This is a network of power. This time not economic power, but megawatts of capacity.
The pink nodes are power plants producing energy. They are the sources in this flow network. The green nodes are sinks. They are the utilities in the All Country World Index (MSCI ACWI) and are scaled by the MW of power reaching them directly or via the network of subsidiaries (blue nodes).
The right hand side of the figure reveals the piping in the network, where the nodes are removed and only the weighted and directed ownership links are shown.
This is an example of climate finance, a topic slowly appearing on the radars of institutions. See, for instance, Mark Carney's speech, as Governor of the Bank of England.
