That's a given, however even in absolute terms, over the next 20 years that dynamic will change, if renewables continue along their current growth path. I won't be surprised to see an internationally adopted scheme setup within 5 years, that sees countries penalised for not meeting clean energy targets. Whilst Climate Change continues to be an issue of great global concern and of sufficient priority, we can expect renewables growth rates to be strong and thus that basis being so, the significance of their absolute contribution over time will be more fully realised.

To what extent do you think it will change?

It will change to the extent to which it is valued, in accordance with the growing demand for clean energy, in respect of the degree to which addressing Climate Change remains a serious concern and global priority, by which the growth path of renewables will be influenced.

Very profound. Supply and demand. Who would've guessed it.
At what point, if any, do you think that clean energy growth pa will outstrip growth in fossil thermal pa?
You mentioned a term of 20 years in reference to changing dynamics? How do you think growth rates, in absolute terms, will compare in 20 years time? What's your feeling? In what way do you think it will be different?

It's incredibly speculative as to what the future holds, especially in times of great uncertainty about environment and climate and how that is likely to impact our economies and government policies.

Fine.
You state with certainty "over the next 20 years that dynamic will change" but you're not even prepared to speculate on how it will change?
Maybe real growth for renewables will fall even further behind fossils.
That would be a change too.
Maybe it won't and that would be no change.
But, if you don't know.....

Not at all. Blind Freddy can see based on current growth rates for renewables, where they are heading if the trends continue, however the future is not guaranteed with absolute certainty. That applies to anything in this world. Government policy in the face of Climate Change and its priority, will dictate what happens.

If the current trends continue, growth in renewable energy contribution will continue to fall further behind fossils in absolute terms.

No it wont. Quite the opposite.

Growth rate related to installed capacity for renewables has been increasing for 30 years or more.
But, in absolute terms, it's contribution is still growing at an order of magnitude slower than that of fossils. If that current trend continues, it's contribution WILL continue fall further behind fossils.
