If a car is powered by electricity, however, the energy has to be stored in batteries that have a much lower energy density than gasoline does. To carry 300 milesâ worth of energy, an electric car would need a lot of very heavy batteries.
Humans harness energy conversion processes to provide energy services.Energy demand is derived from preferences for energy services and depends on properties ofconversion technologies and costs. Energy commodities are economic substitutes.Energyresources are depletable or renewable and storable or non-storable.ire, providing heat and light, is. a process by which chemical energy stored in the fuel, say, wood, is converted to thermal. energy and radiant energy.
