🌍 Our 2022 #Science Board Symposium on "The #Emergent #PoliticalEconomy or #ClimateChange" kicks off with opening remarks from President David Krakauer.

Follow this 🧵 as we provide live coverage of this event all day...
"For those of you who think behavior change can prevent #ClimateChange...behavior WILL change when climate changes. Shutdowns from the pandemic resulted in a reduction of #C02 emissions of about 7.5%."
- SFI/@Harvard Prof Dan Schrag opens our speaker series today
"We *used* to talk about #ClimateChange used to be something that would happen to people in Bangladesh fifty years from now."

Re: #ClimateJustice,
"Children born today are going to deal with climate change they had no role in causing."

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.

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:

In 2021, Europe imported ~158 Bcm of Russian #natgas.
By 2027, that figure is (supposedly) going to be 0 Bcm.

How do the Europeans get that done? Time for a 🧵
1/n Firstly, how does Europe plan to move away from Russian gas?

1. Moar US #LNG.
2. Increased energy efficiency.
3. More renewable energy deployment.
4. Healthy doses of optimism and idealism.

See @EU_Commission statement below.…
2/n Specifically, within the EU's statement is the commitment to increase LNG imports from the US by:

15 Bcm in 2022
50 Bcm by [2027]

Seems pretty doable? Until you actually dig into it.

NEW PAPER AND THREAD: Why are climate economists' favorite tools (carbon pricing/emissions trading) so despised?

@dolanecon shows where economists have missed the mark or failed to make themselves understood - and how they can do better.…
Are economists are wrong when they advocate carbon taxes/emissions trading as central elements of climate policy? Plenty of dedicated climate activists (some of whom are economists themselves) say "yes."
.@DrVolts writes that "climate economics and climate economists have blown it pretty comprehensively." @Noahpinion says that "climate economics has almost completely failed to be useful to the national policy discourse."……

In May of 2021, @EconTodd made a note of that morning's @WSJ headline during his interview with @stefan_wieler of @axpo — Russian troops had amassed on #Ukraine️'s border. Buchholz asked Wieler what that could mean for #gas and #oil prices.
@EconTodd @WSJ @stefan_wieler @axpo You can listen to his episode here for a little refresher:
Around the 20 minute mark, @stefan_wieler remarks on the lack of real-time #data in the #commodities space and the difficulty it creates for the #globaleconomy at large.

Only a few days into @COP26, we’re already hearing global commitments and plans. This will all culminate in a day dedicated to the built environment next week. In the meantime, I’ll share my #COP26 thoughts in this thread.
I encourage you all to explore this wonderful virtual exhibition of the world's greenest buildings at @COP26. These projects serve as examples to all of us in the real estate and building sectors. @wef…
As I’ve said many times, @COP26 must be a turning point for the real estate industry. Buildings are responsible for 40% of carbon emissions worldwide. Action from this industry is crucial to meeting climate goals.…

Carbon capture and sequestration (or CCS) is being touted by some as a potential solution for #decarbonization in industries like cement and steelmaking. But how promising of a solution is it? A deep dive 🧵
There is only limited experience with CCS at industrial facilities beyond gas processing. Only one steel mill in the entire world (and no cement plants), capture CO2. Little info is available about how much they capture, and key info about cost and reliability is missing. Image
Only 3 of 26 CCS projects currently operating in the world have reported any information that would allow their “capture rates” to be determined. Without this information, it’s impossible to show that any existing CCS projects are economically, financially or technically viable.

Have you read the @LancetCountdown’s new report on health and climate change? Check out @UHF_groups’ key takeaways 🧵👇
1) Climate change is impacting weather, #ecosystems, and human systems. This poses a threat to human #health. For example, young children, older people, and marginalized communities are more susceptible to health risks associated with high temperatures and #heatwaves.
2) High temperatures can reduce the frequency and duration of physical activity. Without #exercise, people are at a higher risk for cardiovascular disease, diabetes, and other #NCDs.

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.).… /3

(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%.

We finally published study on impacts of tightening the #EUETS in line with #EUGreenDeal on power sector #decarbonization…

In short:
1. Carbon prices in the ETS would triple to ~130€/tCO2 in 2030, effectively phasing out coal power in the EU by 2030

2. CO2 prices would also reduce gas-based generation by 40% in 2030 already

3. The power sector would reach zero emissions by 2040

4. Renewable share in electricity >74% in 2030, with average yearly wind + solar scale-up over 2020-2030 in Europe: 80GW/year

5. Balanced Wind / PV split, plus hydrogen electrolysis & turbines allow seasonal matching of demand & supply;
long-distance grids, batteries and hydrogen turbines manage shorter fluctuations

6. Unavailability of nuclear/fossil CCS power plants does not affect results

@NREL just dropped a new draft of its missing grid modernization study.
- Seams returns >2 years after Trump appointees squelched it
- 2 months after @INVW exposed their meddling
- And 1 month after @HouseScience told @SecBrouillette to #FreeSeams.
The #FreeSeams study projected that building a national power grid would cut costs + carbon by killing off coal and boosting wind & solar. The new @NREL Seams ordered by @Energy Dept politicos adds scenarios that "dilute" those findings. 2/7…
@NREL Seams' new DOE-approved scenarios assume:
- higher costs for power line construction
- lower fossil fuel prices, or
- limited retirement of coal generating stations

Each of those factors make long-distance power transmission look less cost-effective. 3/7

That`s why I am working at @Siemens_Energy: without us the sustainable safeguarding of our livelihoods is in seriously jeopardy, because climate goals could no longer be achieved.
This must be an incentive for us to play a decisive role in the transformation of energy systems and only as the leading stakeholder in hydrogen economy makes it perfect.
One masters the value chains in the power-to-X technologies even though they span from renewable energy generation, water, grid integration, electrochemical process technology to downstream logistics. Experienced players combine their strengths in one new entity: @Siemens_Energy
