Energy Consumption Reduction

Desalination accounts for 1% of the total global water consumption and is an energy-intensive process, with the majority of operational expenses attributed to energy consumption. Moreover, at present, a significant portion of the power comes from traditional fossil fuel-fired power plants and the greenhouse gas emissions associated with power production along with concentrated brine discharge from the process, pose a severe threat to the environment. Due to the dramatic impact of climate change, there is a major opportunity to develop sustainable desalination processes to combat the issues of brine discharge, greenhouse gas emissions along with a reduction in energy consumption per unit of freshwater produced. Nanotechnology can play a vital role to achieve specific energy consumption reduction as nanofluids application increases the overall heat transfer coefficient enabling the production of more water for the same size desalination plant. Furthermore, concentrated brine discharge harms the marine ecosystems, and hence, this problem must also be solved to support the objective of sustainable desalination. Several studies have been carried out in the past several years in the field of nanotechnology applications for desalination, brine treatment and the role of renewable energy in desalination. This paper aims to review the major advances in this field of nanotechnology for desalination. Furthermore, a hypothesis for developing an integrated solar thermal and nanofluid sustainable desalination system, based on the cyclic economy model is proposed.

Abstract Energy efficiency measures and the enhancement of investments in renewable energy play important role in sustainable development and lead to advancement of competitiveness of national economies. The increase of renewable energy consumption and the reduction of greenhouse gas emissions are significant stages of the process to achieve the main purposes of sustainable development at global and national levels. In this paper the change in the share of renewable energy in gross final energy consumption and in the greenhouse gas emissions intensity in Hungary between 2004 and 2011 is investigated. It is demonstrated that the share of the renewable energy in gross inland energy consumption increased during the examined period. The measure and the tendency of the change in Hungary show similarity to the EU 27 average. The greenhouse gas emissions intensity of energy consumption decreased in Hungary between 2004 and 2011. According to the data, the decrease is the second largest among the European Member States.

The article is devoted to the analysis of leading practices of introduction of mechanisms of ecological progress of national economy. It is established that ecological progress is carried out by reducing the level of greenhouse gas emissions, the introduction of programs to preserve the environment and the viability of ecosystems, increase the consumption of renewable energy. As the main sources of greenhouse gas emissions in Ukraine are industry, energy and transport, it is important to implement mechanisms for ecological progress of the national economy, taking into account the successful world experience, which will allow to adapt effective mechanisms in Ukraine. The purpose of the article is to determine the effective mechanisms of ecological progress of the national economy and the formation of recommendations for its provision, taking into account the experience of leading countries. To achieve this goal, the following tasks were set: to identify indicators of environmental progress, to analyze indicators of indicators of environmental progress in Ukraine and leading countries, to explore effective measures to ensure environmental progress of leading national economies. The main methods used in the study - systematization, comparison, analysis, synthesis, generalization. To compare the ecological progress of national economies around the world, we chose the main indicators that provide an opportunity to assess the ecological progress of the national economy, namely: the index of environmental efficiency, total greenhouse gas emissions per $ 1,000. GDP, Environmental Index, Ecosystem Viability Index, Share of Renewable Energy Consumption, Existing Environmental Agreements. According to the results of the study of state policy of the leading countries of the world, the main measures of the state authorities of Ukraine and the leading countries of the world in the direction of ecological progress have been determined. According to the results of the study of measures on ecological breakthrough in the leading countries, a number of recommendations have been formed for Ukraine on the formation (formation) of components of ecological progress in the economy, taking into account the functions and responsibilities of public authorities. These recommendations should be used in the process of forming state policy to ensure sustainable development, stimulate and support the introduction of innovative environmental technologies in the economy.

The article examines the structure of modern documents of European countries in the field of climate policy, including changes in recent years. Based on the results of the analysis of the dynamics and structure of energy consumption in the European macro-region, it was revealed that against the background of the general trend of decreasing energy consumption, there is an increase in the role of renewable energy sources. When comparing the indicators of the share of renewable energy sources in energy consumption and targets for reducing greenhouse gas emissions for individual countries, significant differences were revealed for individual countries of the European macro-region.

Rising greenhouse gas emissions is an important issue of the current time. India’s massive greenhouse gas emissions is ranked third globally. The escalating energy demand in the country has opened the gateway for further increase in emissions. Recent studies suggest strong nexus between energy consumption, economic growth, and carbon emissions. This study has the objective to empirically test the aforementioned interdependencies. The co-integration test and multivariate vector error correction model (VECM) are used for the analysis and the Granger Causality test is used to establish the direction of causality. The time-series data for the period of 1971–2011 is used for the analysis. The results of the study confirm strong co-integration between variables. The causality results show that economic growth exerts a causal influence on carbon emissions, energy consumption exerts a causal influence on economic growth, and carbon emissions exert a causal influence on economic growth. Based on the results, the study suggests a policy that focuses on energy conservation and gradual replacement of fossil fuels with renewable energy sources, which would be beneficial for the environment and the society.
