The present paper presents different sources of energy. Energy of source, converted in vehicle engine, is transferred to the vehicle. Energy conversion, carried out in the engine, determines the kind of engine to be used in planetary and cosmic vehicles. All energy sources available on Earth are presented, supplying different forms of energy, used in planetary and cosmic vehicles. Energy of solar radiation is divided into two groups, used in land and cosmic vehicles. A method of using energy of solar radiation in planetary and cosmic vehicles, using solar batteries composed of photovoltaic cells, in which electric current is generated. Attention is drawn on hydrogen as source of chemical energy. Attention is drawn on the possibility of using nuclear energy in on-board reactor of rocket motor, using heat for heating working medium. It is emphasized that there are other energy sources in the Universe, the use of which is still subject to theoretical concepts. These are: energy of magnetic and electric fields and gravitational energy.
