TOKYO -- Although renewable energy is attracting more investment worldwide, a significant bottleneck has emerged: inadequate power grids. One estimate suggests that solar and wind facilities capable of generating electricity equivalent to 480 nuclear reactors remain unconnected to transmission networks in the U.S. and Europe.
In Asia, the South Korean government rejected U.S. asset manager BlackRock's application to build an offshore wind farm in January, citing a lack of available grid capacity, according to local media.
