Alternative Sources

Wind Power
◦ No Fuel Required
◦ Can not run out of
wind

Turbines
◦ 3 Bladed rotors
◦ Up to 87 yards long
◦ Spin up to 200 mph

Wind Farm
◦ Hundreds of towers
or turbines
◦ 65 tons of
equipment
Uses electrolytes to store energy
 Able to absorb and release large amounts
of energy
 Stores energy from wind turbines

Vanadium Battery

Wind Power kites
◦ Fly like helicopters
 Mile or more into the air
◦ Long cord that energy can travel down
◦ Wind is stronger
Windmills in The Sky

Has 2 blades instead of 3 blades
◦
◦
◦
◦
Spans 44 yards
Lighter weight
Flexible blades
Hinged with downward positioned rotors
 Avoid blades smashing into towers
Turbine Prototypes
Can’t turn wind on or off
 If there is no wind, there is no power
 The cost of a battery back up system cost
almost 2.5 billion for about 250,000
people for 24 hours

Disadvantages
With rising prices, alternative sources are
needed.
 Possible source are: Wind, Turbines and
Wind Farms
 Using vanadium batteries to store energy
