LP Gas vs. Electric

Today I discovered something truly amazing.

It all started with a notice I got from the LP gas company last week. It said that gas prices will rise by 30 yen per cubic meter. That got me to thinking about ways I could reduce gas use. I could only come up with two things that I use gas for, though:

1) hot water (for the bath, etc.)
2) cooking

So starting this week, I have been taking completely cold showers without any bath to accompany them. That saves on heating water.

The other one, cooking, was more difficult. I decided that if I ever need to boil water, I would first heat it in my denki pot to 98 degrees before moving it to the gas stove. I tried to come up with ways to use one pot to accomplish two things simultaneously. I even thought for a while how to use my rice cooker for cooking more than just rice.

But then today, it hit me.

Why not figure out how much it actually costs to use gas for cooking?

After some calculations, I realized that depending on which burner I use, it costs either 122.88 yen or 216.83 yen per hour to have the burner running at full speed.

Although I don't actually cook that way, it gave me something to use to compare to electric stovetops.

I had heard for some time that electric is cheaper to use than LP gas, but I always just took that on faith and never bothered to do the math for myself until today.

For comparison purposes, I decided to figure out how much a 1400W burner would cost at similar conditions my calculation of gas burners. The result was a mere 30.268 yen per hour running at top speed.

Let's compare:

Gas: 122.88~216.83 yen per hour
Electric: 30.268 yen per hour

I think I'm switching to electric!
