Carbon intensity and the Ontario electrical grid

With more renewable power coming on line every year — I just checked Gridwatch on a weekday morning in April and wind was supplying more electricity (11%) than natural gas (5%) — it’s more clear than ever that if the Ontario government wants to reduce carbon emissions in buildings, it will have to encourage the development of low-carbon space heating strategies that do not rely on natural gas. If the carbon intensity factors of the OBC were to change so that electricity had a lower carbon intensity than natural gas, this would represent a dramatic swing to a new structure that favours energy saving strategies that reduce natural gas consumption over those that reduce electricity consumption.
