Goals

Wind EnergyWhat wind is

Wind power generation- Wind Turbine

Advantages and challenges

Personal Use

WindHow it’s formed

–Uneven heating of the atmosphere

–Irregularities of the earth’s surface

–Rotation of the earth

How wind flow patterns are determined

–Earth’s Terrain -Bodies of water -Vegetation

•How it's captured to create electricity

–Wind Turbine

Wind Turbine

What it is-Device that converts kinetic energy from wind into mechanical energy.

Advantages and Challenges

PROS

●Renewable energy●Abundant●Low-priced long term

CONS

●May not be cost competitive●Higher initial investment●Wind is inconsistent

Personal Wind Systems

● Provides energy for personal use

●Requires consistent Wind around 9mph for best use

Skystream 3.7 Wind Turbine

Educational opportunities on Wind

Rethinking Wind Energy

Horizontal Axis Wind Turbine (HAWT)

Traditional Design Commercially used Quite Expensive Needs to be directed into the wind

Vertical Axis Wind Turbine (VAWT)

Recently popular Used more on the residential level Lower Cost No need for direction

Micro Hydro Power System

Convert potential energy from water flow

Great alternative energy source Turbine Generator electricity Head and flow of stream Constant AC power

www.homepower.com

Energy Output

P = Q * H * e * gP = Power at generator terminal (kW)Q = Volume flow in pipeline (m3/s)H = Head (m)e = efficiency g = 9.81 m/s2 (gravity constant)

Head- vertical distance the water fallsHigher heads require less water to produce a given amount of power.

Power Pathway

Where Is The Power?

Controlling the power

Preventing overcharge Preventing

Reverse flowDid you know that Solar Panels remove charge from a battery at night?

Low Voltage DisconnectSolar Power Cut power at 80% diminished or 20% of total charge

Wind Keep constant load (Dump Load)
