The entire rate of adoption of green technology is waiting on grid upgrades. There is something like 70GW's worth of solar for corporate buildings on a waiting list for the grid connectivity to be upgraded. The ability to transfer the power is a big problem currently. We badly need more investment in the grid capacity to speed this up because we are increasingly wasting renewable energy. Wind and Solar are both being curtailed badly by various bottlenecks which can't transfer all the production while other areas are running on gas.
