It doesn't matter how vehemently or often or long something is said, if it aint so it is not so.

Here somebody with an actual brain and the career path to use that capability, lays it out : AGAIN.


It will not make one Nostalgic Nationalistic Nutjob of Nope2Woke difference, but at least it validates the truth _one_ _more_ _time_.

If heat pumps are part of the necessary green transition, then it is pretty clear the economic model for energy needs t change to make the switch a worthwhile project for households.... certainly they may be greener, but in the UK's economy, still experiencing an ongoing cost-of-living crisis, most households cannot afford to transit to heat pumps in the current market structure(s).

From @hannahritchie.substack.com "My overall takeaway is pretty consistent with the reports above: in many cases (but not all) second-hand #electric cars are now cheaper upfront than #petrol [#ICE] equivalents. At the very least, I think it’s fair to say that they're cost-competitive. I think public perception is probably the opposite: there is still a dominant narrative that electric cars are much more expensive. "

If any part of the green transition depends on the global recycling of plastics, then we might s well give up right now.... nearly half of all plastics are dumped in landfill, while less than 10% are recycled. Around 20% or more (including some of the 'mismanaged') are incinerated, no doubt adding more pollution to our degrading atmosphere.

We need a better solution to the one we are currently practicing!

If at first you don't succeed try again:

Investors in the failed British battery maker BritishVolt are trying a second bite of the cherry this time in explicit partnership with a Chinese battery maker to develop a British-based 'gigafactory'...

Whether this second try does any better is anyone's guess, but like the UK's nuclear deterrence, its unlikely anyone is going to believe this is a 'home-grown' energy player.

@thanetric @ChrisMayLA6 electric water heating is not a huge network storage problem because we can heat water when power is plentiful and then store it in the home, plus it's >250% return. Electric home heating is a bigger challenge but less of a problem than home gas burners. Home gas burners are a total nonsense, running inefficiently and poisoning the air for the residents and their neighbours. Adding hydrogen will show up more burner flaws. Boom.

@ChrisMayLA6 Back in the 70s the transition from Town Gas to Methane (initially from the North Sea) meant a huge cost in upgrading every home appliance and the pipeline infrastructure - It would have been much cheaper to crack the gas at the coast and just use the aging and dangerous infrastructure!

We need not walk away from this massive investment as we move away from fossil fuels. We can enrich our gas supply (up to 20%) with hydrogen from renewable sources using the existing distributed storage

Electric boilers in homes is a wasteful nonsense that just puts more stress on network storage.

While we are certainly seeing a shift to green energy in the UK, unfortunately because storage issues remain largely unresolved, we still contract for significant back-up capacity when normal (renewable) sources of power cannot meet peak demand.

And those 60% of those back up sources remain fossil fuel assets....

If you needed an argument why investment in network storage is required, this would be in it!

How can Africa help itself, rather than continually finding itself caught up in detrimental global economic forces?

@AnnPettifor argues (pretty persuasively) that a key element to Africa developing a self-help continental political economy would be the establishment of an African Payments Union.

She also argues this is would be a good way for African countries to manage their own green transition.
