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

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 🤔

The UK's emissions in 2024 were 54% below 1990 levels, while the size of the economy has nearly doubled over the same period
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
* LNG imports halved, cutting 1.5TWh off demand for regasification

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

Falling steel prices due to supply exceeding demand are causing havoc for global industry, from UK to South Africa & even China
So not at all clear Port Talbot's blast furnaces could've been saved…either way Tata's pledged £1.25bn for electric arc furnaces at the site

Drop in steel production was due to closure of final blast furnace at Port Talbot steelworks in Wales and pause in production at Scunthorpe works
No other stuff didn't help, but worth noting big drop in steel prices in past couple of years due to flooded global mkt…

UK coal use fell by 54% in 2024 to 2m tonnes, the lowest level since 1666
Of this…
* One-third due to end of coal power
* Two-thirds due to lower steel production
This accounted for around half the drop in UK emissions overall

UK electricity generation from fossil fuels has more than halved in a decade, falling to 91TWh in 2024 – the lowest level since 1955 and making up the lowest ever share of the total, just 29%

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
