The work highlights some aspects of thermal power plants impact on the environment, which are basically of a social nature. It concerns problems of reducing the emissions and their impact on population health.

Modern thermal power plants are complicated structures equipped with latest technologies. Among them there are systems for sulphur and nitrogen cleaning; systems of thermal and plasmothermal preparation, steam-gas diagrams, chemical complexes, system of gas utilization, gas-turbine, steam turbine; coal gasification and other. Besides coal power units can release two or more kinds of products.

At the same time modern power plants have a multifaceted impact on various spheres of the society. They comprise power systems with a great number of ecological, social and technological connections.

Among the varieties of connections of a modern power unit with the environment, the one connection that should be singled out is the impact on health interpreted through the data of public health. However, it is shown that this influence is mutual.

The point is: the emissions (ashes, sulphur and nitrogen) pollute the air in the area where power units are located, worsening the health condition in the population nearby. The costs paid for treatment and rehabilitation might be seen as factors reducing efficiency of the power unit or a inefficient choice of technology. The annual medical costs are correlated with a general criterion of efficiency and in the process of optimisation influence on the decision to move the into an area with a lower density of the population and also to choose an optimal profile of the power unit. In such case as a criterion for optimisation an indicator of profitability of the power unit is viewed with regard to this or that new technology.

Comparative analysis of different heating power blocks in the range of capacities 50…250 MW leads us to the following conclusions:

• Deviations in the costs on restoration of ecological and social infrastructure with account of health care factor or without it does not depend on the unit capacity, its initial parameters and a type of technological scheme and lie in the range of 1:2,5-3,5.
• Really operating power units and boilers do not match these numbers even in case of using natural gas as a fuel and location on a windy side of heat consumers, which calls upon new approaches for choice of a site for energy sources near residential areas.

In conclusion it is worthy to note that newly arising ecological problems challenge the society. This task is still to be solved.

The report shows options for solving a number of problems but they are not claiming to be the true ones. At the same time the fact of the impact of the anthropogenic activity on the climate and health of man has been evident. As soon as the ways to reduce negative consequences of such activity will be found the longer can survive the technical civilization.
