Greening the energy sector: Examples from the beautiful small town of Pirna

On June 08, the participants of our 45th UNEP/UNESCO/BMUV International Postgraduate Course on Environmental Management for Developing Countries (EM45) visited Pirna and had the chance to meet two of Pirna’s representatives to exchange on climate action within the field of renewable energy. Participants Mustika Aji Hertanto from Indonesia and Jolly Kayiita from Uganda submitted an insightful report about what they took away from the meeting:

“On Wednesday, 08 June 2022 at 9.15 am, the participants of CIPSEM’s EM45 course arrived in Pirna, a town located 17 km away from Dresden, a place that would further surprise us on how they are involved in climate protection through their management in the energy sector. Before arriving in Pirna, we never thought that a beautiful small town with 40,000 inhabitants and 53 km2 area would teach us a lot with their achievement despite their minimum resources. It reminded us of an old saying that said “revolutionaries come from minimum resources”. Yes, Pirna is the real example of that, they restore our faith in the positivity, something that is very expensive lately, since we are too busy to deal with politics and interests.

We were warmly welcomed by Markus Dreßler, the deputy mayor of Pirna, and Thomas Freitag, Pirna’s climate protection manager at 10 am in front of the town hall. They kindly told us about a brief history of Pirna before inviting us to the meeting room inside the town hall. The friendly atmosphere at the time was blurring us that those two people in front of us were two of influential persons in Pirna, the persons who bring change to that beautiful small town.

Mr. Dreßler, in his welcoming speech explained that Pirna has been involved in the climate protection and focus on the energy. Recently, they also joined the European Energy Award (EEA) because it allows the structure of the municipality to deal with climate protection and its external guidance. They worked very hard to make sure that the city can contribute to the betterment of the world through renewable energy. This line was punching right on our face. How could a small town that was slowly left by its people to other cities for a better life, work really hard? They devote themselves as much as they can regardless the minimal resources they have and political interest they found in the process. The way they work is to avoid distraction and not to spend too much energy in analysis but in the implementation to achieve the target. As a result, Pirna is in a good way to receive a gold category in European Energy award (EEA). They have many milestones since 2008 and recently in 2021, they received a certification with EEA gold. They focus on their renewable energy in the heating system and to light the city.

Another learning we get from Pirna is on how they mix the top-down and bottom-up approach by considering the balance of the environmental impact and the financial balance. This is very important because as environmentalists we sometimes are too research-based and do not consider other interest. This is surprising because to their knowledge, this approach is effective to convince people that still do not believe in the climate change. Again, we learn how a small resource can be a revolutionary if they have an inspiring leader. Lastly in Mr. Dreßler’s closing remark, there is still a target that is difficult to achieve. It is to implement more PV in new building and the establishment of wind energy. The economic reason and many conflicts of interest become the reasons why such a good initiative is hard to implement.

In brief, we also learned a lot about the development of climate protection work in Pirna. In overall score, they have 79.4% assessed based on 6 actions of EEA:

  1. Development and spatial planning energy
  2. Municipal buildings and facilities
  3. Supply and disposal energy, water, waste water and waste
  4. Communication and cooperation
  5. Internal organization energy team
  6. Mobility public transport

In the process, they apply a municipal energy management which is a systematic and continuous development of non-investment and low-investment savings potential in the operation of municipal buildings. There are three main reasons why Pirna applies municipal energy management:

  1. Reduction of energy consumption
  2. The increasing costs for energy
  3. The increasing demand for energy

To not burdening the people, the municipal has a smart initiative by implementing leasing model in the photovoltaic system. They also have many environmental programs such as E-carsharing for the municipality fleet, city gardens Breite Straße, energy projects in school, exchange of experience with twin towns and many more.

Before finishing the excursion, we were invited to go to Carl Friedrich Gauß Schule, an exemplary of the passive house, a place that has a very low energy consumption. Built in 2013, the school implements 4 heating systems:

  1. Heating pump below the ground
  2. Heat and power plant combination
  3. Air exchange
  4. Heat capture system

The school has a very good control of air control, the running cos is even cheaper. Yes, there is a challenge in the investment cost, but compared to long term financial benefit, it is economically efficient. Another challenge is that there should be a zero error in the building planning. It needs collaboration between the architect and energy consultant.

In the return to CIPSEM, we were wondering that we were very lucky to have a chance to visit one remarkable town in the saxony. Somehow, we also reflect to ourselves that we may complain a lot about resources that hamper us in achieving the goals, even we sometimes use it as our justification why our target is not achieved. Pirna realizes us that we should not complain with the resources we have; Pirna reminds us that hard work combined with smart initiative are the key of a successful action; and lastly, Pirna inspires us that no matter how hard the challenge, everything is possible.”

A little bit about the Research Centers in Germany…

Energy from biomass?

Yes, it is possible!

On the morning Monday of May 20th, EM42 fellows headed to the central station of Dresden, bound for the beautiful city of Leipzig. After a short trip and a small break, at 1 pm they arrived at the “German Centre for Biomass Research (DBFZ)”.

During the visit to DBFZ, they learned about the different processes to produce energy from biomass; and after a short explanation about the organization with international colleagues from China, Spain, Canada, Brazil, and Italy and the vision of sustainable resource basis, smart bioenergy – innovations for a sustainable future, they proceeded to visit its installations and laboratories that are divided into five departments: biogas, refinery, hydrothermal carbonization, heating technologies, and wood combustion.

Additionally, they had the opportunity to meet some of the researchers of the institution, as they explained to them; DBFZ with approximately 250 employees researches how to generate energy from biomass resources. In this regard, DBFZ works in joint collaboration with public and private institutions around the world.

Something that 30 years ago seemed impossible, now is a reality thanks to institutions like DBFZ that bet on studies based on the applied researches that develop practical solutions to current problems related to the integrated bioenergy provision.

The second day in Leipzig at 09:30am, EM42 fellows arrived at the “Helmholtz Centre for Environmental Research (UFZ)”, they were welcomed by Mr. Andreas Staak who introduced the visitors the UFZ installations, along the day some researchers explained in more detail the projects that UFZ is developing; as is the case of the “Center for Advanced Water Research (CAWR)” presented by Prof. Olaf Kolditz and Mr. Lars Bilke from the Visualization Laboratory; whom explained some projects developed for Asia (China and Jordan) related to water sustainability, at that time, the 3D animation developed by UFZ for the spatial planning was one of the most incredible experience that the fellows tried that day.

After the lunch at UFZ canteen, Prof. Martin Volk presented the topic “Assessing and governing synergies between food production, biodiversity, and ecosystem services”; Additionally the Department of Urban and Environmental Sociology and the Department of Ecological Modelling presented some of the projects that UFZ is developing related to food-waste-energy sustainable environment; and impacts of the new policy instruments, technologies and change processes on pastoral land use as a social-ecological modeling approach.

Finally, the fellows had the opportunity to enjoy the game “NomaSed” developed by the Department of Ecological Modelling in order to create awareness to the stakeholders about the land use in agriculture activities. Of course, there were winners in this game!

Berlin – between the future and the past

The CIPSEM trip to Berlin from the 20th to the 22nd October was a truly marvelous experience. The excursion to the German Energy Agency and the German Energy Association of Energy Cooperatives was overly interesting and useful. Both resource persons had an excellent sense of humor which greatly contributed to a sense of camaraderie among the group.

However, for me, the true highlight of the excursion was being able to finally practically envisage the remains of the Berlin Wall after having been provided with an excellent historical overview in our first week at CIPSEM (complete with a quirky, hilarious video!!). Looking at the wall was a truly humbling experience as I was mentally transported back in time to the 9th of November 1989. I imagined the scores of people who had come to witness this historical occasion, the breaking down of a barrier that had separated brothers, sisters,sons, daughters cousins, friends…..finally being brought down. The tears of joy commingled with tears of anguish brought on by the effusion of emotion on this day must have flowed both fervently and freely. I stood there transfixed next to Checkpoint Charlie and imagined individuals getting their passports stamped in order to cross into West Berlin and back into East Berlin.

The enormity of it all cannot be put into words. Staying on an extra day after part of the group left Berlin allowed myself and one of my colleagues to take a city tour on the ubiquitous red “double decker” bus. We were taken on a trip down memory lane to Karl Max Street, complete with the German Democratic Republic (GDR) styled houses whose design was mandated by the government at the time, complete with certain symbols above the eaves of each window. We also got to see the captivating Berlin Bridge in seemingly suspended animation with the modern day yellow train traversing its lower reaches, a perfect juxtaposition of the ancient and the modern.
My Berlin experience was a personal indictment of the fact that a Wall could not and cannot solve political or ideological differences in the past or in the present.The willingness to respect other people’s opinions and genuinely listen to their viewpoints is what ultimately will see a semblance of peace returning to our tumultuous world.

Berlin Adventure

By Gulnara Anapiiaeva (Kyrgyzstan)

It’s mostly known that capital city of each country has more options on each sector, as it concentrates governmental and non-governmental institutions. CIPSEM organized a study trip to Berlin between October 20 and 21, 2016 and we, the participants of SC69, could have this opportunity to visit several federal and non-governmental organizations. In addition to this, we could explore Berlin’s historical and cultural sites between courses.
Our first meeting was with Mrs. Königsberg, who took us to discover the nearby surroundings of the BMUB (Federal Ministry for Environment, Nature Conservation, Building and Nuclear Safety), since it is located in an area having historical traces of the border zones of Eastern and Western Berlin. Mrs. Königsberg was very enthusiastic to speak about the situation in Berlin during the 1962-1989 years. Participants were eager to listen and asked questions even though it was cold and cloudy outside in Berlin.

The next meeting was followed after the lunch break, which helped everybody to warm up and restore energy! We were well surprised to discover a small, but important community grey-water recycling center in the down town of Berlin managed by Mr. Nolde. This meeting was concerned to energy and recycling. Mr. Nolde explained all aspects of grey-water recycling in it’s three steps. Personally, I was surprised that there is another view to recycling of water in Germany, as it’s also an energy source!!! Overall, Mr. Nolde explained also water recycling challenges and new water concepts and regulations in Germany. The other discover was that this facility was managed only by one person and it was well automated and organized.

The second day started with a visit to the German Energy Agency (DENA), where Mr. Schmidt presented this very institution. The expertise, consultancy as well as developing strategy and monitoring of renewable energy sector in Germany.
The final visit was at the German Association of Energy Cooperatives, which is located next to the Brandenburg Gate. The participants could learn projects, tasks and functions of more than 800 cooperatives in the renewable energy sector of Germany. Having finished our visit, we said each other ‘see you again at CIPSEM’, since the majority of participants rested in Berlin or went to other cities such as Amsterdam and Paris for the weekend.

At last, I can say that we were warmly welcomed it was a very helpful visit at each organization during the two-day gateway in Berlin.

SC 69: Excursion to Dessau (German Environment Agency and Bauhaus)

By Adedoyin A. Adeleke (Nigeria)

It’s been learning and exciting time at CIPSEM since our course began. The diverse backgrounds of the 21 participants from 19 countries in the course have provided enriching insights on energy profiles (including their cultures) through the country reports. We have also had introductory lectures on renewable energy and energy efficiency which altogether have provided insights on trends, technologies and the policies driving them in Germany.
Then it was time to do some site visits, this time the German Environmental Agency headquarters in Dessau!  The about two and half hours’ journey by train provided opportunity to pass through other cities of Germany as well as villages. We realized that its global leadership in renewable energy, Germany also has fertile and expanse of land for agriculture.
On arrival at the Agency, we were taken on a guided tour round the building. What initially appeared to be a demonstration of architectural and artistic expertise would soon become a blend of arts and architectural design in a “model green building”. Our guide provided detailed explanations on the various designs and parts of the building as it relates to renewable energy and energy efficiency.

From the Agency, we proceeded to the world famous home of harmony of arts and craft, the Bauhaus in Dessau! We had another guided tour of the building and learned of its legacy in architecture since the 20th century. The 90-year old building which was a masterpiece in the 20th century architecture was designed in 1925 by Walter Gropius, a professor and an architect. The building was was unique with its glass wall, flat roofs and the no-main view design of the building which were peculiar at the time. The Bauhaus appears to be more than design but also a philosophy that pushed design on a new course: the Bauhaus provides an interface between User Experience, Sustainability and Innovation in building design.  From the Bauhaus, we retired to the hotel for dinner and night rest, courtesy of CIPSEM.
Next day, we had five insightful presentations at the German Environmental Agency (UBA). First was an introduction to the operation of the Agency.  It was exciting to learn of the reason for the location of the headquarter office of the UBA in Dessau instead of Berlin, the capital. We learned that all second place government institutions were asked to move to the interior to facilitate infrastructural development in 2004. Among other responsibilities, the agency supports Federal ministry for the environment, Nature conservation Building, and Nuclear safety (BMUB) and the Federal Ministry of Economy and Energy (BMWi)  “by providing scientific knowledge on energy questions and issues such as renewable energy”, collecting data, educating the public, implementing statutory provisions, among others. Thanks to Dr. Benno Hain for his presentation.
In his second presentation, Dr. Hain discussed policy and the institutional framework for Climate mitigation strategies and scenarios in Germany. He introduced the three levels of policy drivers for climate change in Germany: national (Energy Concept of Germany), regional (Climate and Energy Package of the EU28) and the global (International Climate Policy, UNFCCC). Very insightful!
Next was a presentation on the various bioenergy applications and their roles in sustainable development.  Jan Seven emphasized that though the use of bioenergy (traditional) is an ancient practice, their inefficient use results in resource depletion, air pollution and labour shortage.  He also itemized the risks and opportunities associated with modern bioenergy. According to him, averting the risks while taking advantage of the opportunities requires changes in current practices and strategies. Further, he discussed UBA’s activities for sustainable bioenergy development and support for the Global Bioenergy Partnership (GBEP).
Max Werlein also made a presentation on the “Energy Transition in Germany”.  He discussed the concept “Energiewende”, targets and the three policy goals driving it: economic efficiency, security of supply, and environmental compatibility.  After the lunch break, we had the last presentation by Jens Schuberth: “Policies for energy saving”.  Jens discussed the prospects and challenges of sustainable use of energy and energy efficient products. His lecture also provided insights on policies and strategies for promoting the construction of energy efficient buildings in Germany.
Overall, the excursion provided insights on the German energy system, targets and the policies drivers. Thanks to CIPSEM for facilitating the visit and special thanks for Andre for leading us on the trip!

The solar value chain and beyond

An important part of our short course on renewable energy sources and energy efficiency has been our visit to SolarWorld Freiberg.
All participants made good use of this opportunity to learn about the solar value chain including recycling of photovoltaic modules. We got to know current types and characteristics of PV-systems.
We also discovered what makes a good quality photovoltaic system. The wide range of short and long term benefits of high quality standards came as a surprise to some of us and illustrated well that lower up-front costs don’t necessarily lead to lower total cost.

Thanks to Mr. Handke for enthusiastically sharing his knowledge in an introductory talk, a guided tour, and extensive Q&A sessions.

After fortifying ourselves at the student restaurant we went on to explore mining history of the area and the natural beauty of minerals in the Terra Mineralia exhibition.
