Time to Stop Rolling Dice: Why Bigger is Better in Climate Investments
Earlier investments make large-scale emission reductions easier to do over time because their unit costs drop

I woke up with an idea for an article on how pseudo-intellectuals are taking up the space in the public discourse that was previously occupied by genuine intellectuals.

Working title: "The Midwit Cuckoos".

I won't get round to writing it, but maybe @robertshrimsley.bsky.social might

Energy Institute stats review for 2024 is out: and #wind & #PV continue to be the fastest growing sources of clean energy that the world has ever seen.

And, as is normal for PV, we're soon going to need a bigger scale on the y-axis.

Here's a fascinating read, and a substantial bit of research, on the history of decision-making rules at COP. On the consensus imperative, how it came about, and when it has (and hasn't) been interpreted to mean unanimity. www.carbonbrief.org/guest-post-t...

Guest post: The challenge of consensus decision-making in UN climate negotiations - Carbon Brief
COP decisions are always adopted by consensus. How has consensus decision-making played out over the decades during UN climate negotiations?

Short-haul flights are a tiny fraction of total emissions.

AND

Short-haul is where innovation is happening. Forcing it to go clean, will bring long-term benefits across the whole sector.

So don't ban short-haul outright. Ban short-haul that burns fossil fuels. Encourage innovation.

#energysky
As a counterpoint, here is our own study that found out that even banning all super-short-haul flights in Europe would bring about very little emission reductions, as most aviation emissions are from long(er) haul t.co/Zhmg03Dt3h

I highly recommend following my favourite stand-up comic working in climate mitigation.

But I do notice how dark the days are getting, when even *he* starts channelling Albert Camus.
COPs are like birthdays in that celebrating each passing one seems stranger as we edge closer to death. Yet it is all we can do. We go again.

Characteristically, @hannahdaly.bsky.social is asking the crucial question. Because if we don't view heat decarbonisation as primarily a *systems* question, we WILL screw up.
By 2050 we see ~90 PJ/y residential water & space heating demand, and ~300 PJ/y total electricity (~3x today).
🧵1/4
With future power grids running on high shares of variable RE, we have a huge energy storage problem/opportunity. Storing electricity as heat can be super efficient over long periods, if its final destination is heat. My question: how to realise this value and couple the systems?
