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

A few days ago, I read in the dotearth blog of the NY times about Google's investment in Enhanced Geothermal Systems (EGS). The technology is quite interesting. Typical geothermal systems utilize natural steam pockets near volcanoes. EGS involves drilling into the earth's crust about 4km's. Water is then pumped into the drilled area to open fissures. Heat from magma would result to steam build up in the fissures. During operation, there would be inlet pipes for water and outlet pipes for steam. Harvested steam would be transported to a turbine and generate electricity. EGS would make geothermal power feasible almost anywhere in the world. This would be a better alternative to coal fired power plants, one of the main causes for the climate crisis.

This is a photo of an awesome windfarm in Joshua Tree, CA. Taken in 2000 during a long drive from Phoenix AZ to San Diego CA along Interstate 8. While we have this in Ilocos, we still have to see this in a larger scale. The Philippines has a potential of 7404MW of utility grade wind power. Today we only have about 25MW operational in Bangui Bay.
