Year-round British summer time would not reduce energy bills | Energy bills

Professor Aoife Foley says that by keeping British Summer Time all year round, less heating and lighting would be needed (Save energy by not turning back the clocks in October, expert says, 19 October). Alas, the amount of daylight is not changed by tinkering with clocks.

Most of England and Wales gets just eight hours of daylight in December and January, while Scotland barely gets seven hours. If BST were kept during these months, the sun would not rise until almost 10am in Scotland, northern England and Northern Ireland. Homes, schools and businesses should keep their lights on until mid-morning. We already tried the BST experiment all year long – 50 years ago. He was dropped after three years.

In winter, we are on standard time for our part of the planet, corresponding to natural time, when the sun is at its highest at noon and at its lowest at 24:00. It is in summer that, since the law of 1916, we are on summer time, by calling 7 am “8”, 11 am “12” etc.

Rather than twisting the clocks, it would be better to adapt to the seasons by opening schools and businesses at times that suit them. This too could be a simple change: one hour earlier in the summer.
