Reply to comment by cmdr_awesome in The European Union to nearly double the share of renewables in the 27-nation bloc's energy consumption by 2030 amid efforts to become carbon neutral and ditch Russian fossil fuels. by chrisdh79
We hit ~60% solar and windpower in Denmark in 2022 because Kriegers Flak came online. I think we are above 75% with biomass and garbage CHP.
It's always a rude awakening when you look at gross energy consumption though. Renewable share drops a lot when we include transportation, heating etc.

Denmark is still well above the average, even for Europe.

It's scary when we look at the primary energy issue, compared with the renewable portion.
The good news is that it isn't as bad as it looks as that primary energy also includes the energy that goes to waste in creating it. All that waste heat leaving engines and smokestacks is a high portion of that primary energy.

Sure, but you really need to get the electricity generation to a certain level of Low CO2 production before the electrification of other industries. It's a multiplier. Just like electricity generation, the economics of switching these other industries has recently (or currently is) at the tipping point, where it makes financial (or Security) sense to switch.
People will be surprised how fast these other industries transform. Jut like they are today with electricity generation

Primary energy is mostly waste heat. Using it massively overstates its importance. Electrification usually cuts energy use by 1/2 to 2/3. Once you allow for that, you find we're much closer to net zero than you would expect.
