Valencia is considered one of the most enlightened cities in the world. For the more religious, it can be interpreted as a sign from God. But, the 300 experts in health and environment meeting in the city of Valencia, speak of light pollution.
Each resident of Valencia consumes 137 kilowatts/hour per year. For those who do make do with the energy units, this amount is double the spending of Madrid or Barcelona.
However, the data may get worse. Experts of the Spanish Astronomical Society claim that the light consumed by Valencia is four times the statistics of the German or Dutch.
“Artificial street lighting should be designed to provide us with a safe walking the streets, but not to turn night into day,” explained Jaime Zamorano, expert from the University Complutense of Madrid .
“A decoupling does not make much sense.” In addition to pollution and energy waste, astronomers refer to the economic cost to the government. As the population grows at a faster rate below 1% annually, the area illuminated at night that makes it to 5%.
