Futuris Episode 4 (2009): "Energy Efficiency"

A quarter of the total energy used in Europe is for lighting purposes. Current research efforts are focusing on new technology with the potential to halve European lighting costs. Dresden's City Museum is saving energy by controlling their more than a thousand fluorescent tubes and halogen spots through a computer network. This set-up allows the intensity of each light to be individually changed, depending on the natural light conditions, and allows for the programming of various lighting modes. The museum is just one example of the "smart lighting" systems that are becoming common practise around the world. However a much larger potential to improve energy efficiency exists in updating the light sources themselves.
