The BIGGEST problem with clean energy

Tom Scott released a video in the last few days showing similar problems in the Orkney Islands.  With all the different tech being tested, there's far more supply than demand most of the time, and the interconnect to the main grid is nowhere near robust enough to export all of it.  Nobody wants to upgrade the interconnect unless they can be guaranteed to increase the amount of energy produced, but nobody will commit without the upgrade being done 🤦‍♂️🤦‍♂️🤦‍♂️
