The Front CoverBecause wind turbines operate in the natural atmosphere, high-resolution weather modelling is a powerful tool to help wind nergy projects succeed throughout the project life cycle. When properly applied, such modelling helps to optimise wind farms by reducing the uncertainty associated with the spatial variability of wind flow across the site. In the article on page 6 written by ArcVera Renewables you can read more about mesoscale and microscale modelling for wind energy applications.

The Front CoverHigh cost of licensed micro-siting software, a lack of reliable ground-based wind resource data and difficulty assessing geographically morphed areas make it challenging for project developers in Nepal to perform preliminary siting and tangible evaluations of large-scale wind projects. The article on page 7 elaborates on a necessitydriven framework for wind farm siting and sizing that can process freely available projectspecific parameters, geospatial data and factual information to identify project locations and produce quantitative figures.

The Front CoverFor wind turbine blades, generally two main root connection types exist to connect the rotor blade to the hub of the turbine: the T-bolt connection or bushing technology. Where for small size rotor blades both connection types are frequently used, for the large multi-megawatt turbines the bushing connection technology is becoming very interesting because of the potential to have longer blades with smaller roots. In the article on page 7 the bushing connection is discussed. Publisher's NoteEuropean Commission makes fighting climate change central to Europe’s economic recovery Features

The Front CoverWhile the need for renewable energy grows ever stronger and the energy market exploits wind power, the locations available for building wind farms without impacting airports and military bases due to radar interference are rapidly dwindling. Trelleborg Applied Technologies is developing radar absorbing materials for stealth wind farms to unblock gigawatts of wind turbine potential currently under objection across the world. You can read more about it in the article on page 7. Publisher's NoteWill the wind energy industry for once not be hard hit by a global crisis? Features

The Front CoverA growing number of wind turbines are operating in the second or third decade of their lifetime. As owner of 20-year-old Micon turbines in Germany the authors of the article on page 7 describe the possibilities and solutions for operating these wind turbines cost-effectively with the current low market prices for electricity supplied by wind turbines in Northern Europe. The picture on the cover is from the windfarm Lehe (Niedersachsen, Germany) where a TW 600a was replaced by Enercon E141. Publisher's NoteCOVID-19 and its impact on the wind energy Features

The Front CoverAn increasing number of wind turbines are approaching the end of their service lives. As a result, operators are being confronted with the crucial business decision of whether to decommission, repower or continue to operate their assets. One of the key factors affecting these decisions is the evaluation of the physical condition of the turbine. In the article on page 7, TÜV SÜD describes the methods, requirements and results of a lifetime extension assessment.. Publisher's NoteLaunch of photo contest and new guest writer Features
