8% of electricity, not total world energy.

But the growth rate has been huge for as long as records have been kept, and was a factor of just over 10x between 2014 and 2024, speeding up more recently.

PV and wind together are likely to start breaking the electricity market severely in the first half of the 2030s; I hope, but it's not certain yet, that ongoing battery expansion will allow the demand for electricity to increase and this can continue to the end of the 2030s, because at the current pace of development those scale up to all our energy needs, not merely our present electrical needs, in a bit less than 20 years from now. (PV alone would do all of it in 20 years at present rate of change).
