Things to Do to Increase Energy Efficiency

The term ‘energy efficiency’ is widely used these days. Labels on devices, advertisements from energy companies, and even promises from governments use this phrase, but what does it really mean? In this article, we touched on energy efficiency.

What is energy efficiency?

Energy efficiency means using less energy to deliver the same level of energy.

Making homes, vehicles and businesses more energy efficient; It is a whole of efficiency-enhancing measures such as preventing energy losses in gas, steam, heat, air and electricity, recovery and utilization of various wastes, or reducing energy demand without reducing production with advanced technology.

So how can energy be used more efficiently? How can energy efficiency be increased? Let’s look at it in terms of substances. When these substances are applied, all kinds of energy can be used cheaper and more efficiently.

How to increase energy efficiency?

  1. Put an aluminum foil covered insulation board between the wall and the radiator. You can prepare these panels yourself at home by covering the styrofoam plate with aluminum foil.
  2. Thermostatic radiator valves, which adjust the radiator temperature, provide 15-20% energy savings per year. Do not cover the radiators with long curtains. Do not put furniture. Do not obstruct the hot air flow.
  3. In winter, keep the north-facing window curtains and shutters, if any, closed. If possible, use thick curtains to the north.
    Insulate your kettle and hot water pipes to prevent heat losses.
  4. Replace your heating boiler or room heater with condensing, high efficiency ones.
  5. When the temperature is high in the houses heated by the central system, reduce the temperature with thermostatic valves instead of opening the windows. You can reduce the energy consumption by 6% by reducing the ambient temperature by 1 degree. Do not increase the ambient temperature more than necessary in winter.
  6. It is appropriate to heat living rooms between 19 and 21 degrees and bedrooms at 16-18 degrees.
  7. Keep apartment entrance doors closed. Double doors or automatic closing aid in heat preservation.
  8. Turn down your heater and open your curtains on sunny winter days. Take advantage of sunlight as much as possible.
  9. Prevent leaks by checking door and window gaps. Use window insulation tapes for this.
  10. Use insulated glass, although it is more expensive than standard glass. They provide comfort and energy savings. If 12 mm double glazing is used, the heat loss from the glass decreases by 50%. Using low-e glasses will further reduce heat losses.

  1. Insulate your building. Up to 30% energy saving is achieved with insulated walls.
  2. When buying a house, make sure that it is an energy-friendly house. You pay more initially; but you will save both money and energy for a lifetime.
  3. Take advantage of natural daylight. Arrange your furniture in a way that makes it easier for daylight to come in. Paint your walls a light color.
  4. If you can, try solar panels for heating and electricity generation.
  5. Lower the luminance levels. Don’t turn on your lights without need. Instead of ceiling lighting, choose regional lighting that is smaller and illuminates the work area.
  6. Use LED lamps and compact fluorescent lamps. They provide energy savings compared to an incandescent lamp and have a long life. Replace the light bulbs of the whole house with energy efficient models.
  7. Keep your lamps clean; dirty, dusty lamps consume 25% more energy.
  8. Use a water-efficient shower head.
  9. When you are done with your devices, unplug the device. Do not leave the devices in standby mode.
  10. Unplug your mobile phone charger, just plug it in when you charge your phones.

  1. Operate your air conditioner at temperature and fan speed appropriate for the season.
  2. Use multiple sockets with an on-off button. So you can turn off all devices with one touch.
  3. Enable energy management features on your computer and monitor. Use energy-efficient.
  4. When purchasing home appliances you will use, compare not only in terms of price but also in terms of energy savings. Although the investment cost for a device with high energy efficiency is higher, the energy savings that the device will provide during its 10–15-year life cycle will save you the money you paid. While purchasing a device, remember that the ones marked “A” and “A +” are the most efficient. There is an energy consumption difference of over 60% between high-efficiency and very low-efficiency devices.
  5. Turn off your electrical devices such as DVD player, radio, television, computer, etc. when you are not using them. Unplug your modem when you sleep at night.
  6. Use your electrical devices in accordance with the instructions written in the user manuals and in suitable environments. Proper use will reduce the energy consumption of the device and increase its life.
  7. Place your fridge in the coldest part of the kitchen, away from the stove and radiator. Thus, your refrigerator consumes 15% less energy. A 10 cm space should be left around the cabinet for sufficient air movement. Consumption will increase 2-3 times as long as the air circulating around the cabinet does not cool.
  8. It is necessary to keep the refrigerator at +5 degrees and the freezer at -18 degrees. Lower values ​​mean energy wastage.
  9. Put the food to be put in the fridge after cooling down to room temperature. Hot food causes more energy consumption.
  10. Refrigerator and freezer doors must be airtight. To check the tightness, squeeze a clean paper between the gaskets and close the cover. If you can easily pull out the paper with the lid closed, the refrigerator is taking in air.

  1. Defrost the food taken out of the freezer a little bit in the fridge first. Thus, your fridge consumes less energy as you will help to cool down.
  2. Close tightly the juicy foods you put in the fridge. Due to the containers left open, the humidity rate in the cabinet increases and the cabinet consumes more energy to absorb this moisture.
  3. Do not open the refrigerator door frequently. You cause more energy consumption.
  4. In fan ovens, the cooking time and the temperature required for cooking are reduced since the heated air will constantly circulate in the oven. On average, 20% less energy is consumed. (Cooking time 10-15 minutes, heating 2-3 minutes)
  5. Choose your cooking appliance according to the size of the ingredients you will cook. Do not bake a toast in an oven.
  6. The size of the flame under the hob should not exceed the size of the pan. If you put a small saucepan on a large fire, you will waste energy.
  7. Use pots and pans with flat bottom. Pots with six curves consume 50% more energy.
  8. Use high conductivity material. If you use glass or ceramic pots in the oven, you will get better results than metal pans. You can cook at temperatures 15 degrees lower than others in glass and ceramic pots. Glass and ceramic containers retain heat longer than metal containers.
  9. Pots and pans with contaminated bottom absorb heat, reducing cooking efficiency. Keep the bottom of your cookware clean and shiny.
  10. While cooking in the oven, if you open the oven door before the cooking time is over, you will lose 20% energy.

  1. it does not accelerate, it only causes energy loss.
  2. With the pressure cooker, you can cook your meals in a shorter time with less energy consumption.
  3. Cooking on the stove is more economical than cooking in the oven.
  4. While brewing tea, boil as much water in your teapot for how many tea you are preparing.
  5. Do not preheat the oven if it is not absolutely necessary.
  6. When purchasing, choose the washing machine capacity within the range you usually use. For example, even if the newly released 10 kg capacity machines are Class A, they are not suitable for small families of a few people and families who need frequent laundry.
  7. Always run your washing machine at full capacity. But don’t force him to work beyond his capacity. If you put a small amount of laundry in your machine, choose the program that will ensure that it takes in less water.
  8. Pre-soak heavily soiled and stained laundry. In this case, you leave less work to the washing machine and clean your clothes with one wash.
  9. Do not put more detergent and excessively foaming detergent in your washing machine than recommended in the manual. Choose detergents that you can wash at low temperatures.
  10. Laundry dryers are devices with high energy consumption. Dry your laundry by hanging.

  1. Irons are among the devices with the highest energy consumption capacity in homes. Ironing capacities have reached up to 2200 W. If you unplug before you’re done while using the iron, you can use the available heat for a while.
  2. Iron your laundry while it is damp.
  3. Approximately 1/3 of the road covered in vehicle use is for going to and from the workplace. As much as possible, going to and from the workplace together with the people you work with will reduce both your fuel and vehicle costs.
  4. Choose public transportation vehicles such as trains, subways, buses, ferries and so on instead of your private vehicle during your travels. Travel short distances with your bike or on foot.
  5. Stop your engine in long waits.
    In order to minimize the fuel consumption and the amount of pollutants discharged from the exhaust, the vehicle speed should be between 35 and
  6. 95 km / h in urban areas. When the vehicle is driven at 115 km / h instead of 95 km / h, 15% more fuel is consumed.
  7. Do not use the engine at high revs and use a gear appropriate for the engine speed. Do not suddenly accelerate while taking off, driving and shifting gears.
  8. As the mileage of the vehicle increases and its age increases, the amount of fuel it will consume and the amount of pollutants it will release from the exhaust increases. The same model zero year old vehicle throws 30% more pollutants and consumes more fuel than a 5 year old vehicle.
  9. Keep your vehicle windows closed or open enough to allow air exchange while on the road. This will save you significant fuel.
  10. Use the fuel recommended by the manufacturer in your vehicle. Do not overfill your fuel tank. This will cause fuel leaks and evaporation losses.

  1. Use the appropriate engine oil for the season in your vehicle and remember that the oil filter must also be changed when changing the engine oil.
  2. This is important for both fuel economy and engine life.
  3. Have your vehicle periodic maintenance and adjustments done on time. If not properly maintained, almost all of the mechanical systems in your vehicle increase fuel consumption.
  4. Make your vehicle’s exhaust gas measurements periodically.
  5. Clean or replace the engine air filter periodically.
  6. Tire is an important function in the fuel efficiency of the vehicle, and it affects the fuel consumption between 5–10%. Make sure that the tire pressure of your vehicle is at the recommended setting in the user manual. Insufficiently inflated tires will increase your fuel consumption.
  7. Use radial tires. These tires save fuel and have a longer life in the city and especially on the highway.
  8. Replace fluorescent and mercury vapor lamps with high pressure sodium lamps in process lighting.
  9. Adjust the air conditioning units in the sections where less people enter and exit in enterprises working at night. Turn it off if possible.
  10. When not needed, fans, ovens, motors, etc. close.
  11. Make sure that the compressor air inlets are from cooler rather than hot equipment rooms. Yield improvements and paybacks are interesting.

  1. Careful control of the excess air coefficient, the heart of the combustion air, provides significant energy savings.
  2. Huge savings can be achieved with the operating tariff structure and power factor improvement.
  3. Significant savings can be achieved by insulating process lines and tanks.
  4. Using energy efficient motors pays for itself in a short time, especially when new applications are in question.
  5. If the pressures are overdesigned, decompression will not heat the process and there are huge savings.
  6. It is possible to use the heat dissipated by air or water cooling in large compressors, especially in winter space heating, with a suitable design.
  7. Economizers ensure optimum use of outside air. The savings achieved with their use are enormous.
  8. The payback of radiant heaters used for partial heating instead of heating entire areas is interesting.
  9. Spot ventilation reduces the amount of conditioned air required. The savings are huge.
  10. Make it your goal to instill energy efficiency awareness in employees and to adopt a management approach knitted with efficiency philosophy.
