link, going back to 2006.
I have a 210 sq. metre home and my electric bill (supplier is Enersource) averages $114 (Canadian) per month and the natural gas (supplier is Enbridge) bill is similar, $118. That is with all the various supplemental charges added in.
Of course the actual usage fluctuates so much. Power goes up in summer a lot with air conditoning, last Sept. bill worked out to $136 per month, whereas the bill for May worked out to $70 per month.
Gas is just the reverse of course, up to $194 per month in winter and down to just $32 in summer.
For sure, my gas bill is going up by about 28%, just read in the news, Enbridge just obtained a massive rate increase authorization.
I suspect that when the government enacts carbon taxes, they both will shoot up more.
