Internalization of external economic effects on urban sprawl affected areas. An example of the Krakow Metropolitan Area, The study is a discussion on economic externalities, with particular emphasis on technological effects. Attention is also paid to the problem of internalization of economic external effects caused by movement (transport) in areas affected by the urban sprawl process. The research was conducted for all communes of the Krakow Metropolitan Area (KOM), as a result of which the value of: directly incurred financial losses and the value of lost time generated by the necessity of commuting and return in the space of KOM were presented.
The paper presents an analysis of the sustainable development of electricity generation sources in the National Power System (NPS). The criteria to be met by sustainable power systems were determined. The paper delineates the power balance of centrally dispatched power generation units (CDPGU), which is required for the secure work of the NPS until 2035. 19 prospective electricity generation technologies were defined. They were divided into the following three groups: system power plants, large and medium combined heat and power (CHP) plants, as well as small power plants and CHP plants (distributed sources). The quantities to characterize the energy effectiveness and CO2 emission of the energy generation technologies analyzed were determined. The unit electricity generation costs, discounted for 2018, including the costs of CO2 emission allowance, were determined for the particular technologies. The roadmap of the sustainable development of the generation sources in the NPS between 2020 and 2035 was proposed. The results of the calculations and analyses were presented in tables and figure
