- revelation 11y agoMerely refining oil into gasoline already has an efficiency of less than 90%.
- anigbrowl 11y agoMarginal doesn't necessarily mean small, but that it's proportional to the overall cost. In economics your fixed costs (eg the cost of building and equipping a factory or an oil field or whatever) go down as a percentage of unit price as you produce more goods, whereas your marginal costs are a function of production (eg transmission losses, taxes, raw materials, labor-per-piece).
