Water-energy nexus approach to compare performance of evaporative and vapor-compression cooling systems

Dolaana Khovalyg, Amirreza Heidari, Nasim Soori

Evaporative cooling systems consume high water, but low electricity for their operation. On the other hand, vapor compression systems consume no water, but high electricity. Water and energy systems are interconnected at different levels. Therefore, water ...

The emission benefits of European integration

Vincent Moreau, Luis Costa

Simulating the implications of Brexit on the UK's emissions embodied in trade with a multi-region input-output table exposes the benefits of European integration. Under 2014 trade volumes, technologies and energy mixes, a hard Brexit-reverting to a trade p ...

Hydraulic performance evaluation of a micro-turbine with counter rotating runners by experimental investigation and numerical simulation

François Avellan, Elena Vagnoni, Cécile Münch-Alligné, Loïc Andolfatto

The development of energy recovery systems on existing water utility networks is a new challenge for increasing the sustainability of electricity generation mix. The concept of the new micro-turbine with counter rotating runners braces this goal by allowin ...

Four decades of hindsight into a complex hydropower system

Anton Schleiss, Pedro Filipe De Almeida Manso, Bettina Schaefli, José Pedro Gamito de Saldanha Calado Matos

Hydropower systems often operate in contextual conditions quite different from those for which they have been planned for. Often, the pace at which the changes occur does not invite operators to analyse their long-term effects and quantify the resilience o ...

Exploring the potential of e-mobility to improve resource efficiency through scenario-based life cycle analysis

The transport sector is the second largest emitter of GHG emissions in the EU and about two thirds of the emissions are generated from road transport. More importantly, while emissions from other sectors have shown a consistent decreasing trend, GHG emissi ...

Employment impacts of decarbonizing the economy: An alternative method between I-O analysis and CGE modelling

Marc Vielle, Boris Thurm

What are the impacts of an energy transition and green policies on employments? To answer this question, two approaches are widely used in the literature: Input-Output (IO) analysis and Computable General Equilibrium (CGE) models. While I-O analysis is a s ...

Impact of combined wind and solar energy on the Swiss electricity system

Jérôme François Sylvain Dujardin

As part of its 2050 energy strategy, Switzerland plans to phase out nuclear power production and replace most or all of its significant share of national electricity production (40%) by renewables, in particular by photovoltaics (PV) and wind energy. We in ...

Analysis of future hydropower development and operational scenarios on the zambezi river basin

Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos, Théodora Cohen Liechti

The Zambezi River basin is the fourth largest in Africa. Covering an area of about 1 400 000 km2 that is shared among 8 countries, it is the home of over 30 million people. There are ample opportunities for development in the region, including on the hydro ...
