Domestic Hot Water (#DHW) periodic #pasteurisation of storage to prevent #Legionnaires' disease is hard to do with a heat pump (getting up to ~60C), so I do something a bit differerent:
https://www.earth.org.uk/eddi-diverter-dataset.html
When there is sufficient sunshine the system is set up to automagically do it a bit less than weekly by direct diversion from PV; in winter once or twice a month from the #grid when #carbonIntensity is low...
The Bank of Korea proposes a Korea-style climate benchmark index, which, in pilot tests, outperformed KOSPI returns while significantly reducing carbon intensity, aiming to boost green finance and global competitiveness despite current data and investment limitations.

This makes interesting reading if you're considering adding a battery to your #SolarPV system. If we assume 1 kWh of #PV-generated electricity has a #CarbonIntensity of 35 gCO2, adding a battery increases this by 84 gCO2/kWh (less if only one inverter is needed).
https://doi.org/10.1016/j.jclepro.2022.132899
This brings the total to 120 gCO2/kWh, which is comparable to the current annual average for the NZ electricity network:

(Although, as I type, it's 33 gCO2/kWh, thanks to 96% renewables!)
@jfparis @anxiumer18539 That is very cool, certainly a step up from just eyeballing it, as I do. Unfortunately I don't think there is a #CarbonIntensity forecast available for NZ... yet. I will be suggesting it!
@lightweight Yeah, just a simple #HomeAssistant setup running on a #RaspPi B+. I log the #SolarHotWater and room temps, monitor energy usage using an old Cent-a-meter and scrape #CarbonIntensity data. That's about all my wee Pi can manage!

@lightweight That's what I'm feeding into my #EV at the moment! It must be why the #CarbonIntensity is so low 😉 Can you heat your hot water, effectively using your HWC as a "battery"?
Everyone checks the #CarbonIntensity of their electricity before they charge their #EV, right?

2 concepts:
“Reducing the #carbonIntensity of the economy. In practical terms, this is what we're doing with renewables. Because there's a need for back-up, because they're not completely decarbonized either, because they power an economy that in its very materiality (steel, cement, plastic) will depend on carbon for a long time to come: an electric car, for example, is obviously not decarbonized, even if it reduces the carbon intensity of transport. This is obvious. Why do we have to make it clear? Because it forces us to leave the question of the size of the #economy on the table.
“#Degrowth, the dismantling of certain hopes, projects, technical devices. There are things that we're going to have to reduce or even abandon, and organize that. And once we've said that, the question of distribution reappears. If we can't imagine a world where everything will grow without environmental problems, the question of inequality will come back with a vengeance.”
I try to be an optimist and also am guilty of posting more positive than negative.
For all of my praise of our Midwest grid’s renewable commitments, it all falls apart on yucky hot days. We must do better 😭
86% fossil fuel, and it’s only 9:30 AM and 85°F.

Hi
I am a bot that toot about #Weather observations, low flying #Airplane, tide and #CarbonIntensity of electricity for #Mortlake #EastSheen near #RichmondPark #RichmondUponThames in #SW14 London
I am powered by #HomeAssistant
I am operated by @jfparis
This is about the lowest uk #carbonintensity figure I’ve seen in my occasional checks…

More of a personal project than DigitalPebble stuff, but I am
making good progress with my #carbonintensity API in #rustlang
https://github.com/jnioche/carbonintensity-api
Learning a new programming language is quite a challenge but am really enjoying #Rust
Hoping to publish an initial version of the library soon and integrate it in other projects like carbond / octopower / glowmarkt
@nick have a look at these - you could plot your gas consumption in your dashboard alongside the temperature

Hello #GivEnergy peeps. I’m following the hashtag. We’ve got max 72% of 3.9 kW solar and 9.5 kWh battery. The EV is a lease though #OctopusEV so we’ve got the Ohme charger and 10p/kWh overnight rate… all since December 22. At the moment paid off by 2033 so about 7.2% p.a. return. More importantly though, very low #carbonintensity
The momentum for #decarbonisation has been building:
"The new data from Rhodium suggests that, despite the shocks of the pandemic and the war in Ukraine, the U.S. is on a long-term path toward a cleaner grid."
#emissions, #CarbonIntensity

Got a #zigbee extension lead for Christmas so now I can automatically charge up my #ebike and all other associated shiz when #CarbonIntensity is low, via the ✨magic of #HomeAssistant automation✨ Thanks @GlitchEngine 💜
I love #WindPower. The #CarbonIntensity right now for the #SouthwestPowerPool is EXCELLENT. This isn’t abnormal at night ‘round these parts, thankfully.
