This paper is based on a talk given by invitation, to the “Energy Options Conference” organised by the Institution of Electrical Engineers at Reading University in 1987 [1]. The presentation was intended to give a broad view of activities in wind energy from the smallest scale (Watts) to the largest scale (Gigawatts). The paper is not intended for experts in wind energy, but should give a helpful impression of the new burgeoning field of wind energy engineering to those uninitiated into the subject.
