When I escaped Fukushima after the accident and went down to the Kansai area they were burning energy like nothing had ever happened.

Since Kansai runs on 60Hz, they have no way to send up electricity our way without some infrastructure being built. So even if they tried to save electricity, it would have no impact whatsoever on the situation here. Of course they could try and save power for the good of saving.

It is unfair to exclude the 23 wards.

How is it unfair? Because it affects your house? This is all about keeping the city running as smooth as possible, it's not a popularity contest. It makes total sense to blackout a mostly residential sector than a commercial sector, as the commercial sector will affect EVERYONE.

Try imagine if they shut down Shinjuku-ku between 6pm and 10pm on a weekday.

It's really easy,

Change all lights to LED lighting would save 50 to 80% on the lighting needs. The most common tubes would go from 40W to 18W while the lightbulbs would go from using 60W to 6-7W. Also, because of the lack of heat emitted by LED lights, it would be possible to set the AC 1-2 degree lowers without it feeling any warmer.
