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

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

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)
Charge Controller
