electricity saving LED Lamp Promoting greater energy efficiency

Energy conservation¹ is the practice of decreasing the quantity of energy used. It may be achieved through , in which case energy use is decreased while achieving a similar outcome, or by reduced consumption of energy services. Energy conservation may result in increase of , value, , , and . Individuals and organizations that are direct of energy may want to conserve energy in order to reduce energy costs and promote economic security. Industrial and commercial users may want to increase efficiency and thus maximize profit.

The commercial sector consists of retail stores, offices (business and government), restaurants, schools and other workplaces. Energy in this sector has the same basic end uses as the residential sector, in slightly different proportions. Lighting plays a large role at 25% of the total energy usage. Lighting is also generally the most wasteful component of commercial use. A number of case studies indicate that more efficient lighting and elimination of can reduce lighting energy by approximately fifty percent in many commercial buildings.

Commercial buildings can greatly increase energy efficiency by thoughtful design, with today's building stock being very poor examples of the potential of systematic (not expensive) energy efficient design (Steffy, 1997). Commercial buildings often have professional management, allowing centralized control and coordination of energy conservation efforts. As a result, (about four times as efficient as incandescent) is the standard for most commercial space, although it may produce certain adverse health effects.
