I wonder why they called modern bi-xenon or LED bulbs 'Net zero bulbs'? [sarc]

So why are UK electricity bills so high?
It's got nothing to do with the amount of wind and solar generation!

I took two of my sons and my grandson on my regular (typically 4 x a week) walk on Dartmoor today. This is the isolated tor called 'Branscombe's Loaf'. The windiest and coldest walk this Autumn so far.

If instead of putting renewable electricity straight into the grid you use it to make green hydrogen, you lose ~one third of the embodied energy. Burning that hydrogen in a power station increases the losses further and is a fine example of madness. www.carboncommentary.com/blog/2021/6/...

Gas explosions in domestic properties in the UK are a regular occurrence. This is one which killed a child in a neighbouring house.

This is the picture I use. This is what Nigel Farage wants the UK to look like when he allows fracking. I don't think people realise the density of wells needed to extract gas from an area.

If you have opinions about #HeatPumps not being suitable, being more expensive to run or not working in certain types of property, in certain weather conditions or below certain temperatures, you might find the following enlightening. interactive.carbonbrief.org/factcheck/he...

Certainly was a lot of rain around midnight. Made up, to a small degree, for a spring and summer of very little.

Given Reform are so 'nimby' about solar and wind turbines it's hard to see how #fracking could succeed in the UK, given how it trashes the landscape. The Tory Gov researched and dropped it. Even Cuadrilla's boss agrees: www.theguardian.com/environment/...

Some simpleton has daubed a red cross on the mini roundabout in the centre of our village in rural #Devon.
Is this all to do with immigration, Farage and Reform?

One of the very first tweets I posted on Twitter when I joined in 2011 was this picture below, saying we depend for life on that thin yellow atmosphere that we're polluting with CO2.
So, yes, I too realised how important the planet was without needing to spend 6 months orbiting it :-)

The boulders can be clearly seen here in Black-a-tor Copse. These woods are constantly trying to expand by dropping spreading seed but the young trees can only survive where the boulders (or fences) protect them from grazing sheep.

Let's not beat about the bush. Some, lacking evidence, and driven—one must presume—by ideology, have already lied about the cause of the Iberian Peninsular electricity blackout.

I've been waiting for the Met Office to publish this anomaly map.
It's been incredibly dry in the south west of the UK during March. And it seems there's no significant rain coming for at least the next fortnight.

I'm this old. In case you don't know it's a comptometer (so old it's underlined with a wavy red line because the spell check has not heard of it). You'll find more here: en.wikipedia.org/wiki/Comptom....

My God, that's a bloody thin bat of loft insulation. The ones I've used from time to time are 6" (150mm) thick. And then I double them up where there's room! The regs now for a loft are saying...
