It seems obvious to me that solar energy, being the primary source of energy for *most* life and a substantial contributor to all known physical processes, would be a good place to start. I believe that most other forms of energy production are based on conversion of materials or processes generated by solar radiation, including *sustainable* forms such as gravity and wind-driven events. The exceptions such as nuclear and geo-thermal are theoretically useful, but as with other potentially sustainable sources require a significant energy input and/or acceptance of resulting waste.
Let's face it. The technology has been developed for some clean and perpetually renewable energy production, and with proper funding and intellectual investment these and other technologies could be perfected. Ultimately, there must be an economical and cultural paradigm shift with regards to energy production/consumption and crossover to new technologies. Essentially, cheaply produced and highly-efficient photovoltaic systems [or similar technology] could be producing free energy for anyone, anywhere at anytime. I guess I have a question: does anyone out there have a educated/experiential reason to explain why this has not happened? RMK
