Sure @matwin  - Mars and I can probably fit in writing a manual on domestic power consumption in our copious amount of spare time. 🤔 

Fortunately we both have understanding wives who go out to work, make loads of money, and cook us lavish meals whilst we play-around at home writing blogs.

More seriously, I do make comments on appliance efficiency throughout the forum as and when I can.
Here's an illustrated description on dedicated LED lighting, for example.

My time is currently divided between:

• renovating a cold NE room to become a home-office
• writing briefings to elected Councillors about future energy strategy, and threats to grid security

It's a very tricky balancing act...

... and becoming the more urgent since the Iberian grid outage of 28th April

@matwin I do enjoy writing, but not sure I could stretch this into a book 🤣 But it could make for a very interesting article. We have wine fridge that's horrifically energy hungry so it's been off for years... would you like to write a piece for the main site @transparent?

@editor maybe we can start a topic for everyone to chip in what they know about wasteful kWh consumption?

@transparent And in addition to all the above @transparent , from the photos you have published, I believe you are busy running a child slavery cartel… 😉

@editor Classification of consumption might be based on watching an old style electricity meter - you know, how fast that disc is revolving. Low consumption devices might come in the category of ‘leisurely’, medium consumption category might be known as ‘breezy’ and those high consumption devices would be categorised as ‘spinning top’. 

My spinning top devices such as the ASHP and DHW system will have to continue as is, the tumble dryer is at least a heat pump equipped device but the oven is rarely used as this role has been taken over by the air fryer! Regards, Toodles the Scrooge!

not sure I could stretch this into a book

I think my trouble is that I could easily write a whole manual on the efficiency of home appliances.

Yes, I do take great care in selecting which appliances to buy in the first place,
and I also take into account the 'standby-current' for when a TV or a monitor is idle.

But my home now exists in a state of energy abundance, brought about by 56kWh of storage battery.

That changes the mindset more than you might imagine.
It's like living in a Net Zero world which had been achieved through applying sound scientific judgement rather than political policy!

My computers are rarely turned off.
They have integral DC-DC Converters and can operate from a supply anywhere between 20v - 60v DC.
Almost all have AMD or ARM processors because they draw very little power when sleeping.

Turning electronics off-on creates thermal stresses which slightly reduces the equipment lifetime.
I've now reached the point where the long-term reliability is more valuable than the 'free' electricity which gets used.

I build my own LED lighting fixtures, some of which are integrated into the fabric of the building...
Here, for example, I'm placing LED-strip into an aluminium channel which forms the corner-bead of a plastered wall.

Of course, most people could never achieve these outcomes.

But that's how I get the insights as to how things should be done.

Hi. David here , living in Inverness area for last 34 yrs. Mechanical engineer. I've been working in renewables for 20 years, started in wave energy for 10 yrs then switched to heat pumps, field servicing, repairs, advice ,installation. Now working for a charity who, alongside local councils, have been upgrading scotland's housing stock for Net Zero and area based schemes for the last 35 years.

I have had various heat pumps in various property types, currently nibe 1155 gshp rad system with a 400m loop. No solar yet , our useage is pretty low so i'm not in a rush.

Cheers! 🙂

Welcome, @dgt_73. By the sound of it, there's quite a bit going on here that might interest you and certainly you've plenty of experience we'd love you to share.

Are there any pending personal projects you're getting geared up for?

I am a UK based product manager for an energy storage systems company with an interest in traditional PV technology and sustainable clean energy. I will do my best to provide advice and references.
