个人简介

David Layzell, PhD, FRSC is the Director of the Canadian Energy Systems Analysis Research (CESAR) Initiative at the University of Calgary (http://cesarnet.ca). From 2008 to 2012, he was the Executive Director of the Institute for Sustainable Energy, Environment and Economy (ISEEE), a cross-Faculty, graduate research and training institute at the University of Calgary. He began his academic career as a Professor of Biology (cross-appointments in the Schools of Environmental Studies and Public Policy) at Queen’s University (Kingston) where he generated over 100 peer reviewed publications, 7 patents and a technology company (Qubit Systems Inc.) before being elected as a Fellow of the Royal Society of Canada. Since 1998, he has been instrumental in building national, multi-disciplinary research networks focused on finding climate change solutions, including BIOCAP Canada, Fluxnet Canada, Green Crop Network, GHG Management Network and Carbon Management Canada. David is also Chair of the Committee on Expert Panels for the Royal Society of Canada.

研究领域

Canada’s energy systems* have fueled a very high quality of life, delivering luxuries that would be the envy of virtually all previous generations. However, these systems have brought with them some unintended consequences, including climate change. Despite the clear need to transform our energy systems to be more sustainable, there is no consensus on the precise goal, pathway or timeline. A primary goal of my research program is to develop the tools and analytical methodologies that will ‘elevate the conversation’ around energy systems choices while informing policy and investment decisions on how best to transform our energy systems for a more sustainable future. This involves: Understanding, quantifying and modeling the past and current energy systems of Canada and its provinces, including the costs, benefits and tradeoffs of energy conversion technologies that define the pathways and greenhouse gas emissions associated with energy flows. Modeling and assessing possible energy futures based on technology, policy and behavioural choices. Developing data visualization tools and technologies to assist in the understanding, validating and communicating of Canada’s past, present and possible future energy systems. Some, but not all of my research work relates to biological systems. Current research projects include: Exploring strategies for greening the Alberta electrical grid and oil sands recovery upgrading technologies; An Eco-mimicry approach for reducing greenhouse gas emissions from oil sands Tailings ponds; Integrating Canada’s agricultural for forest sectors into energy systems models. Modeling the implication of energy efficiency initiatives * Energy systems are the sum of the technologies and policies that link the energy services that people demand (light, mobility, space heating/cooling etc) to the energy sources that nature provides (sun, fossil fuels, wind, biomass, etc).
