How Do Wind Turbines Work? Department of Energy

The terms wind energy or wind power describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can

1. Background/Introduction Geometry of the Twisted

Background/Introduction. There are two major subtypes of VAWTs lift-based Darrieus designs which utilize airfoils and drag-based Savonius turbines which use large cups for blades. Both designs were first developed in the early 20 th century. The animation below depicts the basic operation of the three primary types of modern wind turbines.

POWER GENERATION USING STRAIGHT BLADED DARRIEUS

INTRODUCTION The wind turbines can be divided into two groups of turbines depending on the orientation of their axis of rotation, namely the most common horizontal axis wind turbines (HAWTs) and vertical axis wind turbines (VAWTs). It is an augmented version of Darrieus Turbine with straight blades instead of using curved blades. The H
