The Dutch are sitting on the largest gas field in Europe, and was for years and years a net energy exporter because of it. It was capped for "environmental reasons", including a few tremors that shook some buildings.
Wouldn't you know it, re-opening it is part of the "emergency energy policy". It'll take good bit of time to fire it all back up, but the gas is there.
If Ole Poot would have run the invasion with any kind of military acumen, there would not have been time to organize, dust off emergency plans, reopen coal plants and open up shuttered gas fields. Time is not on his side.
