Innovation in Household Electricity Consumption: Analysis of LED Lighting and Heating Element Technology Efficiency

Abstract

Introduction. This research examines the potential for improving energy efficiency in Ukraine’s household and institutional sectors through the large-scale replacement of incandescent bulbs with LED lighting and the adoption of modern heating element technologies. It evaluates expected electricity savings and provides evidence-based recommendations for state support of these initiatives.
Problem Statement. Excessive electricity consumption in Ukraine’s household and institutional sectors persists due to outdated lighting and heating technologies, low overall energy efficiency, degradation of energy infrastructure, and the absence of a systematic state policy to promote widespread adoption of innovative energy-saving solutions.
Purpose. The purpose of this study is to analyze the effectiveness of implementing innovative technologies in Ukraine’s household electricity consumption sector — particularly LED lighting and modern heating element systems — to assess their energy-saving potential and to develop scientifically grounded recommendations for scaling state energy-efficiency programs under post-war recovery conditions.
Materials and Methods. Statistical data from the State Statistics Service of Ukraine, the International Energy Agency (IEA), and official government program reports, including the “Together We Bring Light!” initiative, have been used. Methods of analysis and synthesis, comparative analysis, techno-economic justification, and linear and logistic modeling have been applied.
Results. The replacement of 33 million incandescent bulbs with LED ones under the “Together We Bring Light!” program has yielded annual electricity savings of approximately 2.35 billion kWh, totalling more than 11.7 billion kWh over five years. A logistic model has predicted that cumulative savings will reach 22.5 billion kWh by 2030. The introduction of heating element technologies in public catering establishments has reduced electricity consumption by 11—22.5 million kWh per month, depending on the scale of adoption. The use of innovative electric heaters — particularly those based on carbon fibers — has provided energy-efficiency levels of 80—95% and has enabled reductions in electricity consumption in the catering and heating sectors by 15—30%.
Conclusions. A logistic model for forecasting electricity savings from the LED transition has been proposed, accounting for program saturation limits and user-adoption dynamics. For the first time, the need to extend the energysaving experimental program to the heating-element technology sector, supported by targeted state interventions, has been substantiated.
