TO TRANSFORM THE ENERGY POLICY PARADIGM BY INNOVATING THE CONSUMPTION STRUCTURE environmentally-friendly Energy efficiency is the most and economical energy source. As such, enhancing energy efficiency fundamentally reduces energy demand, thereby improving the environment and alleviating the burden of adding to base loads. The first and foremost task of the Third Energy Master Plan is to innovate the energy consumption structure by improving energy efficiency. The Korean government is set to reduce energy consumption by 18.6% below the BAU level by 2040 in order to decrease energy imports and contribute to a stable energy supply system. To this end, the government will improve demand management by sector, including industry, buildings and transportation, and facilitate the demand management market. Energy efficiency will be improved in a comprehensive manner. Specifically, energy intensity targets will be managed by sector, including industry, buildings and transportation, while high-efficiency devices and products will be distributed and energy use will be optimized at the system and community levels. Businesses with high energy intensity will be encouraged to pursue voluntary agreements to reduce energy consumption as well as increase their use of high-efficiency devices. A Building Energy Management System (BEMS) will be widely introduced to reduce energy consumption in buildings. In the transportation sector, efforts will be made to improve fuel efficiency, distribute eco-friendly vehicles and innovate traffic systems.
