Nouvelle-Aquitaine is a region in the southwest of France, with Bordeaux being its capital.

France, despite being a rather centralized, Paris-focused country relies on a decentralized approach for sustainable development, greenhouse gas (GHG) emissions reductions and energy saving. Thirteen so-called ‘regional energy agencies’ have been founded since 1995 engaging with regional actors and local communities. AREC (Agence Régionale d’Évaluation Environnement et Climat) is the environment and climate agency for the Nouvelle-Aquitaine region.

Many publications on energy and climate change are available on their website. Below is a Sankey diagram depicting the regional energy balance for Nouvelle-Aquitaine (Source: ‘Profil énergie et gaz à effet de serre en Nouvelle-Aquitaine – Année 2015 – Edition 2017’).

Flows are in GWh for 2015. Overall primary energy was 283.605 GWh, with 182.719 GWh final energy consumption. On the left side energy sources are split into imports (from outside Nouvelle-Aquitaine, 88%) and regionally produced energy, 12%). As is common in France, nuclear energy dominates the picture. On the right side we see the breakdown of energy consumption. The services sector (tertiary sector) is featured explicitly. It is responsible for 13% of Nouvelle-Aquitaine’s energy consumption, less than industry (19%) but more than agriculture (5%).

The Sankey diagram is very colorful and sports round icons. This goes well with the overall style of the report that targets explicitly at local communities and actors.

Styria is the second largest state of Austria, in the south eastern part of the country. It is famous for its beautiful mountains, its wines and some decent yodelling 🙂

It is also home to green tech industries, in fact “Styria is home to more than 150 clean technology companies … [whose] revenue totals €2.7 billion. This equals to 8 percent of the Gross Regional Product (GRP), and is one of the highest concentrations of leading clean technology companies in Europe.” (Wikipedia)

The ‘Styrian Promise’ is a project aiming at the implementation of energetically and economically meaningful energy efficiency concepts in Styian production companies. Case studies from food, textiles, metals and other industries are presented on the project wiki.

Above is a Sankey diagram depicting the energy balance at Obersteirische Molkerei Knittelfeld (Upper-Styrian dairy in Knittelfeld). Flows are in MWh per year. The main energy requirement is steam from natural gas: Whey drying and steam for milk pre-heating are the largest consumers of process heat. Read more detail on the dairy production here.

Published on the ‘The Efficient Appliances Blog’ is Pakistan’s First Energy Flow Diagram by Nida Rizwan Farid. The Sankey diagram is a piece of work fpr Pakistan’s Integrated Energy Plan and covers energy data for 2012/2013.

A more detailed explanation of the energy situation is given on this page. The author observes that “[o]ut of the 40.2 MTOE of final energy that trickles down the consumers, 72.7% of it is lost by the usage of inefficient appliances, motor vehicles and industrial processes. Only 10.96 MTOE of useful energy is received.”

The energy balance of the German city of Stuttgart has been mapped as a Sankey diagram.

This was part of the project ‘SEE Stuttgart’ (City with Energy Efficiency / “Stadt mit Energie-Effizienz”) and has been developed by Fraunhofer IBP research institute.

A vertical layout was chosen. Absolute energy flow quantities are not shown in this version of the diagram, but are available in the underlying study. In 2010 primary energy consumption in Stuttgart was 20.300 GWh.

The diagram is used to promote a better understanding of the consuming sectors in the city, and the types of energy used. The SEE project aims to reduce Stuttgart’s energy consumption by 20% in 10 years and to transition to non-fossil fuels.

Stuttgart has actually won a first prize in a competition for energy efficient cities in 2016. It is thus setting a benchmark for other German cities. The above Sankey diagram is featured in this promotional video (in German) [at 2:36] and also briefly in this video (in German) [at 0:48] by IBP Fraunhofer.
