AbstractLife cycle analysis becomes especially important for characterizing new material forms in new energy generation technologies intended to replace or improve the current infrastructure of energy production. We propose a comparative life-cycle analysis framework for investigating the effect of introducing nanotechnology in the life cycle of new photovoltaics, which focuses on the differences between the new technologies and the ones that they may replace. The following parameters are investigated within this framework: methods of synthesizing nanoparticles, physicochemical specifications of the precursors, material utilization rates, deposition rates, energy-conversion efficiencies, and lifetime expectancy of the final product. We introduce the application of this framework in comparing nano-structured cadmium telluride and silicon films with their nano- and amorphous- structured equivalents.

This article investigates how the scale and structure of energy production influence on sustainable economic development in China. First and foremost, the relationship between energy production and economic development was discussed in theory, and a time-varying parameter state space model was established. Then an empirical study based on the annual data from 1981 to 2012 was carried out by using method of Kalman filter. The results indicate that both the increasing scale of energy production and the increasing proportion of new energy have a positive and significant influence on Chinese economic growth. Finally, the thesis draws a conclusion that, expanding the scale of energy production and optimizing the structure of energy production will significantly promote China's sustainable economic growth.

Renewable energy sources are considered a part of the future of energy production in Malaysia. The main objectives of this research are to append a new energy extraction technique that harvests energy from tides and to develop a preliminary design for a tidal energy plant at Kuching Barrage. Knowing the diameter of the turbine, the dimensions of the powerhouse are achieved in conjunction with site conditions. The centerline should be at least below the low water tide so that the tide is at all times guaranteed to be submerged. Based on this, the powerhouse has a 24.61m length, is about 100m in distance across, and its elevation is 36.39m. The construction is located downstream and the centerline habitation at -1.15 and below LSD. The calculated tidal energy plant is comprised of four bulb-type turbines installed at each barrage gate. The bulb-type turbine blades would face the sea site with 11.32m length of the draft tube. This study detailed feasibility study can be implemented.

Purpose The purpose of this study is to analyse the contribution of shifting the load of household devices from periods of renewable energy underproduction to surplus periods in order to better match energy production and demand. Design/methodology/approach An optimisation model for load shifting of household devices is developed and analysed with the help of a simulation of energy loads for the year 2030 in Germany. Findings About 1.48% of the renewable surplus energy can be used in addition which equals total savings between €15.06m and €106.71m. However, 24.47% of the surplus periods can be compensated completely and 6.38% up to a level of 94%. Research limitations/implications A 100% diffusion of smart metres and devices and a high acceptance among consumers are assumed so that the results of this study present an upper bound for the contribution of household load shifting. Practical implications Load shifting of household devices provides only a small contribution and can only be one measure among others. It is crucial to find and invest in new energy storage systems so that more renewable spill-over energy can be used. Originality/value An optimisation model for load shifting is developed. Customer behaviour and devices are considered individually and not only a fixed percental share. Beside peak load periods also periods of renewable spill-over energy are considered.

Amidst the hype of a ‘new’ energy regime in India with a singular focus on renewable energy, this paper offers a more scrupulous reading of renewables to set up a critical energy discourse. It offers a three-part analysis where it begins by questioning the entrenched idea of ‘renewables as science’ and its instrumental use of metrics and measurements to convey an unbelievable reach and significance. Highlighting the consistent invocation of a calculative ethos, it shows how an ‘empirics of targets’ relying largely on the lure and lore of a single numeric, installed capacity, is persuasively employed to gloss over the crucial distinction between the potential and reality of renewables. An associated consequence is not only its pegging to the speculative value of market-based energy production but also that it remains rooted in the assumptions of an existing system, that is, the logic of a carbon lifeworld. Renewables, as a result, display the tell-tale sign of a sustainability paradox, raising questions about their ability to master a transition to a post-fossil performativity, exasperated as they are by internal contradictions embedded within their core characteristics – efficiency/sufficiency and, more importantly, tensions between utilities and infrastructure. With loose connections to parallel initiatives such as the Smart Cities Mission, the transformative potential of renewables is undercut as it remains embedded within an abstract grid imaginary, challenging any effort to actualise it in and through the urban.

The article discusses the main problems of the using of biomass as a fuel, including the fuel use of biomass as an innovative way to generate clean energy. It is shown that according to the development of technology for the production of renewable energy sources, energy costs will decrease, and the operating time of the devices and, accordingly, their productivity will increase. Ultimately, this will allow to get a positive result, i.e. reduce harmful emissions from energy production. The methodology basis on the open statistics data and analysis of the energy balance of new energy production technologies are considered. The motivation for the using renewable energy sources in industrialized and developing countries is investigated. A review of new technologies for the using biomass as a fuel is made, which allows for efficient processing of biomass, including gasification, co-production of heat and electricity, fuel use of combustible gases generated at landfills, and production of fuel for transport in the form of methanol and biodiesel.

The renewable energy is more and more used and represents a higher and higher percentage in the world’s total energy production. The reliability of the renewable sources proves to be less predictable than the conventional ones. The need of new energy storage systems becomes imperative, and when used altogether with renewable sources, they improve the predictability of those sources, thus making possible their use in the energy system market.


The article analyzes the prospects for changes in the volume of exports of Russian coal due to the reduction of its consumption for energy production by the importing countries. The importance of Russian power generating coal for the energy supply to the world as a whole and to individual importing regions in particular is shown. It is justified that a radical and abrupt refusal to use coal as an energy source in the next few years would hardly be possible because the per capita and the total electric energy consumption has been growing all over the world. To a large extent, this is due to the increase in the number of data centers around the world, which centers do not yet have enough “green” sources of energy to ensure the uninterrupted operation thereof. Therefore, coal exports from Russia to the European countries, China and DPRK will continue to grow in the years to come; this is confirmed by the forecast models built by the authors, which models consider changes in the coal and electricity consumption by major importers. By the time the conditions are ensured for the majority of countries in the world to abandon coal as a source of electricity in order to stop air pollution, Russia will need to find opportunities for its alternative use, an example of which would be the creation and development of production of competitive products of the coal chemical industry.

In this paper, we apply an RV coefficient network to investigate the topological structure of China’s new energy stock market via daily prices of 60 component stocks of CSI (China Stock Index) New Energy Index spanning the period January 4, 2012 to March 29, 2019. Compared with the Pearson correlation coefficient, RV coefficient can better reflect the similarity between stocks from the perspective of multi-dimensional data. The empirical result indicates that (1) the scale-free characteristics of China’s new energy stock market are not significant; (2) the new energy storage is the leading sub-sector of the new energy sector and the new energy interactive equipment plays a connecting role between renewable energy production and new energy storage; (3) the most influential stock in the network is Group DMEGC Magnetics Co., Ltd., Xiamen Tungsten Co., Ltd. and GEM Co., Ltd. play an important role in the network connection. These findings are of great significance to understand the interaction between Chinese new energy stocks and the pricing mechanism of stocks. The authority should pay more attention to the new energy storage industry. Investor’s portfolios can be optimized according to the influence assessment of stocks and sub-sectors.
