The Sustainability Of Decarbonizing The Grid: A Multi-Model Decision Analysis Applied To Mexico, Rodrigo Mercado Fernandez, Erin Baker Jan 2022

The Sustainability Of Decarbonizing The Grid: A Multi-Model Decision Analysis Applied To Mexico, Rodrigo Mercado Fernandez, Erin Baker

Publications

Mexico recognizes its vulnerability to the effects of climate change, including sea level rise, increasing average temperatures, more frequent extreme weather events and changes to the hydrological cycle. Because of these concerns Mexico has a vested interest in developing sustainable strategies for mitigating climate change as it develops its electricity grid. In this study, we use a set of sustainability criteria to evaluate a number of model-derived pathways for the electricity grid aimed at meeting Mexico's climate goals. We use a multi-step approach, combining pathways from multiple large scale global models with a detailed electricity model to leverage geographic information …


Modeling The Economic And Environmental Performance Of Offshore Wind Energy, Alexana Cranmer Jul 2017

Modeling The Economic And Environmental Performance Of Offshore Wind Energy, Alexana Cranmer

Doctoral Dissertations

Offshore wind is a growing source of energy globally. Like any energy technology, it has impacts on the environment. In the case of renewable energy, we need a way to consider the environmental benefits as well as the environmental costs. This dissertation develops a set of models to examine the economic and environmental costs and benefits and the trade-offs between them. We ask how much offshore wind energy should be sited, and where should that offshore wind energy be located? The first model estimates the economic impact of wake interactions between wind farms. Wind farm sites are chosen through a …
