Replace incandescent bulbs with energy saving light bulbs. Energy-saving light bulbs are undoubtedly more expensive, but their life is twice as much as any of the other bulbs available in the market.
You can save a substantial amount of energy if you avoid installing spotlights in your apartment. Spotlights are usually installed in the kitchen and the garage area, and these consume larger amounts of energy.
Switch off electrical appliances when you are not using them. For example, a good way to save energy is to turn off the computer even if it is in hibernation mode. If you need it, you can turn it on again, but there is no reason to let the computer remain switched on for several hours when no one is using it.
Appliances with standby mode features can also consume energy, so it is highly recommended that you unplug these appliances. For example, the conventional stereo on standby can use up to 8 kilowatts per month.
Among the various electrical appliances that consume large amounts of electricity, the washing machine is particularly notorious. To reduce the amount of electricity consumed by machine, always try washing the clothes below 40 degrees.
An electric heater consumes a lot of energy, so it is always better to try and choose a model equipped with a built in thermostat. This will set and maintain temperature in a room, and consequently save energy.
