That’s true. Maybe they’re thinking ahead to a time when we might have
to
accept a change in lifestyle rather than trying to find “sustainable�
ways
to maintain our current ones.

Even full lockdowns only led to a 7% reduction in CO2 so the sustainability
part is little to do with personal transport and a lot to do with home power

and manufacturing it would seem.

I’m not sure there’s a sequitur there, but what the heck.

Whats the problem? Less people have been travelling during the lockdown hence
the reduction in admissions. Any increases in home power usage has been
offset by the reduction in office power usage so where does the other 93%
of emissions come from? Answer, normal home power usage regardless of lockdown
freight transport, manufacturing, construction and agriculture.

So that particular, relatively minor change of lifestyle isn’t going to
have the necessary effect to make the world sustainable. It’s therefore,
by definition, not the kind of change I was referring to. I don’t know
what is, yet.

No doubt you think energy companies need your advice as well:

If energy companies don't understand basic physics thats not my problem.
But then most of them believe they can send "green" electrons down the pipe
simply by you signing up with them so go figure.

Is everyone here really so dumb a to think that green electricity
generation and the national grid ought to work by making sure that green
electrons travel from the generator to your home? What was that about
basic physics?

As discussed earlier, AC only makes electrons move a short distance.
The supplier simply makes a one-off transfer of green electrons to fill
the house, where they continue to oscillate indefinitely. Installation
takes place by adding a small DC bias to the supply on a sunny and windy
day with low demand, when the grid has plenty of spare green electrons.

I suggest you have another go at reading what I wrote.

OK, thanks, got it now.

I wasn’t referring directly to you, but to a general feeling in some of the
postings, too diffuse to respond to individually.

Its too late to back pedal now. Your "What was that about basic physics?"
comment was aimed directly at me because either you misunderstood what I was
saying or didn't even bother to read it.

Anglia have liveried trains for the Bittern line, East Suffolk line
etc, but I've only ever seen them on the wrong lines!

Odd you should mention that... this morning one of the Fen Line GN
trains was liveried "Gatwick Express". Which more different to the plain
livery than the straying GA Stansted Express ones (which are at least
the correct side of the river).

Apparently six GatEx 387s have been loaned to GN as temporary 365
replacements.

They are having shuffle, then, because we've not seen 365s on the Fen
line for a couple of years.

Continuing the theme, this afternoon they put a 700/717 (I was too far
away to tell) on an Electrostar diagram from Kings Cross to Ely.

The former, surely?

According to my electriconics lecturer mumblety-plus years ago, all
electrons are green anyway:

He explained valve theory as little green ball-bearings bouncing from
Cathode to Anode, an image that has stuck with me ever since.
