“…The technical characteristics of the LED streetlamps are, in fact, much superior to their 20 th century counterparts: the average power consumption is about 60 W (at a current of 350 mA); they do not require service, their service life constitutes at least 50,000 hours (12 years with 12 hours of operation), they operate at sub-zero temperatures (À50 C), and ignite instantly (Alstone & Jacobson, 2018). Moreover, their ecological impact is almost non-existent, since LED lamps do not contain any chemicals or chemical solutions that need to be disposed with great care.…”

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.

“…Larger households have a lower opportunity cost of collecting biomass [89,90], which means they are less motivated to switch to LPG. On the other hand, the ongoing costs of alternative electricity service options, such as battery-powered torches and kerosene, are more expensive than SHS [91], so the larger the household the greater the potential financial saving from using a SHS. The other key difference was location.…”

Globally, rates of electrification and clean cooking are low, particularly in Sub-Saharan Africa. Off-grid energy solutions have a vital role to play in accelerating clean energy access to address Sustainable Development Goal 7. For organisations aiming to provide both electricity and cooking services, there is a need for holistic studies on adoption determinants to aid market expansion. This paper presents a comprehensive literature review of the adoption determinants and barriers for liquefied petroleum gas (LPG), solar home systems (SHS) and electric cooking (e-cooking) in Sub-Saharan Africa. A total of 40 adoption determinants were identified across the 71 publications examined. Of these, 30 determinants were shared by at least two of the technologies, whilst six were specifically linked to LPG and four to SHS. Key determinants that cut across technologies included reliability of alternative technologies (such as grid supply), reliable energy supply through the technology in question, affordability, household size and location (urban/rural). The findings show that there is an overlap in the demographics that use these technologies, as urban households often use SHS as a backup to the electricity grid and their cooking needs can feasibly be met by LPG or e-cooking devices. There is a clear opportunity for e-cooking devices to be sold as appliances for SHS. E-cooking devices such as electric pressure cookers can be complementary to LPG due to their suitability for cooking different foods. Pay-as-you-go models, which have a proven track record with improving access to SHS and are beginning to also be applied to LPG, have the potential to provide a strong foundation for scaling up of LPG and e-cooking services.

“…More than 1.2 million people in the present world are still having zero access to electricity leaving them with no viable alternative than using fossil fuel-based lighting sources which could jeopardize the earth's climate. 1 Thus, most of the nations are in the process of making plans and policies to boost up the development of a sustainable and environmentally benign lighting fixture. In this process, solid state lighting is one of the cutting-edge technologies which could offer the same lighting without causing harm to the environment.…”
