Begging the Mods forgiveness, but I thought this was worthy of a standalone discussion. Imagine, if solar and wind were the cheapest and most effective way to provide power. Based on his calculations, University of Delaware's Wilett Kempton believes that could be the case. Part of it is based on a cooperative model of sharing wind and solar resources over a wide area, part of it is due to the cost of not paying externalities (like the costs associated with fossil fuels in terms of clean-up, health care, etc.)
Imagine if he's right and that if he exercise the will to get it done how much better off we might be.
Give him a listen and tell me what you think. Personally, I think if we can get it done it would make a great Christmas and New Years gift to us all and prove even further that the Mayans were wrong.
