Falling Carbon Intensity - Can we Keep it Falling?

As this excellent graphic from Regen SW shows, we have successfully halved the carbon intensity of our electricity supply over the last 25 years.
Much of this was due to the substitution of gas for coal in the 1990's. A further, but lesser drop is due to the more recent substitution of renewables for coal, over the last five years.
But how do we keep this  rate of progress up?
It's not good enough just to say with more renewables - they are intermittent and do not occur in reliable quantity when we most need them, on cold dark winter evenings.
The answer is to shift when we use electricity, away from peak times and into times of low demand and when the sun is shining or the wind is blowing.
As a first step, you innovators and early adopters already know what to do... and to tell your friends!
