Geothermal energy use is the perspective way to clean sustainable development of the world. Russia has rich high and low temperature geothermal resources and makes good steps in this direction. The development of the present-day world is impossible without large cities. At present, urbanization has become a truly global process whose rates and scales increase catastrophically. The gigantic concentration of people results in a multiple increase in the supplies of water, energy, and food to cities, which, along with an increased production and service, is responsible for the accumulation of a huge amount of polluted water and industrial and domestic waste in the city areas. This causes an aggravation of social, environmental, and economic problems in large cities. Under these conditions the problems of urbanization and municipal engineering take on an absolutely different social significance ñ they become part and parcel of the global problem of sustained development of the modern society. In this connection two important aspects could be considered: clean alternative renewable energy use and organization of environmental parks as demonstration of preferences and advantages of such energetic supply, which are very close. The concept of environmental parks on the territories of big towns and for reserved territories is under elaboration. Choice of the optimal system of nature-friendly energy support is based on use of the deep-thermal energy and other ecologically pure sources, depending on concrete conditions of the environmental park/aquapark, and takes into account all the environmental, economical and social factors. As a result the environmental passport of territories can be created. |
