been reminiscing on a spat I had about a year after Vermont Yankee was shut down. Got me blocked by a guy claiming wind and solar replaced its output - but that li'l grief was more than compensated by what I learned about he NE-ISO grid from @yes_VY .
I hit the data for an update I "storified" the encounter in 2016, so I have only a .pdf to show of it morecoldair.files.wordpress.com/2018/09/storif…
There's a lot of grey areas, not the least of which is ISO data omits distributed sources such as residential solar and other self-generation, but nuclear is down, gas up, me right..

@KHayhoe @leifsolmunde @FrantaJaro @thiesbeckers @kirstygogan @ChristiAnne67 @6point626 @EnergyJvd @Gen_Atomic @pinkheretic @Thoughtscapism @nuclearkatie sorry for the clutter folks, but I think it is important to respond to the specific mistruths about the costs of Ontario's move to a very low emissions electricity sector from the Professor - a topic she knows people would find uninteresting.

so...

@KHayhoe @leifsolmunde @FrantaJaro @thiesbeckers @kirstygogan @ChristiAnne67 @6point626 @EnergyJvd @Gen_Atomic @pinkheretic @Thoughtscapism @nuclearkatie "if you dig into the original literature" [citation "professor"] paying off the debt incurred from building nuclear..."
There was a debt at the break-up of the "Ontario Hydro" in 1998 ( see coldair.luftonline.net/2013/04/strand… ), and it is complex, but there was a fixed fee ...

The other day @elephanteating produced a thread on the economics of his woodstove.


I dug into some data for a home 148 miles northwest of Rochester.
Here's a thread with efficiency, rebound and relationships - including savings from a stove I pulled the data together for my electricity and gas bills, and just roughly estimated wood consumption.
Gas conversion: 277.8 kWh per GJ (and .038 GJ per m3),
Wood: 20 GJ/cord - a different mix of ash, maples, willow, cherry yearly (whatever came down)

The very low capacity value/credit of Alberta's industrial wind turbine potential is well known to those who follow such things.
Far fewer follow such things than pump up excitement about vRES. looks like it's a high demand day in Alberta.

Maybe the highest:

the science seems pretty confused on this, but the one thing most individuals can know without the science is the claim the CBC report ends with, and the Minister emphasizes: "more extreme weather events" aren't true where they live. not that the science is the thing that interests me, but there's a long post on Carbon Brief discussing many theories carbonbrief.org/qa-how-is-arct…

Here's 3 quotes from it related to what interests me:

I've updated my PowerBI report mapping industrial wind turbines in Ontario with production, and cost, summary pages.

(continue to be amazed by @MSPowerBI )

@powerbi
app.powerbi.com/view?r=eyJrIjo… includes new formats of old smash hits such as average monthly capacity factor, graphed by year!
PLUS... no more stale-dating!

if you wanted monthly ON electricity reporting for Canada Day - especially if you've been jonesing for May reporting from the IESO - here's my shadow reporting for June:
BI: app.powerbi.com/view?r=eyJrIjo…

Long: sites.google.com/view/cold-air-… toggle on some more months and the BI page can also provide quarterly figured:
demand up about 4%
imports up the most, followed closely by gas.
hydro down the most.

I'm going to repeat some tweets from a couple of weeks ago that didn't thread corrected - please excuse the repetition, but the points could use repeating - on CA and what I consider the WCI scam ON is now escaping from. some people are probably confused by the vast difference in information coming from @AldyenDonnelly and the statements of confidence in the WCI scheme from the polished @EcofiscalCanada hive . Maybe my view of data will make you more attentive to Aldyen...
