With zonal market reforms ruled out and a whole bunch more renewable generation on the way, failing to do more to upgrade the grid over the last decade is becoming increasingly costly. These network projects now really do need to happen as fast as possible.
NAO report on rising constraint costs and the pace of grid projects, plus the headlines it has triggered, will have alarm bells ringing in government. Although in fairness they have been ringing since day one. www.businessgreen.com/news/4535591...

Have been very much out of office on a hiking trip for the past two weeks but now I’m back I’m excited to share a bit more about this new research. Short version: electricity demand for heating and cooling (particularly on peak days) looks set to rise basically everywhere in coming decades. (1/n)
As the heatwaves keep on coming this summer, I have a timely new @granthamlse.bsky.social working paper out today (joint with Maren Ludwig at UC Berkeley). We show how economic development, climate change, and decarbonisation policy will reshape global electricity demand for cooling and heating.
The global consequences of climate change and appliance adoption for peak electricity demand - Grantham Research Institute on climate change and the environment
In this paper, the authors estimate the global impact of changes in electric heating and cooling demand on the electricity grid in the coming decades.

I don’t know, the utility company probably had to secure some costly debt/equity investment to fund that air fryer. Would have loved to hear them argue for its inclusion ☺️

To be expected from Reform, but this is a bit embarrassing from the Greens.
Any decision like this always comes with some tradeoffs and solar farms are not some sort of panacea. But opposition is too often based on the same old arguments. Let's have a look at some of the points raised... 🧵

Glad to see LSE speaking out on this. Recent government actions are more than just benign neglect. To name a few: taxing a key export sector, whittling away direct funding (was 40% in 2010 now 10%), fees capped in nominal terms, restrictive immigration rules, and an unjust loan system for students.
Glad someone senior from the sector is pushing back. Labour MPs need to understand the serious real anger from graduates and the people who produce them. And the dangerous financial situation they have allowed to fester, or indeed worsened, in one of Britain’s leading sectors.

I think those who (often fairly) criticise the media's picture choices at times should *also* point out that press photographers have in recent weeks given us some of the most incisive views of the climate crisis that we've ever had.

Lots of talk about data centers pushing up prices, raising emissions etc. But an issue I've been wondering more about is resilience.

EU ETS reform proposal is out, with the usual reactions of how @ec.europa.eu now, too, is backtracking from its climate commitments.
Headline: free allowances through 2037, not 2034.
Except allowances now come with strings attached: spend on decarbonization.

Persistent, terrible air quality from wildfire smoke is such a miserable, worrying new reality.
I remember how bleak the California Bay Area was in 2020 - the red sky with street lights on at midday. I remember NYC in 2023. And now this morning I've woken up to find it has descended on DC.

To add some data to the debate, here's a map of residential AC uptake around the world from some forthcoming research.
Given the temperatures now regularly being experienced, people in Europe really just don't have a lot of AC.
