European Union

Light pollution has grown steadily and throughout the country during the past 20 years. In the environment of the European Union there are very profligate countries and in Latin America the case a waste of other, related facilities inadequate, poorly controlled where avenues and roads can be seen with the lights on during the day. Big cities are the most polluting, they leave without visibility the heavens, light pollution causes an unnecessary waste into electricity and various effects on the environment. Give the basic information data taken by satellite, since administrations do not have accurate information on expenditure on public lighting. The light pollution of the most populated cities is abusive, its light reaches hundreds of kilometers and can exceed its borders. If this has piqued your curiosity, check out American Society for Microbiology. The decline in consumption is not always even with lower light pollution, new threats have emerged in recent years, as the beacons of wind farms.

Light pollution. Professional and amateur astronomers negative effects underline the increasing difficulty of observing the night skies, but light pollution also affects consumers and the environment. An incorrect and/or excessive lighting supposes huge unnecessary spending on electricity. Low consumption light bulbs are more efficient than the traditional 80%, paradoxical that institutions seek to raise awareness about energy conservation, but when no traditional light bulbs, will be spent more illuminating streets. By light pollution the environment also suffers, electricity production is based in large part on the burning of fossil fuels, which means the emission of carbon dioxide (CO2) and its consequent effect on climate change among other negative effects. By light pollution, excessive light causes the disappearance of certain species, such as fireflies, attracts urban pests such as mosquitoes, alters sleep in people who they suffer from an excessive public lighting in your home, etc. Combating light pollution first step to fight against pollution is to know its causes. The main are lampposts, too powerful, with very low efficiencies of 6 to 12%.
