From an engineering perspective, I struggle to see that this will actualy do anything at all.

Motors are already VERY efficient pieces of electrical equipment. The market push to larger motors and consequently higher power consumption has been down to getting more suck and machines which are wider so cover a larger area quicker.

If you were to impose a max consumed power figure then given that the consumer expects a certain level of cleaning (i.e. suck) that would require a smaller area of suction which means it would take longer of vaccum a set area resulting in pretty much the same level of power consumption and it would take longer for us to all vaccum our houses!

Indeed. I'd like to see how they back up their claim that "the energy efficiency of vacuum cleaners has dropped over the years".

This is clearly policy based on someone (with no engineering background) wandering round Comet reading all the labels bragging about huge motors and deciding they are going to change the world. It's truly frightening that such obviously flawed policy even goes public without review by someone who actually has some knowledge in the subject matter. Makes me wonder what policy they'll pull out of their @rse next.

Meanwhile, my Sky set top box (and everybody else's - how many have they sold, I wonder?) consumes 20W, whether it's on standby or not, 24 hours a day, 7 days a week.

Let's compress that in to an hour a week of cleaning (optimistic in our household ), and we find it's equivalent to a 3.3 kW vacuum cleaner.

I was amazed by how much electricity is imported from both france and the nederlands during peak periods, nearly a third of the UK's energy

If enough people complain to their MEP, I bet they will brush it under the carpet.

....And if nobody complains to their MEP, there will be a clean sweep when it comes to voting on it.

Lol, is it buggery, the links dont have the capacity to deliver that much.

Many moons ago I did some work on the cross channel DC-DC link which runs under the channel from Sellindge in Kent to Les Mandarins near Calais.

There are two other links which are:

UK-Netherlands - 1.3 GW
UK-Northern Ireland - 500MW

Now the Northern Ireland one is almost always exporting power so cna be seen as a load on the UK system

So if you then look at the remaining max import of 2.8GW.

The Uk demand today (whcih will be lowish due to the weather) was 38GW so we are talking about 7% import.

In reality today, the power delivered by the two DC links was about 1.4GW so far from max and Ireland were supplying (rare) 250MW.

For demand info, have a look here:

If you look at the spreadsheets you will note that demand in winter periods is upto close on 60GW.

The pumping column is energy consumed re-filling the top ponds on the pump storage stations including those at Dinowig and Ffestiniog

An even better page here, Mark. Scroll halfway down to the generation by fuel type table and it shows the amount taken from the interconnectors:

Isnt wind generation a joke, 3.4GW of capacity and we might be lucky to get 500MW today.......about the same as a single big generator at a coal/nuclear station (of which most have 4-6!)

If only they fitted one in Jimbob's smalls...  ...renewables sorted

It would need to be coated in some pretty special paint though!

Lord knows how a protracted high-pressure winter cold-snap would be tackled with planned reliance on renewables (esp. wind-gen.) :-/

Totally unfeasible, it would seem:

And note this gem: "Earlier this year, six wind farms were paid £900,000 to stop generating for one night, because the system became overloaded."

For those who wish to form their own opinion based on source material, here http:// http://ec.europa.eu/energy/efficiency/studies/doc/ecodesign/eup_lot17_final_report_issue_1.pdfis a link to the working group's report (dated 2009). Some indication of those who worked on the project can be found in the list of attenders at the stakeholder meeting at A13.

There are lots of tech graphs in s6.

There's also a working paper from 2010 http://ec.europa.eu/energy/efficiency/...06.../text_for_cf_25_june_vcs_v0.doc

Lol, as somebody how project manages EC funded projects, I am pretty used to documents like that which are full of inferences.

Sadly, a scientist desires the eutopia that is perfection where as an engineer compromises on reality.......I note that paper is written by a scientist (whos main currency is papers and cash from the EC....)
