in food stuffs and animal feed. The third import pathway into the Netherlands is in waterways, such as the Rhine river, but this fraction remains unused. A large quantity of phosphorus is exported again (flows branching out to the left). 77 million kg-P per year accumulate in the soil. Another interesting detail is the flow labeled “stock mutations and statistical differences” branching out to the right.

Also see this post with a nitrogen flow Sankey diagrams from the Netherlands.

I will dig out the other phophorus Sankey and present it here in the near future…

Cool! Cyclifier 3D Sankey Diagram on Food

Found on cyclifier.org, a project run by Dutch 2012Architecten: This 3D Sankey diagram by Anna Brambilla visualizes flows of food from producers to the Rotterdam foodbank and onto low income households.

Source: http://www.cyclifier.org/project/foodbank (License: Share-Alike)

The image is explained as follows:

“Processes and actors are identified by labeled platforms with sub-processes shown as stacked platforms. The system boundary is shown as an extruded block indicating that it is one piece within a larger network. Starting from the edges of the cyclifier, distances are marked in intervals to indicate the distances traveled by inputs and outputs. Flows are scaled by mass as in sankey diagrams and are color-coded per flow type. Flows to and from the atmosphere are represented as traveling vertically.”

So, we have ‘Food and Organics’ flows (green), transport (yellow), users (purple) and even volunteer labor (brown) represented in the diagram. No numbers or units given though. Since cyclifier.org is interested in promoting “innovations that contribute to local exchange and production”, distances of producers to the foodbank and to the consumers are indicated on a somewhat logarithmic scale.

I just doubt that roughly a third of the output flows from food production is received by the foodbank. This is probaly to be taken symbolically and not for real…

Very cool Sankey diagram, kudos!

Water Flows – before and after

A reader of the blog, submitted the below Sankey diagrams on waterflows in the province of North Brabant in the Netherlands.

Wies writes about these:

The left chart is the actual Multi Input – Multi Output analysis. There are some irregularities and inefficiencies. Therefore we made the chart on the right showing some design proposals. These are not really related to exact quantitative in or output, it’s a bit more freeminded, so no numbers are included here.
We also tried to combine the actual flows of water with the bodies of water (troposphere in the air, the bulk of ground water in the ground)

The report that contains the two diagrams can be found here. Check out p. 22 of the PDF.

Thanks for sharing this!

Pimp my nitrogen Sankey

Below is an example of a Sankey diagram showing a nitrogen metabolism. The original diagram is from a Japanese publication (‘White Paper on Quality of the Environment in Japan 1994’), even though the diagram represents nitrogen loads (in 1000 tons N) in the Netherlands in 1990.

A pimped version of this diagram can be found in the e!Sankey download gallery. I don’t like the color very much, but the overall aspect of the diagram is much better than in the b/w version, I think.

They seemed to have struggled with inconsistencies in the original diagram, as an annotation suggests. Also the denitrification due to accumulation in the bottom sediment, or nitrogen ending up in durable goods (shown in black in the original) are not represented in the remake. For the rest it pretty much sticks to the original.

Thinking about a new tag “pimp my Sankey”…

Incoming and outgoing cargo @ Rotterdam Port

Last weekend I had the possibility to visit a friend in the Netherlands, and we took a tour of Rotterdam Port. Despite the bad weather, I was fascinated by the huge container ships, the cranes, the noises….

Back home I did some research and came up with the cargo data for the year 2005 from the Port of Rotterdam website.

I did the following three Sankey diagrams. The first shows the inbound cargo quantities (in million tons gross weight of cargo) from the left, and the outbound quantities to the right, broken down to world regions. One can clearly see that Rotterdam handles mainly imports, with more than 281 million tons of cargo being unloaded, while only 88,2 million tons of cargo are being loaded onto ships.

Next I flipped inbound and outbound flows to the same side. However, I think that by this the diagram loses somehow, also because some purple flows (outbound to Africa and Oceania) are too thin.

In the third version, I added a shape for the balance difference between inbound and outgoing goods.

Tell me what you think about theses Sankey diagrams. It would be interesting to compare Rotterdam to other ports. Shanghai, for example, might have the opposite picture with much more exports, but I haven’t found any data yet to show this. And, if we are talking cargo traffic: how about doing a passenger Sankey diagram for one of the international airports in the U.S. (by origin/destination continent?, by airline?)
