Energy is an important part of the world today. Without energy production is impossible, development is impossible, life itself is impossible. Any activity is somehow connected to the energy industry. The future development of the world depends on progress in the energy sector. Existing problems in the energy industry are related not only to environmental pollution, but also to the consumption of limited natural resources. This becomes even more important in the future as the population grows. It is necessary to think about how we can control the impact of energy industry on nature and people? Can society maintain its current level of energy consumption? What resources can we use? In this course we will talk about energy, its impact on the environment, study in detail all components of the environmental safety system and find out how this system can prevent future environmental disasters.
