What is "on-demand" saying in the following?
In addition to their energy density and on-demand nature, another reason that we've relied so heavily on hydrocarbons is because they are easy to store. Coal sits in a pile, oil in a drum.
Is this saying "we can use hydrocarbons whenever there is a demand on them"?
I believe they mean that the energy is easily converted to our uses when we want it. We don't have to prepare anything in advance. We just go to our cars and start them and go. The energy is usable when we demand it.
