Oil is especially important not only because of its density, but also because of its portability and versatility. No other form of energy can be transported and utilized as easily as oil. Most of us are familiar with oil in the form of gasoline or diesel, but perhaps also in kerosene or fuel oil as well. Natural gas is actually higher in density, but requires slightly different storage and engines. This portability and versatility explains why so many power tools such as lawn mowers, chainsaws, spin trimmers, lawn edgers, and more are powered by gasoline. The same advantages are also why most cars, trucks, tractors, agricultural machines, mining equipment, and roadbuilding equipment all use gasoline or diesel as ...

However, in this particular instance, I do think it reflects an issue connected to the wider sense of what this blog is all about - accepting predicaments we have little or no agency over.
