How much gas does a generator use

Whenever we intended to buy something. We do a market search for this purchase. During the market research, we conduct price comparisons between the various available devices in the market. This comparison is based on the features of the product. Finally, we are able to find a product that creates a perfect balance between the features of the product and the price of the product. But is this the right way of buying a product?

No unfortunately not, even instead of this fact that this is the way most of us adopted it.  even though that is the wrong one. Then what is the right way? 

The right way is to choose the product based on the above mentioned criteria plus the operational cost of the product. Sometimes it happens that the operation cost of the machine is too much and you are not able to bear it. While the initial cost of the machine is too low. In a local language of the subcontinent, that is Punjabi this situation is illustrated as you have longer mustaches than your beard. So to avoid this type of situation you must include these seven questions discussed in this article while you are searching for the product. 

This article is specifically written for the gas generators so you may modify the below narrated questions as per your own need. Here we have written these questions for the people who are intended to buy the gas generator in near future.

The Seven important questions to be asked in the market research for gas generators

The Answers to these questions must be sorted out while buying the gas generators. These eight questions are crafted by a team of expertsChampion Power Equipment 76533 4750/3800-Watt

  1. How much gas does a generator use per hour?
  2. How much gas does a generator use in a day?
  3. How much natural gas does a generator use?
  4. How much gas does a 2000 watt generator use?
  5. How much natural gas does a generator use per hour?
  6. How much gas does a 4000 watt generator use?
  7. How much gas does a RV generator use?

Here question number one is  “how much gas does a generator use per hour?” is important for those people who occasionally use the generator. Sometimes they have an alternative source. So by comparing the per hour cost they will be able to find out if this is suitable for them to buy a generator or not. Alternatively, they can still move on with their old generator or alternative source of energy

Here question number two is  “how much gas does a generator use in a day?  This is important for those people who are intended to use the generator for a longer period of time. These generators can be used at camping sites, building sites, or any other place. Where there is no electricity available and you need to rely completely on the generator. For these circumstances, you should know how much it will cost you to run a generator for the complete day.

Another situation other than the camping site is the RV van. You may have an RV van and you need a power source for your RV van as well. In this type of situation, The generator will again run for a longer period of time. By calculating the cost you will be able to know that should you buy that generator under consideration or alternatively you may use the other options like the solar panels to generate the energy. 

Question number three in the list is  “how much natural gas does a generator use?”  This is important for those people who are intended to use the generator with a fixed connection. This may happen in the house or even at a production unit. At both these places, the natural gas connection is available. This natural gas connection can be used to power the generator.

The price may vary from area to area. Even sometimes at the same geographical location. The prices of the gas may vary. This depends on the usage of the gas. If you use the gas for domestic purposes. The rate charged will be different if you use the gas for commercial or industrial purposes. So if you are thinking of buying a generator that runs on natural gas and you have the intention to run it on the fixed connection of the natural gas. Do consider this fact while calculating the operating cost of a natural gas generator. 

The next question in the list is  “how much gas does a 2000 watt generator use?”  This is important for those people who are intended to buy the generator as per their energy requirements. These energy requirements are less than 2000 watts. This is always wise to calculate your energy requirements wisely. You should also include the increase in the energy requirement that may happen in the near future. 

This is not wise to change the machine again and again. As when you sell the machine this will definitely bring some loss to your pocket. Buying a new machine will definitely cost you time and effort with the money. So try to calculate the power consumption accurately. If you think that it is appropriate this is really a wise idea to hire a professional for the estimation. These services are even available online and you may easily hire the one at your convenience.

The next question is again about the per hour consumption  “how much natural gas does a generator use per hour?” This question is important for the people who intended to use the fixed natural gas connection to run their generator. This type of question has already been discussed before. The difference here is that previously we have discussed the all day long consumption of gas. Now we are discussing here the per hour consumption. This consumption cost is important for those people who have an intention to use the generator for a relatively short period of time. 

If the generator is needed for a short period of time then remember there are other alternative sources of energy available. As you need the energy for a shorter period of time this means that comparatively, you require less energy. Do consider this fact too, that is it wise to spend money on the generator while your energy consumption requirement is for less quantity.


The second last question of the list is again related to the energy consumption calculations. In exact words, the question is that “how much gas does a 4000 watt generator use?” So this question will be important for those people whose energy requirement is less than or equal to the 4000 watts.

Same advice as we have given to the people whose energy requirement was less than these ones. That was the 2000 watts. The added part does not over calculate your estimation. If you are using the machine at the underperformance level this means that the initial cost you spent to buy the machine is in vain. Therefore always calculate your consumption, accurately and buy the machine according to it. 

Over consumed machines will be torn off very soon. While under consumption machines are truly a waste of money. So do not waste your money and choose wisely. 

The last question of the list is related to the people who own an RV. In exact words, the question is that “how much gas does a RV generator use?” Naturally, this question is for the RV owners or for the people who are intended to buy an RV in the near future. In both cases, this is an important question to consider. As the generator may be the only power source your RV has. This can be problematic if the generator is unable to provide the energy to the RV vehicle especially when it is night.

The answer to this question also depends on the size of the RV and the appliance with which the van is equipped. 

We recommend you to use solar energy panels with your RV. As these are environmentally friendly and if used intelligently will definitely decrease the expense for the energy generation. 

Rough Estimate of the Consumption

This depends on lots of things. But here we will provide you with a general estimation of the gas consumption. Remember that usually two types of gas are used in the gas generator: one is natural gas and the other is propane.

Gas generator Consumption (Natural Gas)

These calculations are made for a  7-kilowatt generator that operates on natural gas.

  • The per hour fuel consumption if calculated in cubic feet is 118. Please remember that this is a rough estimation.
  • Based on the current Natural gas price that is $20.40 for every thousand cubic feet. If you operate the generator for a complete day of 24 hours. The cost will be around $58.75

DO remember that this estimation can be changed as the prices of natural gas may vary from location to location.

Gas generator Consumption (Propane)

These calculations are made for a  6-kilowatt generator that operates on the propane.

  • The per hour fuel consumption if calculated in gallons is 1.42. Please remember that this is a rough estimation.
  • Based on the current Propane price that is $3.38 per gallon. If you operate the generator for a complete day of 24 hours. The cost will be around $115.19

Do remember that this estimation can be changed as the prices of the Propane may vary from location to location.

Final Words

Buying a generator is a one time expense. The running cost on the other hand is a continuous expense. So this is not a wise decision to manage the one time expense and leave the continuous expenses unattended. 

This article is written with the purpose to introduce the readers to various aspects of this consumption cost. Please remember that here we are dealing with the gas generator only. Moreover, the assumptions we have made are based on the assumed prices. If the price of the gas is less in your area then the consumption cost will be less than the estimated value. On the other hand, if the prices in your area are higher than the estimated cost naturally then the actual operating cost will be higher than the estimated cost.
