Very effective communications tool.

Scores would need validation (SAP) (NHER) and caveat that indication only, all home differ in size/rooms/build etc

Would need redesin of market, price transparency and quality guarantees. Could work but !

Interesting concept. Current take up and interest in free services is low, awareness capaign needed. For a segment of aspiring households in Kensington etc but for low income segment it would not work. Needs to be 100% independent and with certificates etc real cost would be higher, my estimate £50 per home for max 2 hours, thus party bit impractical across 2 homes?

Segmented for Kensington, maybe. Newham doubtful. Difficult unless 100% independent. Cost nearer £50 per home, moving to two home maybe not a party
Cost ?
Poor ?

This is something that is going to be introduced with all suppliers. I know the concept is to provide a central source of information regarding all energy use however, I can't see the various suppliers providing information through to one source? Local Authorities have struggled to get the data on a borough wide basis as it has previously been regarded as 'commercially sensitive'

Like this one as it gives the owner the ability to make informed choices for investment based on the various possibilities. EST web site provides some of this info' but in a different format. This is more 'user friendly'

we don't all live in London! what about the proles in the outer reaches?

We need some way of visualising/understanding what CO2 savings mean. Red busses and how savings could power them is one good way of doing this. Tonnes of C or CO2 have little relevance to consumers

Keep it simple otherwise only fanatics are likely to use the system. Points are better to unsderstand than savings, linking points to red busses would be good.

I think this is an excellent idea. If we are to get maximum benefit from investment in home generation, we do need to share resources, and trading with each other seems a very good way of doing this. So long, of course, as the trading is fair and safe.
The concept seems to work best for electricity, rather than the more nebulous energy. I do not expect to have gas I can sell, but I can have electricity from PV and wind turbines, even from my CHP boiler.
Such trading is best done quite locally - it is basically small scale - so a possible name is Neighbourhood Electricity Trading Scheme - NETS.

Global Action Plan is already running something very similar through its 'EcoTeams' programme. See www.globalactionplan.org.uk

this is a stronger concept but is still to complex. consumers are interested in price reduction not co2 reduction.

This is already being done through lots of Community Action energy initiatives, and the presentation is usually FREE from an Energy Efficiency Advice Centre. Hundreds of talks like this are being given each year NOW.

The display in the film is excessive and confusing.

Why not just fit every plug socket with a small display, showing the number of watts that device is using. I already bought a similar device to this (from Maplin), except you have to plug it in, and plug the device into the back of it. It's given me a very good understanding of which devices use what, and which devices are still greedy on standby.

This is an excellent idea. The UK is very slowly moving towards it with electricity disclosure on bills and the piloting of more informative bills. See work by the CSE in Bristol and the ECI at Oxford on both these: the people they asked were keen on annual energy reports as well as better bills.

The displays look great, and the evidence is that displays like this do help people learn how to conserve energy. In addition to selling them, they could be loaned from public libraries/information centres.

Apart from what such a scheme might produce in terms of electricity, it's good from the point of view of getting lots of us to connect up our thinking about supply and demand. Householders generating their own electricity also need accurate information on insulation, and how best to control their heating and hot water systems. ie use new methods of supply in tandem with reducing demand.

This is information all users should have and might wake up those who don't think much about the energy they consume.
In multi occupancy households e.g. with children or students, it would be great for each person to understand their consumption and by using icons similar to those illustrated here it will be easy to understand.

in its purest and naive form i love this idea. I would be a great way for communities to generate their own power. the potential problems i can see arising is who would own the power generated, who would foot the bill of instilation, and this doesn't take into account renters, olny home owners.

I think this is a great idea and (as they say) Every Home Should Have One. How about making it part of the Building Regulations for all new builds and re-wiring jobs?

didn't get any image so not certain about this one!

Great idea - for Londoners. Bring it out into the rest of the country too, pleaes!

How does this gadget collect data about individual appliances, lights, etc.? You're surely not suggesting that the whole house is equipped with self-identifying, self-monitoring appliances?
It IS possible to monitor electrical consumption at the meter by 'consumption signatures' (see NIALMS on web) but that does NOT work at the level of individual lightbulbs.

re: other comments: The statement isn't just about fuel mix disclosure, it is about comparing yourself with benchmarks of usage, CO2 and cost, as shown in the other sheets. a great idea, as long as estimates are not used for any of the data!

Interesting but too many options will detract from the object of reducing energy. Need to show when energy is above normal. Small point - the display shows energy used as watts; watts are power (energy/second) so should be shown as Watt-hours, kWh or Joules.
