Unit 5 Overview

Wind turbines come in two major types: vertical and horizontal axis type wind turbines. Wind turbines can convert the wind energy into rotational movement by using blades that provide drag, least effective and lift-type airfoil, more effective.

Finding the right site for wind turbines is critical for its success. Power is proportional to the cube of wind speed. Let me say that another way: power will increase by wind * wind * wind. That is a lot more wind to move the turbine.

Wind turbines are generally sized in three categories: Small Wind 10kW or smaller, Small Commercial Wind 100kW or less, and Large Wind or Big Wind, which is rated in megawatts.In this unit’s Live Seminar, we will discuss the very real advantages of wind energy: a predictable source of energy, generation of local revenue from wind farms to local communities, and overall lower emissions from its electrical production.
