Paper has become a worse and worse business since electronic media has taken over gradually. But the "turn factories off" was a bit of a joke. Though Nordpool does have its spikes and it indeed makes sense to sometimes turn off factories. Depends on your process.

So in a sense the old industries are gone, from lack of demand, and new industries have gone where there is cheap power available.
