The article in the express is more or less accurate but as Max has pointed out has nothing to do with climate change. When the Sun formed it was much much cooler than it is now, as it ages it will get hotter and hotter, we are talking hundreds of millions of years, we are not talking two or three hundred years. Why does it get hotter, basically because to maintain its volume it has to burn its fuel more quickly, in Five billion years the sun will very rapidly expand and use up its remaining fuel burning through helium and other heavier elements until the fusion by products hit Iron at which point the star is dead. The reason it expands is because of the gas law and the fact that the fusion temperature has increased dramatically for each step up the periodic table, the star ends up like an onion with layers of ever heavier elements being fused. And just for info I studied Astronomy at Glasgow University in the late 1970s and I still know a fair bit about it. I have a feeling that you are one of those that believe the earth is 6000 years old.
You want to save the planet - stop posting your online inanities! According to Mike Hazas, a researcher at Lancaster University, quoted in The Times, "streaming a two-hour high-definition film on Netflix equates to boiling over 10 kettles of water". That is more than 10 KWh of electricity. His report also claims that by 2030 Britain's internet usage would need six dedicated nuclear power stations.
I can't confirm or deny the numbers, but just for starters :- Storage Farm Server CPU Network Infrastructure at Storage Farm Network Switching through many internet routers Transmission over fibre Your ISP's infrastructure Your Router Your Network Your TV 10Kwh seems a little high but it is likely quite high, how these services make money I don't know. You can't even assume that it could save a little through multicast as you play the movie on demand with your own start and end time.
It doesn't take an hour to boil one kettle, more like 3 minutes, so it won't be 10Kwh but more like a 1/20th of that.
It does and it's a direct quote from the scientist involved as reported by The Times. What he is saying is that the amount of electricity required to view a two hour high-definition movie streamed by Netflix (or YouTube or Amazon etc) is equivalent to boiling just over 10 kettles of water, which would make about sixty cups of tea.
You're probably right, Jim, I merely quoted from the Times article and given that the scientist involved is a researcher in sustainable computing, I assumed he knows what he's on about ;. Google tells me that, on average, electric kettles are rated at between 1200 and 1800 Watts. Our current kettle, made by Krups and boils 1.5 litres in 4.5 minutes, is somewhat "thirstier" at 2400 but there are 3000 Watt kettles (and more) from Russell Hobbs, Bosch and others that are a bit faster.
i misunderstood. i read it as it would take 10 kwh for the end user to stream the HDfilm.. my laptop would melt ! i reckon my household uses about 10 kw hours a day. say-- £1-50 plus the meter charge.. no--on second thoughts--more like a £1 a day--£30 a month. all in.
That is the implication 10kwh per movie, when you add up all the power requirements of the delivery network and hardware. I reckon more like .5kwh per movie but much less than that in your own household. The article was behind a paywall so I could only see part of it.
The Specific Heat Capacity of Water at sea level is a known quantity so you can say that a Thirstier kettle, in electrical terms, will boil faster, the chances are that the maximum energy required to boil 10 average kettles will be no more than 1kwh or 1 Unit and will probably be less than that by a fair margin.
I see so you are a dictator and no one is allowed to have another point of view? If it was a game of football and Manchester United were winning, would you shoot the opposition? Alan Carlin: The weird reality of world climate policy.......
I told you the sun is getting warmer New Satellite Data Confirm Real World Temperature Cooler Than Climate Models
Currently if Manchester United were winning I would think I was in dreaming , do you not read the papers?
