<p>With the increasing penetration of renewable resources such as wind and solar, the operation and planning of power systems, especially in terms of large-scale integration, are faced with great risks due to the inherent stochasticity of natural resources. Although this uncertainty can be anticipated, the timing, magnitude, and duration of fluctuations cannot be predicted accurately. In addition, the outputs of renewable power sources are correlated in space and time, and this brings further challenges for predicting the characteristics of their future behavior. To address these issues, this paper describes an unsupervised method for renewable scenario forecasts that considers spatiotemporal correlations based on generative adversarial networks (GANs), which have been shown to generate high-quality samples. We first utilized an improved GAN to learn unknown data distributions and model the dynamic processes of renewable resources. We then generated a large number of forecasted scenarios using stochastic constrained optimization. For validation, we used power-generation data from the National Renewable Energy Laboratory wind and solar integration datasets. The experimental results validated the effectiveness of our proposed method and indicated that it has significant potential in renewable scenario analysis.</p>

This chapter focuses on non-renewable resources and their relation to conflict and migration. It explores the argument that conflict is not brought by scarcity of these resources, but rather by resource abundance and the fact that they make looting possible. Access to valuable non-renewable resources, such as energy resources, can create crises of governance. Accountability decreases and rent seeking and corruption become common behaviors. ‘Lootable’ resources increase the possibilities of high political repression and income inequality, which then cause small and large-scale ‘uprooting’. Thus, tackling the issue of bad governance is key in order to solve migration flows caused by ‘lootable’ conflicts.

An increased expansion of renewable resources and biodiesel is observed and prognosed, since fossile energy resources are about to run out. Hungary achieved outstanding sunflower years in the recent years in worldwide comparison. In the future, the feedstock of biodiesel production can also be rape besides sunflower.According to the concept of harmonious development, the balance between nature, society, economy and human environments is represented by their mutual presumptive character. Research and development need to be aligned into this system. Our aim was to examine the advantages anddisadvantages of biodiesel production in different environments, using a model to do so. In order to maintain the harmony, the existing resources have to be managed properly, taking the correlations of the system into consideration. Targeted technological developments are necessary, similarly to the improvement of energy safety and efficiency.

Large fluctuations in crude oil prices and the diminishing oil supply have left economies vulnerable to energy shortages thus placing an enormous pressure on nations around the world to seriously consider alternative renewable resources as feedstock in biofuel applications. Apart from energy security reasons, biofuels offer other advantages over their petroleum counterparts in that they contribute to the reduction in green- house gas emissions and to sustainable development. Just a few decades after discontinuing its large scale production of bioethanol for use as en- gine fuel, South Africa (SA) is again on its way to resuscitating its biofuel industry. Herein an overview is presented on South Africa’s oilseed and biofuel production, biofuels industrial strategy, industry readiness, chal- lenges in switching to biofuels and the strategies to overcome potential obstacles.

In the mid 80s Hungarian agriculture belonged to the forefront of the world in many respects, despite the fact that there was a lot to do regarding yields, production costs, production structure, and the fastness of adaptability to markets and establishing accordance between the elements of the food industry chain. The mid 1980s witnessed an energetic improvement despite the unequal pace, and then followed an era of different tensions and imbalances in Hungarian agriculture. At the time of the regime change the agricultural sector, and particularly animal production within that, suffered from the signs of crisis and it was getting into an increasingly difficult position. The vast majority of the agricultural large scale farms ceased to exist, and most of the arable land was privatised. Production fell back, its composition became more heterogeneous, sometimes with an irrational production structure and selling difficulties arouse. Profitability decreased in the field of animal production generally, and some activities even had losses. The domestic consumption fallback, which was caused by the farmers’ lack of capital, the unorganised production, and the decrease in living standards, produced an amount of unsellable goods and it made the otherwise low profitability even worse. The low level of profitability resealed in unjustified production decline and led to the fact that the number of domestic animals in Hungary decreased to a never experienced depth. Today there are positive changes in the field of animal production, which might result in the long-term growth of our livestock. This study was designed to present the major tendencies and spatial characteristics of Hungarian livestock.

In this work, a method of obtaining graphene layers from natural source specifically from rice husk was developed. A rice husk (RH) was used as a raw material, and potassium hydroxide was used as activation agent. The graphene layers were obtained after four successive stages: pre-carbonization, desilication in 1M NaOH solution, chemical activation and exfoliation of the carbonized rice husk (CRH). The obtained samples were studied using Raman spectroscopy, TEM and SEM; the Raman peaks evidenced the presence of graphene multilayers in the sample. A detailed observation of Raman spectroscopy showed that the obtained samples with ratio of 1/4 and 1/5 (RH/KOH) consisted of graphene layers with a high content of amorphous component. The yield of the product was ~ 3% by weight. This study can provide a new way to the large-scale synthesis of low-cost single and multi-layered graphene using rice husk or other renewable resources.

The thesis first analyzes the concept of mobile payment, and then it makes a distinction between remote payment and near field payment. In addition to that, it infers the development of global mobile payment, which involves the users and the market size. Secondly it probes into Chinas rapid development of mobile internet economy, whose 3G network and smart phones provides high-speed mobile Internet and visual, convenient interface for mobile payment. Thirdly, harmonization of standards of mobile payment will help create industry chain parties openness, cooperation and win-win situation and promote mobile payment intensive and large-scale development process. In the end, it probes into the win-win business model for the telecom operators and financial institutions: Telecom operators will lease SIM card space to obtain revenue and financial institutions will get more fee income.
