Working Principle Of Plug In Power Saver:
The basic aim of conserving electricity is to save energy cost. You will be surprised to know that, wasteful use of electrical energy costs us 25 to 30% of our energy bill, which could have been avoided had we taken adequate care.

Persons, who respect energy saving, do so from all angles i.e. from the building plan till purchase and use of electric appliances. It is note worthy to point out that, we can get the same benefit by proper use of the various appliances. As for an example, by reducing the frequency of opening of the refrigerator door, we can save energy. This seems to be trivial at the outset. But it is a fact. So we should be aware of the ways and means of conserving energy.
1. Washing Machine:
  • Is it top-loaded or front-loaded. (Front loaders are energy efficient)
  • Load the washing machine to full capacity whenever possible. One large load of laundry will use less energy than two small or medium loads.
  • Use after 10 PM or before 10 AM
  • Prefer natural drying over electric dryers
2. Refrigerator:
  • Do not put your refrigerator or freezer near heat vents the oven or under direct sunlight.
  • The door of the refrigerator should be tightly sealed.
  • Unplug the refrigerator and clean the dust from the back or bottom coils twice a year. Dirty coils make refrigerators consume more power.
  • Basic rule- Do not open the door too frequently and for too long.
  • Refrigerator motors and compressors generate heat, so allow enough space for continuous airflow around refrigerator. If the heat can't escape, the refrigerator's cooling system will work harder and use more energy.
3. Air conditioner:
  • Do you have ceiling insulation
  • Maintain adequate space around the outdoor unit to avoid airflow restriction through the coils.
  • Service your air-conditioners on the onset of summers. Replace filters regularly. Vacuum dirt and dust from the indoor coil to prevent restricted airflow.
  • Use ceiling or table fan as first line of defense against summer heat. Ceiling fans, for instance, cost about 30 paise an hour to operate - much less than air conditioners (Rs.10.00 per hour).
  • One will use 3 to 5 percent less energy for each degree air conditioner is set above22°C (71.5°F), so set the thermostat of room air conditioner at 25°C (77°F) to provide the most comfort at the least cost.
4. Cooking
  • Use microwave ovens as they consume 50% less energy than conventional ovens.
  • Pressure cookers are also more efficient than conventional ovens.
  • Don't open the oven door frequently. Each time it's opened, the temperature drops anywhere from 25-50 degrees.
5. Lighting
  • When possible, use natural light in place of artificial light.
  • One of the best energy-saving devices is the light switch. Turn off lights when not required.
  • As for as possible use task lighting, which focuses light where it's needed. A reading lamp, for example, lights only reading material rather than the whole room.
  • Dirty tube lights and bulbs reflect less light and can absorb 50 percent of the light; dust your tube lights and lamps regularly.
  • Ninety percent of the energy consumed by an ordinary bulb (incandescent lamp) is given off as heat rather than visible light.
  • Use electronic chokes & regulators
6. Computers
  • Turn off your home office equipment when not in use. A computer that runs 24 hours a day, for instance, uses - more power than an energy-efficient refrigerator.
  • Setting computers, monitors, and copiers to use sleep-mode when not in use helps cut energy costs by approximately 40%.
  • Battery chargers, such as those for laptops, cell phones and digital cameras, draw power whenever they are plugged in and are very inefficient. Pull the plug and save.
