The European Sustainable Energy Week, which starts on Monday, will take place in the context of Europe's response to high energy and electricity prices.

With all the efforts to mitigate climate changes at a global level, it might also make sense to ask how one can help to make the shift as an individual. 'Buy local, use public transport, turn off the lights' - it might sound like a naïve and repetitive marketing slogan.

But every journey starts with the first step, as the saying goes, and as long as we just stand still, we can't change anything. So -  let's turn out that light already!
