>In July, the French daily newspaper Le Monde reported that the 0.6-mile (1 kilometre) solar road was a fiasco.
>In December 2016, when the trial road was unveiled, the French Ministry of the Environment called it "unprecedented". French officials said the road, made of photovoltaic panels, would generate electricity to power streetlights in Tourouvre, a local town.
>But less than three years later, a report published by Global Construction Review says France's road dream may be over. Cracks have appeared, and in 2018, part of the road had to be demolished due to damage from wear and tear.
>Even at its peak, the road was only producing half of the expected energy, because engineers didn't take into consideration rotting leaves falling on the road.
>It was all smiles and high hopes in 2016, when the world's first solar panel road, called Wattway, opened. France spent US$5.2 million on 0.6 miles (1 kilometre) of road, and 30,000 square feet (3,000 square metres) of solar panels. It was hailed as the longest solar road in the world.
