Answer to Question 1

No, the infrastructure for coal involves much more earthmoving than, for example,
oil production.

Answer to Question 2

True. There are trips for the purpose of recycling, there is the energy cost of
remelting the metals or glass, etc. Overall, however, recycling saves energy.
