Modern problems of the Earth’s population are increasing in the areas related to the basic concepts of survival of living beings, but also with opposite views, if parallels are made between energy and ecology. Many new technologies are searching for their way towards development and must be viewed from several points of view. In this paper, the issue is addressed through modern laser techniques in terms of obtaining energy for various purposes concerning selected roles in medicine, as well as the impact on flora, fauna and as a support to other technologies both classical and modern. Contemporary attributes of lasers and other quantum generators in terms of coherence, power and intensity densities have significantly increased, although some predictions from the time of the first quantum generator masers, like gammarasers (and X raser) are still relatively far from commercial concepts. Some of the possible contemporary implementations of quantum generators in measurements control and processing schemes, along with other possible applications of various laser types, have been estimated. The paper focuses on the characterization of today’s problems with Covid-19 virus, only from the engineering point of view. The lexical side of the issue is also included, as well as the social management needs with the application of modern technologies, including help from natural sciences.

“…Increasing energy efficiency in the SBs can only be imagined by using RES (mainly solar [30,31] and geothermal [32], sometimes wind energy [33]). The same applies to the NZEB and ZEB concepts.…”

In this investigation, a numerical and multi-criteria analysis of energy flow in the primary school in the city of Kragujevac is presented. A model of the existing school building with a district heating system was created. Alternative heating systems (the gas boiler, the pellet boiler, and the ground source heat pump) were analyzed to achieve energy savings. Different types of buildings are simulated with and without photovoltaic panels. Google SketchUp was used for building modeling, while EnergyPlus simulated buildings' energy behavior in real conditions. Results show that pellet boilers with photovoltaic panels can reduce primary energy by 89% and CO₂ emission by 87.55%. For the ground source heat pump with photovoltaic panels, the final energy saving is 77.83%, primary energy saving is 70.82%, and CO₂ reduction is 57.90%. Using numerical and multi-criteria analyses, the authors want to bring the existing public buildings closer to the zero-energy building concept and the city closer to the sustainable development concept.

“…It is a solid-state technology, does not having any moving part, emitting no harmful gases, requiring bare minimum maintenance, having almost no material depletion, being easy to install, and last but not the least producing energy silently. The solar energy applications, both photovoltaic and solar thermal include PV hybrid power systems [1], solar power in shipping [2], greenhouses and solar stills [3] and [4], solar water heating [5], solar chimney [6] and [7], solar concentrators [8], and solar hot water storage [9]. With all these advantages and wide range of applications, there is a consensus among experts and policymakers that PV systems, capable of providing power at the point of use, are on the road of widespread commercialization [10].…”

Saudi Arabia has embarked on diversification of its existing energy portfolio through rene wables, mainly solar photovoltaic and thermal, and wind power. This study presents an overview of how different areas around the world utilized building-integrated solar photovoltaic applications to recommend appropriate and suitable options for implementation in Saudi Arabia and the Middle East region. With this objective, the power utility will have three-fold benefits (i) clean and economic power arability for off-grid remotely located dwellings, (ii) cutting down the emissions of greenhouse gases, and (iii) conserving the fixed reserves of fossil fuels, which are being used mainly for power production around the world. The study shows that building-integrated applications are most common in Asian and European countries. Moreover, it is observed that monocrystalline and polycrystalline photovoltaic materials are both technologically and economically suitable for such applications.
