It is light that is shining in the wrong direction. Instead of shining onto the ground where it is needed it shines up into the sky. It is wasted energy. It is wasted money. It causes increased air and water pollution. It robs us of the majesty of the Night Sky. Slide 3: The Earth from Space at Night Slide 4: Europe & the Mid-East at Night Slide 5: East Asia Japan Indonesia & Australia Slide 6: The United States at Night Slide 7: Wisconsin At Night Light Pollution Facts : Light Pollution Facts Every Year the US wastes more than $4 Billion lighting up the Night Sky. Wisconsin wastes 125 MW each hour lighting up the Night Sky. This is almost a quarter of the capacity of the proposed power line. Light Pollution creates air and water pollution, including mercury pollution. Poor Lighting kills millions of birds each year and affects the habitats of many other species. Light pollution affects human health and has been linked to breast cancer. More Facts : More Facts Typical lighting on a single billboard requires the burning of 7 TONS of coal per year. This creates 23 Tons of carbon dioxide, a greenhouse gas. 356 lbs. of sulfur dioxide which creates acid rain. 215 lbs. Of nitrogen oxide which creates smog. about .03 gram of mercury. As little as .001 parts per million of mercury can cause health problems. More Facts : More Facts A 55 watt Low Pressure Sodium light puts out as much light as a 115 watt High Pressure Sodium light or a 175 watt Mercury Vapor light. Light Pollution Negatively Affects Animals : Light Pollution Negatively Affects Animals Millions of birds die each year from collisions with brightly lit buildings and towers. The light confuses them and interferes with their migration. Poor lighting near oceans interferes with newly hatched sea turtles from finding the sea. Poor lighting eliminates habitat for deer, loons, eagles, and other animals. Studies have shown that light pollution affects humans by interfering with circadian rhythms causing grogginess, impaired thinking, depression, and has been linked with some cancers, especially breast cancer. Lighting Definitions : Lighting Definitions Poor Lighting is defined as lighting that allows light to either shine upwards and/or shine off to the sides which causes glare. This also wastes energy. Good lighting prevents light from going upwards or off to the side and only puts light on the ground where you need it. It is also more energy efficient. Slide 13: Bad Lighting Slide 14: Good Lighting Slide 15: Light Trespass Light trespass is when the light from someone else’s property shines onto your property. Slide 16: Some Solutions Hubble Skycap For NEMA Lights The Culprit The Solution Before and After Slide 17: Some Solutions Things to do to ReduceLight Pollution : Things to do to ReduceLight Pollution Use Energy Efficient Lighting Sources like Low Pressure Sodium. Use only enough light to get the job done. Use fully shielded light fixtures that put the light on the ground where you need it and not into the sky. Use motion sensing lights. Talk to your local, state, and federal politicians about reducing light pollution by enacting lighting legislation. You do not have the permission to view this presentation.
