Just looking at the curve, it looks like the increase was between 2.5 and 3% per year over the 23 year period prior to 2022. I wouldn't call that out of control. Seems to be in line with inflation in Western nations.
An upward trend doesn't mean things are out of control or out of whack.
The only place in North America with rates even approaching those seen in Germany and Denmark and more recently the UK, which have the highest costs, is California.
So yes, if not misleading, then perhaps the issue is drawing the wrong conclusion. The graph shows me that electric prices were growing at a rate in line with inflation prior to the Russian invasion of Ukraine.
And you are absolutely free to embrace electricity costs escalating at that rate if you feel it is reasonable while we push for more consumption via electrification.
In 2022, Germany capped household electricity rates at $0.40/kWh (Euro cents), due to the impact the Ukraine situation was having on them. For me, in Canada, that's $0.59/kWh. Keep in mind, Ontario has a higher average household income than Germany does.
Now, I'm living the "green dream", having installed a heat pump, and here's my most recent electricity bill:
That's an effective all-in rate of $0.14/kWh.
This bill, if I was paying German rates, would have been $899.57
Now, as I said, maybe you'd be fine paying $900/month for electricity, but I'm certainly not. Add an EV to this scenario and things could get even more stupid! Say I used 2,200kWh, that'd be $1,300!
This is why the average German household uses 3,500kWh.... per YEAR, while a house in Quebec will use more than that in 2 months.
