According to the linked page, K1 = 10^16 W = 10,000 TW. We are at ~20 TW = 0.002 K1.
0.01 K1 was a generous overestimate. Strictly speaking, K1 really should be 2e17 W, putting us at .0001 K1.
(600 exajoules/y = 600,000,000 Tj/y, divided by 31.5M s/y = 19 TW. https://www.statista.com/statistics/265598/consumption-of-primary-energy-worldwide/ https://www.statista.com/statistics/265598/consumption-of-pr... )
