How much wind energy does the atmosphere generate, and how much of it can at best be used as renewable energy? This review aims to give physically-based answers to both questions, providing first-order estimates and sensitivities that are consistent with

Wind Turbine Performance in Very Large Wind Farms: Betz Analysis Revisited
The theoretical limit for wind turbine performance, the so-called Betz limit, arises from an inviscid, irrotational analysis of the streamtube around an actuator disk.

The Betz limit and the corresponding thermodynamic limit
The Betz’s limit for the maximum efficiency of an ideal wind turbine imposes a maximum value of about 60% on the conversion of the kinetic energy of an airflow into work. In this paper, we analyze the reason for this value because, from a thermodynamic point of view, it can be 100%.

Optimal relationship between power and design-driving loads for wind turbine rotors using 1-D models [PDF]
We investigate the optimal relationship between the aerodynamic power, thrust loading and size of a wind turbine rotor when its design is constrained by a static aerodynamic load.

Numerical study of ducted turbines in bi-directional tidal flows
Installing a turbine in a duct generally increases the flow through the rotor. If there is flow confinement due to limited water depth, the presence of lateral boundaries, or the presence of adjacent turbines, a further flow enhancement through the rotor

Wind Turbine Power: The Betz Limit and Beyond [PDF]
With a severe energy crisis facing the modern world, the production and utilization of ener‐ gy has become a vital issue, and the conservation of energy has acquired prime importance. Energy production and consumption are directly related to everyday life in much of human society, and issues of energy research are extremely important and highly ...
