The site doesn't specify it well, but this is cost for a given level of illumination, not cost for any level of illumination. It takes a lot of firewood to produce the same amount of light as a regular lightbulb. Heck, it takes a lot even compared to an oil lamp. I read "The Prize: The Epic Quest for Oil, Money, and Power" by Daniel Yergin some time ago. One of the things that struck me was just how much of an effect kerosene lamps had on society. It was the main use for oil in the early days, and indoor lighting went from expensive whale oil (or dirty, still-costly tallow) to cheap, abundant kerosene. It provided hours more leisure time every night in the winter. |
