Climate Change

Oh gosh, wholesale gas prices went up in your graph at the exact time of the invasion of Ukraine

thank for admitting I am correct

by the way Ellal, here is some information to help with your lack of knowledge:

"Alex Staker, Head of Commercial Operations at Bionic, explains why these price drops aren't always passed on to customers: "It's to do with the way energy is bought and sold and the risk associated with this process. To be able to offer fixed rates, energy suppliers need to buy power in advance of selling it to customers. This means the rates at which they have bought wholesale energy to sell today might differ from the current wholesale rates.

"Suppliers also need to factor risk into their price calculations, in much the same way as finance providers factor risk into the prices they charge for credit.

"Energy suppliers are continuously buying energy to make sure there's enough to cover demand. If demand exceeds supply then they need to buy more at current market prices to cover the shortfall. But if supply exceeds demand, then suppliers need to sell the excess energy back to the grid - if the day-ahead price is lower than the price they bought the energy for, then they'll lose money.

"When the market is so volatile, the risk to suppliers is greater and so prices go up. And this is also part of the reason why it can take time and a consistent run of lower rates for any price drops to be passed on to customers."

 
Do we need an explanation, apart from corporate greed? ;)

Oil giant BP has 'more cash than we know what to do with' after almost £10bn profits​

BP boss Bernard Looney, who has splashed out on a £5.2million apartment, is set for a bumper bonus. Yet the company rejected calls for a windfall tax on oil and gas producers to help ease the cost of living crisis​

 
We know that the base temp of our water supply in the winter is way down as compared to the summer my 9.5KW shower can struggle in the middle of winter - so all that energy trying to warm up very cold water.
So how about this for an idea. All new or refurbished mains water infrastructure/ supply has to be buried much deeper and so will benefit from ground heat.
Would that work or is the depth already giving the max benefit. Or is the flow or pipe bore too much for it to work :unsure:
 
No, won't work. The flow rate is too high for the surface area of the pipes and the length of pipe means you don't have enough harvestable energy available.

Think of it as a GSHP. If we went 8-20m down we'd see roughly 10 degrees C (average UK air temp). Beyond that it goes up by something like 3 degrees per 100m for a while. So best case you've got 10 degrees water.


But that assumes that you have enough surface area to extract that heat, which you don't, the volume of a pipe quadruples if you double the radius/ surface area, and that the ground surrounding it can replenish that heat indefinitely, but it cant. In undersized GSHP s the loop temperature can drop because you extract more heat from the soil around the loop than it gets from below or above.

Also, digging down 8m isn't trivial. It isn't going to be economical.

Economical- I thought we were talking about an extentientual threat to the human race, the world is burning. Or is it that the government makes a lot of dosh charging vat on domestic fuel bills

I'll rephrase:

It would be insanely expensive and give you virtually no benefit at all. Spending the same money on Solar thermal panels or PV to heat the water would be much better value even in winter.
 
I saw a report a few days ago, where an entire herd of reindeer died. 2000 of them.

The cause: the melting permafrost where they roamed had allowed a anthrax-infected carcass to become exposed, after thousands of years "in the freezer".
Ancient anthrax is wot killed 'em.

Further on, scientists reported viable viruses and bacteria that had been frozen for almost 50000 yrs, stuff that we have zero immunity to.
