I'd say it's slowly happening. There was a large drop in 2019[0] by around 25% (~50TWh) from 2018, ignoring the 2020 drop (around 25% ~33TWh compared to 2019) due to the pandemic, 2021 was almost back to 2019 levels (-3.5%) and 2022 was an increase by ~6.5% compared to 2019. Looking at quaterly data[1] it looks like 2023 will be well below 2019 again. And no, it hasn't been replaced by gas[2], although there's no clear trend in gas for electricity, if anything gas consumption is down due to the war.
