The Eiffel Tower, Paris’ most famous icon, is going green. Earlier this year an American company installed two vertical axis wind turbines at a height of 120 metres, spinning above the second level. Both turbines generate around 10 000kWh a year, enough to power the restaurants and shops of the tower. The monument is already equipped with LED lightning and all toilets run on rainwater. According to UGE’s Gromadzki, who led the installation, “The project happened because the mayor’s office wanted it to happen. They really wanted to make a strong statement about renewable energy”. This is not a surprise, since Paris will host the much anticipated climate summit at the end of the year. Many people see this as a turning point in climate negotiations.
