This Friday, EU energy ministers aim to decide on measures to soften the impact of the escalating #gas and #electricity bills on households and businesses. The decisions should be guided by the following principles. A 🧵 1/10
Direct, timely & targeted payments to households & companies that need support are better than general public spending to lower energy prices for all consumers. The latter is very costly & can undermine the crucial need to save as much energy as possible before winter. 2/10
Current pricing mechanisms in #electricity market work and must be maintained. Marginal pricing is central to the integration of renewables and necessary to incentivise uptake of #heatpumps and #electricvehicles. Read more in our new paper (in German) bit.ly/3fs6Rmj 3/10

Q2: What’s the role of #renewables in Germany’s #powermix?

Wind & PV are the #Energiewende's backbone & the cheapest form of #electricity.

Power generation mix in 2021 (vs. 2000):
Renewables 40% (6.5%)
Lignite/hard coal 28% (48%)
Nuclear 12% (27%)
Natural gas 15% (9%). Image
In 2022, the share of coal has increased from 28 to 33%, compensating for the disruption of Russian gas imports.
However, the German government has stressed that this shift is temporary and will not adversely affect Germany’s #climatetargets.

One questionable idea from #SOTEU is the proposal to intervene in the #electricity markets rather than the #gas markets.

The EU spent decades building an electricity market to foster investment in #renewables, and succeeded

Doing this will likely destroy that market (1/n)
... because investors who turned to renewables will now see their profits capped while those who focused on gas will see record profits. This is compounded by member states rush to build new gas infrastructure to replace russian gas, and the taxonomy decision (2/n)
Von der Leyen's proposal will effectively remove all market incentives to invest in renewables on a large scale, and sends the market one clear message: invest in gas, that is where the money is.

So what should the commission hzv done? (3/n)

Welcome back! We’re going into the fourth hour of @BOEM’s hearing on its 2023-2028 offshore drilling plan, which includes up to 10 lease sales in the Gulf and one in Alaska. We’re tweeting live to hear why folks are calling in to #ProtectOurCoast & ask for #NoNewLeases.
@BOEM Juliana is from northern NJ, and reminds us that climate change has impacts across the country--like when the NY subway flooded. She calls for #NoNewLeases.
@BOEM Rev. James VanderWeele lives in Louisiana & is here to represent his grandchildren across the U.S.: What will climate change do to them? Will it force them to move?

Every greenhouse gas molecule increases #globalwarming. This is a moral crisis that will impact our grandchildren

Good chart to study: cost per MWh of #energy. Grey and orange balls are wind and solar; dark grey is gas; black is coal. Economic advantage of #renewables in most countries is stunning. Image

"figure 1.7 [shows] how large the benefit is by looking at the weighted average country #LCOE for #solar #PV and #windpower deployed in 2021 compared to what we thought the marginal generation cost would be for fossil fuels in 2022.
Put simply, renewables received their biggest yearly improvement in competitiveness in history in 2022.... the bulk of the boost coming from the eye-wateringly high fossil fuel prices we're dealing with in 2022.

I/others have talked a lot about this but it hasnt cut through, so here's a thread on why mandating all new build housing to have solar panels is virtue signalling, when there are far better options that deliver far greater decarbonisation results. #Solar #PV #EnergyCrisis
🧵
First, planning.

Often, builders buy an outline permission from a landowner, meaning they have to satisfy X, Y and Z to get on site. Often, this means the site isn't viable at the terms the landowner achieved.
Builders take that risk but sometimes govt changes regulations.
This happened recently, with Building Regs for energy efficiency, EVs etc adding between 10% & 30% to build costs. Builders hope govt is sensible with transitions..🤔
Those recent changes put Heat Pumps & Solar panels to the top of 'solutions to help meet regs' pile!

(1/9) I’ve seen a lot of op-eds about how awful it is that #CCS was included in the #IRA. Most lack nuance, because they haven’t clocked that the #energytransition isn’t just about the power sector anymore. Sorry #energytwitter. So, a 🧵 on why carbon capture still has a place.
(2/9) First, I get this. I was a huge #CCS skeptic. Two things changed my mind: modelling pathways to #netzero for materials with my @BloombergNEF team, and the #BNEFNEO team's carbon budgets for industry. Sobering work that taught me a lot.
(3/9) Some industries just can’t do without CCS. Process emissions are just as harmful as combustion. And we’re past the point where abatement of emissions is enough. That means removals, which means #DirectAirCapture.

"The key question around the #GreenEnergy transition is technological progress, and which technologies would improve..."
- SFI Prof J. Doyne Farmer (@INETOxford)

Follow this 🧵 for insights from today's seminar, streaming now on our YouTube channel:
"We're tracking the evolution of the global #energy landscape over about 140 years: which source is providing our energy, and how much is it providing us with?"
- SFI Prof J. Doyne Farmer (@INETOxford)

Speaking now:

#Solar #Wind #Nuclear #Oil #Gas #Coal
"#FossilFuels cost about the same now as they did a century ago. #Renewables have been dropping in price at rates of about 10% a year and deployment has been shooting up at about 30% a year, and this has been continuing for several decades."

The two thirds of households living in leaky homes face bills £1,000 higher than those in energy efficient homes when energy prices rise again in October to an average bill of more than £3,500. 🧵

#CostOfLivingCrisis #EnergyCrisis #FuelPovertyCrisis 1/n
With successive price cap increases, we could be looking at a £1,500 inefficiency penalty by April of next year if price cap predictions for £5,000 energy bills materialise. 2/n
Collectively in England alone, we face an increase in annual bills of £54 billion, based on expected price cap increase in October, compared with October 2021.

Inefficient homes are set to face £39 billion of the increase.

65% of households get 72% of the increase in costs. 3/n

🧵While it’s popular these days for Republicans to bash the #Manchin-Schumer proposal, look closer and there are things that pro-energy conservatives should like in the deal. Specifically:
1. #Drilling: significant increases in onshore and offshore drilling.

2. #Renewables: wind and solar subsidies/tax credits are contingent upon the granting of drilling permits (protecting against a Biden Admin "bait & switch").

3. #Nuclear: funding for nuclear investments.
4. #Carbon: funding & rules for carbon capture—allowing firms to keep current power plants open longer—giving the US a longer runway to reach its "energy transition" goals.

5. #Batteries: requires high levels of local material in production—curbing incentives to build in China.

Prime Minister Johnson has just signalled that the UK electricity market is about to undergo the biggest shake up since privatisation over 30 years ago. This will be a major test of their ability to do the right thing whilst keeping the show on the road 🧵
On @BBCr4today just now Johnson said one of the things to tackle cost-of-living crisis was to stop the ‘crazy’ situation that all electricity is paid for at the marginal gas price i.e. it’s all paid for at the price of the most expensive that fulfils UK demand at that moment

A 🧵 summarising the target to limit global warming to 1.5°C above pre-industrial levels …

First I’ll establish the importance and requirement of this goal and then point key steps for achieving this.
Where do current policies take us?

Assuming annual CO2 emissions increase to 36 GtCO2 by 2030 and plateau afterwards (with declining trends in developed economies), we are looking at 2.7°C by 2100 based on existing policies and Paris pledges.

Source: Net Zero by 2050 - IEA
Why 1.5°C instead of 2°C?

Heat Waves and Sea Level Rise

• 3x more people exposed to regular severe heatwaves under 2°C than 1.5°.

• SLR cut by 10cm under 1.5°C v/s 2°C. Robust increase in heavy precipitation intensity for high northern latitudes.

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"

⚡️NEW REPORT⚡️:
Our new modelling report from @DavidSuzukiFDN shows that 100% zero-emissions electricity across Canada by 2035 is possible, reliable and affordable.

Buckle up for a #CleanElectricity thread 🧵

bit.ly/CleanElectrici…

#Climate #energytwitter #cdnpoli
This is the first modelling report of its kind in Canada. It goes beyond #NetZero to reach #ZeroEmissions by 2035, primarily by relying on:

☀️#Renewables like wind & solar
🔋#EnergyStorage
🏡#EnergyEfficiency
🌊Existing #Hydropower
🔌More grid connections between regions
Overall, Canada's electricity capacity grows by 2.8x by 2050, and the amount of electrical energy we use grows by 1.8x

All #FossilFuels on the grid are phased out by 2035, including all #NaturalGas. And no nuclear or fossils with #CCUS are needed.

UPDATED COUNTRY ANALYSIS: Australia has made very little effort to increase #climate action & is refusing to increase the 2030 target it first submitted 7 years ago, in 2015. Its plans won't meet 2050 #NetZero target. We rate it "Highly Insufficient" bit.ly/CAT_AUS /2 Image
For its policies & action, we rate Australia "Insufficient". While the govt insists it will overachieve its 2030 target, it didn't submit a stronger target to which it would be bound. Current policies result in 2030 emissions excl LULUCF 15% below 2005
bit.ly/CAT_AUS_polici… /3 Image
#Renewables in the power sector alone are projected to reduce emissions (excl LULUCF) by 20% by 2030 from 2005 levels. But as there are no policies to reduce emissions from stationary energy or transport, fugitives are projected to INCREASE emissions by 9% above 2005 levels. /4

Leaked #RepowerEU draft:
o -13% energy demand 2030 (vs -9% prior target)
o 45% energy from #renewables 2030 (vs 40%)
o x2 today's #solar by 2028
o Greater use of heat pumps, geothermal & solar thermal
o #Wind build-up to be “drastically accelerated” 1/2
on.ft.com/3yvikZN
Leaked #RepowerEU draft on #hydrogen:
o 20Mt demand by 2030 (already known)
o 10Mt from EU + 10Mt from non-EU
o Subsidies for EU & non-EU renewable hydrogen
o Three “hydrogen import corridors” via the Mediterranean, North Sea and, eventually, Ukraine 2/2 ft.com/content/2aef06…
Bonus: the three "#hydrogen import corridors" are aligned with the analysis in our report on the Future of Renewable Hydrogen in the EU, in which countries in North Africa, Northern and Eastern Europe were identified as key suppliers for the EU: belfercenter.org/publication/fu…

“interconnection queues” and obtaining the necessary #ImpactStudies and #permits from #each grid operator has risen from around 2.1 years for projects built in 2000-2010 to around 3.7 years for those built in 2011-2021.

#decentralizedgrid issues are key.
wired.com/story/everyone…
"researchers found that only 23% of the projects seeking grid connection between 2000 and 2016 have actually been built."

“The grid operators have limited staff to conduct these studies,”
“Maybe they haven't ramped up their workforce quickly enough.”

#Gridlock
#SkillShortages
The inability of #renewables to deliver #LargeScale solutions may NOT be due to #financing constraints. #Regulatory ones matter too.

As prices fall, the gap btw #LevelisedCostOfEnergy for #Rooftop and #SolarUtility shows, scale matters.
Alot.

One of the key insights form the latest @IPCC_CH report: A lot can be done now at reasonable cost. Here is my summary chart with five key insights.
@WWF_Schweiz @ETH @esc_ethz_ch @economiesuisse @MercatorCH @_climanow @fabianetter @klauseram @elia_bluelle
1) The first quarter (23%) is a no brainer: Costs of low and zero-carbon techs to reach net zero are lower than the reference tech. This is mainly energy (think #renewables) and transport (think #EVs).
2) Roughly half of the required mitigation to reach net zero has costs below the median internal carbon price of European companies, which use a carbon price (see @McKinsey mckinsey.com/business-funct…).
