Question

what have been the changes in the use of energy and material and its impact

Answer 1

As the service industry has grown and diversified, there has been a rapid rise in the share of energy and material costs in provision of services. Services, which have traditionally been considered immaterial by their nature, are now absorbing substantial amounts of energy and material goods.
The energy industry has become increasingly aware of the importance of environmental protection and is working to reduce its long-term impact. Getting the energy or material we need affects our environment in many different ways.
