I think the numbers you show us about "the world spending less on energy R&D than on pet food" probably will make (some of ) us think about the current world priorities. The numbers give some insights and possible hints on world policy directions. However the "claim" may need in-depth analysis. I think that the amount of the R&D dollars spent may not be proportional to the outcomes of the research. Does the R&D need the huge amount to generate good results for energy sustainability? Is the comparison meaningful? How?
