The objective of this study was to evaluate the energy requirement and environmental impacts of hydroprocessed renewable jet fuel (HRJ) production from pennycress. The system boundary included pennycress produc
In investigating the hydro-environmental impacts of such tidal energy schemes, both for regional and far field effects, a 2D numerical model has been refined to predict the hydrodynamic impacts, including wake effects and flood risk and hazard impacts, and changes in the concentration distribution ...
matrix of impactsCurrently an international topic—not only among the members of the European Union—is the use of renewable energy, such as hydro power. The subject of this paper is the environmental impact assessment of the small hydropower (SHP) plant. The paper identifies the environmental ...
The formation of a dam can also have severe impacts on habitats downstream. When the natural flow of a river is blocked so is that of the sediments and nutrients contained within the water. These sediments and nutrients are often vital for replenishing downstream ecosystems such as wetlands, flo...
These systems can have dramatically reduced as well as widely dispersed environmental impacts, rather than larger, more centralized impacts that in some cases are serious contributors to ambient air pollution, acid rain, and global climate change. Keeping in mind, the social, economical and environmen...
All of these projects are designed to have low environ- mental impacts and be sustainable and easy to maintain. Since they are mini-hydro projects, large head heights (and thus large dams) are not required [9]. Most of these 6 turbine projects favor weirs over dams which cause much less...
(N2O)] as well as ozone-depleting substances [hydrofluorocarbons (HFC), perfluorocarbons (PFC), and sulphur hexafluoride (SF6)] and all energy consumption in their annual ‘national communication’, more complete emission factors for a larger number of countries should become available over the ...
Design of new energy production models and systems, including multi-source energy production units and storage: “Managed Power Packs”. Objective: implementation of micro/nano/pico-grids based on diverse local sourcing and cybersecurity imperatives. Applications: military and sensitive industrial installat...

The goal of this study was to evaluate Mexico City Water-Energy-Food (WEF) Nexus environmental impacts using Organizational Life Cycle Assessment (OLCA), aiming to identify activities with the highest mitigation potential. Two methodological modifications to OLCA were proposed: considering WEF Nexus as...
