Met a guy from Clingendael Think Tank at a talk I was giving, recently. He said fuel free energy (renewable) will kill fossil fuel energy business model. How can renewables make money if fuel is free. I looked at him puzzled and really didn't understand what the problem was. Isn't that what capitalism does, look for better model, creative destruction, etc. If fuel free is a better modal for jobs and environmental impact, what's the problem?
