Chapter
Today marine renewables represent the smallest part of the renewable energy market. Still, it is also true that marine renewable energy sources could meet electricity needs for the growing world if the marine energy utilization technologies would be perfected in the future. This chapter is divided into three main sections. In the first section, we...
Chapter
The idea behind this chapter is to provide teachers and students with material that can be used while studying renewable energy sources with special attention paid to their complementary characteristics. The questions and exercises included below refer to chapters presented in the book. In case of any questions, we provide the readers with contact...

Small hydropower plants (installed power below 10 MW) are generally considered less impacting than larger plants, and this has stimulated their rapid spread, with a developing potential that is not exhausted yet. However, since they can cause environmental impacts, especially in case of cascade installations, there is the need to operate them in a...

Small hydropower (SHP) plays an important role in the Baltic States as a reliable and efficient source of electricity from renewable sources. This study presents the historical development, current status, and possible trends for the future development of SHP in the Baltic States with insights into the legal background and development policies for...
Article
Full-text available
This paper discusses rapid flow and stage fluctuations in a large lowland river downstream from a large hydropower plant (HPP) in Lithuania. The main problem arises when the HPP is operating in peak mode. Such operation of HPP causes rapid flow and stage fluctuations, which can have a certain impact on river ecosystems. The study analyzes general a...

Full-text available
Hydropower is oldest available source for renewable energy generation in Lithuania and the world. However, because of unequal demand of electricity during the day large hydropower plants are adapted to work in hydropeaking regime, which causes rapid water level and discharge fluctuations and has impact on the environment. To assess the extent of th...

Wave power is an abundant source of energy that can be utilized to produce electricity. Therefore, assessments of wave power resources are being carried out worldwide. An overview of the recent assessments is presented in this paper, revealing the global distribution of these resources. Additionally, a study, which aims to assess the spatial distri...
Article
Full-text available
The article analyzes the effect of the Lithuanian legislation on hydropower development via the document content analysis and comparative analysis of legislation and scientific literature. The main focus of the article is on assessing the hydropower potential in line with the environmental legislation and establishing the possible development prior...
Article
The primary aim of this research was to investigate and to substantiate available methodologies based on key hydrologic, hydraulic and geometric parameters of a river to derive the theoretical hydrokinetic (HK) power. To realize this aim, hydrological and hydraulic methods were applied for the second largest river in the country. For the hydrologic...

This article discusses the environmental issues facing small hydropower plants (SHPs) operating in temperate lowland rivers of Lithuania. The research subjects are two medium head reservoir type hydro schemes considered within a context of the global fleet of SHPs in the country. This research considers general abiotic indicators (flow, level, wate...
Article
Gradually increasing interest in utilisation of wave energy through development of wave energy converters is directing more attention to areas of lower energy potential, such as the Baltic Sea, compared to the oceans. In this paper, the theoretical wave power potential in the Lithuanian coast is evaluated using available multi-year visual observati...
Article
This paper studies pumped storage plants (PSPs) operating all over the EU, in which the key statistical indicators can be found in the European Hydropower database (HYDI), administered and managed by the European Small Hydropower Association (ESHA). The main emphasis is on mixed-type PSPs, which generate electricity from natural inflow; however, pu...
Article
In this paper regression analysis was adopted to assess the wind-wave relationship between wind speeds and wave heights on the Lithuanian coast of the Baltic Sea. In the coastal observations register missing data of visual wave observations occur because of the fog, ice, evaporation or other meteorological phenomenon. There is also inconsistency in...
Article
Since discovering that signals of random waves submit to the known laws of probability, this became widely used in engineering and energetics for probability distributions analysis of wave height. From an energetic point of view, it is necessary to know the average wave height in, for example, highly wavy (1% probability), medium wavy (25% probabil...
