Sažetak
The aim of this paper is to provide an analysis of the determinants
of economic efficiency and to assess the prerequisites for
the energy security of smart cities. The main methods of the
paper include an economic analysis of the infrastructure improvements
that result in reducing the energy demand of the smart cities
represented by the intelligent light-emitting diode (LED) street
lighting system. Smart LED streetlights are getting increasingly
popular in the world’s major metropolises as one of the leading
components of the “smart” city. We compare the efficiency of
LED street lighting used in smart cities with a commonly used
lighting system based on sodium lamps. Our results demonstrate
that LED street lighting system can significantly reduce the
energy demand of any modern city. Moreover, we show that
smart grids might help distribution systems within smart cities to
better integrate intermittent renewable energy sources such as
wind and solar. The main research novelty of our study compared
to previous studies from the literature is the estimation of net
profit (NP), Net Discounted Savings (NDS), as well as the total savings
(TS) using the example of an average European metropolis.
Our findings show that there is a need for better management
including strong networks of leaders to drive smart city policies
and investments and to cover wider city areas with economically
sustainable projects and plans. In addition, our findings yield that
smart city projects should aim at finding solution for smart connected
local energy storage systems to support more renewable
energy sources on the power grids. Our results might be of a special
interest for city planners, local government stakeholders, as
well as urban policy makers dealing with planning and managing
smart cities.
