The additional sunlight that late in the evening in summer is a complete waste of time especially when I am sending my kids to school in the dark in winter as a result.
the point is normaly that most (not everyone before someone chirps in) people have the heating on for an hour or so before they wwake up in the morning, then it comes on when they get home and stays on untill bedtime ish. If the heating was effectively coming on in what is mid afternoon now its got less work to do.
Your kids are already going to school in the dark (sunrise at 8:30, im presuming school starts arround then?) but they'd get an hours daylight after school to walk home in.
And there would be more time for physical excercise as everyone would have another few months of the year (ok, its wasted in summer as it makes sunset really late, but spring autumn?) where its light outside after work. So less depression, and obesity (hopefully).
I'm (almost) all for it.
