On the ratio of equipment costs to operating costs
Thread Content
When calculating the annual total cost, what is approximately the ratio between the energy consumption cost (i.e., operation cost) and the equipment cost for those of you who are experts? For example, I calculate that the cost of the equipment is 100,000, but the operation cost is 1 million – that’s a difference of 10 times. Is that reasonable?
It’s quite normal; for example, a 1-kilowatt light bulb costs 100 yuan. The electricity cost is 50 cents per kilowatt; if the lights are on for 1,000 hours a year, the electricity cost will be 500. This is more than the cost of buying bulbs
Is it reasonable for an electric stove bought for a few dozen dollars to consume much more electricity than a computer bought for several thousand dollars? Calculated based on the cost per unit of equipment, an electric furnace should consume less than 1 watt of power. Would anyone actually buy such a furnace?
