The only effect on us is it makes a mess of the TV programmes- the chickens still get up at dawn, regardless of the numbers on the clocks.
In 2018 the EU ran an internet poll which resulted in 80% saying they didn't want the clocks to change at all. What remains to be decided is whether Summer or Winter time is adopted. It's been agreed that all of Europe must have the same time. The French have voted to stay on Summer time, which is my preference to get late afternoon and evening sun. Germany and Spain however have voted for Winter time, so what we will finally end up with I don't know, but in 2022 there will be no more clock changing.
There will be an environmental impact though, so it could all collapse. France estimates the energy saving from changing to Summer time saves the energy equivalent to the annual heating of 800,000 homes. Everyone is supposed to be reducing Carbon emissions, so perhaps more consideration to this time changing needs to be given?
