Take 15 mins. Watch this video. It's more important to you than you know.

This is what China is doing, but Western governments are on exactly the same path #technologically; they just have a different set of #rationalisations.

The #DatabaseState isn't coming. It's already here.
It doesn't matter if your Government's #justification is #innovation ("AI is cool!"), #PublicSafety ("Think of the kids!"), or #efficiency ("People are expensive, let's use algorithms instead") - installing the #tools of #totalitarianism only ends up in one place.

It was true...
...of @ukhomeoffice's centralised #biometric National Identity Register - the heart of the #IDcards scheme in the 2000s - and is as true of @DCMS's "Identity & Attributes Trust Framework" 👇 of which the first 'adopters' include the #HomeOffice (again)...

The @EnR_Network held its first in person meeting in over 2 years in #Lisbon. After a first day of fruitful discussion on collaborative action between Energy Agencies, today, the network held a seminar on #energy and #water #efficiency at national and local levels.
The President of @EnR_Network, @nelsonlage highlighted the role of energy agencies in the #GreenTransition, as enabling agents acting between international and local level, to balance the three dimensions of the #EnergyTrilemma: Security Affordability #Sustainability
Sec of State @Joaogalamba described the vision for national-local level governance towards #NetZero in 2050: "energy agencies work to mobilize local authorities, economic players, and citizens to fight #ClimateCrisis, to foster cities’ pivotal role to deliver the #EUGreenDeal"

#Reichweite

- wie weit man mit 100 € kommt:

382 km ⬅️ Porsche Cayenne S
556 km ⬅️ VW Golf R
658 km ⬅️ MINI Cooper S
1732 km ⬅️ Tesla Model 3

#Efficiency
Kosten:
2 € / l bzw. 0.35 € / kWh.

Verbrauch per 100 km:
13.1 l ⬅️ Porsche Cayenne S
9.0 l ⬅️ VW Golf R
7.6 l ⬅️ MINI Cooper S
16.5 kWh ⬅️ Tesla Model 3

* alle Modell als "Automatik"

Quelle für Verbrauchswerte:
fueleconomy.gov/feg/Find.do?ac…
Anmerkung:
Die Verbrauchswerte sind von der o.g. Quelle.
Selbst wenn man für den Tesla 18 kWh/100 km nimmt, was einem nicht ganz so sparsamen Fahrstil entspricht, erhält man eine "Reichweite" (in diesem Sinne) von 1587 km.

Tomato, Pomodoro!I've been using the Pomodoro technique recently to increase productivity.When I mention this to people the response is "Pomo-whatnow?!"I thought I would provide a summary in a thread. Read on for a primer of Pomodoro & how it may help you level up productivity 1/
2/
In the late 80s Italian-German uni student & programmer Francesco Cirillo began timeboxing work & study into small 25min blocks. He tracked these using a tomato shaped timer, called a Pomodoro, Italian for tomato. Shared widely in the 90s he published a book on it in 2006.
3/
Enough history, what does it actually involve and why does it work so well?
The process is pretty simple:
1. Get yourself a timer
2. Write down a to-do list of items you need to complete

Starting a human or machine-based process late and finishing it quickly is also a sign of labour or robotic #efficiency, which is not taken into account by organizational #productivity specialists.
Doing things correctly matters without wasting time
#gembawalk #Lean #Agile #TQM
Arriving at 9 in the morning at the office and staying late beyond designated working hours is the worst kind of employee #attitude, which should be rebuked by the #HR Dept.
Why do some people stay late at work, anyway?
Spying? or other motives?
Surprisingly, I have come across some night shift workers who do fewer hours and are at times far better at producing results compared to daylight sleepy heads.
More organizational studies are required to check employee motivation, productivity and time-task assignment management

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 weforum.org/agenda/2021/11…
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. businessinsider.com/sustainable-co…

Well, breaking news will now keep coming every day ahead of #COP26 but this one could have MASSIVE implications for global energy markets & #fossilfuel demand: #China announces first details of its carbon neutrality framework aiming at #netzero by 2060 1/5 gov.cn/zhengce/2021-1…
The document introduces several consumption "peaks": peak #coal by 2025, peak #oil during the 15th 5-yr plan (2026-2030). Food for thought for #China's largest oil suppliers #SaudiArabia, #Russia, #Iraq, #Angola, #Brazil; and coal suppliers #Russia, #Indonesia, #Australia. 2/5
Energy #efficiency is one of the highest priorities. 2025 target is to reduce energy intensity of GDP by 13.5% compared to 2020 (note, the baseline is the COVID year)! New standards and certification to be introduced for #steel & other energy-intensive industries. 3/5

Limitations of an Optimized Mindset
A thread 🧵on the problem of optimization!
1/ Finding an optimal solution through an efficient algorithm is how a trained technologist looks at any computational problem.

But as soon as this mindset is extended to real-world problems, the majority of inefficiencies become annoying.

#solutions #efficiency #productivity
2/ In fact, the real problem starts when everything in life becomes an optimization problem.

So much so that eventually, it becomes a defining orientation to life as well.

The Concord project opted to go with Solar (PV) connected to an energy storage system (battery storage) in lieu of a backup generator.

This system has been designed to keep the critical loads for the home operational even if the utility power is knocked out.
This includes the backup heating and domestic hot water system (gas boiler with radiant floor heat + indirect hot water tank), the refrigerator, freezer, microwave, TV/WiFi, lighting and receptacles in strategic areas.
The Generac PwrCell provides 18 kWh of battery storage in a single cabinet, and up to 9 kW of continuous power output, enough to power the critical loads for extended periods of time. It can also be expanded to 36 kWh of battery storage in the future should it ever be needed.

My take on @ivanlpenn's & @ckrausss's @nytimes: nytimes.com/2021/07/11/bus…
TL;DR: #transmission (trX) vs. rooftop #PV (rPV) dilemma = unfounded, poorly scoped article, misrepresented study, romanticized rPV, pessimistic trX, obsolete #energy policy references & more! -1/n
First of all, rPV & trX are largely UNRELATED. rPV increase energy #efficiency & (might) offer #energy #resilience . trX reduces energy costs, increases #reliability & expands access to electricity market for all. -2/n
An important aspect is that rPV comes mostly at personal high upfront costs, while trX investments are "socialized". I.e. rPV is not for everyone, while trX is driven by broader energy concerns of wide social impact. Here is the article's first miss!.. 👇 -3/n

It was a good to join @TheWorld’s @MarcoWermer and @BTI's Zeke @hausfath to question the compatibility of our relentless #GrowthDependency and achieving carbon targets. A few reflections on the discussion in this thread 1/7
pri.org/file/2021-04-3…
We all agree that rapid absolute #decoupling of emissions (not to mention impacts on #biodiversity etc) is necessary. And possible. By investing in cleaner technology #renewables #efficiency #circulareconomy #greennewdeal @AOC 2/7
Our disagreement arises from whether technology is sufficient to achieve what’s needed – to stay within 1.5 degrees for instance – without challenging @GretaThunberg’s ‘fairytales of eternal economic growth’ #theredqueen 3/7

Email productivity thread

Gaining proficiency with MS Outlook has been really important in helping me accomplish as much as I have.

Now, I can usually process 200-300 emails in about 30 minutes. I’m asked frequently how I do it - I will try to explain in this thread.

1/
It starts with being able to search efficiently and accurately. For many many years, I didn’t know how to do this. I would type a few words in the search bar and then scroll the myriad of hits till I found what I was looking for.

There is a better way.

2/
First, go to options within the file menu and change your search setting to search all outlook items, not just the current folder. This will save you from having to tell outlook you do it with each individual search

Is #concentration rising? @AffeldtPauline, @JoannaPiechucka, #KlausGugler and I use a novel dataset containing information on over 20,000 relevant antitrust markets between 1990-2014 to assess this question: cepr.org/active/publica…. We find quite some heterogeneity. A thread 1/N
The extant literature measures #concentration using #industry classifications. Data are mostly aggregated at the national/regional level for all products. Yet, both the #geographic and the #product market definitions should be based on the #substitutability among products. 2/N
Our database identifies over 20,000 product/geographic #antitrust markets affected by over 2,000 mergers scrutinized by the European Commission between 1995-2014. This allows measuring concentration consistently on an economy-wide basis over time (diw.de/documents/publ…) 3/N

"When making decisions, instead of asking ourselves which option will give us the best results, we should be asking which option will give us good-enough results under the widest range of future states of the world."
psyche.co/ideas/why-effi… via @psyche_the_mag
"And satisficing with an eye toward a radically uncertain future might be called robust satisficing."

Good enough seems to be a better bet - especially as we become familiar with the variability and swift state changes common to #ComplexSystems
So much of #ResilienceTheory has led us to question our #DecisionMaking ; and the hyper-focused drive toward #Efficiency rather than #Resiliency

1/ For the #industry sector our #ParisAgreement sectoral benchmarks report focuses on #cement & #steel. All countries can reduce #cement #emissions intensity 90% by 2050. The #USA lags behind. Benchmarks don't differ much, huge progress needed. Full report bit.ly/CAT_PSR_full Image
2/ For #steel, all countries can reduce #emissions in this sector to zero by 2050 & aim for 25-30% by 2030. Huge scrap #recycling potential in #EU, #USA, #China. No new conventional steel plants shld be built. #Fuel switch to #hydrogen, #circulareconomy bit.ly/CAT_PSR1 Image
3/ #electrification of #industry combined with decarbonising the #electricity sector is critical. New tech, new materials & material #efficiency needed to decarbonise construction, or risk need for removing #CO2 from #atmosphere. Report bit.ly/CAT_PSR1  #circulareconomy
