Earlier this week, the world’s longest sub-sea power cable entered service. International linkups between power grids are key to the world’s renewable future, as they present an antidote to intermittency. If it’s windy in Britain, surplus power can find its way to Norway. On still days to the south, Norway’s hydropower can supply British homes and businesses.
Though the United Kingdom is forging ahead with wind power and continues to issue large-scale permits for the development of both on- and off-shore facilities, it is still a way behind its northern neighbour when it comes to overall renewable-energy capacity. Recent energy-price spikes have shown just how dependent the country is on gas to provide baseline power. Contrast this with Norway, where fully 98% of the grid transmits renewable power, and additional baseline security comes from links primarily with Sweden, but also northern continental Europe.
