And UHVDC transmission capacity can be rolled out faster than the volatile sustainable power capacity. The capacity to produce the equipment to produce the power has to be expected to be used over a period of time, so the volatile power harvesting equipment roll-out can't feasibly be, "in 5 years time we will have capacity equal to 150% of average power consumption". The roll out that equipment is going to be over several decades in any event.

But from first serious commitment to a cross-continental network of UHVDC it seems like "catching up" to latent demand for the sustainable power penetration of the day could well be done in five years, and from then on it woud be a matter of keeping up.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
