Cancel British Summer time – GMT always

2 Comments 4th February 2016

The UK should be permanently on GMT.  We should not move to BST at any time.

Why does this matter?

There are many reasons, in no particular order, to stay permanently on GMT:

1   energy saving – the only 2 recent studies using empirical data have suggested that there is no benefit or even a disbenefit to being on Daylight Saving Time:

One of the few research studies into the actual effect of extended DST (http://escholarship.org/uc/item/3d8252zp), in Australia during the Olympic Games in 2000, concluded:

In this paper we question the findings of prior DST studies, which often rely on simulation models and extrapolation rather than empirical evidence. By contrast, our research exploits a quasiexperiment, in which parts of Australia extended DST by two months to facilitate the Sydney Olympic Games in 2000. Using detailed panel data on half-hourly electricity consumption, prices, and weather conditions, we show that the extension failed to reduce electricity demand. We further examine prior DST studies and find that the most sophisticated simulation model available in the literature significantly overstates electricity savings when it is applied to the Australian data. These results suggest that current plans and proposals to extend DST will fail to conserve energy.

In the US research ) was carried out in Indiana after the trial 2 month extension of DST in 2007 started.  It concluded:

Our main finding is that—contrary to the policy’s intent—DST increases residential electricity demand. Estimates of the overall increase are approximately 1 percent, but we find that the effect is not constant throughout the DST period. DST causes the greatest increase in electricity consumption in the fall, when estimates range between 2 and 4 percent. These findings are consistent with simulation results that point to a tradeoff between reducing demand for lighting and increasing demand for heating and cooling. We estimate a cost of increased electricity bills to Indiana households of $9 million per year. We also estimate social costs of increased pollution emissions that range from $1.7 to $5.5 million per year. Finally, we argue that the effect is likely to be even stronger in other regions of the United States.

 

The California Energy Commission mentions this research and there have not been any other studies done on actual usage after DST changes since the mid-70s.  The patterns and types of electricity usage have changed considerably since.

 

So in fact the research indicates that we should stay permanently on GMT if we wish to reduce our energy bill.

2   Historic – noon is when the sun is at its highest.  BST ruins this.

3  People change their pattern of life according to BST and so doubling BST or cancelling GMT would only lead people to change their lives and go back to their ‘bad’ old ways.

4  BST penalises northern people (I am not) and those who get up early.

We should to adapt ourselves to our environment and not try to force the environment to adapt to us.

    Very good idea.
    The whole point of having a measure of time is to provide a constant reference, so it is crazy to undermine that by fiddling with the clocks. And the notion that such fiddling can somehow save daylight is an insult to our intelligence.

  2. David Hughes says:

    no, abandon greenwich mean time for good and to allowing a lot more better use of the daylight hours.
    the fact is we should be on greenwich mean time plus two hours all the time it would make a very big differences to lighter winter afternoons let greenwich mean time be history.
