Save energy, money and the night time environment
Too much of anything is waste.
Light that goes into the sky without consideration wastes energy and money.
The International Dark-Sky Association estimates about 30 percent of outdoor lighting is wasted due to unshielded or misused lighting. In countries like Australia, outdoor lighting makes up around 20% of the daily energy usage. This means approximately 6% of our energy generated daily is wasted. When we couple this with the ecological and astronomical impacts of light pollution, it becomes even more important that we make good decisions around outdoor lighting.
Environmentally responsible lighting brings energy efficiency and conservation as well as improved safety. Understanding good lighting principles is easy and something that everyone can do- from the lights that illuminate our cities to the fitting on your front porch, every decision can make a difference.
