節電は永遠のテーマです。 Electricity saving is an eternal theme.

Almost all the land line telephones being used now are so called multi-functional phones and consume electricity all the time. 
In general households, the average time of the land line telephone use may be 10 minutes a day. If so, the telephones are wasting electricity for 23 hours and 50 minutes a day. 
This wasted electricity can be saved by SOD (Switch On demand) I developed more than 20 years ago.
