Pakistan's local currency has been devalued during different exchange regimes, which may substantially affect energy consumption and CO2 emissions. Therefore, this study investigates the effects of exchange rate depreciation on Pakistan's CO2 emissions and energy consumption from 1990–2018. We apply the nonlinear autoregressive distributed lag (ARDL) cointegration approach for the empirical analysis and found that exchange rate depreciation increases CO2 emissions and energy consumption in both the short and long runs. These results suggest that currency devaluation has an expansionary effect which enhances economic growth at the cost of high energy consumption and CO2 emissions. Therefore, the government needs regulations along with an exchange rate policy to control CO2 emissions. Moreover, the government should search for alternate energy resources such as renewable energy resources that meet the country's energy needs and mitigate CO2 emissions.

Abstract In our days, energy issues belong to the most important problems facing the Earth and the solution may be expected partly from decreasing the amount of the energy used and partly from the increased utilisation of renewable energy resources. A substantial part of energy consumption is related to buildings and includes, inter alia, the use for cooling/heating, lighting and cooking purposes. In the view of the above, special attention has been paid to minimising the energy consumption of buildings since the late 1980s. Within the framework of that, the passive house was created, a building in which the thermal comfort can be achieved solely by postheating or postcooling of the fresh air mass without a need for recirculated air. The aim of the paper is to study the changes in the construction of passive houses over time. In addition, the differences between the geographical locations and the observable peculiarities with regard to the individual building types are also presented.

Abstract To take full advantage of the flexibility of access and disconnection from smart grid, organizing distributed renewable energy resources in form of microgrid becomes one solution of energy replenishment in smart grid. A large amount of accurate and comprehensive information data are needed to be monitored by a variety of different types of sensors to guarantee the effective operation of this kind of microgrid. Energy consumption of microgrid monitoring WSN consequently becomes an issue. This paper presents a novel lifetime prolongation algorithm based on cooperative coverage of different types of sensors. Firstly, according to the requirements of monitoring business, the construction of cooperative coverage sets and connected monitoring WSN are discussed. Secondly, energy consumption is analyzed based on cooperative coverage. Finally, the cooperative coverage based lifetime prolongation algorithm (CC-LP) is proposed. Both the energy consumption balancing inside the cooperative coverage set and the switching scheduling between cooperative coverage sets are discussed. Then we draw into an improved ant colony optimization algorithm to calculate the switching scheduling. Simulation results show that this novel algorithm can effectively prolong the lifetime of monitoring WSN, especially in the monitoring area with a large deployed density of different types of sensors.

Research background: Energy policy is closely linked to economic development. Therefore, its optimization is an important issue especially in the contemporary European environmental conditions.  EU regulations enforce a reduction of carbon dioxide emissions and the abandonment of non-renewable energy resources. Instead, they promote renewable energy sources. In this way, new legal and environmental circumstances are becoming the main reason for the transformation of energy balances, which is a real economic and technological challenge. This transformation requires a strategic and effective approach, especially in those countries which until now have used mainly hard coal in the energy sector. Purpose of the article: According to above justification, the main purpose of the article is to identify the strategies for the transformation of energy balances that were implemented in the years 1990–2017 by chosen European countries and Turkey. Methods: The study period covers the years 1990–2017, and the subject of the research at first applies to all European countries, and then to 7 countries selected due to their high share of bituminous coal in energy balance in the first year of the analysis, treated as the initial point of transformation (1990). As a result of this selection, 6 EU members and Turkey with the largest share of coal in energy production in the year 1990 are examined. Particularly, an analysis of the trends in their energy balances in the years 1990–2017 is conducted. The research uses data on non-renewable energy consumption and renewable energy resources and the total energy consumption. The research methodology includes: analysis of the structure and dynamics, evaluation of trends and comparative analysis and presentation of development strategies. At the end of the article, a comparative analysis is carried out, the economic consequences of identified changes are assessed, and recommendations are formulated aimed at optimizing the structure of the energy balance in the future. Findings & Value added: Generally, there are four theoretical and empirical patterns of transformation strategies of energy balances with dominant coal consumption: 1) using other non-renewable energy resources; 2) replacing non-renewable energy resources with renewable ones; 3) using nuclear energy instead of coal; 4) increasing coal consumption as available and efficient energy resource. It was found that the examined countries implement mainly the strategy in which the decreasing share of coal is made up for by an increasing share of gas. Additionally, we can observe an increase in the share of nuclear energy in France, the Czech Republic and the United Kingdom. In Spain and Germany, despite the use of nuclear power plants for the production of energy, the share of nuclear energy in the energy balances has systematically decreased in time. In all analyzed countries, we can also observe an increasing share of renewable sources in energy balances, however, this growth is very slow.

AbstractThe study applied the autoregressive distributed lag (ARDL) technique in investigating the effect of capital inflows and exchange rate on agricultural output in Nigeria between the periods 1981 and 2016. The technique was selected because the variables are integrated at both 1(1) and 1(0) and the sample size is considerably small. Variables used in the study are agricultural output (AO), private capital inflow (PRCI), public capital inflow (PUBCI), investment (INV), labor (L) and real effective exchange rate. Findings from the empirical research revealed that the variables are cointegrated. The research outcome also indicates that in the short run and long run, private capital inflow and public capital inflow positively affect the country agricultural output. The study also revealed that exchange rate depreciation would cause agricultural output to decline in the short and long run. Based on the research findings, it is recommended that the government should create an enabling and conducive environment to attract more inflows of foreign capital into the country to boost the agricultural output. Also, monetary authority should ensure the stability of the country’s exchange rate (Naira) since exchange rate depreciation affects agricultural output negatively. Furthermore, there is the need for the harmonization of foreign capital inflow policy and monetary policy by the government, taking into consideration the optimal level of capital inflow that will not have a detrimental effect on exchange rate so as to ensure sustainable growth in agricultural output.

The first stage of transition in the Czech Republic is over. This country has a market economy and it is working. The second stage of transformation is the rapid catch-up with Western Europe. The main steps may be following: The first involves macro-economic policies, especially exchange rate policy. Exchange rate policy should be managed consistently to protect the competitiveness of export industries. The second item is tax policy. The government spending should be compatible with the level of development and the level of income - it should be in the order of 25 - 30 %. Pension reform. Flexible labor markets. Market access. Infrastructure. Transport, communications.

Energy is often the most significant factor in the affordability and sustainability of treating various different source waters with reverse osmosis membrane facilities. More than 33% of the cost to produce water using reverse osmosis (RO) technology is attributed to electrical demands. The largest energy-consuming component of the overall treatment are the high pressure pumps required to feed water to the process. Because of the high energy burden and production of greenhouse gas (GHG) emissions, renewable energy is being increasingly considered for desalination projects. The selection of the appropriate renewable energy resource depends on several factors, including plant size, feed water salinity, remoteness, availability of grid electricity, technical infrastructure, and the type and potential of the local renewable energy resource. The cost of desalination with renewable energy resources, as opposed to desalination with conventional energy sources, can be an important alternative to consider when reduced environmental impact and lower gas emissions are required. Considering the proposed climate protection targets that have been set and the strong environmental drivers for lowered energy usage, future water desalination and advanced water treatment systems around the world could be increasingly powered by renewable energy resources. In addition to renewables, energy optimization/minimization is deemed critical to desalting resource management. Methods employed include enhanced system design, high efficiency pumping, energy recovery devices and use of advanced membrane materials.

Despite some decisions approved by the Government of Ukraine to address the problems of efficient and environmentally sound solid waste management, in particular those that accumulate as a result of economic activity of the agro-industrial complex of the state, their practical implementation of measures declared by the Government is currently low. levels. Among a number of deterrents, the main ones include: lack of centralized recycling facilities and economically accessible for small facilities technical and technological base of waste processing, ineffective environmental control and the necessary management practices. However, vegetable waste is not always used, although it is a valuable raw material that can be used as a raw material for the production of fuel pellets, which will significantly reduce the energy dependence of the enterprise. An integral part of the technological cycle of processing plant residues into fuel briquettes is the preparation of biomass for briquetting in order to ensure the required particle size. Given the strategic importance of the formation of material and technical base to ensure highly efficient processing of agricultural waste of plant origin, as well as high energy consumption, which marks the traditional preparation of biomass for briquetting, there is a need for research to solve the problem of energy efficient grinding of structurally heterogeneous materials. high moisture content, which determines the relevance of the article. Thus, in order to achieve high efficiency of the process of grinding waste of plant origin, promising ways to reduce the energy consumption of this process based on the energy balance of the vibratory crusher rotor type and analysis of relationships between elements of the structural block diagram of the energy balance of the technological system "Vibration-rotor crusher - the processed environment ".

The present reality of the Nigerian economy is the fact that inflation has remained unabated in spite of all exchange rate measures that have been adopted by the monetary authority. This calls for investigation into the extent to which exchange rate impact on inflation in Nigeria. The research paper examined the impact of exchange rate depreciation on inflation in Nigeria for the period 1981–2017, using Auto Regressive Distributed Lag (ARDL) Bounds Test Cointegration Procedure. The research shows that inflation rate in Nigeria is highly susceptible to lagged inflation rate, exchange rate, lagged exchange rate, lagged broad money, and lagged gross domestic product at 5% level of significance. A long run relationship was also found to exist between inflation rate, gross domestic product and general government expenditure, indicating that the model has a self-adjusting mechanism for correcting any deviation of the variables from equilibrium. Therefore, this study concludes that exchange rate is an important tool to manage inflation in the country; thus, this paper recommends that policies that have direct influence on inflation as well as exchange rate policies that would checkmate inflation movement in the country, should be used by the Central Bank of Nigeria. Also, monetary growth and import management policies should be put in place to encourage domestic production of export commodities, which are currently short-supplied. In addition, policy makers should not rely on this instrument totally to control inflation, but should use it as a complement to other macro-economic policies.

Exchange rate policies are germane to industrial subsector development and the country at large. In this regard; the study examines the asymmetric pass through of official exchange rate policy on Nigerian industrial Subsector from 1970Q1 to 2019Q4. Non-linear ARDL method of estimation was adopted to ascertain the long run and short run asymmetric relation between official exchange rate and industrial output subsector. The results confirmed the presence of both long run and short run asymmetries between manufacturing output and official exchange rate. In the long run, increase in official exchange rate (appreciation) portends a corresponding increase in manufacturing output, while decrease in official exchange rate (depreciation) is negatively related to manufacturing output. On the other hand, the short run dynamics revealed that positive changes in official exchange rate choked off industrial output though statistically insignificance while negative change (depreciation) crowded in industrial output in Nigeria in the period under review against a priori expectation. The result also indicated that the crowding out impact of official exchange rate depreciation is more enduring (long lasting) compared to the positive variations. The presence of asymmetry is novel and instructive for policy pundits, executors, theorists, monetary authorities and allied agents to take decisive steps in order to stem the debilitating effects of exchange rate misalignment to encourage domestic investors, attract foreign investors and thus, stimulate the industrial subsector.
