How is the global state of introduction of Renewable Energies including PV Solar Energy Conversion? What describes the energy dangers of mankind in our times? The nuclear/ fossil energy economy dominates the global energy markets. It increasingly creates international conflicts because of the exhaustion of primary energy resources. Terrorist or military attacks against power stations and long power lines increase the vulnerability of societies. Conventional energies do harm to the health of people. This was shown recently by the magazine "Science", which predicted hundred thousands of deaths by fossil fuel emissions in the big cities. The conventional energies restrict the economies, mainly of the developing countries: most African states nowadays spend between 50 and 100 % of their total export income for the import of oil.
