"I have drastically reduced the amount of time I spend in the shower, but I am a poor example. As a minister, I earn a salary that others can only dream of. Plus, I come home late, get up at 6 a.m., and am out of the house again by 7. With such a schedule, it's not necessary to heat in winter. For people working from home, retirees with small pensions, and families, it is a different story.
"My counterpart from the Netherlands recently told me proudly that they had launched a campaign intended to cut the average showering time from 10 minutes to five. I had to laugh. I have never showered for five minutes in my life. I shower quickly," he said.
