The Easter travel season is over, the summer holiday wave is still to come, which is also interesting in view of this: A young company in the Höchst Industrial Park takes a pragmatic and technically innovative approach to the fact that air travel damages the climate, it develops alternative fuel.

Meanwhile, the umbrella organization of swimming pool operators fears the uncertain future energy supply and Peter Feldmann expects difficult weeks.

The overview at the end of the day, today again with a recommendation for the weekend.

Cooler water:

Do you like to swim laps in the Atlantic in spring and in the North Sea in summer?

If so, the prospect of

weaker heated swimming pools

in the future shouldn't scare you.

Maybe it won't even come to that, but you have to think of everything these days when, with the uncertainty about the future of energy supply, familiar things are being put to the test in almost all areas of life.

For example in the bathrooms.

At least that's what the industry association Deutsche Gesellschaft für das Badewesen fears.

In a position paper, he outlines a supply scenario in which energy consumption could be regulated to such an extent that players who are not systemically important lose out in favor of industry

, including the swimming pool operators.

"It must be assumed that either energy is almost not available at all or that massive savings will have to be made over the course of this year so that the energy reserves will be sufficient in the coming winter so that there is enough energy available at least for the critical infrastructure and important commercial enterprises ", writes the association, which represents around 1,500 actors.

The pools should therefore already be saving energy so that they can refer to these savings in an emergency situation. Potential savings of up to 25 percent are possible if, for example, the water and air temperature in indoor pools are reduced by two degrees.

What do the pool operators in Frankfurt and the region say about this?

They take the issue of energy savings seriously, if only for cost reasons.

Some municipalities, such as Kronberg, are postponing the opening of the summer season, for example.

In the Taunusort, it is scheduled to start on May 14 this year, a few weeks later than usual, which means that a third of the gas that is usually consumed can be saved, they say.

What other municipalities are doing: Daniel Meuren reports and comments.

Under no circumstances, he writes, should the swimming offer be drastically restricted;

its maintenance is too important for public health.
