Britain and India introduced a plan on Tuesday to improve connections between the world's electricity power grids to accelerate the transition to greener energy.
Linking the grids would allow parts of the world with excess renewable power to send it to areas with deficits. For instance, countries where the sun has set could draw power from others still able to generate solar electricity.
The "Green Grids Initiative" at the COP26 climate talks in Glasgow, Scotland, was backed by more than 80 countries and could set a model for how rich countries help poorer ones to reduce their emissions and meet the goal of capping global warming at 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial norms.
