Quite a surprise awaited a lot of tourists as 35 tons of wood was dumped at Louvre square. It happened to be a crisp sunny day when the wood delivery man came, and just for fun I checked what the production of my solar photovoltaic panels was. The 2,100 watts the panels were producing was far more than I was using at the moment so my electricity meter was spinning backward (in a figurative sense since the meter is digital).
