THREAD: A heat-pump tumble dryer could save households more than £700

Lots of overblown reaction to govt phasing out standard dryers – reminds me of when 2009 Mail frontpage wailed about "beloved" incandescent bulbs

But heat pump dryers are just a much better technology

COP30 BREAKING NEWS

The presidency has just dropped a new package of texts including the "global mutirão" cover, which makes no mention of fossil fuels or roadmaps

Oops! The Times has had to issue an embarrassing correction over supposedly "sluggish" EV sales 😳

❌ It said EV sales to private buyers fell 10.8% this yr
✅They actually GREW…by 62%

Yet Times articles still claim a "big fall", "collapse" & "slide" in private EV sales 🤔

Still, emissions would need to fall even faster to meet 2035/2050 targets

Gas demand fell overall but there were competing trends…

* Gas for heat was up despite warmer temps, likely due to lower prices
* Gas for power down, replaced by low-carbon sources + cheap imports

Another 1/3 of drop in UK emissions in 2024 was due to lower demand for oil & gas

Oil dropped 1.4%, despite higher traffic, as EVs ate into demand for petrol/diesel

* EVs on the road up 40% in 1yr (!)
* EV drivers saved ~£800 each
* Total saving ~£1.7bn in lower fuel costs

* One-third due to end of coal power

If this chart says to you "the climate/1.5C was screwed either way", then you've missed a fundamental truth about global warming:

–every fraction of a degree matters
–every tonne of CO2 counts
–every delay makes escalating climate impacts on people + planet harder to avoid
