Energy Efficiency and Environmental Issues

Lighting affects the environment in a number of ways, including energy usage, the materials used to produce lighting products, and light's impact on the nighttime sky. For example, energy-efficient lighting demands less electricity, which reduces polluting power plant emissions. Some materials used in lamps, such as mercury, are toxic to the environment and must be handled carefully. Light shining into the sky causes light pollution.

The LRC is working to reduce lighting energy use, toxic materials, and light pollution.
