Electrical systems include all wiring throughout a building or residence and encompass everything from outlets, switches, ground fault circuit interrupters (GFCI), receptacles, and circuit breaker panels to appliances, lighting, and more.  More and more electricians are incorporating green practices and utilizing environmentally friendly and sustainable materials, systems and equipment in an effort to promote more efficient and more sustainable buildings and homes.    Green electricians will employ methods such as the use of energy efficient lighting, systems and appliances, the use of motion sensors and smart power strips, and the use of PVC free cables.  They will also be knowledgeable about renewable energy sources, including solar, wind and geothermal.  Each of these options reduces the environmental impact that conventional electricity generation has on the planet.   This section provides a listing of electricians committed to environmentally friendly services, products, and design.   Some may be LEED certified.
