Wind Energy, Volume 28, Issue 8, August 2025.ABSTRACT The conventional Savonius wind turbine's power coefficient is comparatively low, which limits its efficiency. Because the power coefficient depends significantly on the blade design, this study investigates the potential of improving the turbine performance by modifying the rotor blade designs.

Wind Energy, Volume 28, Issue 8, August 2025.ABSTRACT Wind energy is the most mature renewable energy technology; however, its exploitation in cities is often met with skepticism. Thanks to their ability to operate at low wind speed regardless of direction, vertical axis wind turbines (VAWTs) offer an attractive opportunity for wind energy harvesting in cities. However, limited evidence exists on

Multi‐Rotor Systems: Can They Increase Economy‐Wide Benefits Compared to Traditional Designs?
Wind Energy, Volume 28, Issue 8, August 2025.ABSTRACT This short communication reports on the economic consequences of increasing the market share of potentially lower‐cost offshore wind designs. We use data on the projected levelised cost of energy (LCOE) for traditional horizontal axis wind turbine (HAWT) designs compared with an illustrative multi‐rotor system which could have lower costs ...
