Daylight savings coming tomorrow
It’s difficult to think of it in that terms – if you’re an office worker (and I do count those students and teachers as being in that boat), it just feels like a stolen hour of sleep.
This was not the original purpose. In 1784, Benjamin Franklin propose aligning “working time” with “available day light” to conserve power – at the time coming from candles and fires.
In our times, of course, the bang is much bigger thanks to the use of solar power harvested from the sun. We make efforts in that direction too. Timing our cooking time with peak solar generation makes heating food a zero cost item. Seriously, waiting until 1pm instead makes life a lot cheaper.
Of course, the whole country is in this position with 13.5GW produced by solar farms and private arrays. Many of these feed into the grid, so any power not consummed by the solar panel owners can be enjoyed by the whole nation. Which means during office hours, much of our energy is zero extra cost – the only cost is from installation.
If you take this to the next level, during the summer, we should cook at midday and not in the evening. This was a pattern my parents used during the 1970s and 1980s when I was living at home. Lunch was cooked, Evening meal was cold.
If we’re talking about decarbonising our diet, maybe something to consider…
