Energy efficiency implementation is an industry comprising firms which retrofit or replace inefficient equipment with more efficient parts or equipment, with the goal of reducing energy consumption. Energy efficiency implementation firms have the resources, both physical and intellectual, that can provide advice and materials to entities/facilities, assisting in decreasing energy use. Energy efficiency implementation is performed in two distinct ways: by retrofitting existing equipment or by replacing existing equipment completely. Retrofitting enhances existing equipment by making it expend less energy. The goal of this kind of implementation is to save kilowatts (kW) and kilowatt hours (kWh). The difference between these two measurements is that one is a power rating (kW) and the other is a measurement of energy actually consumed (kWh). ==Utilities == Public Utility Commissions in many states mandate that their utilities design and implement energy efficiency programs. The funding for these can be reflected in their rates or are collected through a surcharge in monthly customer bills. Some utilities design their own programs and implement them using a rebate form or other application, and administer the programs using their own staff. Most major utilities hire implementation contractors who are responsible for the design and implementation, and some implement programs already designed and approved by their PUC. Some programs require a co-pay by the customer, some are installed at no-cost. Utilities invest in energy efficiency for the following reasons: # Social interests: environmental issues and resource conservation # Economic interests: to prevent costly construction of power plants or the purchase of more energy The end result is that utility companies have more energy to sell, or in other words, they are able to sell their excess capacity to more customers in the area without increasing their production capacity. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Energy efficiency implementation」の詳細全文を読む スポンサード リンク
