Energy Costs by Category

Via Frank Smith, the following estimates of relative costs of different energy options were published in the Globe and Mail newspaper, May 30th, 2005, credited to Grant Wing writing for the Globe and Mail. A couple of things missing here: comparison of relative capacity factors for the different options, which effectively translate into much higher per-kW capital costs, and an estimate of the scale to which each option may be available. Also, I wonder where the nuclear numbers come from - certainly not recent experience in the US or Canada. Still, a useful snapshot.
