Scientists are using photographs taken by astronauts aboard the International Space Station (ISS) to reliably measure the amount of light pollution worldwide and to produce a global colour map of the Earth at night. The total cost of the energy consumption for streetlights is estimated by the study to be 6300 million euros/year in the European Union.
