I, the undersigned, have noticed that the electricity bill for our residence shows great variations depending on the presence or absence of one single member of this family for any given billing cycle.
Since this family member shares a double room with his spouse, there should not, logically, be any significant variation in electricity consumption.
On close observation over long periods of time, it was found that this particular family member is challenged by electrical switches. They can, if the occasion warrants, be switched to the 'ON' position. It is, however, virtually impossible for them to be switched 'OFF'.
Since no strategy has proved successful so far, technology is the last resort.
I request you to install sensors in my residence, which will automatically switch off lights and fans and appliances such as electric water heaters when they are not in use. Bathroom lights and exhaust fans are a particular source of wastage of electricity. Once these sensors are installed, as a positive spin-off, energy wasted in nagging will also be saved.
Automatic off-switches for taps are also required. Closing taps properly is also a challenge for this particular family member, and we ought to save every drop of water that we can.
Hoping for a successful and speedy installation,
Your hopefully energy and water saving,
