Blockchain and other DLTs hold great promise to help solve key energy challenges. The growing number of connected devices and distributed energy resources is adding further complexity to the rapidly evolving energy system. Blockchain may play an integral part in connecting consumers, electric utilities and third parties to these devices and the wider system, in a more secure, efficient, and distributed way.

Energy saving is a major policy objective worldwide and in the EU in particular. Evaluating the convenience of energy-efficient investments, however, is complex. This paper aims to apply stochastic Life Cycle Costing to assess the economic value of energy-efficient building retrofitting investments. The proposed approach investigates how macroeconomic variables affect such an evaluation by explicitly taking into account their interdependent stochastic nature.
