1.  Room Air Conditioners

01.Use ceiling or table fan as first line of defence 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).

02.You can reduce air-conditioning energy use by as much as 40 percent by shading your home's windows and walls. Plant trees and shrubs to keep the day's hottest sun off your house.

03.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.

04.Using ceiling or room fans allows you to set the thermostat higher because the air movement will cool the room.

05.A good air conditioner will cool and dehumidify a room in about 30 minutes, so use a timer and leave the unit off for some time.

06.Keep doors to air-conditioned rooms closed as often as possible.

07.Clean the air-conditioner filter every month. A dirty air filter reduces airflow and may damage the unit. Clean filters enable the unit to cool down quickly and use less energy.

08.If room air conditioner is older and needs repair, it's likely to be very inefficient. It may work out cheaper on life cycle costing to buy a new energy-efficient air conditioner.

09. Request your office, hotels to increase the AC temperature, earn social carbon credits.

2.  Refrigerators

01.Make sure that refrigerator is kept away from all sources of heat, including direct sunlight, radiators and appliances such as the oven, and cooking range. When it's dark, place a lit flashlight inside the refrigerator and close the door. If light around the door is seen, the seals need to be replaced.

02.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.

03.A full refrigerator is a fine thing, but be sure to allow adequate air circulation inside.

04.Think about what you need before opening refrigerator door. You'll reduce the amount of time the door remains open.

05.Allow hot and warm foods to cool and cover them well before putting them in refrigerator. Refrigerator will use less energy and condensation will reduced.

06.Make sure that refrigerator's rubber door seals are clean and tight. They should hold a slip of paper snugly. If paper slips out easily, replace the door seals.

07.When dust builds up on refrigerator's condenser coils, the motor works harder and uses more electricity. Clean the coils regularly to make sure that air can circulate freely.08.For manual defrost refrigerator, accumulation of ice reduces the cooling power by acting as unwanted insulation. Defrost freezer compartment regularly for a manual defrost refrigerator.

3.  Computers

01.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.

02.If your computer must be left on, turn off the monitor; this device alone uses more than half the system's energy.

03.Setting computers, monitors, and copiers to use sleep-mode when not in use helps cut energy costs by approximately 40%.

04.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.

05 Screen savers save computer screens, not energy. Start-ups and shutdowns do not use any extra energy, nor are they hard on your computer components. In fact, shutting computers down when you are finished using them actually reduces system wear - and saves energy

4.  Microwave Ovens & Electric Kettles

01.Microwaves save energy by reducing cooking times. In fact, one can save up to 50 percent on your cooking energy costs by using a microwave oven instead of a regular oven, especially for small quantities of food.

02.Remember, microwaves cook food from the outside edge toward the centre of the dish, so if you're cooking more than one item, place larger and thicker items on the outside.

03.Use an electric kettle to heat water. It's more energy efficient than using an electric cook top element.

04.When buying a new electric kettle, choose one that has an automatic shut-off button and a heat-resistant handle.

05.It takes more energy to heat a dirty kettle. Regularly clean your electric kettle by combining boiling water and vinegar to remove mineral deposits.

06.Don't overfill the kettle for just one drink. Heat only the amount of water you need.


  1. I usually keep my thermostat at 68 degrees F during most of winter which saves me a great deal of money on my energy bills. If you're feeling cold, put on extra layers of clothing to keep warm or buy an electric blanket. During the summer I put my blinds down as well and also use fans on some days instead of the air conditioner. I also wash my clothes in cold water instead of hot water. It's little steps like these that can help reduce the overall consumption of North American Power and therefore help save us all money in the long-run.

  2. Energie besparen, de noodzaak:

    De potentie van zonne-energie is enorm. Als de mensheid er in slaagt om slechts een fractie van de dagelijkse hoeveelheid zonne-energie die op onze aardbol valt effectief en efficiënt om te zetten in elektriciteit of warmte, dan zijn economie en ecologie daar enorm mee geholpen. Geen wonder dat er massaal wordt ingezet op de ontwikkeling van nieuwe technologie en dat veel energie en geld wordt geïnvesteerd in het verhogen van productiviteit en rentabiliteit van technische oplossingen onder andere in zonnepanelen om energie besparen te realisren. De doorbraak klopt aan onze maatschappelijke deur. Wie zorgt er uiteindelijk voor de doorbraak? Wanneer precies? Met welke technologie? Deze en andere vragen blijven naar verwachting nog wel even onbeantwoord. Omdat een grootschalige doorbraak van vele factoren, mensen en middelen afhankelijk is. Zonne-energie is enorm in beweging en dit overzicht is slechts een momentopname. De fysieke potentie van zonne-energie (vallend op de continenten) is 1800 maal de hoeveelheid primaire wereldwijde energie consumptie van 2007. Dat is ruim 9 maal meer dan de eerstvolgende duurzame technologie: wind.
    Om de capaciteit van alle bestaande kolencentrales in de wereld te vervangen, is 1800 maal de hoeveelheid zonne-energie nodig (in geproduceerde kWh) die in 2010 wereldwijd wordt geproduceerd. FirstSolar (USA) is met 10% van de wereldproductie de grootste PVproducent. Suntech Power (China) is nummer twee met 7%. In 2007 nam China het stokje over van Japan als grootste producent van zonnepanelen. Kleinere producenten zullen naar verwachting de komende jaren onder druk komen te staan. De top tien producenten (waarvan een flink aantal in Duitsland zijn gevestigd) zijn nu samen al goed voor 47% van de totale productie en dit aandeel zal volgens Roland Berger stijgen tot 60%. Deze gevestigde orde heeft al 80% van hun productie ondergebracht in Azië, waar de productiekosten gemiddeld 50% lager zijn. Deutsche Bank schat dat rond 2008 de feed-in tarieven de drijvende kracht zijn geweest achter 75% van de wereldwijde PV-installaties. Inclusief het nieuwe feed-in van het Verenigd Koninkrijk in 2010, hanteren op dit moment 75 landen een feed-in beleid. In Nederland worden subsidies op zonnestroom betaald uit algemene middelen. In het nieuwe regeerakkoord van september 2010 wordt een feed-in tarief aangekondigd, gebaseerd op een opslag op grijze stroom. Energie besparen maakt Nederland leefbaarder.
