The energy sector of the USSR and later on that of Russia rested on and has been founded on a powerful system of the centralized electricity and heat supply making use of conventional energy sources and is associated with considerable transportation expenses and losses. The price advance on conventional energy sources, that has been observed lately, opens the door to the arrangement of competitive conditions for energy supply on the basis of unconventional and renewable energy sources. Integration, in the use of a number of kinds of renewable and non-conventional energy in a single power supply system, is one of the feasible tendencies to solve the issues. A worthwhile and highly efficient power complex is possible to set up comprising a geothermal circulating system (GCS), windpower plant, and solar station,which results in the removal of drawbacks of any of energy sources. Power engineering in the twenty first century inevitably will entrust humanity with a monumental task. It will force the resolution of the problem of rational and environmentally friendly conversion of sources of renewable and nonrenewable energy. The strategy of development of the human will rely on the idea of the balanced coexistence of an individual and his environment. The industrial and technological revolutions that took place in the 20th century as well as the informational revolution that is under way based upon intensive use of natural resources of combustibles. Conscious awareness of environmental friendliness, sustaining ecological balance and environmental management were stated in basic documents adopted by international forums that took place in Rio de Janeiro, Kyoto, Harare, etc. and emerged by the end of the millennium.
