The Author
Hugh Piggott runs his own successful windpower business from
his home on the beautiful, appropriately windswept, peninsula of
Scoraig, off the coast of Scotland. There he advises individuals and
companies at home and abroad on small to medium scale
windpower turbines and systems. He has been making windmills
for twenty years from scrap parts and teaching others how to do so,
for example on the Centre for Alternative Technology's twice-
yearly windpower course. His books are amongst the Centre's best
sellers. He has a wife and two children. He has also written
