Expert Answer:

They travel similar to water waves in a lake or waves on a string.
 
Whenever a source emits an electromagnetic ray, the waves travel just like water ripples would travel in water. They do not require any material to be present in order for the energy to be carried forward.
 
There is no need to consider energy transfer for these waves like one does for water waves on lake.
