Gas & Electricity

[Bill Walker]

If an element is more efficient, where does the wasted electrical energy in the inefficient element go?

There is no wasted electrical energy, only electrical energy saved, not used. (You bill will be less)

You alluded to the first law of thermodynamics.



When making energy more efficient we really need to look at the 2nd law of Thermodynamics. And how heat always transfers to cold, efficiency is gained by slowing down that transference. This is why it's a great idea to heavily insulate you home, to retain the heat your energy (heating system) has produced. (Unless you want to heat the street :))

If we want a bigger difference between Q and W (above) we need to slow down the DeltaU.

Put simply, we can use less energy with the same results through technology. Boris is correct about the new eco kettles.

Fuck me. Equations and shit to prove Boris was right that we can save £10 a year by buying a new kettle, save for the fact the kettle will probably be £30 anyway. It won’t touch the sides.

The problem with this is that kettles are used to boil water and be used immediately. Having a better insulated kettle will stop the water cooling down as quickly if it isn’t used straight after it boils. Most people boil a kettle to use the water while it’s boiling rather than to store it and use it later.
All an eco kettle does is better control the amount of water boiled, so that less is routinely wasted. Carefully measuring the water you need in a normal kettle would have the same effect.

My bill has just gone up from 340 a month to 630 a month, I genuinely don't know what I'm gonna do, I'm just in shock, it's double my mortgage

Get onto a smart meter and pay for what you use, everyone around me has gone from ££200 to £400 or more, our gas and electric in august was £87. That’s a 3 bed semi, but just the two of us and a dog.

I check it everyday, todays cost us £2.24 (we both work from home mostly). We’re with Utility Warehouse

No offence mate but that irrelevant in the scheme of things

Can we just clarify that whatever Johnson said today, right or wrong, he is still a ****?

Wasn't me who brought up the Law of Thermodynamics mate. But I do love all that shit.
Boris didn't have this idea, it isn't him who is right (or wrong) it's his advisors, I don't think Boris has a fucking clue.

 

[denislawsbackheel]

Is the right answer

Yes I know. Sometimes it happens on here.

Not having a go at you my friend but the whole cutting down on things or being more sensible is great, we should all be doing that anyway however it doesn’t matter. Standing charges remain so even if you use fuck all it’s costing you. If you sit in the dark, in the cold, in silence. It’s costing you. Saving £10 a year with a new kettle that will cost you £30/40 anyway. Just shows how out of touch these cunts are.
