I would call this a basic misrepresentation, but you just pulled that number out of thin air. Or somewhere worse?
50% of the decline is from industry, 50% from residential[1]. During that timeframe, industrial output increased.

All of think links here, the person you are responding to, mine (above) and your own directly point towards reduction in industrial use.
Just a thought.
This government data is must more substantial than that link, and it puts the ratio at 70% reduction in electricity due to deindustrialization.
Moreover - the OP's comment was a blatant misrepresentation (lie) - by ignoring deindustrialization, the primary factor as stated in the article (and in reality) - plus a bit of a thrown slander aka the 'Telegaph-esque' nonsense.
This is not Twitter.
This is not even controversial.

The linked numbers are not per-capita, they are absolute.
