One of the most important measures taken in reducing impact climate change resulting from global warming is production energy clean and renewable resources. Hydroelectric power plants are leading sources. In this study, effects on hydroelectric plants, a source, have been investigated. Dogancay I II Power Plants, which built Sakarya River located basin Turkey, was selected as study area. Moreov...

We present a theoretical framework to calculate how storage affects the energy return on energy investment (EROI) ratios of wind and solar resources. Our methods identify conditions under which it is more energetically favorable to store energy than it is to simply curtail electricity production. Electrochemically based storage technologies result in much smaller EROI ratios than large-scale ge...

This paper describes a first version of a simulation model of the electrical energy system for the German federal state Bavaria in order to analyse its energy balance during the nuclear phaseout and the increase of renewable energy sources as well as energy storage capacities. According to current plans, in ten years 50 percent of the Bavarian electric power consumption should be covered by ren...

The structure of hydraulic structures power and water management systems includes gates for various purposes, which allow you to regulate distribute the flow in channels waterworks. Existing gate designs do not provide possibility generating electricity from energy stream passing through them. In order convert into electrical a new patented design is proposed allows using micro-hydroelectric pl...

The magnitude of humanity’s energy needs requires that we embrace a multitude of various energy sources and applications. For a variety of reasons, nuclear energy must be a major portion of the distribution, at least one-third. The often-cited strategic hurdle to this approach is nuclear waste disposal. Present strategies concerning disposal of nuclear waste need to be changed if the world is t...

Nowadays, it is important to consider environmental issues, as ecological problems and their severe effects are intensifying in Iran, particularly in Khuzestan province. The environmental effects of hydroelectric plants are highly regarded due to their significant impact on an extensive area. Lack of safe path for fish passing through the turbines is one of these damages. In order to deal with ...

Despite the growing scientific evidence, electricity market models used in Chile do not consider effects of climate change on hydroelectric energy production. Based a statistical analysis historical hydro-energy inflow dataset and revision literature, we suggest set technical criteria to determine an alternative representation uncertainty Chilean market. these criteria, then propose range hydro...
