I thought this had been dealt with by the competition between Edison and Tesla, but it seems with new technology the conclusion is not so simple. Does any know the pros and cons with today's technology?
Due to the capacitative impedance, for long distance transmissions such as subsea cables, HV dc has less losses so a cable from Southern Scotland across the Irish Sea to North Wales would be dc (England to France across the channel is short enough to be ac but would require synchronisation of the National Grid with the rest of Europe).
