The increasing demand for energy, limited resources of fossil fuel, as well as pollution of the environment and changes in the global climate have raised more interest about the renewable resources. The use of renewable resources has become a very important partof European Union policy. The aim of the paper was to analyse reed resources in Latvia, its dynamics, volume and quality to produce cle...

The paper is aimed at analyzing the potential of new information networks to solve the problems of energy management network with the use of renewable energy sources. One of the basic problems of renewable energy sources is their temporal and spatial variability. It is mainly about resources based on direct solar radiation and wind speed. New computer systems that use only classical connection-...

This paper presents the methodology developed for the SOLARGIS project a Joule project for the integration of renewable forms of energy for dispersed electricity production. The aim is to demonstrate the efficiency of GIS (Geographical Information Systems) as a toll for development of integration plans for renewable forms of energy. We present the methodologies for: renewable resources for in a...

Renewable energy integration into multi energy grids (MEG) is gradually getting popular due to the rapid depletion of fossil fuel resources and the global concern on GHG emissions through fossil fuel based energy conversion technologies. However, seasonal changes in solar and wind energy potentials make it challenging to increase the renewable energy capacity especially for urban applications w...

The world needs new, environmentally friendly, and renewable fuels to exchange for fossil fuels. The fuel must be made from cheap, abundant, and renewable resources. The research area of solar fuels aims to meet this demand. This paper discusses why we need a solar fuel, and proposes solar energy as the major renewable energy source to feed from. The scientific field concerning artificial photo...

A summary is provided of the early history of research on the flow of nonrenewable energy resources through the economy and of the flow of renewable energy resources through a natural ecosystem. The techniques are similar, and many specific applications are provided. A combined economic and ecological technique is also defined. The early history and people of the International Society Ecologica...

This paper presents a design of a hybrid energy system with renewable resources. Hybrid system can better cover the energy demands of small energy objects in comparison with the classic photovoltaic (PV) or wind energy system. Combination of different sources in cooperation with energy accumulation requires sophisticated control system. The paper describes the intended design of the hybrid syst...
