Could a more convenient form of energy transfer/storage than electricity be possible?

I was thinking about the progress that has been made in terms of energy usage for e.g. transport purposes and noticed how the prominent source of energy had changed over time: first muscle power, then wind & water power, then steam power, then diesel power, then nuclear power.

Similarly the method of transporting the energy has also changed, first being conveyed directly, then mechanically and then electrically.

As is widely known, electricity is a highly practical medium for storing, transmitting and transforming energy.

Would it be possible, from a physical point of view, to have something better than electricity in the (perhaps ever-distant) future for these means?

Perhaps something using quantum mechanics?

Edit: With better I mean any improvement in miniturisation, power transfer, efficiency and flexibility that would not be possible using electricity.
