Snake oil?

Cue for a lot of muttering about energy used to boil kettles etc.,
but these NW electricity people aren't daft, they've done trials
showing savings to customer bills!


They surveyed customers to see if the had noticed any difference in
their electricity supply during the trials. Nothing to do with
individual customers bills.

´Nobody noticed the changes until they were given their bill and
suddenly found out theyÿd been using less electricity,¡ said Steve
Cox, the companyÿs engineering director.

From their report: projected savings in NW Electricity region = £100M
over 25 years, and approx 0.5 million customers.

Is that £8 per customer per year?

Also from their final report(s): projected savings for the whole of
Great Britain = £300M over 25 years.

There are approx 28M Electric meters (consumers) in Great Britain.

A saving of less than 50p a year per consumer?

Not sure where your numbers come from, the project reports are a bit
hard to piece together, but the wrap-up reports state possible
savings in the region of £44M in the NW, and £519 across GB (not
clear on timescales) . They also talk about average customer bills
reducing by £70 a year, which seems a lot compared to those other
figures. The savings seem partly financial in that investment could
be deferred, but savings none the less.

This trial and projections look more complex than the simple
extrapolation people are making from a one-bar electric fire, based
on elementary physics and Ohm's law. It's likely that for the
network as a whole, V = IR with R a constant doesn't apply; major
users like the railways and Google's server farms as well as
domestic appliances may well mean that efficiency varies with supply
voltage.

On the domestic front a major unknown is the take-up of electric
vehicles, with the need for many chargers.
