It may look like a power station with a golf course on it, but it's actually the world's cleanest waste-to-energy power plant with a ski slope on it. OGN featured Copenhagen's Amager Bakke last year in Hedonistic Sustainability, and this new photo shows the landscaping around the winding green ski slope has bedded in, so the whole sloping side of the power station looks like a bright green hillock. Starting at a height of 90m, the 400m long slope makes a 180 degree turn as it twists down to ground level - to the lift back to the top.
EV battery swapping service: Batteries are the single most expensive component in electric vehicles.
