Jeremy Corbyn really understands what the future of the grid needs to be in an age of anthropogenic climate change.
A green energy system will look radically different to the one we have today. The past is a centralised system with a few large plants. The future is decentralised, flexible and diverse with new sources of energy large and small, from tidal to solar.
Smart technologies will optimise usage so that instead of keeping gas plants running just in case there is a lull in renewable generation the system fulfils needs by identifying the greenest, most local energy source.
There will be much more use of local, micro grids and of batteries to store and balance fluctuating renewable energy.
We will still need a grid to match energy supply with demand and import and export renewable energy abroad because the wind won’t always blow where energy is needed.
But it will be a smart grid, radically transformed.
What he is suggesting is not only practical now but also more reliable and more affordable than our present grid, according to the studies I’ve seen.
