Maybe they could unplug any electronics that are not being used, make sure all lights are turned off, get solar panels?
The easiest way to reduce the electricity bill is that we must not waste it.There must be some rules to be followed in house when you leave the house.
All the electrical appliances should be turned off before leaving the house.
The electrical appliances should be 3 or 4 starred appliances so as to save electricity. They can also use solar panel to save electricity.
The lights must be turned off during the day time and sunlight should be used during day time to do work.
All the efforts will reduce the electricity bill.
