| DONT forget the clocks go forward at 02.00hrs on Sunday morning – effectively tonight, meaning it will actually be 03.00hrs and the western world will lose an hour's sleep.
Statistics show that by observing daylight-saving time, a fall of around five per cent of energy usage means saving 300 million euros.
About 90 million euros of this corresponds with households in Spain, whose members save around six euros over the course of the summer.
However, all this has a downside, says the Spanish Sleep Society – the first few days after the clocks go forward mean constant tiredness due to the adjusting of the bodyclock, particularly those who tend to go to bed later.
Daylight-saving time was first experimented with by US-born scientist and diplomat Benjamin Franklin in the 18th century as a way of reducing candle consumption, but was not widespread until the first World War, after which it was abandoned altogether until 1974 and the first petroleum crisis.
