Renewable energy is at the heart of government policy in most western countries as global warming and its causes rise to the top of political and public agendas.  At the same time, the public demand for further growth in communications and more mobility seems as insatiable as increased demand for energy.  But within these public aspirations lies a dilemma: wind turbines, the major source of growth in renewable energy, cause interference to radio communications upon which many telecommunication services depend.  Can these conflicts be resolved?  Radio engineers, recognising the importance of both renewable energy and radio communications are seeking ways to reconcile this conflict.
