According to Luxurylaunches, the 110-metre vessel uses an estimated 7.2 megawatt-hours of electricity per day to keep its systems running, enough to power around 250 American homes. Why the Kaos superyacht consumes so much electricityOperating more like a luxury hotel than a private vessel, Kaos houses 31 guests and 45 permanent crew. But Kaos’s energy consumption raises questions at a time when Spain and the EU are urging residents to conserve power while energy bills continue to rise.
