Abstract. Since 1990 extensive funds have been spent on research in climate change. Although Earth Sciences, including climatology and hydrology, have benefited significantly, progress has proved incommensurate with the effort and funds, perhaps because these disciplines were perceived as "tools" subservient to the needs of the climate change enterprise rather than autonomous sciences. At the same time, research was misleadingly focused more on the "symptom", i.e. the emission of greenhouse gases, than on the "illness", i.e. the unsustainability of fossil fuel-based energy production. Unless energy saving and use of renewable resources become the norm, there is a real risk of severe socioeconomic crisis in the not-too-distant future. A framework for drastic paradigm change is needed, in which water plays a central role, due to its unique link to all forms of renewable energy, from production (hydro and wave power) to storage (for time-varying wind and solar sources), to biofuel production (irrigation). The extended role of water should be considered in parallel to its other uses, domestic, agricultural and industrial. Hydrology, the science of water on Earth, must move towards this new paradigm by radically rethinking its fundamentals, which are unjustifiably trapped in the 19th-century myths of deterministic theories and the zeal to eliminate uncertainty. Guidance is offered by modern statistical and quantum physics, which reveal the intrinsic character of uncertainty/entropy in nature, thus advancing towards a new understanding and modelling of physical processes, which is central to the effective use of renewable energy and water resources.

Abstract As industrialization, worldwide population growth, and improvements in the living standards in developing countries continue, demands for energy, food, and water, likewise surge. This in turn accelerates global warming, and its resultant extreme weather effects. Among the measures proposed to meet the growing energy demands, the use of renewable energy is gaining more and more attention. In particular, wave power generation is attracting a great deal of attention as an effective use of ocean energy. However, current wave generators are large and very expensive relative to their output. Furthermore, they cannot generate power efficiently with wave directivity, small amplitude waves and so on. For these reasons, widespread use is very limited. In order to solve these problems, this paper discusses the possibility of a recently developed wave power generator that uses a newly developed dielectric elastomer (DE) as a new way to harvest renewable energy. We also discuss the technical breakthrough of building a mega power generation system using DEs.

This paper is focused on new seasonal energy storage technology. World demands for energy are increasing at present, but the resources of fuel are limited. There is a prediction, that they will become rare and more expensive in subsequent years. The technology, which can contribute to increasing the efficiency of energy consumption, is thermal energy storage. The role of such energy storage systems is to accumulate heat, balancing temperature differences and achievement the most effective use of the collected energy. Thermal energy storage plays an important role in increasing the using of renewable energy.

Renewable Energy Production

This paper presents a novel driveline where the load and the energy source are operated at different voltage levels and they are galvanically insulated. The element that couples both part of the driveline is a Two Voltage Level Machine (TVLM). The machine is formed of a self-excited rotor and a stator with two sets of electrically isolated windings for adjustable speed drive applications. Both sets of these three phase windings are independently operated at different voltages. The equivalent circuit of the TVLM is deduced and phasor diagrams are presented. A complete driveline is simulated and the performance of the complete system is discussed. The driveline is applicable in flywheel energy storage systems for vehicles and power conditioning in renewable energy production.
