The Energy Atlas.NRW with the solar and heat cadastre
Published
Like the heat register, the solar register is part of the Energy Atlas.NRW, which provides comprehensive information on renewable energies in North Rhine-Westphalia. In addition to the current stock, potential for the further expansion of renewable energies is also presented.
In the solar register, the potential, yields and economic viability of solar energy (photovoltaics and solar thermal energy) can be calculated individually for each of the approximately eleven million building roofs analysed in NRW. The data basis for the calculation is updated regularly. Homeowners, owners of commercial properties, housing associations, local authorities and energy suppliers can thus obtain information independently, free of charge, simply and quickly about the possibilities for using solar energy on their roofs. The area-wide heat register provides information on renewable and energy-efficient heat sources as well as existing heat sinks in NRW. It provides an overview of possible alternatives for supplying heat to properties and neighbourhoods, or for integrating renewable and efficient sources into existing heating networks.
"With the EnergyAtlas.NRW, LANUV offers local authorities optimum guidance in the implementation of the energy transition on the ground. The data bases from the EnergyAtlas.NRW help to initiate municipal climate protection projects in the electricity and heating sectors, but also to document the further expansion of renewable energies at municipal level", explained Antje Kruse from the North Rhine-Westphalia State Office for Nature, Environment and Consumer Protection.
State aid for housing construction drives up prices, but does not bring more housing. This is how an assessment by the DIW (German Institute for Economic Research), Berlin, can be interpreted.
Over the last 150 years, the concentration of greenhouse gases in the atmosphere, which are responsible for climate change, has risen sharply. Germany has set itself the goal of becoming largely greenhouse gas neutral by 2050. The great importance of municipalities in achieving these climate protection goals and the important role played by the increased and responsible use of wood became clear at the award ceremony for the 2016/2017 HolzProKlima municipal competition in Baden-Württemberg.
The award ceremony honoured cities, municipalities and districts that have made a conscious political decision to contribute to climate protection in their region by increasing the use of wood as a renewable resource. The competition office received a total of 40 applications. Cash and non-cash prizes totalling 20,000 euros were provided by companies in the wood-processing industry.

Climate champion was the municipality of Frickingen. Baden-Württemberg's Forestry Minister Peter Hauk (CDU) honoured the winners of the municipal competition in person and thanked the organisers of the state-sponsored competition: "There is a great need for the climate-positive material wood, and the possible uses are becoming increasingly diverse thanks to innovations."
at the Sustainable Procurement Symposium in Dortmund on 26 August 2021
The Sustainable Procurement Day is a platform for exchange for procurers and decision-makers from municipalities, private and public institutions as well as churches and companies. Federal Environment Minister Svenja Schulze is the patron. The Agency for Renewable Resources e. V. (FNR), project management agency of the Federal Ministry of Food and Agriculture, will be represented with a workshop on the topic of "Public building and renovation with wood - the right way to tender for timber construction projects" in addition to the stand "The renewable office".
Climate-friendly construction, renovation and insulation with sustainable materials is becoming more and more common practice in public building projects as well. Sustainable municipal management includes the building sector - keyword climate-neutral municipality/administration. Wood as a building material has become the focus of attention in recent years, and there are many reasons for this: Wood stores CO2Depending on the degree of prefabrication, it can considerably shorten construction times and, due to its low dead weight, is ideal for adding storeys, e.g. in the case of redensification in urban development.
However, in order to successfully launch public timber construction projects, a targeted award procedure is crucial. This is because even during the planning and tendering stages, it is important to take into account the significant differences compared to solid construction, e.g. in terms of timing, the submission of building applications and the timely involvement of timber construction expertise.
Participation in the symposium and the FNR construction contracting workshop is free of charge. Registration is required.
The workshop complements the current FNR seminar series "On course for the future: public building with wood", which is carried out within the framework of the Charter for Wood 2.0 and in cooperation with the municipal umbrella organisations and the Wood Information Service. The offer is free of charge. Further information on the seminar series can be found at: https://veranstaltungen.fnr.de/holzbau.
Berlin: On 4 May 2018, BUND presented a shutdown plan for nuclear power plants (NPPs) and coal-fired power plants. This analysis shows that the decommissioning of the most climate-damaging coal-fired power plants by 2020 and a significant acceleration of the nuclear phase-out in Germany are possible without jeopardising security of supply. "The shutdown plan is a call to action for the political actors to finally take action," explains BUND Chair Hubert Weiger at the presentation of the shutdown plan in Berlin.
In the shutdown plan, BUND has drawn up a concrete performance balance and names power plants as well as annual figures for the shutdown. The focus is on the years 2020 and 2023. This period is considered to be a particular challenge for supply security, since on the one hand it is the legal date for the phase-out of nuclear power. On the other hand, a good half of the coal-fired power plants must be taken off the grid in order to achieve the German climate target for 2020.
The BUND shutdown plan shows that this is possible and that significantly more coal-fired power plants can be taken off the grid in the short term than has been discussed so far, and that this can also be combined with a significant acceleration of the nuclear phase-out. As a result, the power surplus in Germany is declining, but the supply remains guaranteed even in hours without sun and with little wind. "In the first quarter of 2018, Germany exported on average the electricity production of five large power plants. Against this background alone, it is surprising that the new federal government has not agreed on the short-term decommissioning of the most climate-damaging coal-fired power plants," says the BUND chairman. "We want to show with our analysis that much more is possible if the political will is there."
The BUND shutdown plan shows that security of supply can be ensured if politicians do not continue to wait, but actively promote the energy transition in parallel to the shutdowns. The calculations of the power balance are mainly based on values from, for example, the Federal Network Agency or the transmission system operators. Deviations and other assumptions are justified. "With our analysis, we want to provide an important impetus for a transparent debate within the framework of the amendment to the Atomic Energy Act and the coal phase-out commission that is being constituted," explains Weiger.
In a shutdown list for coal-fired power plants, BUND proposes the units that would have to be taken off the grid first in order to achieve the 2020 climate target. It concerns all larger coal-fired power plants that were connected to the grid before 1990, in order to reduce the coal capacity on the electricity market to 20 gigawatts. As a new measure to enable a socially acceptable coal phase-out and to safeguard security of supply in extreme situations, the environmental association proposes the introduction of an additional coal phase-out reserve of six to eight gigawatts.
"The Paris Climate Agreement requires the phase-out of coal before 2030. The federal government is responsible for achieving the climate targets, it must enshrine the phase-out in law and ensure a just structural change. To achieve the 2020 climate target, it must now launch an immediate programme. Waiting any longer is irresponsible," continued the BUND chair. Due to the inactivity of climate policy in recent years, the German "climate problem" has become increasingly acute. According to the latest emission forecasts, the German climate protection target for 2020 will be missed by ten percentage points.
At the same time as the coal phase-out, the nuclear power plants can also be taken off the grid more quickly than required by law. The seven nuclear power plants that are currently still connected to the grid represent a constant safety risk for the population and must be decommissioned as soon as possible. So far, however, the federal government does not want to use the amendment to the Atomic Energy Act to really accelerate the nuclear phase-out. "BUND demands an immediate nuclear phase-out. At the very least, the current revision of the Atomic Energy Act must be used to legally prohibit further transfers of electricity volumes," says Weiger. Without this transfer, the nuclear power plants would run for a total of ten years less and the production of 300 tonnes of highly radioactive nuclear waste would be avoided.
Getting out of nuclear power and coal and still securing the energy supply - this is possible if the energy transition is driven forward. "It is a matter of further expanding renewable energies with commitment and creating the energy-economic framework conditions for an energy turnaround that is essentially based on wind energy and photovoltaics," says Weiger. This means an expansion of flexible decentralised CHP power plants, a reduction in electricity consumption, optimised utilisation of the electricity grids and a significant increase in the possibilities for load reduction.
