Why and Wind Turbine ? During Summer 2005,
started to review additional environmental
options Always been looking at new ways to
manage the environment Open to Prevailing wind
- South Westerly Located at 103 meters above sea
level

Initial Concerns- Rural Location Noise Stanste
d Airport Planning permission
What did we do ? Research Internet Magazines
Papers Government info
Result of Research- Why did we want a wind
turbine ?

SAVE THE ENVIRONMENT MAKE LOTS OF MONEY FREE
ELECTRICITY WAY OF LIFE / GREEN IMAGE GUARANTEED
POWER SUPPLY
Use an untapped resources to supply power without
increasing environmental impact. Giving long term
environmental and cost benefit
There is NO single technology What is best for
your location and situation ?
Would we have undertaken the project if no grant
was available.
YES
