Arriving in Freiburg by train, you might notice the solar panelled towers of the station building. These solar panels are everywhere; on the football stadium, hotels, the conference centre, and even a factory. With 1,800 hours of sunshine per year, solar power is the main source of energy in Freiburg, making it one of the most ecologically friendly cities in the world. In fact, some say that Freiburg generates nearly as much solar power as the whole of the UK.
In Freiburg it all began in the 1970s, when local people were strongly against plans for a nuclear power station nearby. The historic centre has been car-free since 1973, with over 400 km of cycle paths! However, it is the modern residential districts on the outskirts which most interest environmentalists. In the area called Rieselfeld, residents live in small blocks of south-facing flats called ‘passive houses’. The design of these houses keeps them warm or cool, without needing central heating or air conditioning at all. The houses cost around 10% more to build, but over many years they cut energy bills and energy loss by 90%. Vauban is another quiet area, with solar panels everywhere and a large number of passive houses. It’s a safe, clean area. It’s busy, but with people and bicycles instead of vehicles. Officially, only one person in four has a car and it costs around 18,000 euros a year to keep one outside town, in a 'solar- garage'.
In Freiburg, being green is part of the economy, and local people buy shares in different green projects, for example the solar football stadium. Not surprisingly, this remarkable eco-city has won many awards and other German cities are now competing to become more eco-friendly. So why aren't more countries around the world doing the same?
