Is humidity control just for warm-humid weather? Or can you grow mold in winter?

A little thread for the part of #energytwitter that hasn't seen the bigger picture of #buildingscience.

1/
First, if you think you're immune to moisture & mold problems because your climate is dry in summer, let me invite you to take a look inside your fridge. What's inside that container in the back that you've forgotten for a couple of months.

Extreme example: Family in Kansas had a poorly insulated building enclosure. They kept the inside relative humidity at 50% while outdoor temperature was -5 °F.

Yes, that's ice on the walls & ceiling inside the house. Here are the details:

Feb 2022 update - #Nordic new personnel car registrations #BEV #PHEV #ICE per country 🇳🇴🇸🇪🇫🇮🇳🇱.

BREAKING: 🇳🇴&🇸🇪 12-month BEV% accelerating! Monthly % well above 12-month moving average. 🇫🇮&🇳🇱 slowing down for Jan-Feb 2022, below the trend🙁 1/x
For the 1st time I need to make different linear predictions per country for the middle part of the #BEV s-curve.

According to this 🇳🇴 will reach 100% by Dec 2023! 🇸🇪 will reach 50% early 2024, 🇫🇮 mid 2025 and 🇳🇱 by the end 2025. 2/x
🇳🇴 new personnel car market growth has stopped, but it looks very different to all other markets! This has helped 🇳🇴 car fleet #electrification, >16% is already #BEV. elbil.no/om-elbil/elbil…

#ICE decline is a clear trend for both #diesel & #petrol, in that order. 3/x

ZBF release finally draws closer (zero2050usa.com). We have been working to get the data/report out & understandable. Here is a short thread with some interesting observations that we made. First, here is a cheat sheet for our scenarios (a wide spread of possibilities)
First, we find that scenarios have huge amounts of #wind & #solar. We also find that deployment rates for these (& #storage) must dramatically increase to reach our goals (with and without novel generation).
This becomes increasingly important for limited technology cases & huge for #storage in terms of energy capacity.

1/ On the "energy transition" and geoeconomics:
My experience, including e.g. lobbying for #electrification of #transport before it was cool, is that govts prefer the path of least resistance, which helps the incumbent #oil and #gas industry.
2/ So what you get is a compromise of #green policy goals (lower CO2, but not too fast, plus nuclear exit), slow-exiting of #oil and increase in #gas (good for incumbent industry), promotion of #hydrogen (helps gas industry survive), and of course #Russia.
3/ Liberal economic principles, and foreign policy idealism, are brought in just in time to prevent heavy geoeconomic measures to cut dependence on Russia. And so, Europe will do a slow energy transition with Russia guaranteed major benefits for the next few decades.

Our take on the @EU_Commission’s second part of the #Fitfor55 package aimed at re-designing the EU’s internal #gasmarket rules and governing a future European #hydrogen pipeline network. 1/12
1️⃣ gas market: The proposed revisions to the internal gas market rules do not address that Europe’s #climatetargets imply a rapidly shrinking market for #fossilgas use already this decade. 2/12
The need to scale down #fossilgas and replacement by #electrification and only partially by non-fossil gases must become the underlying narrative of the gas market rules. Here is why! 3/12

Getting the whole world to #netzero #GHGs rapidly is going to be incredibly difficult. But given how strong and organized the #climateopposition is, we must distinguish #thesignalfromthenoise on which pathways are the most likely to succeed. A 🧵 on how I think about this 1/14
2/ First, we cannot rely on social and lifestyle change governed by new paradigms like degrowth to deliver in time for this #climatedecade. But if the movement delivers small reductions in energy or meat consumption, we need it jackrabbithomes.org/can-we-save-th…
3/ #Technologyandpolicy (and politics) need to do the heavy lifting. Can they deliver? Yes, but to effectively channel our efforts and fight off the opposition, we need to distinguish between main courses, side dishes and poison pills (frequently buried in the side dishes)

We have published an English summary of our hydrogen report: umweltrat.de/SharedDocs/Dow…
 
Key messages:
Hydrogen is necessary for #climateneutrality, but needs to be used in an efficient manner. Only #greenhydrogen produced from #renewable power can be produced sustainably.
Blue hydrogen is currently discussed as a bridging technology. In our opinion, it is not sustainable due to residual GHG emissions, insufficient short-term #CCS capacity and the risk of #fossil infrastructure lock-in. Therefore, it should not receive public subsidies.
Stringent certification is necessary to minimize the environmental footprint and social issues of hydrogen. This is both true for imports and European production.
 
An additionality criterion for renewables can ensure that green hydrogen does indeed reduce carbon emissions.

Long🧵on the provisions of #BuildBackBetter on all things #electricity & #grid. The act starts w/ ~3bn in loans for electric co-ops @NRECANews, incl. projects w/ #batteries. Co-ops have been very involved in @ENERGY-funded R&D & are now enabled to bring results to practice! 1/
It is funny that in my postdoc work @CMU_ECE & @NRECANews w/ @eeregov funding, we actually studied the added value of #battery to #photovoltaics for residential customers' energy cost savings: energy.gov/eere/solar/pro… & [1],[3], [4] here panay1ot1s.com/publications-s… 2/
Another ~10bn to co-ops for loans until 2031 to improve #resilience & #reliability w/ investments in #renewables & #transmission . Co-ops 'own' transmission lines & this money can motivate adjacent upgrades. Also critical that #renewables & #transmission appear together here! 3/

Few take-aways 1/ Image
Good that #SaudiArabia & #UAE have pledged #NetZero but #GCC total domestic emissions are only 2.4% of world’s. The #EU needs to focus on the emissions they export, mostly to #China, I argue how: bit.ly/2XOK8bG 2/
As shown by the #SaudiGreenInitiative & #MiddleEastGreenInitiative + #UAE willingness to host #COP 28, the #GCC leaders now see a political value in embracing the #climate agenda. This paper described what each #GCC country is actually *doing* about it: bit.ly/2XOK8bG 3/

We need incentives for low-cost, MINIMUM efficiency heat pumps as a cornerstone of US #decarbonization strategy.  And we need them NOW.  Why?  A thread... /1
The best time to install a HP is when the AC fails. Over the next 20 yrs, most of the existing single-purpose central ACs in the US will fail, starting w the oldest, least-efficient w the most harmful refrigerants. All should be replaced with a dual-purpose (cool&heat) HP. /2
As we detail in our 3H paper, dual-purpose HPs are exactly the same as single-purpose ACs in the summer months, and deliver many additional benefits in winter (energy bill savings, greater flexibility & resilience, etc.). clasp.ngo/research/all/3… /3

(1/5) Thread: Some good utility-side #electrification insights from @ICF: icf.com/insights/energ…
(2/5) In an @ICF study of 2050 #decarbonization pathways for NYC buildings, #energyefficiency and #electrification are both substantial contributors… in all scenarios providing ~60% of the total decarbonization potential. The point: We must do *both* to be successful!
(3/5) In an @ICF study of 2050 #decarbonization pathways for DC, the 2050 annual peak demand shifts from summer to winter, increasing ~50% in the electrification case relative to BAU, while total annual kWh sales also increase by 22%.

#Climate needs #electrification AND #hydrogen.
Both compete for #renewableelectricity, policy and infrastructure support. Policy makers have to take decisions, secure expectations, avoid further fossil lock-in
Our paper offers guidance.

#efuels(right) replace fossils without the end-use transformation required by (direct) #electrification(left)
This promises to make combustion technologies and fossil infrastructure part of the climate solution;
yet, shifting the burden to the supply side has limitations…
3/8
#Efuels require 2 – 14 times more (renewable) electricity than a direct #electrification (e.g. electric cars are five times more efficient)
Remember, (growing) renewable power capacity is far from fully meeting only today’s electricity demand.

🚀 Launch day! New study from @HarvardCCHANGE: burning gas, biomass, & wood now has MORE negative health impacts than coal in many states. 1st study to inventory health impacts of each fuel burned at stationary sources over last 10 years. To protect health, we must #ProtectOurAir Image
Air pollution costs us. It is no longer mostly from coal. In 2017, air pollution from buildings, power plants, industrial boilers, and other industries were responsible for an estimated 48-64,000 early deaths. Between 70 -77% are from burning gas, wood, biomass.😲 Image
Air pollution from buildings, power plants, industrial boilers, and other industries were responsible for an estimated $615 billion in health impacts in 2017. That’s a lot of 🤑, consider that only 6 companies have ever been valued at over $600B.

This week we published our @ETC_energy report on clean #hydrogen🟢in an electrified economy⚡️. I will be posting some key insights here in the next 2 wks.

Today, I start w/ our vision for the role of #CleanHydrogen for #NetZero2050.
bit.ly/3sZDOrg #EnergyTwitter
#CleanHydrogen in a #netzero world will play a critical role in sectors where direct electrification will likely remain impossible or uneconomic for many decades.

Electrify wherever possible. Use hydrogen wherever not possible. Image
We have high confidence in the role of #CleanHydrogen for already existing uses - like ammonia for fertiliser, or methanol.

And think that hydrogen use in steel🔩, shipping🚢, aviation✈️ and power storage🔋 is highly likely to develop. Image

Did you see yesterday's announcement about the EasyBat app, built by @bebat_BE and running on the #EnergyWeb tech stack?

Learn more about EasyBat and how it works here: energyweb.org/technology/app…

Also, check out this brief thread. 👇 Image
EasyBat is a #blockchain-based solution for identifying and tracking batteries throughout their lifecycle, from production, to ownership and operation, to second-life uses, recycling, and/or end-of-life disposal.
#Electrification & #energystorage are key components of the global #EnergyTransition, so this is a pretty big deal... not just for consumer batteries, but also for stationary batteries that are part of residential & commercial #solar PV systems, not to mention #ElectricVehicles.

#Cascadia's climate activists have had global impact, yet emissions keep rising here in #Washington #Oregon & #BC.

2021 opens with renewed hope for a real transition, as documented in Part 3 of @INVW's year-long Getting to Zero #decarbonization project. invw.org/2021/01/25/aft…
#BritishColumbia set the pace when #Cascadia's govts set initial climate targets >10yrs ago. In 2021 #Washington and @JayInslee step way out with a 95%/net-zero target for 2050, tough interim goals, and a detailed strategy to get there.

#Washington's strategy is backed by sophisticated modeling from Seattle-based CETI and SF-based EER.

So we start with the 1st line & hit the buffers as we hit the “reallocate funds fallacy”. This has been explained so many times. Cancelling #HS2 means no money for anything else. Funds raised for #HS2 can ONLY be spent on HS2 & these funds are borrowed against future use.
If there’s no HS2, there’s no funding for HS2 & no money. Also please explain how NR received an initial £48bn for CP6 back in 2019 if HS2 was “hoovering up funds”. As for value, as seen with existing lines, heavy capital costs are made back over the lengthy operational timespan
Remember that parts of today’s WCML are almost 200 years old. How many times has that paid for itself over & over & over again above its initial costs? Also, what’s with a #Green going with the austerity rhetoric?? We can’t afford not to decarbonise, at any cost, esp public spend

🚨⚡️FULL TECHNICAL REPORT RELEASED⚡️🚨

Today, we have released our full technical report on the "Why Local Solar and Storage Costs Less". Two weeks ago, we released the main findings: savings of $473 billion when co-optimizing distribution. This released provides more details!
The report, ES, summary presentation, and spreadsheet can all be found on our website: vibrantcleanenergy.com/media/reports/ #energytwitter #cleanelectricity
The full technical report shows that the cost savings comes from lower distribution spending and higher utilization of variable renewables. The additional costs of local solar and storage are much lower than the benefits unlocked. #energytwitter

Great event and panel put together by @livemint @UtpalBhaskar converging diverse views from financing, #fossilfuel generation, #energytransition #technology and business operations in the #electricity value-chain! 1/n
As Power Minsiter @RajKSinghIndia rightly said, problems of capacity and #energyaccess has been solved, and the next problem to be solved is reducing #India's #carbonfootprint - #electrification of #mobility and #cooking is one pathway.
Increasing domestic and international demand for #electricity will lead to more #RenewableEnergy capacity installation; new connections and usage will ⬆️domestic demand, integration & #export (neighbors inc #Myanmar #SriLanka) will ⬆️cross-border demand, which India can supply.
