by Stephen E. Aplin • February 24, 2022 • 1 Comment

Berlin Airlift, 1949: the Number One commodity flown into Berlin during that iconic early Cold War confrontation was coal. At its height, the airlift transported 5,000 tons of “commodities” per day, two thirds of which were coal. The operation began…

Solar PV, CO2 avoidance, and magic wands: attractive packaging and misleading advertising

by Stephen E. Aplin • July 23, 2020 • 6 Comments

The International Energy Agency’s Integrated Smart Grid Action Network—what does just the title of the organization say? To me, a cynical pro-nuke climate hawk, it connotes exactly the type of bureaucracy that is simultaneously useful and frustrating. Useful because it…

“E” vs “SG” in ethical investing: how sustainable is mollification-by-cherrypicking

by Stephen E. Aplin • April 11, 2020 • 7 Comments

Item A1 Current concentration of CO2 in the global atmosphere:
0.00 parts per million
In the last hour:
  • Nuclear reactors contributed 46.8 % of total electrical power generated in-province.
  • 97.3 % of Ontario-generated electricity was carbon-free.
  • Nuclear reactors contributed 48 % of Ontario's carbon-free electricity.
Table A1: Total Ontario generation, and related CO2 emissions, in hour preceding 02:05 EST on May 17 2022
FUEL MWh CO2, tons
Nuclear 6,405 0
Hydro 4,457 0
Gas 369 142
Wind 2,778 0
Biofuel 0 0
Oil & Gas 0 0
Solar 0 0
TOTAL 14,009 146
CO2 intensity per kWh (CIPK) in the last hour: 10.66 grams.
Table A2: Total Ontario generation, and related CO2 emissions, midnight to 02:05 EST on May 17 2022
FUEL MWh CO2, tons
Nuclear 19,212 0
Hydro 13,811 0
Gas 1,201 461
Wind 6,607 0
Biofuel 0 0
Oil & Gas 0 0
Solar 0 0
TOTAL 40,831 473
Average CO2 intensity per kWh (CIPK) over period: 11.59 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
146 3,669
10.66 267.79
Tons CO2
CIPK, grams
If gas had replaced nuclear last hour, Ontario power plants would have dumped enough CO2 to fill Rogers Centre 1.3 times. As it was, 146 tons were dumped, which would fill Rogers Centre 0.1 times.
