Summary/Abstract

Cadmium telluride photovoltaic (CdTe PV) technology is growing rapidly, and already represents the largest contributor to non-silicon based photovoltaics worldwide. We assessed the extent to which CdTe PV will play a notable role in the Cd use and emission flows in the future, and whether it will be environmentally beneficial or detrimental. Our results show that while CdTe PV may account for a large percentage of future global Cd demand, its role in terms of Cd sequestration may be beneficial. We calculated that its potential contribution to yearly global Cd emissions to air and water may well be orders-of-magnitude lower than the respective current Cd emissions rates in Europe.

Implications of EMF 34 scenarios on renewable deployment and carbon abatement in Canada: Insights from a regionalized energy model / Bahn, Olivier

Bahn, Olivier	Journal Article

Summary/Abstract

This paper proposes a detailed analysis of the evolution of Canadian energy systems under some selected EMF (Energy Modeling Forum) 34 scenarios. Our analysis is based on NATEM, an energy model that follows the TIMES approach of the International Energy Agency to represent in detail the energy sector of each of the 13 Canadian provinces and territories. NATEM shows that imposing different renewable penetration constraints for electricity generation has limited impacts outside the electricity sector. In particular, greenhouse gas (GHG) emissions continue to increase over time. Conversely, the imposition of a carbon tax has broader impacts on Canadian energy systems and on GHG emissions that are almost stabilized. However, the level of the carbon tax envisions by the EMF 34 study (increasing to a maximum level of $130 per tonne by 2050) is not high enough, in a Canadian context, to trigger a decrease of GHG emissions over time as mandated by Canadian climate policies.
