Short term vs long term. Trains will always be more energy efficient than planes. Once everything become electrified, we'll need to be smarter with what we use

Short term vs long term. Trains will always be more energy efficient than planes. Once everything become electrified, we'll need to be smarter with what we use our energy for. Does it make sense to waste it on lifting something into the air or sailing it across metal?
