Daniel Michaels, writer for the Wall Street Journal: There are eight widely distributed major sources of energy for humanity: solar, wind, hydro, bio-mass, fossil fuels, uranium and thorium nuclear fission and fusion. Solar heats the Earth to livable temperatures, evaporates water from the oceans and drives the wind. Wind carries evaporated ocean water over land and drops it as rain and snow to enable plants to grow and for drinking water. Bio-mass has provided fire for heating, cooking and industry since the beginning of civilization. Bio-mass can only support limited population and life is pretty miserable with this energy source. Fossil fuels and fission from uranium and thorium enable tremendous advances in technologies and support many more people. Fission can provide all of humanity's energy needs for a very long time. Fusion, the energy in the sun could provide all the energy we need. Can we master it? If it is so close to being realized, why is it being left to small startup companies? At lease one physicist and one nuclear engineer think that fusion is not close to ready for commercial use.

S. Fred Singer, professor emeritus at the University of Virginia and director of the Science and Environmental Policy Project. Gerald E. Marsh, a retired physicist from Argonne National Laboratory - Many people believe that wind and solar energy are essential for replacing nonrenewable fossil fuels. They also believe that wind and solar are unique in providing energy that’s carbon-free and inexhaustible. A closer look shows that such beliefs are based on illusions and wishful thinking.

Michael Dittmar, physicist CERN, Conseil Européen pour la Recherche Nucléaire: - The worries about existing and potential problems with our oil, gas and coal supplies for our industrial based way of living have certainly increased.

However, people enthusiastic about large scale technology, especially with some background in physics, are pointing quickly either to nuclear energy or to large scale solar power projects as possible solutions to such worries. Such views are supported by most economists and politicians who propose that one only needs to invest trillions of dollars to manage potentially existing problems with our fossil fuel based energy civilization. It is assumed that the intelligent investment of money will be sufficient to solve the problems with nuclear fusion and make it available either directly on our planet or indirectly using solar energy. Such views about the future use of energy are often lacking the relevant facts about today’s energy use and existing technological constraints. Instead, the preferred form of discussions seems to be dominated by theoretical and hypothetical ideas about unproven concepts with unknown capital costs.
