A large-scale expansion of offshore wind energy could lead to increased precipitation over offshore wind farm areas, while precipitation in adjacent coastal regions could decrease. This is due to wind turbines extracting part of the wind's kinetic energy and increasing atmospheric turbulence.
A new study reveals that offshore wind farms can create complex wake structures that interact with each other, affecting surface currents and sediment transport. The research suggests that turbines spaced farther apart can reduce turbulence caused by tidal wakes, leading to optimized wind farm designs.

The substances, which are widely used in everyday products, can be transported from inland sources to coastal environments through air masses and ocean currents.
A new study analyzes sediment cores from the North Sea, showing a significant accumulation of pollutants since the industrial revolution. The researchers found that the deposition of pollutants is linked to fine sediments transported by currents, causing a strong accumulation on the seabed.
Researchers found shifts in airflows and sea currents downwind of North Sea offshore wind farms, affecting plankton production and the food web structure. The turbines induce atmospheric wakes that redirect existing currents, leading to changed salinity distribution and mean temperatures.
Researchers have developed a tailored polymer membrane to encase micrometer-sized metal hydrides, improving the storage of hydrogen. The coating prevents surface oxidation and long-range separation of components, enabling more efficient energy storage.
Tropical seagrass meadows may not be as effective in absorbing carbon dioxide as previously believed. According to a new study, some of these ecosystems actually release more CO2 into the atmosphere than they store. This finding is significant for accurately calculating their climate protection potential.
Researchers found a decline in pollutant concentrations worldwide during the 2020 lockdown, particularly in Central Europe. The study attributed these reductions to the lockdown's impact on sectors like road and air transport, but noted that weather conditions also played a significant role.
Researchers have discovered that microplastics can serve as a transport vehicle for metals in the environment, accumulating and releasing these pollutants. The study found significant differences in metal accumulation between different types of plastics, with some metals attaching almost entirely to microplastics.
