Long-Term Power Outage and Preparedness of the Population of a Region in the Czech Republic—A Case Study

Abstract

The power outages that have occurred in recent years around the world point to widespread problems with consequences for the lives and health of the population, but also material damage. This is a case study that focuses on the evaluation of the preparedness of the population of a selected region in the Czech Republic for a long-term power outage. This article deals with a case study that focuses on the evaluation of the preparedness of the population of the Karlovy Vary region in the field of emergency survival. Part of the study is the evaluation of the respondents’ answers, which provides an overview of the actual state of preparedness for power outages on a sample group of respondents in the Karlovy Vary region. The research method used was a survey using questionnaires. The obtained information was subsequently statistically evaluated by nonparametric correlation using Kendall’s taub. From the presented results of the survey, it is clear that the inhabitants of smaller municipalities are better prepared for a power outage and can create basic conditions for emergency survival.

“…Nevertheless, 88.2% of the participants specified having a backup power system mainly comprising solar panels and electric generators. These findings compare with the results of a previous study by Kavan et al. (2021) on the long-term outages and preparedness of a small community of Karlovy Vary in the Czech Republic.…”

These findings compare with the results of a previous study by Kavan et al (2021) on the long-term outages and preparedness of a small community of Karlovy Vary in the Czech Republic. In this study, the authors found that 90.5% of the participants stated that they had a backup power supply to cope with long-term outages and 70.7% relied on a battery-operated radio or car radio for emergency transmission of information after the failure of the backup warning network (regular session at a certain CRR 5,1 time).…”

“…Power energy systems, followed by water storage systems, were the most common local CI backup systems owned by both FSC groups. In the context of power energy backups, Kavan et al. (2021) showed that 90.5% of the participants in a small community stated that they had a backup power supply to cope with long-term outages.…”

In our study, some businesses at the progressive level stated that they had combined gas power generators with solar panel systems as energy backups and Wi-Fi cell phones with satellite Internet and telephone services.…”

Fire safety of building integrated photovoltaic systems—State of the art

“…Electrical energy can easily be converted into kinetic energy, heat energy, light energy and transmitted over long distances. Modern human society is increasingly dependent on electricity, and any major outage can lead to damage that can have an impact on the very functioning of the state (Karda and Kavan, 2023;Kavan et al, 2021). In view of this, there is an increasing use of renewable sources to produce electricity.…”
