Having a job and high salary is not good enough reason to stop trying on saving your electricity. If you can spend your life comfortably with less electricity bill, then you should do it right? You can start by insulating the geyser and the water pipes. Set geyser thermostat to 60 degrees as this is more than an adequate temperature for shower or a bath. A shower uses much less (hot) water than a bath. Switch-off appliances when not in use.
A proper lighting is very important. Even when you want to save the electricity, it doesn’t mean you need to force yourself living in a dark and gloomy house. You should consider using energy-saving bulbs instead of normal incandescent bulbs. They are not just save more than 20 percent of your electricity, but also last about 12 times longer than their counterparts. When you leave the room, turn the lights off.
