Anne Spiegel, Minister for Climate Protection, Environment, Energy and Mobility: “Climate change can be measured and felt in Rhineland-Palatinate”

“The annual mean temperature in Rhineland-Palatinate has risen by 1.6 degrees Celsius since 1881, and the year 2020 was the warmest year in Rhineland-Palatinate in the last 140 years. Summer days, hot days and heat waves are becoming increasingly common. Climate change is noticeable and measurable in Rhineland-Palatinate. The increase in temperature also makes the frequency and intensification of extreme weather events more likely. This is currently painfully evident in the devastating disaster in mid-July in the north of Rhineland-Palatinate,” said Climate Protection Minister Anne Spiegel on the occasion of the publication of the new edition of the special issue “Climate Change – Developments to date”.

Using various climate parameters, this shows how the climate has developed in Rhineland-Palatinate from the start of measurements in 1881 to 2020. The Rhineland-Palatinate Competence Center for Climate Change Impacts carried out the necessary evaluations together with the State Office for the Environment. The current special issue thus updates the data from the first edition of the issue from 2018.

Suitable for:

• Solar carports have been around for a long time - a German pioneering achievement
• Solar carports – carports with solar roofs

“The consequences of climate change have different effects in the different parts of Rhineland-Palatinate. The regions in Rhineland-Palatinate in particular that are among the warmer areas, such as the Moselle Valley, Rheinhessen and the Vorderpfalz, are suffering from the increased temperatures and more frequent heat periods. Since the country's large cities are also located there, more than 40 percent of the population was affected by severe heat in extreme years such as 2003 or 2018," explained Dr. Ulrich Matthes, head of the Rhineland-Palatinate Competence Center for Climate Change Impacts. The federal government's 2021 climate impact and risk analysis, published a few weeks ago, also identifies the Upper Rhine Graben and Rheinhessen as regions within Germany in which the risks from heat and drought are already very high and will continue to increase.

New edition of the special issue “Climate change – developments to date” shows how the climate in Rhineland-Palatinate has changed by 2020

“For example, a new addition to the special issue is the drought index, which shows that the years since 2003 have been consistently too dry in Rhineland-Palatinate. The drought is already having a massive impact on the country's water balance. Falling groundwater levels, low water levels and dry streams in the hot summers show us the consequences of climate change. The groundwater recharge rate alone has declined on average by around 25 percent over the last 18 years compared to the years 1951 to 2002,” says Sabine Riewenherm, President of the State Office for the Environment.

“The data series show us that, in addition to climate protection, we also need to focus on adapting to the consequences of climate change. With the Competence Center for the Effects of Climate Change and the State Office for the Environment, Rhineland-Palatinate is well positioned to recognize the consequences of climate change and develop adaptation strategies for the state,” concluded Minister Spiegel.

With the climate change information system (www.kwis-rlp.de), the Rhineland-Palatinate Competence Center for Climate Change Impacts offers comprehensive information and data about climate change in Rhineland-Palatinate and its effects on people and the environment. The integrated adaptation portal provides citizens, companies and municipalities with assistance in adapting to the consequences of climate change.

Anne Spiegel, Minister for Climate Protection, Environment, Energy and Mobility: “New studies provide important inspiration for how the energy transition can be implemented.”

The energy transition plays a crucial role in the goal of climate neutrality for Rhineland-Palatinate. In order to support the energy policy strategy, the ministry commissioned two studies - the flexibility and the decentralization study - the results of which are now available. “Climate protection and the expansion of renewable energies are a challenge for society as a whole. In order to accompany this process, it is important to back up the expansion with scientific results. The studies now presented provide important information and show us ways for future action,” explained Climate Protection and Energy Minister Anne Spiegel.

One focus of the Rhineland-Palatinate flexibility study carried out by a consortium made up of the BET Office for Energy Economics and Technical Planning GmbH, Aachen, and the Wuppertal Institute is the frequency and extent of surplus electricity generated from renewable sources, as well as shortfalls in Rhineland-Palatinate over the years will occur in 2030, 2040 and 2050. In doing so, the ministry is also implementing a point from the catalog of measures for the Rhineland-Palatinate climate protection concept. “The study shows: Given the expected technological developments in the energy industry, neither the expansion target of 100 percent renewable energies nor the country's current climate protection goals will lead to significant electricity surpluses. “This is an important result because there is no risk of significant shutdowns of renewable energy systems in Rhineland-Palatinate in the foreseeable future,” said Minister Anne Spiegel. In the scenarios for Rhineland-Palatinate, a maximum of 7 percent electricity surpluses can be expected in 2050. Despite overall small electricity surpluses, the expansion of renewable energies is leading to a growing number of hours with electricity prices close to zero or negative prices. The study shows which flexibility options can be used to compensate for electricity fluctuations in an economically sensible way. For this purpose, so-called “use cases” from various consumption areas were examined. “The necessary flexibility options are available: Industrial processes in particular, from district heating to public transport, offer considerable potential for using electricity from renewable energies cost-efficiently and making important contributions to the decarbonization of our economy,” says Spiegel.

Thanks to renewable energies, electricity generation takes place more locally, i.e. in a decentralized manner. There are already a large number of new producers with comparatively small generation plants, instead of the previously dominant large fossil and nuclear power plants near metropolitan areas. The decentralization study prepared by the Öko-Institut in Freiburg, Energynautics from Darmstadt and the Würzburg Environmental Energy Law Foundation revolves around the topic of decentralization of the German electricity and heat system. It provides an inventory of decentralized concepts, what advantages and disadvantages they offer and where there are opportunities for optimization. Based on the results, the study organizers have created a roadmap that describes the path to a decentralized energy system in Rhineland-Palatinate by 2050. “Decentralization opens up the producer market and enables participation. This must be supported and strengthened politically. As the decentralization study shows, this could happen, for example, at the federal level in the form of a strategy for decentralized electricity generation by so-called prosumers - that is, market participants who both generate and use electricity," says Spiegel. The combination of electricity generation and heat will also become increasingly important. The study shows that heat pumps, heat networks and municipal heat planning will be important building blocks for the combined electricity-heat system of the future. The study also found that, in addition to the decentralized concepts when optimizing the electricity system, centrally organized electricity trading should be maintained in order to enable the greatest possible competition.

• Covered solar parking spaces as a bridge to company roof systems
• Solar carports are a profitable investment

“In order to stop the climate crisis, we must act ambitiously at all levels today rather than tomorrow. There is still a lot to do. The task for the next few years must be to make the flexibility of the network usable and to lay the foundations for further expansion,” explained Minister Anne Spiegel in conclusion.

The demand for electric vehicles is increasing. The population has increased more than fifty-fold worldwide since 2012. In 2007 there were a total of 8 new registrations of electric cars in Germany. 2019 194,163 new registrations of electric vehicles! From January to May 2021 there were already 115,296 new registrations. The trend will continue to develop accordingly. Solar carports are already interesting investment goods. This also means an increase in the attractiveness of the production and company location for personnel and customer development.

Suitable for:

• Plan solar carport

A solar carport alone is not enough. Fundamental questions need to be clarified. Should the energy generated be fed into the grid or parked in energy or electricity storage? What are the load profiles, the technical connection conditions, number of charging stations, vehicle downtime and ultimately the specified total PV output? Will the charges be recorded with the company if the employee charges their company car from home? These are questions that we will have to deal with in the future. It is different from what we are used to today.

• Charging infrastructure for electromobility in Germany
• Electromobility is coming slowly, but it is coming
