Nuclear power in Alberta: prospects and challenges

by Stephen E. Aplin • January 12, 2009 • 2 Comments

Alberta is Canada’s biggest emitter of greenhouse gases (GHGs). Most emissions come from two activities: power generation, and oilsands mining and processing. Combined they emitted over 102 million tonnes of GHGs in 2004—43 percent of the provincial total, and over…

Carbon capture and recycle: a new lease on life for coal, cars

by Stephen E. Aplin • December 29, 2008 • 5 Comments

Carbon capture and sequestration (CCS) has been touted as a way to reduce emissions from coal-fired power plants. In North America, coal plants emit around 2 billion tonnes of carbon dioxide every year. Storing 2 billion tonnes of CO2 every year will be…

**Table A3** Should we replace nuclear plants with natural gas-fired ones? This table compares actual Ontario grid CO₂ emissions from the last hour with those from a grid in which gas has replaced nuclear.
Actual Ontario grid	Gas replaces nuclear
