Are dishwashers more efficient? (with examples)

There has been ongoing a long argument whether dishwasher or hand-washing is more efficient in terms of water and energy.

Whereas some people consider that dishwasher is more efficient than hand-washing, some also think, at the same time, that hand-washing is more efficient.

Whatever the discussion goes on, it is actually a matter of water and energy consumption, the use of time, the number and sizes of dishes, etc. Based on these matters, the efficiency of the dishwasher or hand-washing matters. 

Hence, analyzing some fundamental aspects of dishwashers and hand-washing, I’m going to find out the best and most efficient method of cleaning dirty dishes. So, here you are. 

Are dishwashers really efficient (energy & water)?

Apart from every debate, there is no denying that using dishwashers than washing by hand is more energy and water-efficient.

Dishwashers are manufactured with the advantages of not only reducing your labor and saving time but also saving water as well as energy. Every brand has intended to ensure this facility.

Whether your dishwasher is energy and water-efficient or not depends on the method and frequency of your uses. As dishwashers are equipped with multiple wash cycles and options, you can select anyone according to your preference.

As a result, some choose to pre or post-rinse dishes and some leave the tap running continuously. That is why it may consume a lot of water and energy as well. 

Nevertheless, most of the new dishwashers can consume 11-15 liters of water per cycle which is nine times less than washing by hand.

Clearly speaking, while hand-washing may take up to 27 gallons of water, a dishwasher consumes, at the same time, up to 3 gallons per cycle. Research shows that an Energy Star certified dishwasher saves more than 5000 gallons of water per year. 

And in terms of hot water cost, whereas every wash cycle can cost up to $0.30, the annual cost of almost 200 wash cycles may reach $60 on average.

It proves that dishwashers are really water-efficient in terms of saving a huge amount of water annually. 

Afterward, dishwashers are also energy efficient since they have got Energy Star Certification. A dishwasher runs on from 1.5 to 1.8 kWh of electricity that may cost around $0.20 per load.

So, if you run your dishwasher 5 times a week and 250 per year, the energy will cost more than $50 yearly. On the other hand, the cost of hot water when you apply hand-washing will cost you around $100 per year.

That is why it is easy to realize that dishwashers are more energy-efficient. 

Is it cheaper to wash dishes by hand or use a dishwasher?

Because of excellent competence and different benefits, washing dishes by a dishwasher is cheaper than washing by hand. A number of remarkable facts show that a dishwasher can save a lot of money lessening the cost of water and energy. 

As I’m going on to say, a dishwasher depletes around 3-4 gallons of water per cycle which is really different from hand-washing which consumes almost 27 gallons.

Just think what a big amount of water a dishwasher can save per load. By doing so, it can minimize your water cost significantly. 

Moreover, it also can save your energy cost since it is energy efficient consuming less energy. When you run the dishwasher after full load, it will reduce your cost more noticeably.

Therefore, it is quite evident that washing by a dishwasher is cheaper and more reasonable than washing by hand. 

Do dishwashers use a lot of electricity and increase electric bills?

Since dishwashers run on electricity, people think that they may devour a lot of energy and increase the cost awfully. But this long-term misconception has now been clarified that they do not use a lot of electricity and increase the bills. 

A dishwasher runs on 1200 to 2400 watts on average. Typically, it proceeds on using 1500 and 1800 Wh. In this case, it costs between $0.13 and $0.20 per load.

So, if you run your dishwasher 5 times a week and 250 times in a year, the annual cost may exceed $50 on average. 

Hence, regarding the cost of hand washing, it is not an extravagant figure of money. 

How much does it cost to run a dishwasher every day?

As I’ve hinted before, washing dishes in a dishwasher saves cost by consuming less energy. Since running a dishwasher per load can cost between $0.13 and $0.20, the annual cost can range up to $50 only. 

However, the cost can vary according to the rate of electricity, the duration of load, and the workload. To capture the estimation of the cost, there is a table showing the matters more clearly and precisely.

As an illustration, if you run 1600kWh of electricity that costs $0.08, it can cost $0.128 per hour. So, if you run your dishwasher for 2.5 hours per day, the cost will be $0.320 per day. Therefore, the yearly cost will be more than $116. 

Now, see the chart to know the cost more exactly.
