Did you follow all the energy saving tips out there only to find out, that the power consumed by your so called energy efficient appliances is still too high?
In that case, the culprit responsible for the high power consumption, could be one or more of the not very energy efficient appliances in your house. But be careful! Before running off and buying that new tumble dryer, you should consider whether the purchase of new equipment is really going to pay off.
Is my domestic appliance energy efficient? Is it worth purchasing a new one?
If you are unsure whether your device requires too much power, it is best to compare the power consumption of that household appliance with data of other similar ones currently available on the market. Shops both online and offline always clearly state how much power the device they are selling uses.
To find out how much power your own appliance consumes look for a label stating the wattage. This is often located near the cord or under the device itself. If there is no label you can also contact the manufacturer or take look on their webpage.
Based on the information you get, calculate the costs of the consumption and try to see if a possible savings justifies a new purchase. Please note that when you make the calculation, your usage habits play a major role in the correctness of the results. For example if you watch TV only one hour in the evening, the savings from buying an energy efficient TV would not be so great. On the other hand the situation in a household where the TV is running all day is different. Therefore it is important to set up the calculations according to your habits.
For washing machines, the savings may be less than first anticipated. Suppose you wash 4 times a week using a washing machine in energy category b with a consumption of about 1.54 kWh per wash. With a new washing machine of the class a + + +, which consumes 0.93 kWh per wash, you would save about $39.68 a year. This at an electricity price of $0.31 per kWh.
If your old washing machine breaks down and you are looking for a larger, quieter one with more technical options then it is also worth looking at the power consumption. However, one should consider whether it would make sense to replace a fully functioning washing machine by an expensive new device, only to make an electricity saving of $39
Clothes dryers can cause a very high electricity consumption. The newer energy efficient appliances are considerably more economical because of the modern technology packed into them. With an efficient dryer you could save a lot of energy and therefore also money. The differences in consumption are enormous in these types of devices.
In the electronic stores the dryers standing side by side can have a power consumption varying as much as 3 kWh per drying program. Those who pick the wrong device here will be paying for it every time they use it for years to come, and this totally unnecessarily. At 3 kWh, the additional costs will be 0.94 dollars per drying cycle. At 220 washing cycles and subsequent use of the dryer, the extras alone would amount up to $206,8 per year.
Refrigerators and freezers
Unlike electrical appliances, which are used only for a certain time, refrigerators and freezers are continuously in use. With this type of equipment costs can be saved regardless of individual usage habits.
The savings made by replacing an inefficient refrigerator or freezer vary on the difference of the new one with the previous model. But the change will almost certainly pay itself off within a couple of years. Anyone who owns a power hungry refrigerator should look into this problem exchange it. In fact it is the old refrigerator or freezer, together with an inefficient dryer and bad residential lighting that are the top avoidable energy consumers in our homes. The faster these power hogs are turned off, the better.
The power consumption of a computer depends very much on your own usage habits. There are many people who use their oversized superfast computers only for simple tasks like checking the mail or browsing the internet. If you actually don’t play graphic intensive 3d games or render your own gigantic videos the only thing that multicore processor and ultra cool graphic card is going to do is stand there and consume electricity to no use. It’s like driving a drag racecar to the supermarket everyday and then wonder why you need to spend so much on gas.
Think in advance of what tasks are going to be performed on the computer by you or your family members, then select the required hardware components according to that criteria. With the right energy efficient composition you can save a lot of energy in the long run.
Just as they are more humble in prestanda a laptop computer is more humble in electrical consumage as well. A laptop can consume as little as 25% of the electricity required by a stationary one. If the electrical bill is on your mind a laptop is therefore very much recommended.
In addition to buying a complete pc, there is also the possibility of putting together your own. This way you can chose your hardware components and exclude the power consuming ones you might not need. Don’t feel like screwing the thing together yourself? There are several shops that for a small fee will assemble a computer based on components of your own choosing.
Home lighting is a large part of the cake in our total energy costs. Unlike many electrical appliances, the cost of upgrading to energy efficient light bulbs is relatively low in relation to the potential savings. However, the investment in high-intensity LED lamps with high lumen number is still expensive in contrast to compact fluorescent lamps (CLFs).
Energy saving lamps with the luminosity of a 100-watt light bulb uses about 20 watts. LED lamps are more efficient, however there are currently only a few models that can replace a 100 watt incandescent bulb. With a consumption of 11 watts, a led lamp could at a daily usage of 4 hours, save $40 a year. A 20-watt energy-saving bulb, which replaces a 100-watt bulb, could used the same way bring in$36 at the end of the year. The energy saving bulb would thus pay for itself after 3 months, however because of the higher cost a strong lumen led lamp only after half a year.
Old bulb: 100w*4h*365days*$0,31/1000=$45 a year
CLF: 20w*4h*365days*$0,31/1000=$9 a year| savings = $36 a year
LED: 11w*4h*365days*$0,31/1000=$5 a year| savings = $40 a year
But not only incandescent lighting should be replaced, power-hungry halogens should also be removed in favor for more environmental alternatives. Unfortunately these cannot be substituted by CLFs but LED technology will on the other hand work very well here.
As mentioned at the beginning of this article, the television is a device where the energy consumption is highly dependent on individual habits of the user. A new energy efficient appliance can really save money for a family that has a sofa sitting , popcorn eating TV watching lifestyle. If you and your family fit into this criteria, it would be useful for you to focus more closely on the energy efficiency labels when out shopping for a new one.
A more efficient TV with a decrease of 100 watts in energy consumption would mean a saving of $91 per year, if the TV is used daily for 8 hours.
To those who consider great energy savings to be of particular importance could find that selecting a TV with a smaller screen size is beneficial. In this way not only is the initial purchase cost is reduced but there will also be a smaller energy bill to accompany the TV.
When purchasing energy efficient appliances
Always weigh the pros and cons well when purchasing new energy efficient appliances for your home, as a more efficient new purchase will not be profitable in every household. When calculating if the extra costs when more power is consumed by an old appliance will justify the expense in buying a new energy efficient appliance, the results will always be individual.
