South Korea aims to build the world's first nationwide smart grid system to reduce its emissions by monitoring energy use more carefully.
Unlike conventional "dumb" electricity grids, smart grids allow two-way communication between electricity suppliers and consumers, as well as enabling more dispersed generation and storage of power.
The grid, to be set up by 2030, is part of the country's $103bn initiative to increase its generation of green energy from the current 2.4 per cent of total power to 11 per cent in the next two decades. According to a government-led committee, South Korea could lower its greenhouse gas emissions by 40 million tonnes annually with a national smart grid.
