Project
“See the Need, Take the Lead”

Project Specifics


Modest reduction in campus CO2 output by
3,500 to 5,900 lbs. per year because of the wind
turbine.
Due to location specifics, it is estimated that the
turbine will generate 3,000 to 5,000 kilowatthours which is enough to power an new, energy
efficient home for 12 months. The data logger, at
the base of the tower, will collect data on wind
speed, wind direction and kilowatts produced.

What is tidal energy?
Tidal energy is one of the oldest forms of energy used by humans.
Indeed, tide mills, in use on the Spanish, French and British coasts,
date back to 787 A.D.. Tide mills consisted of a storage pond,
filled by the incoming (flood) tide through a sluice and
emptied during the outgoing (ebb) tide through a water wheel.
The tides turned waterwheels, producing mechanical power
to mill grain. We even have one remaining in New Yorkwhich worked well into the 20th century.
