UK PM @BorisJohnson will soon set out an energy security strategy. The biggest, quickest action 🇬🇧 can take to wean itself off Russian gas and expensive #FossilFuels is to invest in home #EnergyEfficiency and renewables. AN ENERGY SECURITY STARTS AT HOME TOP 10 FACTS THREAD 🧵
Fact 1/ Nearly 90% of the increase in bills over the last year is due to the rising price of gas, which has more than tripled over the same period. Most of the remaining increase is the cost of suppliers going bust.…
Fact 2/ The UK has the oldest, most poorly insulated housing stock in western Europe, and over 85% of our homes are connected to the gas grid – leaving UK families sharply exposed to the volatility of international gas markets.…

[#FakeNews] Regardons de plus près les positions du @_Cereme_ dans son quiz sur l’#éolien, un « think-tank visant à promouvoir un débat objectif sur le choix du #mixénergétique en 🇫🇷 » 🤔⬇️ THREAD…
L’#éolien est une énergie faiblement émettrice de #GES. @RTE chiffre les émissions évitées grâce à éolien & solaire à environ 22 millions de tonnes de CO2/an ! La moyenne d’émission du parc éolien est de 14,1g CO2/kWh VS #charbon 👉 1001g de CO2/kWh
[#Recyclage] Auj. plus de 90% d’une #éolienne est recyclable ♻️ Il n’est en aucun cas possible de mettre en décharge les pales des éoliennes dans un pays de l’UE ou d’abandonner des éoliennes sur le territoire français ⛔️

What are retrofit options for someone with 90-100m² ‘hard to treat’ home, concerned about rising gas prices and the planet? Installing a heat pump is single largest measure for lowering the carbon footprint, but how soon to fit one on retrofit journey? #retrofit #heatpumps 1/
Doing nothing on fabric or gas means bills will escalate
and there is a serious risk that such a home will have lower resale value in the future. By starting to think about retrofit, home owners might do things they have put off for years, like clearing the loft. /2
Getting off gas early prioritises planet, without bills needing to rise.
Install ASHP early alongside
Limited fabric measures, such as loft insulation to modern std; seals / brushes for doors / sash windows for drafts (and cavity wall insulation added if applicable) 3/

We need to #retrofit 2 homes a minute by 2050, says @AskNationwide.

25+ industry orgs have joined our 5 asks for government to unlock a self-financing deep retrofit market that can deliver warm & affordable homes for millions▶️ #DontForgetRetrofit #COP26 Energiesprong UK's 5 asks for government to unlock net zero
1⃣ #NetZero target for homes - now. 🏡

Stepped targets are creating a piecemeal approach to #retrofit that costly & difficult to finance.

A clear target for net zero homes ensures investment in cost-effective retrofit and industrial innovation. #DontForgetRetrofit #COP26 Energiesprong UK's 5 asks for government to unlock net-zero
2⃣ £250 million innovation investment.💷

5 – 7 years of innovation funding following the “commit and review” Offshore Wind Accelerator arrangement could:

▶️kickstart a self-sustaining market
▶️deploy existing methods to alleviate fuel poverty.

I'm in the middle (well, actually still close to the beginning! 🤣😬) of an #EnerPHit #Retrofit of a 1970s timber frame 🏠 in the W Highlands of 🏴󠁧󠁢󠁳󠁣󠁴󠁿. I've decided to tweet this as one long (hopefully ~1yr from now) thread. Buckle up for the ride! #TimberFrameRetrofit #Passivhaus Image
And some folk who've expressed an interest in previous threads (feel free to stop notifications on this if you're not interested):

the proxy design pattern is a super useful one in @Java.
The idea behind a proxy is to make it more transparent to work with remote resources. They're all over the place in @Java and enterprise Java, in particular. I'm going to look at some of my favorite examples in this thread
Spring Integration supports messaging gateways through proxies: inject a reference to Cafe, invoke that method and a Message<T> with the payload Order gets sent on the orders MessageChannel (and then to anywhere ya like)

(1/4) There has been a lot of chat this week about the cost of #retrofit #heatpump installs. Here's an installer's view on the three types of costs that drive it - 1. Costs that won't change 2. Costs that intervention could change 3. Costs that will change as the market grows.
(2/4) The first time you retrofit a #heatpump it will always be more expensive than a new gas boiler. You have to put in a new hot water tank, run pipework outside, build a base for the heat pump, ensure radiators and pipework are adequate. These costs vary from house to house.
(3/4) There are also costs that government action could reduce: streamline the process to connect to the electricity grid; invest in training installers; mandate low temp boiler installs; make the planning conditions more sensible (1m from property boundary, why 😡?)

Recently, I was asked to give a seminar for @mhclg’s planners on the challenges faced by local authority planners delivering against the #climateemergency, because I work with lots of councils & I’m also Cabinet Member for Forward Planning at @CotswoldDC. So I know some stuff.
First up, I did the ‘we’re all doomed’ bit. You know, the rollercoaster graphs steeply going up and the even steeper graphs of how emissions need to come down.
Then I mentioned about how most plans are running for about another 10-15 years and they need re-writing immediately because most of them pay diddly-squat attention to the ‘what goes up must come down graphs’ from the ‘we’re all doomed’ bit.

You may have heard that the @UKLabour Labour Party plans to scrap the Married Couple's Tax Allowance if they get into power. Attack ads are being shared on Facebook by the Conservative Party arguing that people will be worse off because of this. Here are the facts:
Maximum tax allowance available through the Married Couple's Tax Allowance is £250 a year. BUT…
Every Married Couple will be BETTER OFF under @UKLabour Labour - because: - and here are just five of the ways:
1. People on the #MinimumWage wage will get a minimum of £3,400 more a year,…

#energytwitter @exeterepg @EnergySysCat @EnergyLeeds @EnergyREV_UK @NatureEnergyJnl continuing our energy #ideology theme for the week, we know ideology is a fundamental determinant of whether and if we legislate for an #energytransition…
So overt questions of regulating energy in capitalism are legit terrain for a partisan empirics of energy research. But are we aware how much we enjoy our own more private ideologies? Reactions to @UKLabour energy policy are fascinating.
Responses to a #GreenNewDeal scale home retrofit programme "I already paid to insulate my home [individual responsibility trope] why should I pay for my neighbour's loft insulation [feckless socialist/free stuff trope] even before the finance mechanism is announced.

My quick THREAD 👇 on a few developments in buildings which you might have missed, but which *could* be transformational.

Covering #PAS2035, a few gems from the #GreenFinanceStrategy and the forthcoming electrification demonstrator... (1/8)
1. Last week's Govt Green Finance Strategy contains some stuff which would have been in the 2018 Energy Efficiency Action Plan. BEIS & HMT commit to consult on measures to get mortgage lenders to disclose the *average performance* across their portfolio -cf 🚗fleet average (2/8)
This could pave the way for future regulation, building on the v successful NABERS model pioneered in Melbourne commercial offices &covered in @theCCCuk 2016 Heat report (supported by #Betterbuildingspartnership in the UK) (3/8)

#NetZero target is incredibly welcome to focus minds so, from our work on over 3 million homes so far, here is what we have learned so far about the Home Front in the #climateemergency THREAD 👇
1. Carrots and sticks: Legal targets cut through ROI & get #retrofit to top of agenda. The #CleanGrowthStrategy targets are already driving investment amongst our public and private sector clients and action will accelerate once the standards, and their enforcement, are clarified
2. Sell the sofa not the finance: Of the carrots, our research amongst home-owners shows there is appetite for good-value #retrofit finance to overcome upfront costs, but the rest of the offer has to appeal first. Again, multiple levers are needed.
