What does EU's impact assessment mean for the electricity sector? Well there's only 1 graph to really any insight, figure 46! #FitFor55...

STEP 1: Use a graph grabber to get the numbers! (the Commission will hate me for doing this!!!!)....

ec.europa.eu/clima/sites/cl…
ELECTRIFICATION?

By 2030: EU elec demand will only rise by 9-11%. Major electrification in transport+industry+heating is partly offset by major efficiency.

BUT by 2050 elec demand will more than double!

(this graph is derived from Commission graphs from figure 46!)
BIOENERGY?

Reassuringly, there's little growth, except for power.

Power grows a little to 2030, then LOADS from 2050.

In figure 46 above, “other renewables” electricity increases by 100TWh by 2030 which might be bioenergy? I wonder what type that is?
RENEWABLE ELECTRICITY?

It means that renewable electricity needs to accelerate from 29% of the mix in 2015 to 61-69% in 2030…

So much to say on this one graph, i won't even try!
FOSSIL ELECTRICITY?

Fossil generation will more than halve, from about 1300TWh in 2019 to 480-629TWh in 2030… This means not only coal generation is falling, but gas generation will fall as well…

In 2050 (not in graph), it's negliable.
Does that mean a 2030 COAL PHASEOUT?

No, they expect some coal running in 2030.

They say “Coal consumption would need to be reduced by 70%” from 2015 to 2030. Since c.80% in 2015 was used in power plants, some coal generation will exist in 2030.

But we know it won’t be a lot.
CARBON PRICING?

It's reassuring #EUETS prices are not crazy high!

Key scenarios are in the range €32-€44 (in 2015 prices), slightly higher than baseline of €32.

Hopefully this might reassure Poland, Czechia, etc, that 55% ambition is more affordable than they assume!?
Oh dear, i feel like this analysis is only 0.0001% of the overall analysis released today...

Here's their full release...

NEW: Cheaper batteries mean near-24/365 solar is now economic☀️

We analysed 18 years of hourly insolation data at 12 places, to see how close to 24/365 electricity it was possible to get.

The sunniest places get over 90% - and up to 99% - of the way... from just $100/MWh. 🧵 Image
We launched it today (on a Saturday!) because today is the Summer Solstice in the northern hemisphere, and you could theoretically generate 24-hour solar in the Arctic tonight without battery!

(tenuous rating: 8/10) Image
Getting to 24-hour solar is easy tho: just add battery!

Getting to 24/365 solar is hard cos of pesky clouds - and batteries aren't economic to store electricity between days.

Fortunately though, even on "cloudy" days, you often still get more solar power than you might think.. Image

OUT TODAY: How is the US electricity transition doing?🇺🇸🧵

WIND+SOLAR OVER TOOK COAL: Wind and solar now at 17% of US electricity supply; coal falls to a record low of 15%.

Only 6 years ago in 2018, coal generation was x3 that of wind and solar🤯 Image
Wind and solar generation has now overtaken coal in 24 states💪

Illinois was the latest to join the ranks in 2024, following Arizona, Colorado, Florida and Maryland in 2023. Image
Solar was the star, rising 27%⭐️☀️

Incredibly, 32% of California's annual electricity supply and 30% of Nevada was from solar. That's higher than any country in the world!

Yet 28 states generated less than 5% of their electricity from solar in 2024🌖 Image

🚨🚨WAKE UP CALL 🚨🚨

Soaring electricity demand means global coal demand **may** no longer fall in the coming 3yrs.

This is a big change in prognosis from just 12 months ago.. 🧵 Image
The revisions for global coal demand have increased quite sizably.. Image
Coal demand is VERY sensitive to electricity demand.

A rise of **just 1.2pp** in global electricity demand in the IEA in the next 3-yr period led to a **3.4pp** rise in total coal demand.

(Makes sense - coal is 1/3 of elec demand; RES+nuclear+gas forecast is unchanged) Image

This graphic is going viral.

This is how it was calculated... let's get geeky🤓... Image
It's based on this table in today's IEA report.

Solar is x100 coal because...
- SOLAR: 2GW x 17% utilisation x 40 years = 120TWh
- COAL: 150kt x 8MWh/t = 1.2TWh (note this *energy* content of coal; you'd need x300 as many ships for the same *electricity* content as a ship of solar panels)

Notes on solar:
- The "40 years" and "17% utilisation" is what i've used to backcalculate their x100 calculation and show they are reasonable calculations.
- A container ship is assumed as 15000TEU, far short of the largest container ship at 25000TEU.
- 2GW across 15,000TEU means there's 133KW of solar panels in a container. Useful to know:)

iea.blob.core.windows.net/assets/48d2ba3…Image
Interestingly, battery takes up even less room...

If container ship has 2GW, then for 4 hours of storage, you need 8GWh of battery - which is less than a third of a container ship... Image

The IEA's #1 flagship report, and the bible of the energy transition.

So, what's new? My key takeaways...
We are firmly in the Age of Electricity💪 Image
Electricity demand has been revised up.

Previously, it was 2.7%/year to 2030 (the same as for 2010-2023), now it's 3.3%/year.

And demand growth is coming from EVERYWHERE - yes data centres + a/c, but also EV's+heat pumps, and industry is actually the biggest slice... Image
