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.  Choosing environmentally friendly and energy efficient electrical and lighting supplies and systems can provide substantial savings in energy costs over the long term.  They also can minimize the harmful effects that traditional materials and systems have had on the environment.  Rising energy costs are reducing the payback period for capital improvements and expenditures that will not only generate future cost savings, but improve energy performance and efficiency and lead to a greener planet.  Providers listed in this section are committed to offering green electrical and lighting supplies, whenever possible.
