This paper is focused on researching the behaviour of heating companies in connection with current developments in the electricity market and flexibility in the context of market behaviour. The work assesses the increase in profitability through the creation of a technical–economic model using an objective function with profit maximization. The objective of the paper is to present the procedure and methodology for creating a model using the basic scheme of production processes integrated into the system platform. The result of the work is a comparative analysis of modelled cases of implemented operation deployment according to a defined period and modelling modes on selected time series. The description of individual outputs demonstrates the economic advantage of using combinations of modes of combined electricity and heat production, and non-combined electricity and heat production, including the use of heat-suppression mode because of overproduction of electricity.

Economic growth in the Latin America and the Caribbean region has picked up considerably during the past decade or so. This growth has been aided by widespread (earlier and more recent) investments in power generation, transmission, and distribution that increased the provision of electricity services to households, commerce, and industry. This report evaluates a number of critical issues for the power sector in the region in the coming two decades. These include the expected rates of increase in the demand for electricity, the required supply of new generating capacity, the technology and fuel mix of that generating capacity, and the carbon dioxide emissions of the sector. One of the key contributions of this study is the aggregation of individual country plans to the regional and sub regional levels, using a consistent set of data and a common methodology. The report also assesses the important roles of hydropower and natural gas, the way other clean and low-carbon resources can be expanded, the potential and benefits of greater electricity trade, and the role of energy efficiency. By considering the region as a whole, the report highlights the role that individual countries will play in shaping the region's aggregate power sector.

Because of rapid economic expansion, China, the USA, and India have become the largest energy producers and sources of CO2 emissions in the world. They burned over 45% of global fuels in 2016. Meanwhile, the developing strategies of 24 polluted states to decrease fossil energy consumption without additional economic output. This paper explores the effect of world top polluted countries’ CO2 emission, their GDP and production of electricity by potential indicators and identifies the basic factors that contribute to changes in an environment where petroleum, natural gas, coal, nuclear, biomass, and other renewable energy and hydroelectric sources are examined with GDP per capita. We estimate our data for the period from 1968 to 2017 and use the GLM model. The results show that more production of electricity is causing abnormal CO2 emissions. The Granger causality test shows that there is a unidirectional relationship between energy consumption and economic advancement. Also, there is a short-run bidirectional causality that exists among the energy indicators. We find a unilateral causality between energy consumption and economic growth. Therefore, the consumption of energy might be conductive of 24 (polluted) countries and better economic development; the consumption of energy may be failsafe and guaranteed, while we should limit the resources of countries.

As the industry develops more and more, heat is produced during fabrication processes, resulting in an excess of heat. One of the ways to solve the problem can be the conversion of excess heat into electricity using a thermoelectric generator (TEG). The authors of this paper propose a method of using thin-film TEGs for electricity generation, a procedure that has been given little attention to in the literature. In this study, thin TEGs (about 50–100 nm thick) were obtained from Bi-Ni, using magnetron sputtering technology. This type of TEG can be used not only as a device that generates electricity, but also as a protective layer for various systems, protecting them from environmental influences. In addition, such TEGs can be formed on a complex, uneven surface, with various details changing their geometric shape. As shown from XRD studies, the obtained Bi-Ni layer is polycrystalline. XRD studies help to determine whether the layer obtained is composed of pure layers of Bi and Ni metals or whether metal oxides have formed (metal oxides have a negative effect on electrical conductivity). An increase in the temperature from 80 to 120 K, respectively, increases the voltage generated by the TEG from 0.01 to 0.03 V. Meanwhile, the efficiency of such TEG element changes from 1 to 4.5% when the temperature change increases from 30 to 119 K.

The complexities of high PV penetration in the electricity grid in Slovenia based on targets proposed in national energy and climate plan were explored. Scenarios modeled an increase in installation power from 1800 MW in 2030 to 8000 MW in 2050. They were analyzed using energy modeling and life cycle assessment to assess the technical and environmental aspects of high PV grid penetration. The results showed that the increase in PV production from 2200 GWh (2030) to 11,090 GWh (2050) showed an unfavorable course of excess electricity in the system, resulting in the need for short-term and long-term storage strategies and exports of electricity. LCA analysis showed that penetration of a high share of PV results in a decrease in the impact category of global warming, which is higher in 2050 green scenarios that phase out coal and lignite electricity sources (80.5% decrease) compared to the 2020 baseline scenario. The increase in mineral resource scarcity can be observed with an increase in PV share when comparing the 2030 (50%) and 2050 (150%) BAU scenarios with the baseline scenario (2020). Factors such as environmental impacts, technical challenges, and the impact on the grid must be considered when implementing a decarbonization strategy.

We empirically examine the effects of overseas aggregate aid and energy aid inflows on renewable and non-renewable electricity production in selected BRICS countries (i.e., Brazil, India, China, and South Africa) from 1995 to 2015. Economic growth, foreign direct investment inflows, and trade openness are control variables in electricity production functions. The results from employing fully modified ordinary least square and dynamic OLS techniques indicate that economic growth, inflows of aggregate aid, energy aid, and foreign direct investment promote renewable electricity production, while trade openness reduces it. We also find that aggregate aid and energy aid inflows reduce the non-renewable electricity production, while economic growth, foreign direct investment inflows, and trade openness promote it. Moreover, our study is unique and adopts different panel estimators, ensuring the robustness of the research findings. Our findings suggest that the BRICS economies’ march towards a sustainable environment becomes possible if policymakers, in their climate mitigation policy, encourage greater investments of overseas aggregate aid and energy aid inflows toward renewable electricity production.

The rapid pace of industrialisation and economic development in recent decades is not without its environmental consequences. Electricity production, though an important determinant of economic development, remained under studied in the existing literature and only a few models on the electricity production-environmental degradation nexus are available. As a first attempt, this study examines the impact of renewable and non-renewable electricity generation and eco-innovations on CO 2 emissions in the world's top emitting countries under the umbrella of the Environmental Kuznets Curve (E.K.C.) Hypothesis. Second-generation panel data techniques, i.e., C.I.P.S. and Bai and Carrion-I-Silvestre ( 2009 ) unit root tests, Westerlund and Edgerton ( 2008 ) and Banerjee and Carrion-i-Silvestre ( 2017 ) cointegration techniques and Cross-Sectionally Augmented Distributed Lag Model for short and long run coefficient estimations have been employed in the study. It is found that renewable electricity production and eco-innovations have negative effects, whereas non-renewable electricity production has positive effect on CO 2 emission. Moreover, the estimation demonstrated the E.K.C. validation in these countries. It is recommended that fossil fuel dependency in the electricity sector should be reduced by devising policies directed towards green electricity measures. More investment in green innovations to achieve green environment and sustainable growth is also recommended by the study.

Analysis of the electric power market in a region of five EU countries (Austria, Croatia, Hungary, Italy and Slovenia) with one-sixth of the EU population reveals that in the period following the last financial crisis growth of 1% in electricity consumption led to 0.9% higher electric power prices for industry and 0.6% higher electricity prices for households. The situation on the German electricity market also holds a statistically significant influence. An increase in taxes in the German price of electricity (collected to raise funds intended for power generation from renewable sources) of 1% leads to 0.25% reduction in electricity prices for industrial use and 0.12% reduction in electricity prices for households in the analyzed group of EU Member States. From 2010 to 2015, Germany opened the subsidization of electricity generation from renewable sources from 12 to 24 billion euros per year (0.8% of GDP in 2015). This has had the impact of increasing the supply of electricity and providing only intermittent information about the actual cost of production of these goods. Between 2011 and 2015, the electric power price on the German Energy Exchange (Phelix) fell 38%.

The Middle East and North Africa (MENA) region is one of the most water-stressed parts of the world. In just over 25 years, between 1975 and 2001. Looking to the future, MENA's freshwater outlook is expected to worsen because of continued population growth and projected climate change impacts. The region's population is on the way to doubling to 700 million by 2050. Projections of climate change and variability impacts on the region's water availability are highly uncertain, but they are expected to be largely negative. To offer just one more example, rainfall and freshwater availability could decrease by up to 40 percent for some MENA countries by the end of this century. The urgent challenge is how to adapt to the future as illustrated by these numbers and how to turn the region's economy onto a sustainable path. This volume suggests new ways of thinking about the complex changes and planning needed to achieve this. New thinking will mean making better use of desert land, sun, and salt water the abundant riches of the region which can be harnessed to underpin sustainable growth. More mundane, but just as important, new thinking will also mean planning for dramatically better management of the water already available. Right now, water is very poorly managed in MENA. Inefficiencies are notorious in agriculture, where irrigation consumes up to 81 percent of extracted water. Similarly, municipal and industrial water supply systems have abnormally high losses, and most utilities are financially unsustainable. In addition, many MENA countries overexploit their fossil aquifers to meet growing water demand. None of this is sustainable while water resources decline. This volume hopes to add to the ongoing thinking and planning by presenting methodologies to address the water demand gap. It assesses the viability of desalination powered by renewable energy from economic, social, technical, and environmental viewpoints, and it reviews initiatives attempting to make renewable energy desalination a competitively viable option. The authors also highlight the change required in terms of policy, financing, and regional cooperation to make this alternative method of desalination a success. And as with any leading edge technology, the conversation here is of course about scale, cost, environmental impact, and where countries share water bodies plain good neighborly behavior.
