About the Authors
James Manwell is a professor of Mechanical Engineering at the University of Massachusetts
and the Director of the Wind Energy Center there.

He holds an M.S. in Electrical and Computer
Engineering and a Ph.D. in Mechanical Engineering.

He has been involved with a wide range of
wind energy research areas since the mid 1970’s.

These range from wind turbine dynamics to
wind hybrid power systems.

His most recent research has focused on the assessment of external
conditions related to the design of offshore wind turbines.

He has participated in activities of the
International Energy Agency, the International Electrotechnical Commission and the International Science Panel on Renewable Energies. He lives in Conway, Massachusetts.

Acknowledgments
We would like to acknowledge the late Professor William Heronemus, founder of the
renewable energy program at the University of Massachusetts.

Without his vision and tenacity,
this program would never have existed, and this book would never have been written. We are
also indebted to the numerous staff and students, past and present, at the University of
Massachusetts who have contributed to this program.
We would also like to acknowledge the initial contribution of the National Wind Technology
Center at the National Renewable Energy Laboratory (NREL), particularly Bob Thresher and
Darrell Dodge, in their supporting the revision and expansion of the notes on which this text is
based.
In addition, we appreciate the contribution of Rolf Niemeyer for looking into the sources of
information on the earliest windmills and Tulsi Vembu for his editing.
Finally, we would like to acknowledge the support of our families: our wives (Joanne,
Suzanne, and Anne) and our sons (Nate, Gerry, and Ned and Josh and Brian), who have all
inspired our work.
