Abstract Background Climate change and the current phase-out of fossil fuel-fired power generation are currently expanding market renewable energy more especially photovoltaic (PV) panels. Contrary to other types energies, such as wind hydroelectricity, evidence on effects PV panels biodiversity has been building up only fairly recently. have linked substantial impacts species ecosystems, first...
This paper presents a linear programming model that allocates the waters of the Euphrates and Tigris rivers to irrigation, urban consumption, and on-stream hydroelectricity production in the three riparian countries (Turkey, Syria, and Iraq), by maximizing the aggregate net benefits from water uses while accounting for water-conveyance costs. The model represents, in network form, the system ma...
The thought of socialism is an age old phenomenon in the human society. Its traces can be found writings Greek philosophers like Plato and Aristotle. Shades socialistic thoughts also discovered Santan Dharma scriptures, Islamic scriptures teachings Jesus Christ. But it was only beginning 19th century that as a political, social economic philosophy gained momentum.

First posted November 8, 2022 For additional information, contact: Director, New Mexico Water Science CenterU.S. Geological Survey6700 Edith Blvd. NEAlbuquerque, NM 87113 Construction and operation of dams provide sources clean drinking water, support large-scale irrigation, generate hydroelectricity, control floods, improve river navigation. Yet these benefits are not without cost. Dams affect...
The UHE Carlos Botelho (Lobo/Broa reservoir) was selected in 1971 for a program of ecological research, and in the last 44 years continuous sampling and studies, characterized very well this artificial ecosystem and its watershed (Tundisi and Matsumura Tundisi, 2013). The mechanisms of functioning of the reservoir were well known and the maintenance of good water quality (low conductivity – ave...
A model for other countries? Politicians and concerned citizens in other countries will observe Germany’s movements closely, as it is the first example of a high technology country turning its back on nuclear energy after using it for more than half a century. Around the world, many old and new users of nuclear reactors are sticking to their plans and policies, only adding a safety inspection h...
The interest in energy storage is currently increasing, especially from the perspectives of matching intermittent sources of renewable energy with customer demand and storing excess nuclear or thermal power during the daily cycle. Technologies to be considered for load leveling for large-scale energy systems, typically in the range of hours to days of discharge time, include pumped-storage hydr...
More than 90% of the world’s growing energy demand is satisfied by fossil fuels (BP Statistical Review ..., 2015)1. One consequence of the unrestrained use of this technology is the continuous increase of the CO2 level of the atmosphere2. There are also the challenges associated with the limitations of the corresponding resources (Hubbert, 1956; BP Statistical Review ..., 2015). Climate change ...
from Historical and Projected Nuclear Power” P Kharecha and James Hansen have made a contribution in their article about the benefits of nuclear power. However, issues of technology systems integration deserve added attention as well as addressing a few errors. Though there is some logic underpinning the notion that nuclear power can mitigate greenhouse gas emissions as a “stabilization wedge”,...
World Water Day falls on the 22nd of March each year. This year the focus will be on water and energy (http://www. unwater.org/worldwaterday). Throughout 2014, the United Nations and its member states will be prioritizing the important relationship between water and energy, particularly in addressing inequities for the ‘‘bottom billion’’ who live in slums and impoverished rural areas and who su...
