IN Practice

IN PRACTICE summarizes the central results of a research project in a practical form on just a few pages. It is thus aimed specifically at the planning and approval practice at the various planning levels.

ProBat 7 – Intelligent wind turbine operation management for the protection of bats as a permit condition for wind turbines

The software tool ProBat 7.0 calculates bat-friendly cut-in wind speeds for onshore wind turbines (WT). This operational management helps to minimise the killing risk for bats (collisionr barotrauma) and allows a more efficient operation of the installations compared to blanket switch-on or switch-off requirements.



Nature and landscape conservation: GIS-supported scenarios for wind energy

The geographical distribution of the future expansion of onshore wind energy is one of the major controversial planning tasks. The new method funded by the Federal Agency for Nature Conservation enables the transfer of all aspects of nature and landscape conservation of relevance for wind power to a national GIS model for the first time. Thereby, an evaluation of different wind power expansion scenarios in terms of their risks of conflicting with nature and landscape conservation is possible. The analyses show that, for the 2035 target of roughly 270 TWh of energy from onshore wind turbines, there is considerable scope for expansion that is compatible with nature and landscape.



Bird flight diverters on overhead power lines – an expert convention proposal to take account of the species-specific protective effect in planning and approval procedures

Bird flight diverters on high-voltage lines reduce the approach and collision risks for birds. However, expert conservation examination of new construction projects still leaves uncertainty in assessing their effectiveness for individual bird species in practice. The new convention proposal makes the first assessment of the degree to which the constellation-specific risk (CSR) for 164 bird species can be reduced by the use of bird diverters.



Protection of birds and bats at small wind turbines

According to the Federal Immission Control Act, small wind turbines (WTGs) up to a total height of 50 m do not require a permit. Not much is yet known about the effects on birds and bats in particular. Two research projects funded by the Federal Agency for Nature Conservation (BfN) with funds from the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) are providing initial answers as to which factors as to which factors can contribute to a reduction in the risk of collision when selecting a site.

Nature-compatible heat transition

The broshure addresses the question of how nature conservation concerns can be integrated into the development of future heating and cooling supply and presents six basic principles for a nature-compatible heat transition. The publication is primarily aimed at municipalities, planning practice and households. It is also based on the results of a research and development project. In this project, the researchers examined the efficiency of land use and the effects of the technologies on nature and the landscape. Among other things, they looked at the use of biomass, (large-scale) heat pumps, solar thermal systems, heat networks and heat storage systems.  The R&D project was funded by the BfN with funds from the Federal Ministry for the Environment.
