Dear Professor Daniel kammen, Your blog on "How to of renewable energy" gives an end note on "The cheapest (financially and environmentally) energy is that which is not needed". It is quite surprising to hear that cost & economic viability of clean energy systems are not critical factors in consideration of renewable energy systems. It could be because of the technology defects of the present renewables under operation, which is compelling on such an option of not considering cost aspects. www.sustechinitiatives.com is a private initiative working on theme " Clean Planet Technology Initiatives for Sustainable Development". We could help the global community in meeting sustainable cost effective energy solutions. It is my pleasure to introduce and interact with front line professionals and policy bodies regarding viable techno development globally.
