southern MN | Liquid fuels have a relatively high cost but are very energy dense and very portable and very storable. They make a great fuel for transportation!
Gaseous fuels like natural gas and solid fuels like coal are much cheaper if you need heat in a stable location. They aren’t nearly as portable but they can be set up to be cheaper in a location.
You wouldn’t use gasoline or ethanol to create heat in a building. Economically.
You wouldn’t use coal to power a car or bus.
Not economically in today’s world.
Each fuel type has it’s good and bad points, and until recently the people in charge understood these differences and we used each to their best features as an intermesh of multiple energy sources to give us the best bang for the buck and a reliable sustainable overlapping power system.
Ethanol is a good economical contributor to our mobile fuel supply. That is its strong point.
