You are correct to observe Denmark has high energy taxes.
Why: when you have 1) a reliable energy grid, and a 2) unreliables grid for low density energy there is a need for subsidy of the latter. This is where the high taxes go.
Denmark is maintaining two grids. When the wind is not blowing, they import expensive energy from abroad.
“LCOE” is a scam, and its author wall street Lazard admit it.
You cannot compare reliable energy with unreliable energy. Real costs include backup baseload plants, constantly turning off and on reliable baseload (turbines were not designed for this mode of operation), transmission (see first point), grid stabilization.
To your point on the main chart - the chart is the crux of the discussion. Chart shows that you cannot have high unreliables share without high taxes in mandates, subsidies, or other central planner diktat.
In other words, unreliable energy has a cost. Euros, and businesses pay for these anti-human decisions that make people poor, and Euro business.
DK is 3x US electric costs, and more so China electric cost.
