The course informs about the basic theory of the environment and the ecology and the economy basics in the power engineering. The power engineering is closely related to the economy and the environment. In all power engineering-related areas, environmental and economic aspects can be identified. In connection with power engineering it identifies the main problems of the environment and presents methods and means of environmental protection and also shows corresponding laws etc. The course presents the basics of financial mathematic and the issues of the costs and the evaluation of the effectiveness of investments and others, which are the basis for understanding the connections between economy, ecology and power engineering.
Due to the innovation of curriculum, this subject was formed from previously separate - seemingly unrelated - subjects. For these historical reasons, the subject is partially taught as two separate issues, but there are efforts applied to interconnect individual chapters of both subjects.

In this course, the focus is on mastering the basics of financial mathematics that are fundamental for all other economic-energy calculations. Knowledge of issues such as interest rates, discounting and time value of money is crucial for understanding as well as successful completion of economic subjects in the master studies. Similarly, it is important to learn the basic rules and principles of ecological thinking and connections between ecology and power engineering.

In this course, emphasis is placed on both the numerical exercises in which students learn various methods of financial techno-environmental calculations, and the exercises and computer laboratories where the series of practical exercises and case studies, contributing to a better understanding of the topic, are solved.
