Ekonomiczne i ekologiczne aspekty pozyskiwania energii w energetyce cieplnej

Abstract

In the article were presented the results of the analyses devoted to comparison of the costs of heating the residential buildings, taking into consideration fuel oil, natural gas, hard coal, fuel wood, heat from MPEC and electric energy in the II tariff. The calculations were made on the basis of the cost of investment in the devices, the cost of energy carriers and the operation period of the devices. Apart from the economy, the second relevant factor determining the utilization of the considered energy carriers should be ecology. In the case of heating the residential buildings with fuel oil, natural gas, hard coal and fuel wood one could easily calculate the volume of emission. It’s much more difficult to define the influence of heat from MPEC and electric energy on the environment, because it will depend on, among others, the kind of carrier used at their production.
