Changing UK voltage to 230V would see around an 8% reduction in energy used

[90% by 2030]

Just read this comment somewhere else...This can't be true though, can it? Power = current x voltage? from schooldays! - therefore lower voltage = higher current, i.e. same energy use?

"In 1988 an agreement was reached that voltage levels across Europe should be unified at 230V single phase with effect from January 1st, 1995.

The tolerance levels have become -6% to +10%, giving a single-phase voltage spread of 216 V to 253. With the possible widening of tolerance levels to +/- 10% in 2008.

As 240V fits within this tolerance level the UK power distribution networks remain supplying electricity to the home at around the 240v mark.

By reducing the actual voltage received we would see around an 8% reduction in energy used and therefore around an 8% reduction in the cost of our electricity bills"

the brits and others have long used 220 volt. it make wiring a house easier and saves power. it would be good for us to do it. all we heed to do is junk everything we have. but its a good idea,
