Hpc Risks Using Up The Entire Uk's Power Supply By 2035 May Be Rationed

Recommended Posts

Britain may be forced to ration the internet, expert warns, as web use could consume 100% of nation's power supply by 2035

Britain could be forced to introduce internet rationing, after an expert warned it could consume the country’s entire power supply within 20 years.

Experts said we were close to “filling up” the nation’s network of optical fibres for the first time ever, with the demands of popular video-streaming websites like YouTube and Netflix putting an unprecedented strain on communications infrastructure.

HPC to cause the UK's infrastructure to collapse.

What is this rubbish? It's in the Telegraph too.

It starts by saying that the internet uses too much electricity then conflates it with a data bandwidth bottleneck.

Did a 5-year-old write this?

Bandwidth does not flow along wires for free, it requires some electricity.

They have looked at the growth in internet traffic, converted that into energy requirements and plotted it into the future.

A bit like the way Estate Agents predict house prices.

To be fair, by 2035, the UK's super-Green power grid will struggle to keep one PC running.

...or an excuse for ISP's to hike prices.

from the link in 1st post

“If we don’t fix this then in 10 years’ time the internet could have to cost more.”

all the more reason to decentralise the power supply and the communications hubs.

1)go solar, wind

2)have a look at mr musks powerwall thingy for backup power storage

3)buy a nice little low TDP HTPC and hook it up to a mesh network..with a smallish antenna capable of 2-3km range....independent of your main connection.

(you can get cheap and cheerful quad core intel mobo with integrated cpu for about £70...TDP is only around 25w all in...4w for cpu and about 20w for the rest)

just call it (postcode.number)@ ECS.mesh.net( basically piggybacked wi-fi for emergency communications services )

won't do streaming vids but good enough to send important emails about welfare etc to nearest and dearest in SHTF scenario.

and if mad mullahs try to take out ISP server, no problem.

because it's not going through ISP server, it's going through mesh...which will calculate the permutation of wi-fi paths available and then ride through all of them to get to the destination in question.

This is being seriously discussed in the industry, some of the google server farms already use as much power as a small city and the net currently uses around 10% of Japans power. The basic science is that the energy used per bit transmitted is declining polynomially, whilst the number of bits per second being transmitted is growing exponentially. A new technology, silicon photonics, aims to miniturise telecomms technology on to a chip and bring an exponentially reducing power per bit (in line with moore's law)

so these ideas are out there and may prove a limit to the internet.

In principle, the perfect digital switch consumes no power. Digital electronics is, however, analogue in reality and consumes power as it switches between two states. As speed is paramount, electronic digital circuits are always operated on this cusp, where the circuits can be switched just fast enough to meet circuit clocking speeds. As a result, digital processotrs consume a lot of power.

Naive academic completely fails to see that either the market will provide more innovative technological solutions, or the price will rise to reflect demand.

Instead he propose statist solutions to a problem that doesn't really exist.

yeah, but, it used to take a gallon of petrol to visit all my friends to get them to like the picture of my toenails.

in other words, the WASTE in these places is what causes the energy usage.

It's a pity the heat can't be captured for use.

Is it possible to design a building that could cool itself???

Just relocate all data centres to Greenland :D

If you can extract the heat then it can be used to warm offices and homes.

In winter it can be used to heat the personnel offices of the centre itself.

Summer's the problem. Maybe using it to heat water somehow would be better as everyone uses hot water and it stores energy relatively well.

It depends.

Many new data centres have a "PUE" of less than 1.1. PUE is the ratio of total energy consumption (cooling, ventilation, lighting, security + servers/networking) to IT energy consumption (servers/networking).

Older data centre designs may have had PUE of 2.0-2.5 (i.e. cooling and ventilation used more than servers) - but these are rapidly getting upgraded as the energy costs make them uncompetitive in today's market.

Total rubbish. Each household (not counting industry) in the UK uses about 500 Watts, on average. I really don't believe that the feed to a single household would ever involve in excess of 500 Watts of server and routing power. How many bits can a household consume?

The telecomms system, through which all the routing is done, is powered by batteries FFS!

I think they mean data centres

The increase in traffic is not just down to domestic usage or to people watching Netflix etc. There are absolutely massive Data Warehouses out there collecting all sorts of stuff from both the internet or being transmitted across it from other computer systems. This corporate and state data gathering on its customers and citizens has increased exponentially recently. The quantity of various computer logs alone being stored and processed are enormous. For example the British state no longer sends all its traffic over the government's data network. Much of it is encrypted and competes for bandwidth on the public networks with all the other domestic and commercial traffic. Networks tend to be as fast as their slowest components and there are lots of crappy, old, slow, unreliable bits of kit (switches, cables etc) scattered over the UKs public IT infrastructure.
