Free Energy e-learning

www.leonardo-energy.org offers free webcasts and webinars on sustainable energy.  I tried out 2 introductory courses on PV systems and Distributed generation.  The Information was very basic, good enough for novices in the renewable energy systems.  This was basically something like a powerpoint presentation with a voice over. They have webcasts for harmonics, lighting, renewable energy.  They also have webinars to discuss updates on specific technologies and issues.  Free e-books are also available in this site.  I think every sustainable energy advocate must check this site regularly
