在後京都議定書的時代，節能減碳的議題已持續在世界各地發酵。各國政府為達成節能減碳的承諾義務，除致力於創新技術研發，也嘗試導入需量管理制度，達到能源效率提升和政策設定減碳目標。我國行政院於2012年9月份正式核定「智慧電網總體規劃方案」，經濟部能源局復於同年10月份，在能源管理法授權下，發布「能源發展綱領」，擬由供給端、需求端和系統端三大構面，建構綠色低碳經濟體。本文選定美國作為比較法之研究主體，首先概述美國能源市場之現況與需求面管理相關重要法制政策。其次，將深入探討互通性標準所衍生之議題、消費者隱私權疑慮、安全性風險，以及如何促進消費者參與等重要法制議題，期此作為我國法制政策和綠能市場發展之重要參考。

In the post-Kyoto Protocol era, the issues concerning energy-saving and carbon reduction have becoming more and more important around the world. To maintain the international competitiveness, governments are trying different approaches to increase the energy efficiency (EE) and lower the carbon emission. One of the solutions is the "Demand-side Management" (DSM). In September, 2012, the Executive Yuan officially approved the "Smart Grid Master Plan." During the same year, under the authorization of Energy Management Law, the Bureau of Energy, Ministry of Economic Affairs (MOEA) delivered the "Energy Development Guideline." In accordance with the Guideline, the government will construct a green low-carbon economy through three dimensions - Supply (S), Demand (D), and the System. The paper selects the United States (U.S.) as the research subject for the comparative law and policy. It firstly articulates the development of the U.S. energy market. It, then, examines the relevant U.S. law and policy concerning the DSM. Next, the paper identifies several important legal issues, i.e. the issues on interoperability, privacy, security and consumer engagement. The author sincerely hopes the paper could be as a reference for Taiwanese policymakers and business in the megatrend of Energy Information and Communication Technology (EICT).
