We now have nine papers published in the special issue of Energies on energy transitions and economic change and there are more to come. The latest paper is by Robert Kaufmann on the end of cheap oil and the implications for the United States and the former Soviet Union. This was one of the invited papers. The other published so far was the paper by Steve Sorrell. Also recently published is a paper by James Kahn et al. on Brazil's plans for expanding hydropower and by Rodriguez-Molina et al. on the smart grid.
