3. Non-optimality of the structure of the energy supply system, which has developed without taking into account climate change; non-compliance with the necessary levels and modes of energy consumption, taking into account the indicated changes, which will lead to an overexpenditure of energy resources to provide consumers or the need to limit their supplies. 4. An increase in the cost of eliminating accidents at fuel and energy facilities. Figure 6.10. a generalized assessment of the impact of climate change on the energy sector and its consequences is given.
