    ewz involves citizens in further solar systems

    ewz offers people who want to actively participate in the energy transition the opportunity to acquire stakes in photovoltaic systems. This type of crowd financing enables the construction of new systems, for example on school roofs. According to a press release , ewz is offering a total of 4,000 square meters of new space for this purpose.

    Of this, 1,100 square meters of photovoltaic area are now available on the Falletsche municipal school building in Leimbach. The Rebhügel school buildings in Wiedikon, Kolbenacker in Seebach and Mattenhof in Schwamendingen will go online in the course of the year. A maximum of ten square meters of participation at CHF 250 per household can be purchased on the Internet. In return, customers receive 80 kilowatt hours of sustainably produced solar power from Zurich per square meter of participation credited to their electricity bills.

    The last square meters of participation are still available for the first large-scale high-alpine solar system in Switzerland, which has already been completed on the ewz dam in Graubünden's Bergell. Because the yield is more than twice as high as in the Unterland, both the participation price and the credit are higher there.

  • ETH model paves the way for the energy transition

    ETH model paves the way for the energy transition

    At the Energy Science Center ( ESC ) of the Swiss Federal Institute of Technology in Zurich ( ETH ), an interdisciplinary research group is working on the Nexus-e platform. It is intended to help answer the fundamental questions that the energy transition that has been adopted will raise for politics, business, science and society now and in the years to come. The project is supported by the Federal Office for Energy .

    As a video from ETH shows, Nexus-e is supposed to map the entire complex Swiss electricity system. “In order to find solutions for the future, you need more flexibility,” project manager Marius Schwarz is quoted in an article by the ETH. "With Nexus-e we want to provide a platform with which we can model different scenarios and thus facilitate the transformation of the energy sector in the coming decades."

    This transparent platform is supposed to be a kind of toolbox. Its flexible modules are intended to represent the Swiss economy as a whole and the electricity market as well as the electricity market, investments in decentralized and centralized energy systems, network security and network expansion.

    It also serves as a modeling infrastructure that is continuously used in research and teaching. This will make it a modeling platform for interdisciplinary research within the university. But it should also be used outside as a test environment and further developed. "We are therefore open to new collaborations in the academic field, but also with political decision-makers or representatives from industry," said ESC director Christian Schaffner.

  • Switzerland must accelerate the energy transition

    Switzerland must accelerate the energy transition

    Switzerland has set itself less ambitious goals for the energy transition up to 2020 and is likely to achieve them. This is shown by the third monitoring report by the Federal Office of Energy ( SFOE ). After that, the new renewable energies achieved an electricity production of 4186 gigawatt hours in 2019. The SFOE writes in a press release that the target of 4400 gigawatt hours in 2020 is within reach. But if the guideline value of 11,400 gigawatt hours is to be achieved in 2035, the annual additions must amount to an average of 451 gigawatt hours, one and a half times as much as in the past decade.

    The final energy consumption per capita is similar: the reduction target of minus 16 percent by 2020 compared to 2000 was already achieved in 2016. By 2019, minus 19.1 percent was achieved. But if the benchmark for 2035 of minus 43 percent is to be achieved, then the average annual decline would have to be minus 2.2 percent. In the past decade it was only minus 1.4 percent.

    The Energy Perspectives 2050+ published at the same time by the SFOE came to the conclusion that if Switzerland continued with the existing practice, it would fall far short of its climate target in the long term. Switzerland has committed itself to reducing its CO2 emissions to net zero by 2050. But with a “keep it up” it comes to a reduction in CO2 emissions of 30 percent compared to 2020.

    However, the Energy Perspectives 2050+ assume that Switzerland can achieve its climate target with the technologies that are already available or currently being developed. The investment requirement would be only 8 percent higher than a continuation of the previous practice, according to a BFE announcement . If the current practice were retained, a total of CHF 1,400 billion would have to be invested in energy infrastructure, systems, devices and vehicles by 2050. If the net zero climate target is to be achieved, it would be a good 1,500 billion Swiss francs.

  • Film about the Knonauer Amt energy region celebrates its premiere

    Film about the Knonauer Amt energy region celebrates its premiere

    The Knonau office is “ten years ahead of its time”, said Government Councilor Dr. Martin Neukom in August on the occasion of the tenth anniversary of the Knonauer Amt energy region. “A driving force for the energy transition,” said Andrew Darrell, a member of the New York Sustainability Advisory Board. He thought that the world should find out about this pilot project, writes the “Affolter Anzeiger”. Together with the Swiss Pro Evolution Foundation and WWF Switzerland , he initiated a film about the exemplary work of the Knonauer Amt energy region. It premiered on Thursday. Its title: ” Full of energy into the future – a region relies on renewables “.

    The film reports on the initiatives that the 14 communities in this region in the canton of Zurich have undertaken and are undertaking to curb climate change: the energy-saving house in Stallikon, where children can experience energy in a playful way, the planned solar power plant above the A4, the Circular economy of the biogas plant in Rickenbach, the above-average number of CO2-neutral wood district heating plants. In 2010 the municipalities integrated the key project Energy Region Knonauer Amt into the location promotion. Their goal is to generate 80 percent of their energy needs by 2050 themselves and with renewable energies.

    Numerous experts have their say in the film, including Andreas Fischlin, member of the Intergovernmental Panel on Climate Change ( IPCC ) and professor at the Swiss Federal Institute of Technology in Zurich ( ETH ). “We have the same CO2 concentration as 3.5 million years ago,” he warns. At that time, there was a tropical flora and fauna in Switzerland. ETH professor Anton Gunzinger advocates greater use of local energies. That ensures more independence and that more money stays in the regional cycle: “We need more tax offices in Switzerland!”
