Jean-Luc Salanave, Le développementfulgurantdes énergies solaire, photovoltaïque etéolienne,en ce débutde XXIe siècle, nous faitaussi expérimenter leurs inconvénients.La technologie en solutionnera bon nombre,mais intermittence etencombrementdemeurerontdes défauts majeurs de ces deux sources d’énergie tantqu’il y aura des absences de soleil ou de vent,etque 10 milliards de terriens auront besoin de surfaces habitables,cultivables etde forêts. Conclusion Pour satisfaire ses besoins énergétiques,l’homme ne disposera de rien d’autre que des trois seules forces fondamentales que la nature metà sa disposition :la force électromagnétique (énergies chimiques,combustibles fossiles,biomasse,photovoltaïque,…),la gravitation (énergies hydraulique,éolienne,inertielle,potentielle …) et les forces nucléaires (radioactivité,fission,fusion).

Barry Brook, Faculty of Science, Engineering & Technology, U. of Tasmania, Australia & Staffan Qvist, Dept. of Physics and Astrophysics, Uppsala University, Sweden: This documents the excellent French and Swedish nuclear power plant construction programs in the 1960s to 1990s. It then extrapolates to a prediction that the whole world could be on 100 % nuclear power within 25 - 34 years. This must assume that the rest of the world has similar government support and cooperation, similar stable, honest leadership, sound economies, industrial capabilities, education systems, etc. and that the construction companies and nuclear fuel demands for France and Sweden can be quickly increased to those of the whole world. It assumes that the world will use the same nuclear technology as the Swedish and French programs of the 1970s to 90s. In reality, it may take several hundred years to replace 50% of fossil fuels with advanced nuclear technologies that still need development and testing.

John Shanahan, Dr. Ing., Civil Engineer: With financial and management situations of Toshiba, Westinghouse, Areva, and GE in the nuclear power business, the world's capability to build new nuclear power plants has obviously been set back. China, Russia and South Korea are now the leading sources of new nuclear power plants. How France and the United States might make a come back is not known at this time. This is a simple estimate of how long it might take to have nuclear become 50% of the world's electric generating capacity. The conclusion is that it will probably take several hundred years to get to 50% nuclear electric generating capacity. This has significant implications for energy planning.

Fritz Vahrenholt, PhD Chemistry: Is the program in Germany to stop using nuclear power and switch to wind and solar energy more important than nature itself? BaZ: Sie haben die deutsche Energiewende als «Desaster» bezeichnet. Wieso? Fritz Vahrenholt: Zunächst einmal hat die deutsche Regierung nach dem Tsunami in Japan innerhalb eines Wochenendes entschieden, auf die Kernenergie zu verzichten, die bis dahin die Grundlast für die deutsche Industrie erzeugt hat. Die Regierung will seither diese gesicherte Energie durch schwankenden Strom aus Sonne und Wind ersetzen. Dass das nicht vernünftig ist, weiss eigentlich jeder.
