Accurate and inaccurate predictions, garbage dumping, and death threats: an easy lesson about nuclear power, still not learned after 1,827 days

Item A1 Current concentration of CO2 in the global atmosphere:
415.67 parts per million
In the last hour:
  • Nuclear reactors contributed 55.6 % of total electrical power generated in-province.
  • 98.2 % of Ontario-generated electricity was carbon-free.
  • Nuclear reactors contributed 56.6 % of Ontario's carbon-free electricity.
Table A1: Total Ontario generation, and related CO2 emissions, in hour preceding 02:05 EST on Mar 03 2021
FUEL MWh CO2, tons
Nuclear 8,684 0
Hydro 3,114 0
Gas 206 80
Wind 3,987 0
Biofuel 74 74
Oil & Gas 0 0
Solar 0 0
TOTAL 16,065 159
CO2 intensity per kWh (CIPK) in the last hour: 10.18 grams.
Table A2: Total Ontario generation, and related CO2 emissions, midnight to 02:05 EST on Mar 03 2021
FUEL MWh CO2, tons
Nuclear 34,726 0
Hydro 12,685 0
Gas 878 341
Wind 14,134 0
Biofuel 296 296
Oil & Gas 0 0
Solar 0 0
TOTAL 62,719 657
Average CO2 intensity per kWh (CIPK) over period: 10.47 grams

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
159 4,935
10.18 315.91
Tons CO2
CIPK, grams
If gas had replaced nuclear last hour, Ontario power plants would have dumped enough CO2 to fill Rogers Centre 1.7 times. As it was, 159 tons were dumped, which would fill Rogers Centre 0.1 times.
